that's it for me. thanks very much for watching. i'm wolf blitzer in las vegas. erin burnett "outfront" starts right now. "outfront" tonight, debate in the desert. hillary clinton and bernie sanders are about to go head to head. plus, bill and chelsea about to hit the trail. will it help or hurt hillary clinton? and donald trump waying in on tomorrow's debate picking winners and losers. that's what he does, right? and why what is missing from the debate, it's actually him. let's go "outfront." good evening, i'm erin burnett. we are live from las vegas. two heavyweights, hillary clinton and bernie sanders are counting down to the showdown that could make or break their campaign. clinton has been practicing. she's been practicing, practicing, practicing with mock

components. bernie sanders said he only started studying reluctantly after two aides sat him down and gave him a talk. we're live in las vegas and begin with jeff zeleny in our coverage. hillary clinton, a lot of preparation, a lot of that would be her personality, how she prepares for things. but the question is, is she nervous? >> reporter: she certainly comes into this debate having more information than anyone before. she did some 25 debates in the 2008 cycle. but tomorrow night when she stands on this stage behind me right here, it's a whole new ball game for her. she has to show that she's presidential and ready for this moment in the campaign. she was a very practiced debater in 2008. she was so much better than barack obama then. it's a different moment in this campaign so the clinton aides tell me they are going to try and present her as presidential, as the grownup in the room, somebody who can handle all of these problems. but this audience behind me,

they are going to be some of her subpoena supporters and democrats about her candidacy. that's who she has to try to appeal to tomorrow night. >> jeff, bernie sanders says he's not preparing at all and obviously as we said, in just the last couple of weeks. is that true, that he doesn't need to prepare, that he's arrogant or is it just posturing? he's preparing and doesn't want to admit it? >> reporter: well, the bernie sanders you see on the campaign trail is sort of the one you get. he's kind of a professor. he's rumpled and really preparing all summer long. he's been doing rallies across the country. in the last couple of days, he actually has been preparing. he's been holed up in a vegas hotel room since saturday night, i'm told, and he's going through policy papers and getting ready for this debate. you don't want to be too practiced if you're bernie sanders. things that people like about him is that he's off the cuff. he will not bring up hillary

clinton unless he's attacked by a name first. so look for that to happen, though, because this is the first opportunity for all of these candidates to mix tup. martin o'malley, the former governor of maryland, he has the biggest set of mixup overall of the candidates, erin. >> something viewers hope will happen. it make it is more watchable. tonight we have new two cnn polls. they show hillary clinton with two leads if two states. one is in south carolina. she has a 50-point lead over sanders there, which is significant, considering some of the national polls showing him gaining sharply. the other here in nevada, does she have her momentum back or not? john berman is "outfront." >> reporter: this, the most recent 13,000 in tucson. she comes back by big new poll numbers in early states. >> our next president, hillary clinton!

>> reporter: tonight, cnn orc polls in nevada and south carolina show hillary clinton with sizeable leads over senator bernie sanders, a big difference from new hampshire where he has led since this summer. high stakes as they prepare to take the stage for the very first democratic debate of this campaign. high stakes but today senator sanders suggested keeping the dialogue on a higher plain. >> let's treat each other civilly and respectfully and let's not try to democrnize people. >> reporter: the 74-year-old self-proclaimed democratic socialist has gone out of his way to be the contrast front-runner. in other words, vote for me, not her. >> i know what i stand for. hillary clinton knows what she stands for. let's have that debate. >> reporter: sanders has yet to do a mock debate. but today for the first time he

practiced hypothetical exchanges with the other candidates and moderator. hillary clinton has been practicing with bob barnett playing the role of bernie sanders. she took a break to celebrate her 40th wedding anniversary and -- >> you never sweat, like physically. >> reporter: have some fun with buzzfeed podcasters. >> you guys are the first to realize i am not really a human being. i was constructed in a garage in palo alto. >> reporter: as for the man they all want to replace, president obama gave his most complete answer yet on the lingering e-mail question surrounding his former secretary of state. >> she's made a mistake. she's acknowledged it. i think the way it's been ginned up is in part because of politics. >> reporter: and vice president joe biden consulted with family over the weekend but no likes

from the white house. >> i'm going to let joe make that decision and i mean what i say. i think joe will go down as one of the finest vice presidents in history. >> reporter: tonight, a notable endorsement for bernie sanders. keith ellison, democratic member of congress from minnesota, one of two muslims in congress, has come out in support of the vermont senator, the second member of congress to endorse bernie sanders. now, hillary clinton has the endorsement of more than 100 members of congress. erin? >> all right. thank you very much, john berman. we'll talk about that later in the hour, whether any of the endorsements get anybody to vote. right now, dave axelrod and dan pfeiffer join me and also joining us, republican strategist ana navarro. spokesman for the congressional black caucus and campaign

committee, doug thornnow. great to have you all with us. hillary clinton is preparing and getting ready. this is a really important moment because there's downside for her. she's the front-runner. >> i suspect that's why there are only six debates because they want to limit the risk there. but i would say this, having been involved where the candidate was doing debates against her, 25 debates in 2008 -- >> 25 debates? >> 25 debates. >> she's a very proficient debater. i wrote a piece for cnn earlier today. i would expect her to do very well. >> dan, the thing is, she's dealing with perceptions of her. she's the front runner but a lot of people don't like her. we call it the word world cloud. what are you words that you think of when you think of hillary clinton? dishonest and outlier.

what can she do to change that? >> this is what republicans think of her. not democrats. the challenge here tonight is to show inspiration. inspire people and right now she has made a very good policy taste for why she should be president. the president is going to be, wait in line ten hours to vote, to knock on doors and make phone calls. that's how you win in a mobilization election. >> she's got to go out there and excite her supporters and remind her why she was getting such strong support a few months ago. and no unforced errors. there is going to be a question about the e-mail server. that needs to be handled with no equivocating. >> she can't be defensive about it. she can neither be flippant or

defensive as she has been in the past. >> that's a good point. staying on the offense. she's not floyd mayweather. he's a great defensive fighter. >> yes. >> she is not. she needs to be on the offense and that's not necessarily going after bernie sanders but that's going after republicans who are just pushing her policy proposals. that's where she is really -- >> i think one of her weakennesses is going to be one of her biggest challenges, to change her position on so many issues. the hillary clinton standing up here tomorrow night could practically debate the hillary clinton from 2008. issues like immigration, on issues like gay marriage and trade promotion authority that she backed away from last week, she's going to have to explain those evolutions and i'm sure people like martin o'malley are going to be right up there trying to emphasize the flip-flops. >> he's got a flip-flop of his own. flip-flops are very, very

damaging but less so when you're flopping over to the popular side and that's the gamble she's made here. i think dan's point is the right one, which is, she has to make people feel like she believes these positions and that they added a up to a coherent message. >> it worked really well for john kerry. >> but how does she have people believe in her as more and more genuine and -- think about the simple passion that bernie sanders, he gets these crowds, 9, 10,000 people. she prefers a smaller room. that's what she gets. but you want to have people feel passionately about you. even democrats, you don't get the feeling there's a lot of passion. >> i think that one of the things that we learn in 2007 and 2008 was -- in 2007, she was the front-runner and very cautious and very unconnecting. she lost the iowa caucuses. she became a different candidate after that when she was not the front-runner. and she became a lot more connected with people, a lot more revealing of herself, a lot

more sympathetic as a candidate. she needs to connect with that person. and i think that's genuinely who she is. but she's not a good front-runner and we saw that in 2008. she can't think like a front-runner. >> so, doug, i'm also curious, she tweeted out today support for the familiar legal of tamir rice, the young boy who was shot in ohio, a horrible admission from the police, saying that it was justified. she met with black lives matter. that case has been going on for a long time and she hasn't said anything about it in a long time. how does she prove that it's genuine and not just pandering to a politically popular point of view right now? >> i think it's the right thing to do. she's going to get criticism from the right no matter what she does. what she said to tamir's family, that was the right thing to do. that's a highly sensitive situation. meeting with representatives -- look, that's the right thing for

her to do. ultimately, she can't worry so much about the criticism she'll get from the right on whether or not she's moved -- saying this or that. that was the right -- that was the right thing for her to do and i think ultimately hillary clinton, she has a passion deficit with her supporters but there is one thing that is going to make her unique on this set and that's the only female running for president and i think that's going to be something that for a lot of -- for a lot of the women out there, it's going to be powerful. >> and we're going to talk more about that coming up. all of you will stay with us throughout the hour. "outfront" next, melania and ivanka trump are running for the campaign trump. where are bill and chelsea? bill just landed here with his wife a few hours ago but you'll never believe who is backing bernie. we have a special report. and trump on clinton's chances in tomorrow's debate. >> she hasn't been a great

debater, i guess, in the past, but she just has to hold. i can't imagine bernie sanders will beater. it's more than a network and the cloud.

more and more people with type 2 diabetes are learning about long-acting levemir®. as my diabetes changed, it got harder to control my blood sugar. today, i'm asking about levemir®. vo: levemir® is an injectable insulin that can give you blood sugar control for up to 24 hours. and levemir® helps lower your a1c. levemir® lasts 42 days without refrigeration. that's 50% longer than lantus®, which lasts 28 days. levemir® comes in flextouch, the latest in insulin pen technology from novo nordisk. levemir® is a long-acting insulin used to control high blood sugar in adults and children with diabetes and is not recommended to treat diabetic ketoacidosis. do not use levemir® if you are allergic to any of its ingredients. the most common side effect is low blood sugar, which may cause symptoms such as sweating, shakiness, confusion, and headache. severe low blood sugar can be serious and life-threatening. ask your doctor about alcohol use, operating machinery, or driving. other possible side effects include

injection site reactions. tell your doctor about all medicines you take and all of your medical conditions. check your blood sugar. your insulin dose should not be changed without asking your doctor. get medical help right away if you have trouble breathing, sweating, extreme drowsiness, swelling of your face, tongue, or throat, dizziness, or confusion. today's the day to ask about levemir® flextouch. covered by most health insurance and medicare plans. you're looking at live pictures of the debate hall where the five presidential candidates will be facing off for the first time tomorrow night on cnn. just moments ago, hillary clinton arrived here in las vegas. bill clinton was with her as they got off that jet. as of now, the former president won't be attending the debate. that's a little strange.

what's he out here for? bill and chelsea clinton are expected to hit the campaign trail soon. the question is, will it help? alexandra field is "outfront." >> reporter: he's her biggest supporter. >> she'd be a very good president and i think she's proving to be a very good candidate. >> reporter: but on this campaign, he's more on the sidelines than outside. >> it's true, i've done markedly less to this point than i did eight years ago when she ran. eight years ago, i did a lot by now of what i've only done two things. >> reporter: months before that, the former president seemed to diminish his role. >> and you're just a bit player to whether secretary clinton runs? >> that's exactly what i am. i'm a foot soldier and will do what i'm instructed to do.

>> reporter: last week he was in virginia where he rallied the base. he didn't talk about hillary's campaign but he kept in line with her message. >> thank you. >> we don't have paid leave, universal preschool, affordable child care. >> reporter: daughter chelsea has also been in the spotlight. she's out promoting her book and also supporting her mom. >> every opportunity i have, i want to tell people why i so strongly supporter her not only as a voter but now as a daughter and a mom. >> reporter: but she's skipping the kind of campaign stops that featured her four years ago. >> thank you very much. >> reporter: there was controversy in 2008 when shells see took on a public role and refused to take most questions and there was more controversy when some of bill's answers tested the campaign's control. >> i think they are being a lot more reserve with bill and chelsea clinton. we are going to see more of them going forward but clinton was a liability on the campaign trail in 2008 and i think they want to

avoid that this time around. you don't want him to interact with reporters and hurt her like last time. >> reporter: like this response. >> no, no, no. that isn't what i said. i always follow me around and play these little games and i'm not going to play your games today. >> reporter: and this unscripted exchange over barack obama's voting record on the iraq war. >> and there's no difference in your voting record and hillary's ever since. give me a break. this whole thing is the biggest fairytale i've ever seen. >> reporter: hillary takes center stage? the first democratic debate tomorrow night. it still isn't clear where bill or chelsea will be watching. >> so erin, we do know that bill clinton arrived in las vegas with his wife by his side. no word on whether chelsea clinton is in town. two big questions here. why hasn't bill had a larger role in the campaign? that's a question that will be asked and answered by a lot of people. the other question is, should he

have a bigger role? does he have any plans to have a larger role? and that's a question that you were able to put to him directly and it's worth reminding all of our viewers that he hasn't taken on a larger role to this point this year because of his agenda, with his foundation. but he did say that he can be really helpful to his wife and attending fund-raisers and that's something that he will continue to do and you will see him do quite a bit more. that's something that he can do. >> alexandra field, thank you. joining our panelist, david axelrod and ana navaro and dan pfeiffer. >> well, he's here to support, i would imagine, his spouse and he doesn't have to be in public to play a major role. he can -- bill clinton is the kind of person, you know, just a

couple bits of advice, telling the story, relaxed, hey, i've got you. that can have a huge positive impact on any candidate, let alone his wife. >> but it does underscore the complexity of the situation because it's unusual that it's here and wouldn't go but you represents a kind of mixed bag for her. he is honestly a very popular person. a world-class politician but he also can eclipse her as he has at times and he's a reminder of the fact that the clintons have been around for a very long time. for those two reasons, plus, what we learned in 2008, i mean, he was an all-star in 2012 for president obama, probably the mvp of the campaign. that's what the president called him. it's different when you're fighting for your own wife. >> caused some problems for her. highly controversial comments. >> he lost it a few times in 2008. >> i see it differently. this time around, i say, let the big dog bark. let the big dog bark. this guy is one of the most

popular people on the planet earth. it's always been, buy one get -- >> i'll tell you why, because he screwed it up in 2008 because he had a very hard time keeping his emotions in check. absolutely. >> just like a lawyer shouldn't be his own client, you know, it may be that he shouldn't be as deeply involved publicly for his wife. >> he's here because the donors want to see him. there's a lot of -- >> sure, that's true. >> -- that go all the way back to the clinton time. some from miami that i know. he loved being with people, you know, shaking hands and visiting with his old supporters. but he overshadows here. that's the simple truth. >> but there's no question, as the campaign goes on, it will be a massive advantage for hillary clinton, when she's in iowa, they'll be in new hampshire and vice versa. he cannot make a mistake because the mistake he makes is

fundamentally different than any other political spouse makes. >> and as long as they are not sharing the stage, as long as he's not introducing her or following her, they are fine. the moment -- >> what is more valuable to her, van? is it president clinton or president obama? >> well, here -- >> who said this weekend he would run for a third term and he could win. >> whoever runs against hillary clinton is going to run against hillary clinton, barack obama, michelle obama. the four of them are going to be on the campaign trail for the general election. i don't think anybody can calculate what it's like to have four superstars on the field. i say bill clinton for every one thing he says, i think they should let him do -- i agree with you. don't put him on the stage with bono, elvis presley or anybody? he's a superweapon for hillary clinton. >> david, we're talking about assuming that there's no joe

biden in this case that would complicate everybody. and you have another beloved democrat. >> he doesn't have to make a choice. he'll allow the primaries to run and support the winner of those primaries. i'm still a downer on joe biden. i think he's doing some of the things necessary to run but i believe him. i believe him when he says he is wrestling with the emotional toll of running for president. we all say, gee, we love joe because he speaks his mind. why don't we believe it when he says i don't know if i have the emotional reserves to make this race. as time goes on, i'm more and more doubtful as to whether it will happen. obviously if she make as big gaffe or there's some sort of upset in the clinton campaign, there will be more pressure on him. >> why don't you think people will believe him? i don't know anybody that doesn't believe that joe biden is being completely transparent and truthful when he talks about wrestling with the decision. >> what i would say about it is

the biggest opponent hillary clinton has tomorrow night is not on that stage. she has got to put on such a clear, commanding performance. this is no reason to get in. i think if she does stumble -- >> reporters and people always ask, what does the vice president mean by that? exactly what he just said. he's the most authentic. >> sometimes it's a consternation. >> he's the most authentic politician. >> absolutely. >> but do you think it's down to the wire when you say he's leaning against it, dan doesn't have a point that he's watching and she seems less than perfect? >> it will put more pressure on him to get in the race but i think the things keeping him out are less about political calculations and more about personal calculation. >> well, we'll hit pause for a moment. next, though, a report shows that barack obama picked up 1 million votes. 1 million votes thanks to oprah when she decided to endorse him in 2008. can anyone pack that punch this

time? and donald trump says he'll be watching tomorrow night. watching but not exactly cheering. >> i'm not running for anybody. i just want to see what they have to say. there are a lot of bad ideas out there. you tuck here... you tuck there. if you're a toe tucker... because of toenail fungus, ask your doctor now about prescription kerydin. used daily, kerydin drops may kill the fungus at the site of infection and get to the root of your toe tucking. kerydin may cause irritation at the treated site. most common side effects include skin peeling... ...ingrown toenail, redness, itching, and swelling. tell your doctor if you have any side effect that bothers you or does not go away. stop toe tucking... and get the drop on toenail fungus. ask your doctor today about kerydin. where their electricity comes from. they flip the switch-- and the light comes on. it's our job to make sure that it does. using natural gas this power plant can produce enough energy for about 600,000 homes.

we are back live from las vegas, the site of the first presidential debate tomorrow night right here on cnn. but even with the democrats headlining, checked in my hotel room today and i looked out and saw -- i saw that. that's really actually all that i could see, that and the sky. you can't escape him. the gop front-runner is literally looming over this debate. sara murray is "outfront." >> reporter: donald trump trying out a new style today, consensus builder. >> the word compromise is absolutely fine. but if you're going to compromise, ask for about three times more than you want. >> reporter: speaking at an event hosted by the nonpartisan political group no labels touted his ideals as prove that he can

bring people together. the gop front-runner facing doubts that an expert in hurling insults can reach across the aisle. >> i'm wondering if the divisive language undermines your ability to -- >> i have to say to you -- you know what, i went to ivy league schools. i know what's divisive and what is not divisive, in all fairness. i don't want to necessarily be politically correct. >> reporter: today, trump confronting questions about how he treats women. >> so if you become president, will a woman make the same as a man and do i get to choose what i do with my body? [ applause ] >> you're going to make the same if you do as good a job and i happen to be pro life. >> reporter: republicans landed some jabs. trump taking on president obama. >> i thought he did terribly

last night. i thought he did not do a good job. i think that our country has nothing but problems. >> what do you think of donald trump? >> he's the classic reality tv character and at this early stages, it's not surprising that he's gotten a lot of attention. i don't think he'll end up being president of the united states. >> reporter: and lindsey graham taking on trump, asking whether his style can succeed in a general election. >> can donald trump bring us together? i don't think hispanics feel that he'll be a good president for them. when 75% of the people don't approve of the candidacy, you're in trouble. >> reporter: even trump can't resist tuning in tomorrow night. he says he'll be watching but he's not rooting for anyone in particular. he'd be happy to take on any one of the candidates in a general election, erin. >> thank you very much, sara. "outfront" not, mike rogers and

dan pfeiffer and david axelrod. in a new poll, donald trump is still at the very top. by the way, really at the top, 27% of ben carson -- almost ten points behind and almost everybody else in single digits. at some point, don't people, people like you in the republican party, need to say this guy has something real? >> oh, listen, i think we've been saying it for a while now. yes, we are in that level -- at that stage of grief right now with those of us who don't like donald trump. we recognize that what is very real about him is him tapping into the frustration and angst that the american people feel at the dysfunction of government. people are fed up and i think donald trump is most definitely voicing that. >> is it true, congressman, if this were jeb bush at this level of the polls, we would all be sitting here talking about how a republican race is done. let's talk about a vice presidential candidate. but with trump, people are not giving it that full respect.

>> well, it's only because of the frustration i think that ana talked about. but i will tell you one thing about donald trump, i represented a union district when i was in congress. if i went to the local hall and had a beer with the union guys, that's exactly how they would talk to me. so he's tapping into something that -- >> it's not so much about the fu function of government but stagnant future and the economy that hasn't worked over the last many decades for people just like that. and he's tapping into that. but it is important to point out that he keeps bouncing between 20 and 30% and occasionally may go a shade under. sometimes he goes to the low 20s. that still means that 20% of the rest are not supporting him and i think the theory is when the field narrows down, there will be a race. the question is, just with whom? >> and remarkable -- >> every poll also shows you that even though hillary clinton and donald trump both have wide margins and leads, they are also

the ones with the highest unfavorable numbers. you know, it's puzzling. >> they are going to have to have a substantive switch. this gets you maybe into the later part of this year and i think because financially he can hang, it gets you there. but when you start not showing up at the latino chambe when you stop -- you can't have a discussion on foreign policy or national security, that does catch up to you and i think those unfavorables start to wash over you. >> i've said it before, the talent runs are harder. that's in terms that he understands. >> to that point, the president also dismissed him as a reality kind of a star. >> yes. >> the president dismissed him as a reality tv star. dan, there's something about that that maybe shouldn't be said so dismissively. let's listen to donald trump defend himself against his tone. here. >> i don't want to necessarily be politically correct all the way down the line. because i'm seeing people -- i

see people, they can't even function. i see politicians that are afraid to say anything because it's not politically correct and they know the answers and they refuse to give them because they are afraid it's not going to be politically correct and i am going to have to be who i am. >> the thing about that is, there is truth in that. >> right. >> it's not just the people reacting to him being honest. it is true. >> look, for an outsider running as an anti politician, he's the best politician running in the party. he's very good at politics. the president hit on what the other candidates should do. he is running a ridiculous campaign and contradictory policy positions and the way to do it is to call him out. the president did this at the white house correspondents' dinner and so i think the candidates are making a mistake when they try to debate him. you know, he says divisive things, that's not going to hurt

him. he used to be a democrat. that's not going to hurt him. call it out for what it is, which is absurd. >> the fact that he's a reality tv star has helped him so very much. he is so media savvy. this is a man who has spent precious little of his huge amount of money on tv because he knows how to work it. he knows how to work the media and get earned, free media. he's also, you know, tapping into the fact that reality tv has met politics. in the year 2015, we have a 24/7 news cycle and logs, records, tumblr, twitter, you name it. he knows how to tap into that very well. >> i would not recommend that republicans go after donald trump. they need to tap into the frustration. his numbers and why he does and folds head-to-head with choinli, the under $50,000 family says something is wrong. i can feel it. my finances aren't getting any better and i'm scared of what i

see. he's tapped into that. if other candidates get into that and tap into that, like jeb bush or -- >> they are good at his. his base are noncollege educated white men. that is his base. it's not enough to win a nomination but it's a strong base. he benefits not just from the experience of being on reality tv but i saw a poll and i wrote about it in which people who watch the apprentice had a 2 to 1 favorable opinion about him. the rest of republicans 1 to 1. he's been building a base for the last 14 years on television. >> you know what is so very interesting about him, how comfortable he is with his wealth. it's something that we've seen with hillary clinton and romney be awkward about. >> and they aspire to that. that's something that -- >> it's like, i made it and i'll make it so you make it. it's a powerful message if you're struggling and sells very well. >> it's also that it's beyond

the people of reach with money. that's part of his appeal as well. >> thanks to all. "outfront" next, candidates chasing celebrity endorsements. do endorsements actually matter? we have a special report. and how just one moment in a debate can make you stand out. woman: it's been a journey to get where i am. and i didn't get here alone. there were people who listened along the way. people who gave me options. kept me on track.

and through it all, my retirement never got left behind. so today, i'm prepared for anything we may want tomorrow to be. every someday needs a plan. let's talk about your old 401(k) today.

we are live in las vegas, the site of tomorrow's presidential democratic debate and tonight donald trump says he's worked it out with steven tyler over his use of the group's hit "dream on" at campaign events. that gives the impression that the band is endorsing trump which it is not. while trump may not have the backing of his good friend tyler, they are trying to shore up celebrity support. kyung lah is "outfront." >> reporter: celebrity always goes hand in hand with presidential politics. then, there's this year. clutching a "people" magazine -- >> i'm hispanic and vote for mr. trump -- >> reporter: a superstar, thanks

to donald trump, the currency of celebrity is taking on a new calculus. >> bernie, president bernie. >> reporter: comedian sarah silverman, not the only supporter of bernie sanders. his campaign releasing this eclectic list of celebrity backers. from the red hot chili peppers to danny devito. also supporting clinton, actress lena dunham and katy perry, even volunteering to write her theme song. >> why does her opinion or anybody's opinion who's a celebrity matter? >> i think celebrity does have currency in kind of affirming your existing beliefs.

if you are waivering wavering about a candidate. >> reporter: remember in 2008, many backed then candidate president obama but this face pumped his polls. >> i'm here because of hi personal conviction about barack obama. >> reporter: an endorsement that a northwestern university study found actually translated into votes. >> the endorsement of oprah winfrey resulted in additional votes in the primary. >> reporter: marco rubio scoring rick hair wry son. >> trust me, i know a good investment when i see one. >> reporter: even star athletes weigh in. dennis rodham who last supported north korean leader kim jong-un said, we don't need another politician, trump 2016. then there's tom brady appearing

to endorse trump by sporting trump's make america great again cap in his locker. >> you think he's got what it takes? >> i hope so. >> brady later said that wasn't a true endorsement of donald trump. so is there another oprah effect on the horizon for this election cycle? so far it doesn't appear to be so because oprah doesn't have quite the same following. erin, we're still kind of waiting to see what happens with other notable celebrities with sizeable followings like taylor swift and ellen degeneres. >> kyung, thank you very much. you know, they have breakthrough moments. that's why we all watch the moment that makes you or breaks you and then, well, there are these moments. >> commerce and, let's see -- i can't. >> the third one, i can't. sorry. oops. what if one piece of kale

we're back live in las vegas where in 24 hours, the five democrats running for the oval office will for the first times square off in the presidential debate tomorrow night and it will be a crucial moment. it could make or break somebody. sarah murray is "outfront." >> i want a build a wall. >> immigration did not come up in 2016 because mr. trump brought it up. >> more energy tonight, i like that. >> as it relates to my bother, there is one thing i know for sure, he kept us safe. >> he's an okay doctor. >> you guys nervous? [ laughter ] >> a few minutes, seconds even on the debate stage can define a candidacy sending contenders soaring in the polls or struggling. this moment in the first republican presidential debate solidifying trump's standing as a candidate who doesn't play by the rules and boosting him even

higher in the polls. in the second gop debate, carly fiorina's cool as ice come back to trump's criticism elevating her. >> i think women all over this country heard very clearly what mr. trump said. [ applause ] >> i think she's got a beautiful face and i think she's a beautiful woman. >> her polished performance rocketing her to second place in post debate polls while the latest polls show her slipping slightly but can deliver a crippling blow. >> the third agency of government, i would do away with education, the -- commerce and let's see. i can't. the third one, i can't, sorry. oops. >> two months later, rick perry dropped out of the 2012 presidential race. this year his second bid never caught fire.

hillary clinton had her own oops moment in 2008. >> what can you tell me about the man whose going to be mr. putin's successor? >> he's a hand picked successor? >> who will it be? >> whatever, yes. >> but her opponent proved not every awkward debate moment marks the end for a candidate. after this chilly exchange in 2008. >> i don't think i'm that bad. >> you're likable enough, hil hillary. >> stalling barack obama's momentum after his stunning win and a nomination fight. in the end obama turned it around, won the democratic primaries and went on to win the white house but few candidates managed to make it that far. sarah murray, cnn, washington. >> and "outfront" now michael

smerconish. funny when you see -- >> love that highlight reel. >> when president obama says to hillary clinton, you're likable enough but unforgettable moments. >> looks good on you. >> there is so much at steak tomorrow and part as you point out, there are a couple people never heard of. >> remember how high her numbers were before she formally declared? you see a declare and tumbling of the numbers and evaluated by a different spectrum. it will happen to vice president biden should he get into the race. his numbers i think will tumble, as well. here is what i keep coming back to her. her numbers tumble because she's taken fire but not from anybody, erin, on that stage tomorrow night. they have really gone soft on her. senator sanders has not wanted to engage in any negativity toward her. will it change tomorrow night? i don't think it changes with bernie sanders, maybe it does with martin o'malley and jim web. >> most americans do not know

who jim webb is. >> what does he have to lose? >> nothing. >> these issues we talk about, trust issues, e-mail issues, benghazi are now because of what we just saw with kevin mccarthy so associated republicans, i think you take a reel danger if all of a sudden you're one of her opponents and play that card because in front of these 1500 people you'll be perceived as the enemy. >> it's going to be fascinating. we'll see if one of those unknowns create the big moment of the night. thank you and we'll be right back. i have type 2 diabetes.

i started with pills. and now i take a long-acting insulin at night. i take mine in the morning. i was trying to eat right, stay active. but i wasn't reaching my a1c goal anymore. man: my doctor says diabetes changes over time. it gets harder to control blood sugar spikes after i eat and get to goal. my doctor added novolog® at mealtime for additional control. now i know. novolog® is a fast-acting, injectable insulin and it works together with my long-acting insulin. proven effective. the mealtime insulin doctors prescribe most. available in flexpen®. vo: novolog® is used to control high blood sugar in adults and children with diabetes. take novolog® as directed. eat a meal within 5 to 10 minutes after injection. check your blood sugar levels. do not take novolog® if your blood sugar is too low or you're allergic to any of its ingredients. tell your doctor about all medical conditions and medicines you take. ask your doctor about alcohol use, operating machinery, or driving.
