History, ted cruz boasted he defied the odds. Every tv pundit on virtually every station said cruz cant win, no chance cruz is going to win iowa, not going to happen. It would be trump, trump. Trump. Reporter but it wasnt. Trump fellll,000 votes short andnd gave an uncommonly subdued concession speech. We finished second. I want to till you something, i am just honored. Really honored. Today the bombast was back. Trump complained on twitter he the vors for self funding his campaign and the media has not covered my long shot great finish in iowa fairly. Trump called cruzs victory speech, long, rambling and overly flamboyant. The race is quickly becoming a battle among, trump, cruz and marco rubio. The florida senator says he is who is closer now . I t tnk i am. We are one delegate apart. Second i give us the best chance to unify the party. You cant win if the party is divided but to grow it. Reporter rubios momentum comes with attacks from kasich, bush, and christie who need strong showings in New Hampshire see if he will answer your questions, stand up and take that. I dont thininhe will or can. What do you think that its about . Sometimes when people are under duress they react in ways they will regret later on. Christie finished 10th. Cruz worked hard for his victory in iowa. Holding 2 3 as many events as trump, a third more than rubio. Do the math, trump collected twice as many votes per iowa visit as cruz. Worth remembering, Iowa Republicans havent picked the nominee since 2000. Major garrett for us tonight. Thank you. Here is nancy cordes. I am so thrilled that i am coming to New Hampshire after winning iowa reporter the first woman ever to win the Iowa Caucuses diit by. 2 . Senator sanders a a you conceding the race in iowa. Last i saw we were four delegates down. As the i understand it, there was some precincts where delegates were one with the flip of the coin. We want to take a, a l lk at that. At least six precincts broke a tie with a coin toss. Hillary clinton. The largegeurnout, evenly split, caused challenges elsewhere too. Well should a realignment. In the end, 84 of young ters, under the age e 30, went for sanders. But 58 of caucus goers were 50 and up. And they went overwhelmingly for clinton. Territory for clinton. The latest cbs news Battleground Tracker shows sanders leading in New Hampshire by 19 points. His democratic socialist message plays well with the states large independent population. It sounds to me like u are ready for a political revolution. Reporter sanders also has something of a Home Field Advantage here. He is from neighghring vermont. Clinton has the deep ties here too, scott, it is here she staged a come back eight years ago after a stinging loss in iowa. Nancy cordes, thank you. Two casualties of the Iowa Caucuses, republican Mike Huckabee who won there eight years ago. He did poorly last nig and dropped out. So did democrat martin omalley. Clinton picked up 22 National Convention delegates in iowa. Sanders, 21. But thats a little misleading because clinton already has 362 superdelegates. Party leaders who pledged their that brings her now to 384 or about 16 of the 2,382 she needs. After New Hampshire, the polls indicate the primaries are expected to break clintons way. On the republican side, cruz picked up eieit delegates, trump, rubio, seven. They need a little over 1,200. So, far to go. John dickerson, our cbs news political director and anchor of face the nation. John, we heard what a difference an election makes. Tell me how has the race changed . Whats the new framework . We have been talking about the race in terms of establishment, versus the ououider. We shoe look, ideology, versus electability. Look at entrance polls in iowa, who shares your val use . En they were asked who do you think can win in november, the large share went to marco rubio. Going into New Hampshire, ted cruz is saying im the true consistent conservative. The keeper of the flame. Rally to my light. Marco rubio is saying i can beat hillary clinton. Tell me where does this go from here . Well, marco rubio did well in iowa in part because he did better than expectations. But now he is saying he is in the top tier, he is the alternative to cruz and trump. Those expectations are very high. So, he would have to do very well in New Hampshire which is a less ideological state. Of course he has new competitors there in bush, christie, and kasich. All of whom want to drag him down. Of course there its the roiling fight between ted cruz and donald trump. John dickerson. Watching on sunday on face the nation. John, thank you so much.
