Full coverage of super bowl sunday coming up. Well start with the republican debate, which aired right here on abc overnight. Plenty of fireworks. Perhaps serious consequences for some of the candidates with the New Hampshire primary just two days away. We have team coverage. Well start with jon karl right there in the debate hall. Hi, jon. Reporter good morning, paula. It was a raucous night. It was a good night for the three governors on the stage. They had been stuck on the back of the pack. Do or die debate for all of them. Back at center stage, donald trump responded to questions has the temperament to be the commander in chief. I actually think i have the best temperament. Im not the one with the quick trigger. Other people up here would be week trump was so intemperate he might nuke denmark. Asked about that, he backed off. Do you stand by those words . I think that is an assessment the voters are going to make. If you noticed, he didnt answer your question. Reporter cruz apologized to ben carson, after his campaign wrongly claimed that the doctor was going drop out right before the iowa caucuses. When this transpired, aamoll jazzed to him then. And i do so now. Ben, im sorry. We can see what happened. Everybody can see what happened. You can make your own judgment. Dr. Carson, thank you. Reporter the biggest target of the night was marco rubio. He ran into a buzz saw named Chris Christie. You have not been involved in a consequential decision where you had to be held accountable. You just simply havent. I think the experience is not just what you did but how it worked out. This country already has a debt problem. We dont need to election someone that has experience of running up and destroying the Credit Rating of a state. United states, the memorized 30second speech doesnt solve one problem. And when the worst Natural Disaster in your States History hits you, they expect you to rebuild their state. Thats what ive done. None of that happens on the floor of the United States senate. Its a fine job. Im glad you ran for it. But it doesnt prepare you for president of the United States. Reporter perhaps the real story of the night was the governors, christie, kasich, and bush. Dominated much of the debate. We have to solve problems in america by coming together, republicans and democrats. Americans first. Party and ideology second in the second backseat of this country. Thats what we need to do. Reporter jeb bush went after trump on the issue of imminent domain. Until trump shushed him. Let me talk. Quiet. A lot of times a lot of times [ crowd booing ] reporter trump backing in the boos did something never seen before in a president ial debate. He attacked the audience. Thats all of his donors and special interests out there. [ crowd booing ] that before. A candidate on the stage attacking the debate audience. With just two days to go until the New Hampshire primary, the candidates are hitting the trail hard. I count 15 events today, thats all before the super bowl. And how many times have you said i have never seen that before on the campaign trail in season . Too many to count. Its been the theme of this campaign. Thank you, jon. It was uncomfortable at times for marco rubio. He had all the momentum going into the debate. The other candidates did everything they could to derail him. David wright joins us from the debate hall with much more. Hi, david. Reporter hi, paula. This was a lost opportunity at best for marco rubio after a strong showing in iowa. His big moment to shine. Many would say that he choked. It all started with david muirs first question to Chris Christie. I do want to ask governor christie. You said fool me once, shame on when it comes to electing a firstterm senator. Reporter after that, governor Chris Christie came out swinging hard after marco rubio. First, lets remember something, every morning when a United States senator gets up, they think about what kind of speech can they give. Every morning when i get up, i think what kind of problem do i need to solve for the people who actually e likted me . Reporter shot after shot. Thats not leadership, thats truancy. Reporter christie pummeled rubio for more than seven straight minutes. Wait a second. Is that one of the skills you get as a United States senator esp also . Because i dont think it is. Reporter rubio punched back. Chris chris, your state got hit by a massive snowstorm two weeks ago. You didnt want to go back. They had to shame you into going back. Reporter thats when rubio got tangled up in his talking points. Lets dispel this fiction that barack obama doesnt know what hes doing. Reporter christie caught rubio putting that line on instant replay. This notion that barack obama just not true. The memorized 25second speech. There it is, everybody. Reporter even rubios fellow floridian seemed to jump in on governor Chris Christies side. You learn this. You learn this by doing it. Not to say. Lets be clear, marco rubio is a gifted, gifted politician. Reporter rubio, clearly rocked by the blows, moved on. Jumping back in with ted cruz after martha asked about attacking north korean missiles before they launch. Its standard procedure for the United States to shoot town those missiles once launched if they pose a danger to civilians im talking about a preemptive strike on the launch pad. But its important to note. That it is and senator cruz, i think, was alluding to this as well. Reporter should i go now . This is where one of the other big moments happened. Dr. Ben carson missing his entrance cue. As the other candidates kind of awkwardly went around him. Donald trump kept him company for a little while. Apparently, it was very hard for them to hear with all of the applause. David and martha were facing this way. They didnt see what was going on. In the end, governor Chris Christie offered to introduce governor kasich. It was a comedy of errors, shall we say. David, its always your big moment. I think its fair to say that all of us who have worked in Live Television have had moments. As a reminder, its live, folks, anything can happen. Anything can happen. David wright, thank you for your reporting. We appreciate it. Lets do some sunday morning quarterbacking with matt dowd, also in the debate hall there in manchester. Matt, good morning. Lets start with rubio. Was he seriously damaged by what happened on stage last night . Since were going to stay with the football analogies, i think what happened last night to marco rubio was that the young quarterback who had completed a bunch of passes got sacked by the experienced linemen. Now the question is, does he have a knee injury, an arm injury, or is he out of the things. First, it takes away any momentum that he had coming out of iowa and into New Hampshire. Thats for sure. Hes lost the momentum. Can he still finish second . I think he can. The other thing more importantly is, is this now, is this criticism now in the water table . It was something a lot of people thought about. Is he ready . Is he experienced . Is he just a great speech or is there more to him . Thats the thing that could be a bigger problem for him in the long term. Can he recover . Chris christie went hard at him. I think we were all reminded that Chris Christie is a former federal prosecutor. Does that help christie or perhaps somebody else on the stage . I think it might help christie a little bit. Right now, here in New Hampshire, hes at six or seven in the polls in the single digits. Even if he gets a bump of two or three, it wont help much. I think it could help others on marco rubios momentum rise. Now that was stopped by Chris Christie. Lets talk about the guy leading in the polls, donald trump. Do you think he did anything that will impact his front runner status . In particulala what jon karl said he had never seen before, particularly a candidate attacking members of the audience . Well, first, i think hell benefit from that. A lot of people say, yeah, the contributors. Big special interests. Donald trump took them on in the audience. I think donald trump, i wouldnt say he won the debate. I would say he won the night. He walked in here with a doubledigit lead. He comes out with a doubledigit lead. The main person that was competing to beat him in New Hampshire, marco rubios momentum was stopped. I think donald trump is probably very happy about the night last night. So there are eight gop candidates right now. The governors, kasich, bush, and christie had a strong night. Especially christie. Seemed to push all his chips on the table. Do you have a sense that if they any of them will drop out . I would guess that theres three governors still competing in this race. Two of them or maybe one of them are only going to go on from here. I think youll see one or two of the governors after tuesday seriously consider and drop out. They may take a little while. I think youll only see one, at most two governors come out of New Hampshire tuesday night. So high these stakes. Matt dowd, we always love have youg on and getting your analysis. We appreciate it. Lets not forget the democrats. Hillary clinton and Bernie Sanders locked in a fight. Sanders Getting National tv exposure on saturday night live and Hillary Clinton livetweeting. Cecilia vega has the story. Shes also in New Hampshire this morning. Good morning to you. Reporter hey, dan, good morning to you. The two sides duking it out for votes here in New Hampshire. A fight to the finish. But they also went head to head for laughs last night. Hillary clinton on twitter. And then there was bernie will the real Bernie Sanders please stand up . Wait a second [ cheers and applause ] i am so sick of the 1 getting this preferential treatment. Reporter sanders and comedian larry david side by side on snl overnight. Sounds like socialism to me. Democratic socialism. Whats the difference . Huge difference. Reporter david showing off his bernie best. People love me, okay. I have more individual donations than any candidate in history. And i dont take from millionaires and billionaires. I feel like a rock n roll star. Reporter earlier in the day, sanders rallying supporters in New Hampshire. We went to iowa, 40 or 50 points down in the polls. We end up getting a virtual tie. Reporter and Hillary Clinton trying hard to close the gap. Going door to door in the granite state. A Beautiful Day in manchester. Doubledigits here, clinton now laying it all on the line. Theres a much greater burden on women running for political office. There is still a huge double standard. Reporter clinton under fire in last nights republican debate. Im the last person she wants to run against. Reporter she fired right back on twitter with this reaction, saying, bring it on. Sanders jumping in the fray, too, tweeting this head shake saying, not good enough. And as you said, clinton down in the polls in New Hampshire. She leaves the state and heads to flint, michigan, where theyre dealing with the water crisis. Here in her place, her not so secret secret weapon, bill clinton. Bill clinton. Cecilia, thank you for your reporting this morning. And we should mention, fresh off the debate, abc news chief anchor George Stephanopoulos has a huge show coming up. Hes going to be speaking with senator marco rubio, donald special edition of this week and north korea was a topic of debate. Longrange rocket. This morning, the United NationsSecurity Council will hold a meeting. There are fears this could be part of a banned test that could make north korea capable of directing a Nuclear Missile at the United States. Now, the north korean government is responding by saying what they launched is an earth observation satellite as part of what they call a peaceful space program. Just last month, they claimed to have successfully tested a hydrogen bomb. Meanwhile, here at home, massive security in advance of super bowl 50. Bomb detection experts. Undercover agents. S. W. A.
