nbc news political editor mark murray is joining us a little later on. his reminder, primary performance doesn't always match what happens in the general election. his analysis ahead right here at 6:45. >>> 6:06 now, irs workers based out of the headquarters building in downtown washington will have to work remotely this week. the building remains closed after a fire on monday in the basement. no other offices are affected by the closure. and tax processing is still under way. you have until the 18th. news4, a d.c. firefighter now finds herself needing the community support after a fire destroyed her home. 21-year-old tonnisha morris's home caught fire on easter sunday. she made it out but lost everything. >> it's jut like we just like se bottom with nothing. i'm thankful for the job i have. i would actually think we started at nothing. >> if you'd like to help morris, you can take donations to engine 28 near the cleveland park metro station. >>> allergy season is upon us. but is your child's runny nose a sign of that or something more serious? the signs

here to give us all the details, nbc news senior editor mark murray. good morning to you. let's start with the republican race here in new york. where do things stand? >> jose, in our nbc/"wall street journal"/marist poll, it shows donald trump is at 54%. that's an important number because if he's above 50% in all the congressional districts, he could walk away with all of new york's 95 delegates. you have john kasich in second place at 21%, and ted cruz, the winner of wisconsin a week ago in at third place at 18%. >> and is that 54% more or less than what other polls in the past have shown him to have here in new york? >> yeah, jose, the polling has been very consistent in new york. every single poll that i have sign over the past two weeks has shown donald trump above 50%. of course, how much he is above 50% is going to be key for him to get all of those delegates. but right now, donald trump is in the clear driver's seat in this contest. >> so mark, let's talk about the republicans on a national level. how is trump doing there? >> you know, trump's leading but not as mu

mark murray joins us now. we keep hearing about trump and that magic number.g into the convention, will he have it or not. >> he needs to win in these five states by big if he runs the table and his percentage is more than 50%, he has a good shot of racking up about 100 delegates tonight out of 118 available. he does that, that's step number up with. step number two is almost the superdelegates in pennsylvania on the republican side. these folks are free agents. there's 54 of them. some say they'll be determined by how the vote goes. but it becomes an arm twisting type of moment. donald trump has to prove he can win some of these people over. and then third he has go into indiana and beat ted cruz. if he does that he has a glide path. if he falls short on one, it's a battle to the convention. >> this cruz/kasich alliance, was this their idea or somebody in their campaigns? >> they realized they do something to shake up the race. this wasn't much of an alliance. the whole deal was john kasich said i'm not going to campaign in indiana, but i still want my people

so much of this comes down to geography and demographics and just depends where you go. >> mark murraypreciate it. >>> today the d.c. council plans to take an emergency vote on whether to allow senator bernie sanders on to the democrat being primary ballot before the democratic party missed a inappear work filing deadline meaning currently his name is not on the ballot. if d.c. council reverses that, you will get a breaking news alert on your nbc washington app. approval from mayor muriel bowser. >>> and our coverage of decision 2016 is far from over. be sure to stay with us to hear what chuck todd is watching for in wisconsin today. >>> three seconds at mid court. gives it to jenkins for the championship! >> storybook ending from villanova over north carolina all thanks to kris jenkins. josh hart landed 12 points to help the wild the cats get the win. >> just wanted to tackle him. it's amazing. i'm at a loss of words. >> just like the rest of us. one of the greatest finishes really in ncaa championship history. north carolina's nate britt is from upper marlboro. he may not have been o

. >> now, let's bring in nbc's mark murray to break down the numbers. >> andrea, almost, the voter andntries are saying none of the above. 68% of all american voters end up saying they could not see themselves voting for donald trump and you have 61% of them saying the same thing for ted cruz and hillary clinton. andrea, one of those three people will end up being the president of the united states unless something shocking absolutely happens. the question becomes, how does that person ends up governing. these are numbers that we have not seen before. americans are saying they don't like any of these people right now. >> what do you attribute hillary clinton's negatives just jumping up the last month. >> it is democrats and particularly bernie sanders' voters who's becoming much more negative for him. that's up from our past poll and to put that in perspective, we never saw that kind of number when in the bruising 2008 between hillary clinton and barack obama. their favorable numbers were in the positive territorial by their arrival side. there is a situation and casey was aleutilottin

in cleveland, that's the recipe to help those numbers just a little bit. >> mark murray for us in nework, mark, thank you. we want to get back to this flooding in texas now. deadly flooding now and at least five people, perhaps, six have been killed in and around the houston area. this is a live look in spring, texas. this is spring texas, we are about 25 miles northwest of houston here. some dramatic rescue, we watched them play out in the past 30 minutes. we have seen emergency workers are hoisting men and women and some elderly, hoisting them to safety here. the united states coast guards have been called into help. nbc charles hadlock is covering the storm for us. charles, we know this is an area that you know very well, what are you seeing and hearing? >> what you are seeing is cyber creek. it runs north of houston between the town of cypress and spring. this area received about 17 inches of rain in a short amount of time yesterday and they're still dealing with the flooding here. cypress creek is about 10 feet above the top of bank right now and that's enough to push into homes

. >>> mark murray is a senior political editor for nbc news. he joins us now. i want to start where we just ended with tracy and president obama's comments about hillary clinton. should we read into that. >> one of the things you should read into that wasn't part of the clip is president obama repeatedly praising hillary clinton. he hasn't endorsed her, but he's coming very closely. also as far as the e-mail investigation, aaron, i think what we've seen so far is a very deliberate, very slow process from the fbi and the justice department to check everything. politics plays a role. that won't do anything to take away concerns critics have, but i think the administration wants to conserve that every part of due diligence has been put on this issue. >> ted cruz and donald trump won over the weekend. >> donald trump is a favorite. many polls have him at 50% where heig delegates. i was on the ground in wisconsin where ted cruz had an overall advantage, and he cleaned up. it also showed donald trump's disorganization. they had misspellings for delegates, they had pe

. >> mark murray is nbc's senior political editor. ere was a big fight b w brewing about what rules were going to govern the convention. there's also a lot of rumblings in all sorts of directions abiliabout the big steel as some trump accolades put it. big steal. >> it was really -- you're referring to the dust-up over the rnc rules for the national committee almost create a road map what it would be like in the cleveland convention. it's important to point out those would not be the rules we would end up seeing in cleveland. that has to be done by delegates themselves who end up arriving in cleveland. around july 11th, about the week before the republican convention, those delegates who sit on the rules committee will go in and craft the rules. a lot of them have to do with who's qualified to be on the ballot and how many ballots, pretty much any rule it would end up being on. what happened this weekend, the little dust-up isn't as significant as july. just as significant how every delegate matters, every rule will matter in this conv

our senior political editor mark murray joining us to play what this is about. not telling his supporters to vote for ted cruz. so wdo the parameters that were outlined on sunday were that john kasich said i won't campaign in indiana. ted cruz, i'll give it all to you. and ted cruz says i won't campaign in states like oregon and few mexico p. but as john kasich mentioned, he's not telling his supporters not to necessarily vote for ted cruz in indiana. and so some mixed signals. and one other important hinge worth noting, indiana has had early absentee voting already. so many ballots have already been cast before it alliance was made. and so the kind of question is it going to work and we'll find out a week from today. of course we're so focused on tonight's five primary contests, but indiana is shaping up doing a big race. >> we'll keep an eye on if. and many people questioning why bernie sanders is staying in this race. and whether tonight could be the deciding factor of what he does next. >> i think fewer people actually saying that bernie sanders should actua

let's bring in mark murray. we are just starting to run through it there. the sanders position right now in the state, it is tough to figure because if you look at the map going forward they will probably win states. if you are the sanders campaign like why quit? but the delegate math looks worse this morning. >> also the map, too. they might end up winning in a place like oregon but hillary clinton will be strong in kentucky. april 26th contest sanders campaign can say we will overperform in pennsylvania but hillary clinton will have a double digit win in maryland. we saw this between barack obama and hillary clinton. here is what to put in perspective. you mentioned right now hillary clinton has about a 240 delegate lead in pledge delegates over bernie sanders, that is twice the amount that barack obama had over hillary clinton this point in 2008. given that proportional nature where you can win by five percentage points or 15 percentage points you only net a handful of delegates. that is the difficult math for the bernie sanders campaign. >> we are heari

. >> mark murray who spends his da days on capitol hill has been following the boehner/cruz relationship for years. it's not a huge surprise there is no love lost between these two men. in ted cruz really trying to repaint -- i shouldn't say repaint, but really trying to frame the relationship. he went out of his way to say maybe i met him three times, we never had a substantive discussion. how much does that help ted cruz with his base and the people he's looking to bring along with him? >> ted cruz is really trying to take advantage of this and turn lemons into lemonade, john boehner along with nancy pelosi, harry reid, kind of looping them into all of washington, saying washington is against me. in a lot of ways, that is very consistent with ted cruz's tea party type message. message to the house freedom caucus. he has so many endorsements from so many members of the house freedom caucus. but one of the limitations going toe to toe with john boehner here as well as the washington establishment is that for ted cruz to be able to beat donald trump and unite the other parts of the republ

to dive into the numbers, we turn to senior political editor, mark murray. new york, the most expensive market in which to advertise, as we know. what kind of media buys should we expect to see from candidates? >> we're going to see much bigger amounts, as this goes on, craig, because new york is so expensive, particularly in the new york city area. little less expensive when you go upstate. but what i find really fascinating on the democratic side, we're seeing parity numbers, both bernie sanders' campaign and hillary clinton's campaign spending $1 million each. in the last contest that we ended up seeing in wisconsin, it was bernie sanders with the overwhelming ad spending edge, so you're seeing the clinton campaign dip into its wallets to be able to bring bernie sanders to parity because bernie sanders' big strengths over last few months being able and having potential to outspend her in state after state after state. >> last three months straight managed to outfundraise her as well. we use the numbers but don't talk about the amount of money that comes i

with msnbc news poll, mark murray.we've been talking about the 30% of the sanders supporters who say they would not vote for hillary clinton. how serious of a problem is it? >> it's serious, andrea. and what's striking is you have 30% of the sanders voters who would not vote for hillary clinton in a general election. just 15% of clinton voters say the same of sanders. so a 2-1 where the sanders crowd is more anti-clinton than the clinton crowd is anti-sanders but i think a little bit of perspective needs to be put on this. we saw similar numbers in the 2008 election. you remember hillary clinton versus barack obama contest very well and at the end of the day, the clinton forces, their voters mostly came back into the democratic fold. i think the expectation would still be the same if bernie sanders falls short to hillary clinton and his supporters go to her in the general election. but do note that what is occurring with sanders and his supporters are a lot outside of the democratic party. bernie sanders has not been a

. >> and, kristen, our own mark murray was watching that exchange. he said what he saw there was bernie sanders playing to a national liberal audience that maybe is a little more sympathetic to the palestinian side, hillary clinton was playing to a new york audience that might have a different take. >> undoubtedly and secretary clinton unequivocal in her support of israel and its actions and what is so fascinating about that moment, i think, steve, is it underscores this broader trend we're seeing in new york which is that secretary clinton trounces senator sanders when it comes to the jewish vote. stunning of course because he is the first major jewish candidate for a presidential election. it underscores one of the themes that is really starting to define the race that we're seeing at least here in new york. it also comes as we're learning that senator sanders suspended his jewish outreach director. again back to that point that you raised from mark murray, he is speaking to a very specific segment here in new york, throughout the country, a libera

mark murray, nbc's senior political editor. mark, thank you so much. >>> a few moments ago we were talking about this ted cruz event here in new york city. we just got some video in from this event. someone was escorted out just a short time ago. this was moments ago in the bronx. we are watching this video for the first time with you again, ted cruz expected to take to the microphone there any moment now. this was a disruption at the event. we don't have audio there, so we don't precisely know -- he was actually speaking in spanish, so we don't know exactly what he was saying. but vaughn hilliard was there at that event. we're trying to touch base with him and find out precisely what went down there. someone just escorted from that ted cruz event here in new york city. we'll get you an update on what happened there in just a few moments. i'm joined right now, though, from washington by former john mccain adviser, adolfo franco. also author of the the wilderne wilderness. mccay, let me start with you. i want to play something t

mark murray joins us from washington with all of that. we have a candidate who says he's winning, who likes to read poll numbers from the stage. do you see any evidence that there is a polling problem for him? >> you know, ari, two things are actually happening on the polling front for donald trump. one over the totality of this election. and this has been going on for a year. donald trump has gotten popular with republicans, and his popularity has grown. all the polling, including ours, shows that more than half of republicans say they could see themselves supporting donald trump. the other thing that's occurring is that the wider electorate, the -- you know, basically, your general electorate, doesn't like donald trump at all, and he's grown more unpopular. and particularly unpopular with key segments of the democratic base. and we're talking african-americans, latinos, women, voters 18 to 29. you end up seeing about 8 in 10 of these folks having an unfavorable view of donald trump. our own nbc news/"wall street journal" poll from earli

this is our own senior political editor mark murray on the uphill climb for sanders. >> reporter: both cruz and sanders now go to terrain which is much more unfavorable to them. next contest two weeks from now that's problematic for bernie sanders not only because hillary clinton, that is her own state, but it's a closed primary. and bernie sanders, one of the secrets to his success has been winning all these independents that can end up voting in new york. >> reporter: so independents, young voters, have boosted sanders to victory in a number of states now. new york could be a different story, and that one is coming up real soon now, in less than two weeks. in washington, i'm tracie potts, news4. >>> a giant leap for the purple line today. maryland could soon approve the contract to get it built. it's a $5.5 billion contract that will pay several companies to design, build, operate and maintain the line. when it's all done, the light rail line will connect prince georges and montgomery counties between new carrollton and bethesda. >>> tom, it's warming up a little out there. we can't

joining me with his break down the delegate math is nbc news political editor mark murray. mark, the delegate rules for each state have been different and distinct and bewildering and confusing. give us a quick rundown on what the new york rules are. >> the new york rules are if you end up getting 50% more statewide and also in every single of new york's 27 congressional districts, you can win all 95 delegates that are up for grabs. i think everyone realizes that donald trump is going to do very well tomorrow in new york. the only question is how much. i have him projected about getting anywhere between 75 and 85 of new york's 95 delegates. the way for ted cruz and for john kasich to really keep donald trump below 95 and all 95 is to be able to hold him down at a congressional district here or there, keep him below 50%. if they're able to do that, they'll be able to steal a handful of delegates. >> and so my understanding is if they can win a few congressional districts and keep him under that 95, people are expecting he'll win big. it's part of the reason we've seen kasich

joining me now, nbc news senior political editor mark murray and bringing back abby phillip. f all, she is way in front in our poll and all the other polls in new york with this primary just next tuesday. tomorrow night's debate could be that pivot moment, the last chance for bernie sanders, but then he is going to roam for two days. a bad bit of scheduling. >> yeah. and you never know on these types of things, andrea. i was just struck hearing hillary clinton and her message to african-americans and such an important constituency for her. she is leading bernie sanders among african-americans by 68% to 28% margin, 40 points. it's even higher in recent maryland poll that our nbc affiliate here in washington, d.c. ended up doing. and so this is really her base support. it explains why she has a very, very big lead and it's so interesting to see her addressing this audience, just an hour ago, bernie sanders was walking a picket line, going to his base, so that kind of campaigning in the final days, of course, right before bernie sanders goes to rome and before tomorrow's debate.

and mark murray, senior political editor for nbc news joins us now with more on tomorrow's primaries and the new team effort against trump. so what do you think about that? explain what it is they have in mind. can they take themselves out of a primary? >> so here are the parameters of the deal. we're either calling alliance or truce between john kasich and ted cruz. they're promising john kasich will not campaign in indiana, allowing ted cruz to be able to go mono y mono with donald trump in that state. and what kasich gets out of it is cruz promised he campaign in oregon and new mexico. but this doesn't necessarily mean that they're telling their people to vote for, you know -- that kasich is telling his voters to say, hey, be sure to vote for ted cruz. they're not saying that. >> and they can't take their names off the ballot. >> they can't. and they're trying to do the best they can. but the recognition donald trump is leading, and, barbara, he's leading in indiana right now three consecutive polls donald trump up. and donald trump wins there it's game over. >> let's take a liste

nbc news senior political editor mark murray has the break down of the delegate grab. numbers that show just how close these candidates are to try to get to the magic number of 1,237. trump needs 60%. cruz needing 87%. kasich out of it this way. is there room for cruz to catch up to trump? >> well, alex, when you look at ted cruz being able to catch up to donald trump it really is a convention strategy that you would have in cleveland. you see the math 87% is very difficult with the 800 or so delegates remaining overall. so it is very difficult. i think the name of the game is being able to try to stop donald trump. he is at 60%. if he is able to win all of new york's delegates a week and a half from now that can go down about 53% or 54%. what we are seeing here in colorado springs is an example of ted cruz's organizational might and donald trump's organizational weaknesses. so far ted cruz and this campaign able to get 21 out of 21 delegates up for grabs. we will sigh 13 awarded this afternoon. ted cruz will be addressing this convention here. the thing is you see so

. >> nbc news senior political editor, mark murray, joins us with more. ion from ted cruz. in the beginning, he was swatting away the idea of an open or contested convention. he's seemed to have evolved a bit as the delegate math makes it more and more likely that's where we're headed. >> yeah, that really is his best path to the republican nomination, chris. according to our calculations, ted cruz has to win 88% of the remaining delegates to be able to hit that magic 1,237 number, to be able to win an outright majority. so it's still mathematically possible, but very, very difficult, particularly when you compare it to donald trump needing 56 to 58%. and to me, the biggest challenge for ted cruz tomorrow is not only to be able to win in wisconsin, but to be able to win all of its delegates. to really start narrowing donald trump's delegate lead and make it very difficult for donald trump himself to hit that 1,237 magic number. there is a possibility that ted cruz, if he wins the state, can actually win all of the delegates, all 42, because not only is it

. >> mark murray and jacob soboroff, thank you so much. when our live team coverage continues this saturday, donald trump is making his first appearance in days, stepping out of trump tower in new york city, as ted cruz is sweeping away delegates in colorado, as we were just talking about. is this a sign that trump is slipping? we'll discuss that and more, plus get an update on today's big breaking news out of belgium, the lone suspect wanted in connection with the brussels airport bombing, now behind bars. that breaking news coming in today.

i want to bring in msnbc political editor mark murray. as we make sure everybody is in lockstep with the cleveland convention in july. let's talk about where delegates stand right now and who has got the clearest path? >> reporter: right now it's donald trump who has the clearest path, but that's certainly not a very easy path at all. as hallie was putting it very well, he needs 50% of the remaining delegates to hit that magic 1237 number. thomas, i've actually been looking at the possibilities over the next several contests over whether or not donald trump gets there. i know steve kornacki has been doing his, and i come up with just short of about 1,200 delegates for donald trump, which means he needs to cobble together about 40 or 45 of the unbound delegates, the uncommitted, and nbc's decision desk, we have about 120, 150 or so. so that means donald trump needs to win about 25 to 35% of these people to be able to hit that magic number. and i would argue that if donald trump is close to 1,237, he's about 30 or 40 away, it's doable so he

. >> hallie jackson and mark murray, thank you very much. >>> this news of ted cruz calling on carly running mate comes as donald trump and hillary clinton have been trading fire. donald trump slamming hillary clinton saying she's playing the "woman card" all when she responded to one of donald trump's criticisms of him. >> mr. trump accused me of pl playing the quote woman card. well, if fighting for women's healthcare and paid family leave and equal pay is playing the woman card, then deal me in! >> i think the only card she has is the woman's card. she's got nothing else going and fra frankly, if hillary clinton were a man, i don't think she'd get 5% of the vote. the only thing she's got going is the woman's card and the beautiful thing is women don't like her, okay? look how well i did with women tonight. okay. >> this morning the clinton campaigned fired off a fund-raising memo saying his rhetoric has created a volatile atmosphere. let's bring in emily, supporting pro-choice democratic women. first, i have to get your take on this announcement we are going to hear in just about

i want to bring back in nbc senior political ed tor mark murray. talking about the headline here, is the bigger headline not so much that bernie sanders wins wyoming, no big surprise really with that, but is it how close it was would you say is the headline here? >> yeah, frances, i think that's fair. i think that this is something that both sides can actually be very happy about. bernie sanders ends up getting the win as he was expected to do, really continues to end up having momentum going into the new york primary on april 19th. but hillary clinton kept it much closer than expected. one of the reasons why what was going on in wyoming was a closed caucus. and you end up having independents were not as able to participate. and that is actually very instructive and important as we head into new york because new york is a closed primary. that actually might give you a sense that hillary clinton is going to be your favorite in that contest because when you take independents away from bernie sanders, it really dilutes his success. he's been able to c

mark murray for us this afternoon, thanks as always. >> thanks erika. >> we want to introduce you now, the republican has received threats ever since speaking out hashly about donald trump. he said the threat began after this quote about whether he could ever support donald trump. "if satan was one vote away from the nomination, i would consider voting for trump if he was the only conservative. >> i received hate e-mails to my business and political accounts a craig dunn is joining me now, good to have you with us today sir. >> good afternoon, erika. >> i know you have detail some of the things you have been called and you have been called the traitor and enemy. the biggest traitor. ast all because you made the mistake of expressing your opinion. you would be required to vote for him, is that correct? >> i am a district delegate and in indiana we award three delegate votes for every congressional district one. on the first ballot if mr. trump won the first indiana district, i would be required to phovote him. >> which you said you would do following the rules. what would happen next i

joining us, sara murray, cnn politics executive editor mark preston, peter beinart and rebecca berg,tical reporter for real clear politics. you heard paul manafort say that, yes, corey lewandowski is the campaign manager, but he, manafort, reports directly to donald trump. >> i think that's an important message that he's sending to washington insiders that he's in control of trying to get donald trump to 1,237 delegates that's needed to win the nomination. paul manafort well known within republican circles. very known here in washington, d.c. had he looked subservient to lewandowski, i don't think that would make him effective. >> rebecca, you wrote an article saying these other republican senators are very reluctant to get in there and endorse ted cruz. he's got two, maybe three supporters so far that have publicly said they'll support him. what's the problem here? >> so reluctant is maybe a generous word to use in this case. they all genuinely deeply dislike ted cruz. even with trump surging and on his way to potentially winning the republican nomination or being in a strong positi

murray. now i want to bring in cnn's chief political correspondent dana bash, and cnn politics executive editor mark preston. why are you smiling? we're like the circus has already come to town. politics this season is crazy. >> no more elephants in the circus, though. >> dana, since you're out on the campaign trail, i want to ask you this. this idea of teaming up to stop trump, people find it a little odd, a little more than a month ago you told us the kasich team was pushing for an alliance. they even got mitt romney to make a call. but then cruz didn't have any time for it. he couldn't be bothered. what changed since then? >> not just that he couldn't be bothered, don. more importantly, his campaign team thought it was a crazy idea because at the time, let's say a week ago, they thought that -- and they actually rightfully did still have a mathematical path to the nomination before the convention. that no longer exists, thanks in large part to the fact that right where you are in new york, ted cruz got zero delegates last tuesday. so new it is time for ted cruz to try to be more strategic, and th
