The polls and once again reset this game . As we look in on a polling precinct, this one in hudson, we can tell you officials have been predicting a record turnout. Lots of folks there this hour. As is tradion, voting began at midnight. And a handful of communities providing results so far. For the gop, trump, cruz, and kasich tied at the top with nine votes each. For the democrats, sanders leading clinton 17 votes to nine. Our team has been out with the candidates covering the finalal push. Katy tur is covering donald trump. [ cheers ] reporter as most of the other candidates crisscross the state to visit polling sites, donald trump was crisscrossing the airwaves. A heroin problem, drug problem. Were going to solve it. Were going to build a wall, stop it up. Last night, said whos going to play for the world going crazy, mexico, mexico. How much will the wall cost . Sure. Its probably 8 billion. Reporter the billionaire pitching himself and spinning criticizing ted cruz on water boarding. The showman sending a crowd into hysterics when he repeated a woman shouting from the flooror she said, i never expect to hear that from you agagn. She said, hes a [ bleep ]. Thats her. Her. Reporter New Hampshire is much more trumps style. Far less religious than iowa, its where trump can be trump. The billionaire is comfortable here. Hes led in 75 polls going back to june, relying on his broad message, big audiences, and brash insult. Jeb bush . Loser. Ted cruz . Ill say nasty. Hillary clinton . In a certain way, evil. Reporter his daughter trying to get out the vote. A lot of people coming out so far . Absolutely. Reporter nine month pregnant, she was playing ambassador for her dad. Ivanka trump. Reporter stopping at five polling stations and working the phone bank with volunteers. [ applause ] thank you. Down, trump is shaking hands and hoping his moment is now, not never. And donald trump has upended this race, hes broken all of the rules. If he wins hehe, it will be a big deal. Dare i say huge, especially considering hell be able to say that all of this enthusiasm were seeing does translate into votes, lester. All right, katy. Away from the boisterous rallies and his speeches brimming with confidence, i discovered a much more reflective donald trump when we sat down for an interview today. One who acknowledges the trump weve been seeing on the campaign trail is not exactlyly the one youd see in the white house. But i began by asking him if he believed the polls which have him leading here by double digits. No, i dont believe anything. I mean, i really want to see theres only one poll that counts, and that poll iss being taken today. Well see what happens. I think were doing well. We have great popularity. I go around, and everybody is liking what we did. We had an arena last night with 5,000 people. So well see what happens. I mean,ts going to be soon. Sound almost nervous about im tentative. You dont know. I mean, i have wonderful polls that are showing wonderful numbers. But as you know, lester, it doesnt mean that much. Although it is certainly an indication that youre doing okay. If you and Bernie Sander do well here, what does that say about the american electorate right no the mood of the country . Well, its very opposite. Although theyre very ch the same on trade. The difference is, he cant do anything about it. What a showing on what its showing on both sides is people are fed up with the people that are governing, with republicans, with democrats, the people governing. Theyve done a terrible job. And they look at him as an outsider, i guess, another word. They look at me as an outsider. And they look at me as somebody thats had Great Success and that can turn the country around. You have said a lot of shocking things on the road here. Im not going to go through them all. It no longer shocks us. Last night, you used a pretty someone in the crowd had said. And im wondering to myself, would you y that as president of the United States . No with the seal on the podium . Much different. Much different. Are you going to be a different guy as president than the one we see i went to the best school. His was a good student. I have an uncle that was one of the top professors at mit. Theres a good gene pool right there. I have to do what i have to do, right . Thats is that an act . No, its not an act. Last night we had thousands. It wasnt my word, it was a word a woman kept shshting. I only repeated the word. And the place was wild. It standing ovation, everybody that doesnt mean it was good. No, ill tell you what, when youre president or about to be president , you would act differently. Right now, im running against i started off with 17 people. Now were down to a smaller mber. Soon down to five probably. A lot of people. Question of acting, i want to be different. Youre being hit from 15 different sides. I wt to be different. When youre president , you act in a different way, no question about that. And i would do that. So the man we see behind the podium now in the campaign who pretty much says whatever comes to mind i dont say whatever comes to mind. In this case, it was like a retweet. It wasnt my word you said all lot of things that shock. Along the way. Thats fine. Any undecided voter in New Hampshire thinking i like him but some are saying i love him because hes not politically correct. It wasnt a particularly bad word, by the way. Some are s sing, i love him because hes not politically correct. Lester, people are so tired of people that are politically correct. Theres political correctness, but theres also plainold rude. I dont think it was rude. I got a standing ovation. It wasnt my word. I said the standing ovationon is for you. I got a standing ovation. Were having a good time. We have to have a little bit of a good time in life. Some of my conversation with donald trump earlier. If his numbers hold and he wins in New Hampshire, who will place second with that allimportant momentum . That could be the most suspenseful storyline coming out of t ts evening. The latest tracking poll shows marco rubio in a secondplace tie with ted cruz. It was taken partially after rubios muchcriticized performance in the last debate. And as nbcs Hallie Jackson tells us, other establishment candidates are seeing an opening. [ chanting ] reporter in New Hampshire, cheered by supporters and chased by robots, its marco rubio with the most to lose looking less certain to pull away from the establisent pack now. Were going to do really well. Were going to leave here with more delegates than we came in. Reporter his campaign had been hoping New Hampshire would win on the field. But stronger than expected showings fromhe governors could keep them in the race longer than expected. John kasich telling mee hes ready to trade snow boots for beyond. Do you have the money, do you have the organization there . Were going to be just fine. Well have the money and the organization, just like we always do. Sometimes we put it together with wire and duct tape, but we always seem to get it done. Reporter if jeb bush surprises with a topthree finish jeb reporter then he could be the comeback kid carrying momentum and resources into later states. Thats what this about. Its not being disrespectful to someone to point out that you have a better record. Reporter bush hoping undecided voters will show up for him like jeff wheeler did. And my initial gut reaction, thats the beltw happened. Reporter and Chris Christie polling in sing digits today pushing back against the idea New Hampshire is make or break for him. Well know it when we see it. We want to do really well, but i dont think anything is do or die tonight. How you doing . Repepter under the least pressure, ted cruz. More moderate New Hampshire, not en as a natural fit for the social conservative. I think a week a a lot of trump and rubio might be right at the very top. Well see what happens today. Reporter cruz already has a win under his belt in iowa. But for the rest of the candidates bunched up behind donald trump, what happens tonight could be all important. For them its a function of moving on to South Carolina. There could be little incentive for them to get out of the race unless theres obvious separation tonight. Lester . Thank you. Theres no shortage of drama on the democratic side w wre Bernie Sanders and Hillary Clinton are locked in a bruising contest that has turned increasingly ugly in recent days with poll numbers showing sanders possibly, possibly headed for a big victory in the state that famously made bill clinton the comeback kid. We get more from nbcs casey hunt. We love you, bernie reporter Bernie Sanders isnt used to being the frontrunner. Usually i like to take a nice, quiet walk. Apparently not today. Skipping the handshes and sticking to his quirky campaign style. Planning to meet voters, but instead meeting reporters on a walk around the block. I havent had a chancee to do much walking. Reporter are you still the underdog . Well, what i think is if there is a large voter turnout, a lot of folks come out to vote, were going do just fine. [ cheers ] reporter rival Hillary Clinton starting her day early, the oldfashioned way. Cardio. Reporter clinton had a doubledigit leadhis spring but went into primary day far behind sanders in polls. Were going to keep working literally until the last vote is cast and counted. And go from there. Reporter its a wrenching turn of events in a place where she bounced back with a win eight years ago. And in 1992, voters here resurrected bill clinton. New hampshire tonight has made bill clinton the comeback kid. Reporter this time Hillary Clinton hoping for a comeback in nextum nevada and South Carolina carolina, where shes hoping to turn out africanamerican voters. You have to face up to the hard truth of injustice and systemic racism. Reporter the question now, whether the Sanders Campaign is capable of going big. The Sanders Campaign is a small team. Are you ready to expand across the whole map . We actually have a big team. Its a grassroots campaign. We have a lot of pple on the ground, and we had them in iowa and New Hampshire. Were redeploying in the states. Reporter the sandede campaign is already planning to air tv ads in four super tuesday states. If this turns out to be a big night for him, expect the Clinton Campaign to escalate their attacks. Lester . All right, thank you. We want to bring in chuck todd and andrea mitchell. Chuck, you have seen some of the new exixi polling data. What are we learning . Reporter were learning that the d docratic electorate in particular looks like an electorate that Bernie Sanders should do well with. Let me start with the age gap here. This is something we tracked in iowa. Among voters under 30, Bernie Sanders, 86 to 13 for clinton. A majority. Thats not nearly a larar enough gap for her to be able to win if those numbers hold. Lets look at the issue makeup. Most important issues among democratic voters, it sounds like Bernie Sanders messaging. Income inequality, economy, health care third, terrorism a distant fourth. Now look on the republican side of the electorate top issues. The economy, one. Government spending, two, at 27 . Terrorism, National Security issues, three at 25 . This was a surprise to me, lester 15 picked immigration. Maybe not so hot if youre donald trump w w has made immigration such a big deal. Then of course theres time of decision. And this sometimes can tell us if there was momentum at the end or not. Among republicans, nearly half of the electorate told us they made their decision in the last few days. Thats good news for people with lastminute momentum like a john among democratic voters, more than half, 55 made their decision more than a month ago. Thats good news if youre Bernie Sanders. All right, chuck. Let me turn to andrea. If Bernie Sanders leads New Hampshire with aig victory, whats next for him and Hillary Clinton . Reporter if these trends hold up, this is going to be hell on wheels the next couple of weeks for Hillary Clinton. Bernie sanders has the money, he outraised her in january. He will come out of here if he has a big victory with more money that he will raise in february. She is eventually going to be hardpressed for money. Shes already outspending her on television ads. And now hes going to go right to the heart of her constituency. Hes going to leave here and im told go to harlem for breakfast and get a big endorsement from harry belafonte, trying to hurt her with the africanamerican vote shes cnting on in South Carolina. Lester . Okay, andrea mitchell. Thank you. Weve got more of the days other news ahead inclulung Customer Service calls that drive you nuts. A clever pair of brothers will slash your bills.
