24 delegates up for grabs here in New Hampshire. Weve been chasing the candidates across the state as they make their case to voters one last time. This morning we have interviews with Pete Buttigieg, Amy Klobuchar, joe biden, the Campaign Manager to for Bernie Sanders he will join us as well. John, is it too late for me to rethink our decision that youre inside a cozy area while im outside at this polling place . Because maybe for the next hour we will switch that up. But i am here at Northwest Elementary School in manchester, this is a very popular polling place, people are already trickling in, you might be able to see them lining up behind me. As for the candidates, they have been going after each other in this final stretch. They are also taking jabs at President Trump. The president was also here in New Hampshire last night, hes continuing his impeachment retaliation tour and while early bird voters are just arriving here to cast their ballots, the first votes have already been cast in three tiny townships just after midnight, you know this is the tradition where a little more than two dozen people voted up in Dixville Notch and places like that. There Amy Klobuchar is ahead, but the first vote cast went to a candidate who is not even on the ballot and that is Michael Bloomberg. So lets begin our coverage with cnns leyla santiago, she is also live at a polling precinct in port smith where Elizabeth Warren will visit this morning. Leyla, how does it look . Hey there, alisyn. As you mention, voting now under way, the primary in New Hampshire very much already running for the day and so the heat is on for these democratic president ial candidates that are looking to seal the first clear victory in this election season. I think weve got a path to victory for the democratic nomination. Reporter tension growing between senator Bernie Sanders and Pete Buttigieg, making their last appeals to primary voters. Buttigieg looking for support from those who may feel alienated by sanders progressive agenda. Im concerned that the idea that youve got to either be for a revolution or you must be for the status quo paints a picture where most of us cant see ourselves. Where most of us dont know where we fit in. Reporter sanders once again attacking buttigieg and joe biden for their rich backers. My friend mr. Buttigieg and my friend joe biden they have dozens and dozens of billionaires contributing to their campaign. We dont have any billionaires. Reporter after a poor showing in iowa biden looking ahead to contests in more diverse states. Im anxious to get to South Carolina, nevada. This is, you know, a package of four, just out of the gate, and i dont know how you can judge who is going to be a likely be able to win the nomination until you have the africanamerican vote and the latino vote and that doesnt come until a little later. Reporter biden isnt alone in needing a strong finish in New Hampshire. So as you probably heard, we are on a bit of a surge. Reporter Amy Klobuchar making a plea to voters still on the fence. I have always told people that if you are tired of the extremes in our politics and the noise and the nonsense, you have a home with me. Reporter Elizabeth Warren stressing democrats should reflect on how they failed in 2016. We cant have democrats firing at democrats or democrats mad at other democrats. We have got to pull together as a party because weve got to beat donald trump. Reporter President Trump was also here for a rally last night. So i hear a lot of republicans tomorrow will vote for the weakest candidate possible of the democrats. My only problem is im trying to figure out who is their weakest candidate. I think theyre all weak. And, you know, one of the things that struck me last night as i was talking to voters, how many of them were still undecided last night. I talked to seven voters, four of them were undecided, one woman telling me that she would likely make her decision after she stepped in that voting booth. John . No question, a lot of last second voters here in New Hampshire. Thats the way they do it here. Leyla santiago, thank you very much. Now, i caught up with former south bend mayor Pete Buttigieg on the trail, he told me his campaign its in a different place this morning than it was just a week ago because of his strong showing in iowa. He just visited, there he is right there, a polling place nearby where i am in manchester, New Hampshire. We are inside. Reporter the former mayor could not come inside here because all the voters are here. Pete buttigieg stopping by, getting out of his car, pausing, talking to a lot of the people as they headed into this polling place. Im at Webster School auditorium. There is already a sizable crowd here, people lining up to get their ballots to vote on this primary day. This place has only been open for just a few minutes and you can see by the number of people here a lot of them were actually able to see Pete Buttigieg before he came in here and take a couple of pictures with him. Shortly after he left we are anticipating in the 7 00 a. M. Eastern time hour that Amy Klobuchar will also stop by here to, you know, talk to some of these people before they come in, just to make one more stop, one more picture, try to convince people who may be on the fence that they will earn their vote in this first in the nation primary. These minutes and hours leading up to when these ballots are cast, the candidates throughout the day yesterday blanketing these states, all of them, holding rallies from early in the morning until late at night. I was at a couple of Amy Klobuchars events, the fire marshal had to close off these venues because so many people were showing up, so interest high this morning at least at this polling place, this school auditorium, this is already busy just minutes into voting starting. John, alisyn . It really is a remarkable image kind you, to see people lined up at 6 06 eastern time. They go right in to cast their votes before leg to work. Interesting to see the candidates outside. Ive talked to campaigns for years and they say there is no way to persuade any voter before they go in to vote on election day, but part of the reason why they do it is to keep the candidates busy or else he drive the Campaign Staff crazy. All right. Kyung lah here in manchester at a polling location i think will be busy all morning long. Coming up on new day, we have brandnew interviews with Pete Buttigieg, joe biden, senator Amy Klobuchar. I caught up with Pete Buttigieg yesterday on the trail and he talked, again, about whats different now for him, that he emerged from iowa as one of the front runners, he can feel the heat from the others. Kooung kyung lah. Here ya go, hon. Hello im an idaho potato farmer. Did you ever notice that the very first bite of every great meal is always the potato .

They are voting in the first in the nation primary. We saw moments ago Pete Buttigieg already out on the trial, theres pictures from him moments ago here in manchester, New Hampshire, meeting voters before they go in to cast their votes. He had a series of events that went late into the night. I caught up with him back stage at one of his campaign events. So when i last saw you it was before the iowa caucuses. Obviously a lot has changed since then, you emerged from there with a lot of momentum. How does it feel tonight . How different does it feel . Well, it feels really good, the energy were seeing among our volunteers, organizers and the voters showing up at our events tells me that we have momentum right now and are in a great position for a good night, but New Hampshire is a state that thinks for itself, voters dont like to be told what to do by other states or really anybody, and so we know that we need to earn every single vote, thats why weve been working so hard doing events across the state, making sure we speak to those voters who each now are still going through their options and making up their mind. How does it feel different than it did before . You know, every state has a kind of different feel to it. Here i think the fact that folks will go in and cast a ballot is just a different system from the caucus, of course, but the other thing is i think theres a greater than ever sense of urgency. As we speak donald trump is in this state, too, rallying his supporters and reminding us all why we need a new president. He has just rolled out a budget that will make savage cuts to education, environmental protection, he said Social Security even is on the table and medicaid is up for cuts. We know what would happen if this presidency continues and you can feel even more than before, i think that is correct voters are focused on the campaign that can go out there and beat donald trump. I think the candidates and the campaigns perhaps feel a little little more urgent also. One of the ways you can tell that is the way that you all talk about each other. I spoke with Simone Sanders, a Senior Advisor to the Biden Campaign and i asked her outright because joe biden has been talking about your experience and i asked Simone Sanders do you think that mayor Pete Buttigieg is really to serve as president on day one and she told me no. I respectfully disagree and so do a lot of voters. Look, at the end of the day this is about making sure that we bring the perspective that will be needed into the oval office. Im no stranger to holding off, im no stranger to government and im no vaiker to service both in uniform and in civilian roles. I know my way around washington and its not that i dont accept or dont understand the way that washington works, but we cant accept the division and the dysfunction that is going on and i think our best shot to change it and, by the way, our best shot to beat donald trump is a focus on the future. All right. That was Pete Buttigieg overnight. Moments ago he was visiting a polling location actually outdoors where you are looking at right now. You can see people in New Hampshire take this seriously. The doors opened at 6 00 a. M. In polling locations across the state, people were lined up ready for it, they are in there now to cast their ballots and we will point out, again, you can vote if you are a democrat, republican or in New Hampshire undeclared which means that if you dont register with a party you can walk in and vote in either primary and often those are the decisive voters in this state. Joining me now cnn Political Correspondent abby phillip and cnn political analyst alex burns, he is a national Political Correspondent for the New York Times and i should know Alisyn Camerota is standing outside with us at a polling location wearing a very warm jacket. And its snowing. More comfortable than shes letting on. Its snowing. I didnt get that part yet. Okay. In the snow. Were going to leave alisyn in the snow for a second, alex, and im going to ask you a question while she gets cold. What are the stakes . Anytime you head into a polling day on election day its important to think what the stakes are of this day. I think on the one hand its a big test of Bernie Sanders and whether he is going to be able to not just win the state but win it with the kind of vote share that would suggest to democrats across the country that he is emerging as a front runner in this race, right . That this is a state he dominated 2016, he has something of a Home Field Advantage here, i do think for Bernie Sanders theres obviously a big difference between first and second place, also very big difference between winning the state with 30 and winning the state with something closer to 40 . On the other side of the race on the moderate side of the race this is all about whether the moderates can get rid of joe biden, right . This has been the quest all along for every candidate in the race who is not a liberal populist, just can you get around this guy who is so well thrown and well liked in the party and as weve heard from mayor buttigieg and i think senator klobuchar as well there is this real sense there is an opportunity here to sort of sideline him going into some of the other states. Abby, it does feel as though the deck just keeps being reshuffled, here and elsewhere. So what are you watching for today . Its exactly that, alisyn. I do think that there is a chance here that, like alex said, one of the moderates could push joe biden lower and lower and lower in this race, which is really a danger zone for him. I mean, fourth place in iowa, i dont know that he can sustain another fourth place finish here in New Hampshire without it causing some Serious Problems for him going down the road. But i also think, you know, as were watching the top three slots, you have Pete Buttigieg right up there with Bernie Sanders. Is tonight going to be the time when he sees a late in the game surge . There has been a lot of energy for him here in the state. But Bernie Sanders did extremely well four years ago and has a lot of support in this state as well. And then beyond that, what happens to Elizabeth Warren . She came in third in iowa and i think her supporters believe she hasnt gotten enough attention for that, but part of the problem here is that there are only so many tickets out of these first two states and i do think that warren is in a position where she has to beat expectations, she cannot simply meet them in order to in order to have the momentum that shes going to need going further along in this race. So its going to be important to see, you know, particularly whether the race between sanders and buttigieg gets closer tonight than it has seemed in the polls weve been looking at over the last few days and whether one of the other candidates is able to edge out joe biden pushing him further down in his standing which i think could cause some Serious Problems for the race Going Forward for joe biden. Youre looking at live pictures, again, outside one of the polling locations here in manchester, New Hampshire. Supporters can stand outside there at a safe distance with signs, but you cant do much more than that. Its really a show of force there. Abby talked about the number of tickets out of New Hampshire. I read an article in the New York Times this morning which suggested there may not be a limit to the tickets out of New Hampshire, whereas normally in New Hampshire the field gets winnowed, it may not happen here. That article was written by alex burns. Explain. Big reveal. Look, the there are five candidates in this race who are seen as having a real shot at this thing
