Just three minutes long. Thank you very much. I love you people. I loved you people. Reporter in iowa, the man who always brands himself a winner sounding like a gracious loser. Iowa, we love you. We thank you. Youre special. We will be back many, many times, in fact, i think i might come here and buy a farm, i love reporter but today on twitter, mount trump reerupting. Complaining about unfair reporting. Says, quote, because i was told i could not do well, i spent very little there. And finally, knocking the voters themselves, saying, i dont believe i have been given any credit by the voters for selffunding my campaign. Not worth it. Now, one of trumps old tweets back in focus. No one remembers who came in second. Today, cruz painting trump as a candidate coming unhinged who cant be trusted. Six weeks ago, donald trump was saying every day that i was his friend, that he loved me, that i was terrific, that i was nice. And now im aggravating. Reporter but its not just trump. Cruz will also have to get through senator rubio, who finished a surprisingly strong third. I think teds been very kag cue lated and will say or do reporter rubio sounding a lot like a firstterm senator who got a big boost from iowa. Heres rubio last night. So, this is the moment they said would never happen. Reporter heres barack obama in 2008. They said this day would never come. Reporter the president s former speechwriter tweeting that rubio could have at least thanked 0obama for the opening line. As rubio rises, his opponents on the attack. Governor Chris Christie calling him the boy in the bubble. You know who the boy in the bubble is up here, who never answers your questions, who is constantly scripted and controlled. Because he cant answer your questions. Its time for him to man up and step up and stop letting all his handlers write his speeches and halling him. Governor Chris Christie called you the boy in the bubble, suggesting that you are a very delegate candidate and you have not yet been tested. Chris has had a tough couple of days. Hes not doing very well. Sometimes when people run into adversity, they dont react well and they say things maybe New Hampshire. And tom, donald trump now reminding everyone, hes been spending his own money on this campaign. And trump adamant that a second victory. Reporter and david, thats because trump never cites a flaw and they ever sure roundnever surerenders ground. The Campaign Says they are much manufacture confident in New Hampshire. Trumps Campaign Manager has worked in this state in politics for years. He lives here. He knows the state inside and out. Second, they have much more elected leaders behind them in New Hampshire than they did in tom, thank you. And with seven days to go to New Hampshire, on the democratic side tonight, its official. Hill little clintary clinton won iowa. The closest result for the democrats in iowa ever. Hillary clinton in New Hampshire tonight, with former president bill clintonclinton, were both were campaigns. But can she do it again there . Bernie sanders leads in New Hampshire by doubledigits, in tonight, hes refusing to concede iowa. And youre about to hear why. Abcs cecilia vega from New Hampshire. Make no mistake. We are in a fight to the finish. Reporter tonight, Hillary Clinton and Bernie Sanders both on the ground in New Hampshire after both declaring victory in iowa. So, as i stand here tonight, breathing a big sigh of relief, thank you, iowa reporter Bernie Sanders standing proud, too. Refusing to concede. It looks like well have about half of the iowa delegates. Reporter the race so tight in some iowa precincts, it took a coin toss to break the tie. But today, Hillary Clinton making it clear. A win is a win. I can tell you, i ive won and ive lost there, its a lot better to win. Reporter today, i asked bill clinton about the photo finish. Im glad she was on the right side of it. I always thought it would be really close. Reporter a democratic socialist from vermont delivering a aerious blow to Hillary Clintons welloiled machine. Secretary clinton, is a virtual tie a win in iowa . Do you feel like a virtual tie is a win . It was a great win. Reporter it was a great win . Sanders landing in New Hampshire, enjoying a doubledigit lead in the polls. Feel the bern i cannot believe that you are here at 5 00 in the morning. Reporter today, feeling confident. And last night we began the Political Revolution not just in iowa, not just in New Hampshire but all over this country. Reporter but the clintons havs a history of New Hampshire comebacks. I listened to you, and in the process, i found my own voice. Reporter and now, Hillary Clinton is hoping for just one and cecilia vega reporting in tonight. We were on the plane from iowa to New Hampshire together. When we landed, the race was even closer between clinton and sanders. That didnt seem to stop Hillary Clinton from getting up on that stage first last night. Reporter it certainly didnt, david. She does not want to see a 2008 repeat like she saw in iowa, a devastating loss for her there. She is now here in New Hampshire, you can see this crowd here behind me. Shes about to start another event today. Even people in her inner circle, though, telling me, this is going to be a really tough race for her here, david. All right, cecilia vega working hard to get answers from both clintons today. Thank you. And one more note on the message voters are now sending. Who won when values were most important to voters . Who won on the economy . And who won as the outsider and will it now work in New Hampshire . Heres abcs jonathan karl. I loved you people. Reporter tonight, there are some real warning signs for donald trump. First, ted cruz has found a line of attack that stuck. Donald trump, new york values. Reporter more than 40 of iowa voters said values was their most important issue. Most of those voters went for cruz. Only 5 went for trump. So, the new york values attack yeah. Reporter worked. Here in iowa, New Hampshire, south carolina, nevada, everyone knows what new york values are. Reporter and why trump is a billionaire businessman, famously promised i will be the greatest jobs president that god ever created. Reporter Iowa Republicans actually thought marco rubio would do a better job with the economy. And they bought rubios argument that he has the best chance to get elected president. This land is your land reporter in iowa, Bernie Sanders showed Hillary Clinton has a big problem with young voters. A whopping 84 went for sanders. Just 14 for clinton. But part of clintons message worked with voters. I am proud of the progress weve made under president obama. Stand with president obama. President obama. Reporter clear majority of Iowa Democrats want to continue and the vast majority who care about electability voted for Hillary Clinton. And jon karl with us tonight from iowa. Still trying to get out with that blizzard. Jon, good luck with that. But in the meantime, i wanted to ask about the republicans. Lets go back to them. Donald trump, his ace in the hole still would appear to be his outsider status. He did very well with voters looking for someone from the outside. Reporter no question. And nearly half of the Iowa Republican caucus goers said they were looking for an outsider. 46 of them went for donald trump. Were going to see a lot of that going forward.
