and skits prennia. that is not necessarily the case. it could be a me too drug that is in every drug similar to a previous drug. we don't know what they spend their money on. they are enormously profitable, spend a fortune on lobbying and campaign contributions. >> thank you very much. that is "all in." rachel maddow show starts right now. >> thanks to you at home for joining this hour. on a norwegian island 800 miles from the north pole deep underground, there is a vault. it took decades to conceive, years to build. it has been operating there for seven years open. 2008. but the idea of this vault is that it should stay in operation until the end of days. and i'm not even really exaggerating by saying that. the idea is that this vault should be there for us humans as a species when inevidentbly the we humans do something so dumb

or maybe some asteroid does something so cataclysmic to the earth that whatever humans are left on earth will need to deliberately re-create from scratch the things that make human life possible and sustainable on our wretched wrecked little planet. on that norwegian island way up in the arctic what that vault holds are seeds. seeds as many diverse human food crop seeds as possible. hundreds of thousands of them in deep freeze buried in an underground vault at the north pole. so if, say, we have a global nuclear war or some international global pandemic that kills almost everyone or some radical global cataclysm that does humans in in some other way, at least there's this. at least there's there one deep vault that hopefully has been

able to protect the seeds for basic survival crops like beans and rice and wheat. so maybe some day as a species, even after a global cataclysm we will be able regrow ourselves a human future. thanks, norway. i mean, coming up with an idea like this takes a pretty dark view of where humans are headed. what we are capable of doing to this planet. they call this thing the doomsday vault. after all. that said, it's nice to have. right? i mean, it's nice that somebody is thinking about the value you have keeping us humans around as a species even if things really do go that pear shaped some day. well, today, as the religious leader of the catholic church as pope francis made the first visit of his lifetime to the united states where he's expected to address both the

united nations in new york and in washington, the government of the most powerful nation on earth, he will be the first pope to ever address a joint session of the u.s. congress while he is here on this trip. today as pope francis arrived in the united states to start this historic unprecedented visit, up at that vault, deep inside that arctic norwegian island, today, somebody for the first time ever made a withdrawal from the doomsday vault. the syrian city of aleppo for years has been home to a central regional seed bank where they keep seeds for food crops and crops crucial for live stock which can grow even in the most dire drought conditions in the middle east. the seed bank in aleppo is a crucial source of drought resistant seeds for wheat and barley and important grasses. syrian civil war is grinding into its fifth year now.

that crucial seed bank in the city of aleppo is apparently one of that war's casualties. so now as of today, they have formally requested to please withdraw some of the doomsday seeds from that vault in norway to make up for what has been lost in that war. the first time the doomsday vault has ever been tapped. that civil war in syria has killed a quarter million people so far. it has forced 11 million people to leave their homes, most of them fleeing for their lives. that's half the population of that country, 11 million people. so many people have been killed and forced out of various parts of syria now that it is starting to appear that whole swathes of syria are being depopulated of civilians. and those poor civilians have now become an issue for the rest of the world. the european union today made a controversial decision to try to settle 120,000 of those syrian civilians in various european countries even though some of those countries who were in on the decision really do not want to do it.

and amid all of these intense headlines today, right, the moral imperative to care for these desperate people, the logistical and economic issues how to care for them justly, the creepy feeling we humans are flirting with the end of the world by having to access our doomsday plans, amid all of that happening in the physical world and moral universe today, today comes the visit by this new pope. arriving in the united states for his first ever trip to this country. first ever trip to the u.s. not just as pope but the first ever trip to the u.s. in his life. after he became pope in 2013, you might remember that the first trip that pope francis took outside of rome was to a place called lampedusa. lampedusa is an island that is part of italy by way off the italian coast in the mediterranean sea, closer to

northern africa than anything else. lampedusa has become an international by word for desperation. lampedusa has for years now been a desperate way station for migrants and regulars trying to flee their own countries for their own survival or for a better life trying to get to europe. and the very first thing that pope francis did after he became pope was that he traveled to lampedusa to make pack common cause with these most desperate people in the whole world. and top pray for those of them who had been lost at sea trying to get there. so any pope coming to the united states at any time is a huge deal for this country where basically, a quarter of the american population is catholic in one way or another. but this pope coming to this country at this time is a truly singular thing. given who he is and given what else is going on in the world. and so his alitalia jet touched

down today at andrews air base. president obama was there to greet him in person along with the first lady and their daughters sasha and malia obama also their grandmother, the first lady's mother was there in person. the whole family was there along with the honor guard and lots of vatican officials and lots of american officials and a few very excited, a few hundred very excited people who got special tickets to be there from what effectively is the vatican's embassy in washington where the pope will be spending the night tonight. the few hundred people at andrews were shouting for him, francisco, francisco. they shouted for him several different chants in spanish welcoming him to the united states. this pope's first language, of course, is spanish. but then the crowd at andrews today, this is very sober occasion, this very statesman-like occasion. then there's this crowd. at one point, the crowd got to the point of the american football style chants.

i'm going to quote directly here, the crowd at one point shouting who, who, hey, hey, welcome to the usa. which was awesome and then as the pope was getting into his car, listen to this one. [ crowd chanting ] >> we love francis, yes, we do, we love francis, how about you. like there's an opposing team on other side of the bleachers or something, right? an opposing team they're challenging for the strength of their people love. it was awesomely american. all of it, including the chants in spanish. including the one that felt like maybe there were cheerleaders involved about to do a pyramid with pom-poms. and then at that point in the visit, look, he got into what i think we must consider to be the world's tiniest beast. you know how they call the presidential be limo the beast? here, for example, this is the beast. this is the -- do we have the president's car? the armored presidential limo?

there's, on the right. that's the president's armored limo. that's the beast. look at the pope's car in his tiny little fiat 500. he rolled the windows down. and he left in that tiny little car for the motorcade to the church and the embassy venue where he will be spending the night. and then starts a truly exhausting but for american catholics and for a lot of other people a very exciting series of events. some of which are going to be really, really huge. i mean, tomorrow the pope is going to be welcomed at the white house at an event that is not only expected to include the president, it's expected to include another 15,000 people. at 11:00 a.m. tomorrow, there's going to be what they're calling a papal parade, basically a popemobile motorcade through the streets of washington, d.c.

that is an unticketed event but people have to go through metal detectors and get there early in order to get close enough to see the pope on that parade. many thousands of people are expected to do that. we'll have to see how many when people turn out. he'll do i an prayer service in the middle of the day with catholic bishops. tomorrow afternoon at the national shrine of the immaculate conception, there will be 30,000 people expected while the pope canonizes father junipero serra. that will happen before 30,000 people tomorrow. that's all tomorrow. the following day on thursday morning, he is going to do something no pope has done before. at 9:20 on thursday morning, the pope will deliver a joint address to congress. nobody knows exactly what the subject is going to be. pope francis obviously has strong political-ish opinions on a number of issues considered to be highly charged issues in the united states.

honestly, if you want to know what to anticipate there from his previous trips to other countries, i think it's fair to say we'll talk about this with e.j. dionne later on. if you look at what this pope has done even as he has made politically charged pronouncements on a number of controversial issues when he has traveled to other countries, he has avoided hitting too many domestic political hot buttons directly when he visits other countries and makes public remarks. maybe that's a way to set our expectations for that congressional speech. but again, who knows? no pope has spoken to a joint session of congress before. we have no idea what he's going to say or view the import of that opportunity. it's never happened before. every seat inside congress and all the galleries will be filled for na historical address. they're also expecting 50,000 people outside. 50,000 people and that's just in

the ticketed area. outside the west front of the capital. top both watch that address toes congress on screens they're going to set up outside and also to see the pope in person as he is expected to come out to the speaker's balcony at the capitol and wave and make some short remarks after his formal speech. to get a sense of the scale though, in addition to the completely full capitol, in addition to the 50,000 people who have tickets to be at that event, who else doesn't have a ticket that's going to show up? nobody knows how many more thousands of people will show up outside the ticketed area in hopes of watching him on the screen and catching a glimpse of him while he's there. after his address to congress, the pope is not doing some high falutin event with high ranking politicians or the president or something. he's made the decision he will then go have lunch with homeless people at a downtown washington, d.c. catholic charities venue. and then after that, he will set off for new york city and do a vespers service on thursday night.

that will be the first of several new york events where there will be crowds of people there to see him and participate in these events but the public at large won't have any large scale access to him. that's going to be true at the vespers at st. patricks and when he speaks to the united nations and goes to the 9/11 memorial and he will visit a school in east harlem friday at midday. then at 5:00, it's going to be another popemobile parade this time through central park on friday. and again, for security reasons, they have set up a cordon around where the pope is going to be for that will popemobile motorcade through central park. you will need a ticket to get inside that cordon. get this new york city has handed out ticks just to see the pope drive through central park. they have handed out 0,000 tickets. just to see him drive through. and then at 6:00 on friday night where is he driving to is madison square garden where he

will say a mass at madison square garden in front of a capacity crowd of 20,000 people. that's all by the end of this week before he gets to a weekend full of events in philadelphia that's going to include a mass before an estimated 1 million people. on sunday afternoon. so this is an event. i mean, this is obviously a religious event. it is a cultural event. on the east coast of the united states, it is a huge security event. but it's impossible not to acknowledge it's also a political event. not just because of the views of this pope and their political implications but also because of the places where there are intersections and not

intersections between the views of this pope and the views of our own politicians including our president. today, at andrews air base, it was not the first time that this pope and president obama have met in person. president obama was at the vatican last march. he met privately with pope francis at the vatican last year. it's interesting, there's always an exchange of gifts at meetings like that. famously at that visit to the cat can, what president obama brought pope francis as a gift was a seed chest. was a handmade botch full of seeds from the white house garden. seeds for fruits and vegetables and some people in our country criticizes president obama for that gift and yes, as gifts go if this is how you judge them, that is a fairly cheap gift. but for this pope, i think that was probably the right tone. and for all the issues on which

this pope and this president disagree, for all the pope's religious conservatism on issues like abortion for example and gay rights, part of the reason this papal visit to the united states feels like such a big deal on such an important moment for our country whether or not you're catholic is because of the ways this president and this pope really do see eye to eye on big and controversial issues the ways in which these two leaders are aligned. which in turn explains how we ended up in a place where the country at large seems pretty psyched about this big visit by pope francis and there are tens of thousands of people turning out to see himmer from he goes. it may very well be a million people who turn out to see him in person in philadelphia. but maybe it's because of the large scale alliance between our president and this pope on some big important ideaologically charged issues. maybe that's why. even for all this enthusiasm for

this pope on this trip, the american political right is not that psyched to see him. >> i just think the pope was wrong. and so the fact is that his infallibility is on religious matters, not on political ones. >> everyone's got to ride the pope now. the pope stay with his job and let us stay with ours. >> i don't get economic policy from my bishops or my cardinals or from my pope. >> i would just say that this, that the church has gotten it wrong a few times on science. i think we probably are better off leaving science to the scientists. >> the most dangerous person on the planet is somebody who is seeking strange new respect from their adversaries. that is what the pope is doing. he doesn't want to be your grandfather's pope. he wants to be modern. all he needs is dreadlocks and a dog with a bandana and he could be on occupy wall street. >> pope francis comes. there's a translator there. he says mr. trump, this is very nice. the translator says to you, the pope believes that capitalism can be a real avenue to greed, it can be toxic and corrupt. he's shaking his finger at you when he says it. what do you say in response to the pope. >> i'd say isis wants to get

you. do you know that isis wants to go in and take over the vatican? that's a dream of theirs to go in to italy. >> are you talking about capitalism? you scare the pope. >> i'm going to have to scare the pope. >> i don't think the pope is scared of any american politician. but with our country transfixed by this historic visit, and the american right basically against him, this has a weird moment and a big moment and sort of and i think an unpredictable moment in american politics and in american culture. and to some people, it probably feels like the end of the world. but so far, it's been really fun. so today, at the same time, we had pope francis landing in

so today, at the same time, we had pope francis landing in the united states for the first time ever and we had former secretary of state hillary clinton making a major policy announcement. happened at nearly exactly the same time. you never guess which one got more attention.

of january 14th, no, january 4th, 1919, president woodrow wilson happened ob in paris negotiating the treaty to end world war i. while he was there, while he was in europe, he decided he would make a side trip to rome and he in 1919, became the very first u.s. president ever to visit the vatican to meet with the pope. he met with pope benedict the xv. december 6, 1959 president eisenhower went to the vatican to visit pope john xxiii. when john f. kennedy, so far the only catholic president our country has had, when he was

planning on visiting the vatican, an the pope at the time was so excited to meet with him that he sent him this private letter which presidential historian michael beschloss tweeted today. among other things the letter praises the many admirable qualities that have made the united states a leading member of the family of nations. the next president, of course, was lbj. and when lyndon b. johnson visited pope paul vi, president johns was thoughtful enough to bring the pope a gift and the gift that he brought the pope was a bust of himself. not a bust of the pope. but a bust of johnson. nice to meet you. here's a statue of me for you to remember me by. the first american president who ever received the pope at the white house was president jimmy carter in 1979. >> good afternoon.

and good morning. this is washington where the pope arrived this morning. is going to be in washington throughout the day in a short time, he will go to the white house where he will be greeted by president carter and a group of officials and others. the first time this has ever happened. he is running a little late. >> and he will say to the president of united states that he comes too late because of you. >> late or not, pope john paul ii was the first pope to ever be welcomed to the white house. president george w. bush traveled to the vatican more often than any president has.

he went four times in all during his presidency. when pope benedict, this pope's predecessor, when he visited washington, president george w. bush famously gave him a ginormous four-tiered lemon birthday cake. happy papal birthday. president obama met pope francis for the first time last year at the vats can. today president obama and his family greeted pope francis on arrival at andrews can along with vice president biden and jill biden and their grandchildren. the vice president is known to be devoutly catholic, vocal about his faith throughout his time in public life. tonight is this pope's first ever night in the united states. the first thing on his agenda tomorrow morning is to meet with the president obama at the white house. along with 15,000 other well-wishers. joining us now is "washington post" columnist e.j. dionne. he covered the vatican for years for a number of times. it's great to see you.

thanks for being here. >> i love your celebration of this visit. >> it is a big deal. i mean, i feel like it's important to note that you know, popes have been here before and presidents and popes have had interesting political alliances. it's not that the only thing that's unprecedented here is the address to congress. but is there a reason that a million people will turn out in philadelphia, that there is this address to congress, that there are some so many meetings that are so high profile and that so many people will get so many opportunities to see him? is that the way papal visits go? >> yeah, i mean i think all papal visits have a couple things in common. one is lots of catholics get excited, turn out in large numbers. as you pointed out in the intro, they cheer like they're at a football game. so -- but the other common thread especially in recent years is that lots of people look at well, what impact will this have on our politics? it's not just this pope that we raise that question about. what impact will he have on the church itself. and i think that one of the reasons this visit is so important is not so much that

francis is taking the church in an entirely new direction because he's still as you pointed out, has the same views as the church always has had on issues like abortion. but he las said very specifically we, meaning the church, cannot insist only on abortion and gay marriage and contraception as the central issues. he said we need a new balance. his new balance has involved reclaiming the church's strong position on social justice and dealing with poverty. and he's talked about global warming a lot and issued a powerful encyclical on it. he's talked a lot about welcoming immigrants. we're not accustomed for the last 20 years for the catholic church to stand so strongly and vocally on issues that we tend to associate with the progressive side of politics. and that's creating a special form of excitement and among

some, not all conservatives but as you pointed out, some conservatives a certain amount of anxiety. >> e.j., why is this pope addressing congress specifically? no pope has ever done that before. is this the first one who thought it was a good idea? >> you know, it basically comes because of speaker john boehner's invitation. we finally elect a john kennedy. standing behind him tomorrow will be the catholic speaker of the house and the catholic vice president of the united states. it gives you hope that some of our prejudice against muslims we're seeing out there, that this too will pass in our country. but i think it is largely because of boehner. but also because this pope has had such a powerful voice on

these issues and also has demonstrated something that it's not just the talk. you pointed out he's going to visit catholic charities here. he's not going to some fancy ball. he's visiting with immigrants and people who wash cars and migrant workers when he's up in new york. and so i think this pope has a particular standing, and you know, any conservative who cares about the poor as well as most progressives has to respect that. >> e.j. dionne, "washington post" columnist, thank you. you've been so eloquent. not only reading your past coverage of pope john's visits but also in your previous coverage on these issues. >> thank you. >> much more to come tonight. stay with us. tylenol® 8hr arthritis pain has two layers of pain relief. the first is fast. the second lasts all day. we give you your day back. what you do with it is up to you. tylenol®.

we've got lots ahead tonight, including hillary clinton taking a position on one very big, very controversial issue she has previously refused to discuss. that story is coming up next. and presidential candidate carly fiorina today picked the scariest word possible for the scariest possible topic in the news. it's a big news day politically and otherwise. stay with us.

[ scanner beeping ] sir, could you step aside? "sir"? come on. you know who i am. progressive insurance? uh, i save people an average of over $500 when they switch? did you pack your own bags? oh! right -- the name your price tool. it shows people policy options to help fit their budget. [ scanner warbling ] crazy that a big shot like me would pack his own bags, right? [ chuckles ] so, do i have the right to remain handsome? [ chuckles ] wait. uh-oh.

there's a lot ahead tonight on what's going on in 2016 politics now that scott walker has dropped out of the race. carly fiorina is surging into territory that scott walker used to occupy and the top tiers of republican contenders. but carly fiorina made a terrible remark today on the campaign trail that is probably going to follow her around for a while. we've got that on tape today and that's still ahead. but today on the democratic side

of the race, former secretary of state hillary clinton made news. she made big legit news by coming out finally against the keystone pipeline. she starred off explaining why she had previously not said what she thought about the keystone pipeline. she had not said whether or not she favored it. then she explained she couldn't wait any longer. >> i was in a unique position having been secretary of state, having started this process. and not wanting to you know, interfere the ongoing decision-making that both the president and secretary kerry have to do in order to make whatever the final decision might be. so i thought this would be decided by now. and therefore, i could tell you whether i agreed or disagreed. but it hasn't been decided and i feel now i've got a responsibility to you and other voter who's ask me about this. and i think it is imperative that we look at the keystone pipeline as what i believe it is, a distraction from the

important work we have to do to combat climate change and unfortunately, from my perspective, one that interferes with our ability to move forward to deal with all the other issues. therefore i oppose it. and i oppose it because i don't think -- [ applause ] i don't think it's in the best interests of what we need to do to combat climate change. >> first time she's ever made that statement. on the day that pope francis arrives in the u.s. after his landmark encyclical on climate change, everybody wondering if climate is going to be the subject of the pope's historic joint address to congress the day after tomorrow, on that same day, basically at that same moment, former secretary of state hillary clinton sticks her neck out on this issue in a way she has never done before on then symbolically important and literally important tar sands pipeline that would cross our

entire country. if has been the most controversial environmental issue in the country for years now. and then she went further. to talk about not just why it's a bad idea to build that new giant cross-country oil sands pipeline she also said we ought to work on our existing oil and gas infrastructure since it has developed a nasty habit of blowing up all the time now. >> we already have a lot of pipelines that are leaking. they need to be repaired. they are dangerous. they are leaking methane, they are at risk of causing damage. so i want to put thousands of americans to work who are not only going to be fixing those old pipelines but also we've got railcars transporting oil. i want those railcars and the rail beds and the rail tracks they're on to be repaired. >> democratic presidential candidate hillary clinton today

coming out against the keystone pipeline for one, also saying that she as a presidential capped is in favor of doing the infrastructure work we need to do to fix the old leaky pipelines we have now saying we should fix our railroads and train cars so american energy production involves fewer previews of armageddon in the local news. i could be wrong is, but i think this might be first time this issue has been mentioned in this year's election. this is front porch politics going national. stay tuned.

in the 2008 campaign, one of the turning points in john mccain's run for the president zi was when he was asked at a veterans event about iran. and someone responded by singing a beach boys song into which he substituted the words, bomb, bomb, bomb, bomb, bomb, iran. >> i guess my question is how many times do we have to prove that these people are blowing up people now, never mind if they get a nuclear weapon, when do we

send them an air mail message to tehran? >> here, here. >> he you know that old beach boys song, bomb iran? you know, bomb, bomb, bomb. anyway. >> that was the 2008 campaign. john mccain, republican candidate for president of the united states. today it was republican presidential candidate carly fiorina who at an event today seed to suggest dropping not just a bomb but a nuclear bomb on iran. but then she took it right back right after she said it. she said she actually meant something totally different. >> republicans in the meantime, many are saying oh, i would let this deal stand. i would see if they're cheating. for heaven's sake, they've been cheating for 30 years. beyond that, if ever there was a time for the nuclear option, boy it's the iran deal.

if ever there was a time for the nuclear option, let me explain. let me explain. i realize that might be confusing. the nuclear option in terms of senate process. >> oh. oh! bomb, bomb, not, i mean not bomb. i meant bon-bon. carly fiorina spoke at the citadel today in south carolina. nuclear, nuclear, i don't mean that kind of nuclear. ben carson today was in ohio. jeb bush in iowa. kasich on late night. donald trump with colbert on cbs. hillary clinton made headlines when she came out against the keystone. we should make the infrastructure fixes. but on the republican side right now, as all these people campaign in their different ways, well or poorly or creatively, the question that's now hanging over almost all the

republican presidential contenders is the question of who is going to quit next. we starred off this presidential season within 17 republicans running for the presidential nomination. the first one to poof off the list was rick perry. he quit last friday, september 11th. it was ten days later that the second candidate quit. that was scott walker who quit last night. this pace keeps up, if one republican candidate quits every ten days from here on out, everything will wrap up in a neat fashion because that ten-day schedule would have the 16th republican presidential candidate dropping out on february 8th which would be the night before the new hampshire primary at which point we would be down to just one republican candidate and everything would be settled. it's not likely to go that smoothly. but this once every ten-day pace at which republicans at least currently are dropping out of the race, the question of who is

going to have the resources to stay in for the long haul even if they all continue to lose badly to donald trump, that is kind of the dominant thing to watch right now in the republican race. and in the 24 hours since scott walker dropped out, the most interesting thing on that issue that has emerged about him quitting the race last night is that apparently, it was a total surprise to almost everybody in scott walkerville when he quit. this is from the hill today. look, scott walker's wealthiest donors are still in shock after the wisconsin governor stunned all but a tiny circle with his decision to terminate his campaign. as recently as thursday, scott walker had assured donors that the campaign was in it for the long haul, they had a strategy to win. their campaign team was solid. on sunday, the day before he dropped out, his top donors were still busy making calls to try to get people to come to the next round of walker fund-raisers. even top donors and fund-raisers had no idea he was getting out. the next day, boom, scott walker was out with no warning. one donor who just gave $200,000 to his super pac told reporters

today he learned the news that scott walker was quitting from a reporter. "i had just got out of a meeting and got a call from a reporter telling me about it. all of a sudden, calls started pouring in. i would say it was surprising." another donor whose family donated $5 million to scott walker's super pac apparently also felt blindsided. according to a scott walker advisor. that donor was in the middle of organizing a huge bundler event for walker in a couple of weeks. another donor said he had just left a voice mail message for scott walker on friday with advice how to improve his campaign. that message went unreturned. "it's the first time he hasn't called me back." another big-time scott walker doaner who had recently hosted and i reception for governor walker says he felt similarly ignored. "i did not get a heads-up about this decision." i felt like i had gone to the wall for him. i was surprised that he didn't consider me to be within his

inner circle to give me a heads up to trust me. since the very beginning of the campaign, scott walker has done better than almost anybody else in terms of attracting very large donations from very, very rich donors. by the end of july, his super paccing had raised more than $20 million. they thought they'd have $58 million or $40 million by the end of this year. right up till less than 24 hours before he dropped out of the race, his super pac was still raising money. having been shocked by his decision to drop out, the super pac now says they're going to give their money back to the donors. so maybe that's good news for donors. they're getting their money back. on the other hand, they also perhaps righteously seemed kind of mad about the whole thing. i mean, scott walker now leaves behind a bunk of money and a bunk of people who wanted to keep spending money on him but who now feel like when they picked him, they chose to throw good money after bad. and they are angry at the way the whole thing ended up. so what happens to all those

folks and their fat wallets? are those republican donors going to give their money to anybody else or did walker just alienate his donors from the process? that's one interesting question. what happens to scott walker's many billionaires? in terms of his actual campaign staff, a few staffers have already recommitted to other campaigns. none of these moves are likely to be that conscious sequenceal. the highest staffer who has gone to om other campaign so far is one of his campaign co-chairs in new hampshire who went to marco rubio. sort of sounds like a marco rubio coup till you realize that scott walk ser polling an the 1% in new hampshire. guy who is the co-chair of that effort probably isn't going to make much of a difference to anybody else's campaign. there is one place those that might have the biggest ripples in terms of scott walker getting out of the race and that is iowa. iowa was where scott walker was concentrating most of his efforts. he was down to 5% by the time he

dropped out of the race. before he started failing in iowa and everywhere - they now feel like when they picked him they chose to throw good money after bad. at the way the whole thing ended up. what happens to all of their folks and their fat wallets. are they going to give money to anybody else. honestly, scott walker's staffer who has gone to some other's campaign so far, as far as you can tell is one of scott walker's co-chairs in new hampshire who wept to marco rubio coup . you realize scott walker is polling at 1% right now. the co-chair isn't going to make much of a difference to anybody else's campaign. >> there is one place that might have the beingest ripples in terms of scott walker getting out of the race. he was down to 5% among republicans in the state of iowa before he dropped out of the race. but before he started failing in iowa and everywhere, scott walker had been a front-runner in iowa for a really long time, a long enough time that it leaves a mark. for example, if you look at the iowa state senate, fully 1/3 of the republicans in the iowa state senate are signed on officially as scott walker

supporters. scott walker planned on winning iowa. his campaign got in there early. they sent a bunch of staff there, they grew their organizing effort there. this long member of the iowa political establishment signed up for scott walker while he was still looking strong there. what happens now. just without . so you can drink all you want... ...with no discomfort? exactly. here, try some... mmm, it is real milk. see? delicious. hoof bump! oh. right here girl, boom. lactaid®. 100% real milk. no discomfort. and for a creamy and delicious treat, try lactaid® ice cream.

>> we're committed to iowa and this will help us make the case all across the koun tr i. >> scott walker said he was putting all his eggs in a basket of iowa. that was a week ago, less than a week ago. then last night he quit, quit the race all together. joining us no uh to talk about whether him quitting changes the race in iowa is a political columnist in the iowa paper that also held an editorial board

meeting today. thank for having me rachel. scott walker did put all of his eggs in the basket of iowa. much of his staff was working there, many of his efforts were focused there. does him leaving leave a hole in iowa, leave space that other candidates are going to move into more than would be true in the rest of the country? >> well, he did have a little bit more support in iowa than he did in the rest of the country, as you said. the last poll showed his support around 5%. if they splinter to everyone some go to rubio and some go to bush, some go to ted cruz and maybe some go to ben carson or carly fiorina. it's going to have a very -- it's going to diffuse and there's not going to be actually much that you can say. >> a third of the republican in the state senate in iowa were signed on as scott walker supporters. even though he maybe had 5% support across the state, seemed like he did lock up a pretty

good chunk of the rooi aye republican establishment, didn't he? >> i have to say, though, i think a legislator's vote most of the time gets you exact one vote. most legislators are not actually out there working for the candidate. some are. some are. but most are adding their name to a list. and it doesn't really mean a lot. and it probably won't mean a lot when they add their name to the list of the next guy in line. >> it's great to see you, kathy. thanks very much for being here. i really appreciate it. >> all right, we've got more ahead tonight. most legislators are not actually out there working for the candidate. some are. some are. but most are adding their name to a list. and it doesn't really mean a

lot. and it probably won't mean a lot when they add their name to the list of the next guy in line. >> it's great to see you, kathy. thanks very much for being here. i really appreciate it. >> all right, we've got more ahead tonight. please stay with us.

>> next week i will be broadcasting the show from washington, d.c. currently in the grip of pope mania. tomorrow is going to be a really big day. in d.c., it will be pope francis' first day in the united states. he has a packed schedule. he's going to be welcomed in the morning by president obama at the white house. that's an event about 11:00 a.m. tomorrow in which the president is expected to be joined by 15,000 invited guests.

some conservatives have expressed outrage that some of those 15,000 people invited to the white house are themselves gay or lesbian or transgender. we'll see if pope francis cares particularly about that. honestly, it's hard to imagine that the white house would have gone out of their way to make sure to find 15,000 100% straight people to be there, but conservatives are mad that they didn't, i guess. pope francis will then go oen a people parade through the streets of washington, d.c. thousands of people expected to line the streets of d.c. to see them. the pope will take part in a prayer service late in the day. late in the afternoon tomorrow, he will cannonize america's newest saint. the missionary priest will be america's latest saint. native american groups have protested that decision by the pope. that cannonization is expected to be attended by 30,000 people. that's all on top just for tomorrow. the rest of the week into the weekend will be similarly large and in some cases historically unprecedented events by this papal visit.

we will bring it all to you starting tomorrow including live tomorrow night from washington, d.c. we'll see you then. "first look" is up next. >> it's wednesday, september 23rd. right now on "first look," breaking news overnight. american hero and baseball legend yogi berra has died at the age of 90. pope francis was greeted by the first family upon setting foot in the united states. today he begins an all-important task of uniting the faithful and the political. but the war of words among the presidential candidates heats up as the pressure builds to gain and keep momentum. plus bowing to pressure? a ceo reconsiders his 5,000% price hike for important prescription drug. "first look" starts right now. good morning, everybody. thanks so much for waking up with us today. i'm betty nguyen. in a matter of moors the leader of the
