Standoff between Pete Buttigieg and Amy Klobuchar that culminated with her asking if he was calling her dumb. And my question is what do they see that makes them think they need to run through cnns Arlette Saenz has the highlight of the debate. Reporter well, john, there were a lot of fireworks last night in las vegas. One candidate who benefitted from that was Elizabeth Warren. Her campaign saying she raised more than 2 million on debate day as she also won one metric. Speaking time. But all of these candidates came ready to fight last night in the most fiery and contentious debate yet. Is the democrats were ready to rumble against Michael Bloomberg. The fact of the matter is he has not managed his city very well when he was there. I dont think you look at donald trump and say we need someone richer in the white house. Reporter front runner Bernie Sanders delivering the first blow. In order to beat donald trump, were going to need the largest voter turnout in the history of the United States. Mr. Bloomberg had policies in new york city of stop and frisk. That is not a way youre going to grow voter turnout. Reporter bloomberg firing back at sanders throughout the night. I dont think theres any chance of the senator beating President Trump. Its a wonderful country we have. The best known socialist in the country happens to be a millionaire with three houses. Whatd i miss here . Reporter Elizabeth Warren was ready to strike zeroing in on the former new york city mayors alleged treatment of women. Id like to talk about what were running against. A billionaire who calls women fat broads and horse faced lesbians. And no, im not talking about donald trump. Im talking about mayor bloomberg. But understand this. Democrats take a huge risk if we just substitute one arrogant billionaire for another. Reporter fighting to keep her campaign alive, warren delivered attack after attack against bloomberg. He has gotten some number of women, dozens, who knows. To sign nondisclosure agreements both for Sexual Harassment and for gender discrimination in the workplace. So mr. Mayor, are you willing to release all of those women from those nondisclosure agreements so we can hear their side of the story . [ cheers and applause ] we have a very few nondisclosure agreements. Let me finish. How many is that . None of them accuse me of doing anything other than not liking a joke i told. They decided when they made an agreement they wanted to keep it quiet. They signed the agreements. Thats what were going to live with. This is also a question about electability. We are not going to beat donald trump with a man who has who knows how many nondisclosure agreements and the drip drip drip of stories of women saying they have been harassed and discriminated against. Reporter Pete Buttigieg made sure bloomberg wasnt the only candidate on stage with a target on his back. Most americans dont see where they fit if theyve got to choose between a socialist who thinks that capitalism is the root of all evil and a billionaire who thinks money ought to be the root of all power. Lets put forward somebody whos actual a democrat. Reporter and a mid western melee igniting when in a recent interview. I wish everyone was as perfect as you people. Yes, thats right. And i said that i made an error. I think having a president that maybe is humble and is able to admit that here and there maybe wouldnt be a bad thing. But youre staking your candidacy on your washington experience. Are you trying to say that im dumb or are you mocking me here, pete . I said i made an error. Reporter klobuchar trying to shift the focus back on the candidates real opponents. We have not been talking enough about donald trump and lets just talk about donald trump. Reporter now, the nefss caucuses are just two days away as these candidates are making their closing pitch to voters here. And tonight there are two more cnn president ial town halls on the stage right behind me with joe biden and Elizabeth Warren. All right. Arlette saenz for us in nevada for us.

Former new york city mayor Michael Bloomberg made his debut on the debate stage last night. And he was greeted by an onslaught of bruising attacks most pointedly by senator Elizabeth Warren. He has gotten some number of women, dozens, who knows . To sign nondisclosure agreements. So mr. Mayor, are you willing to release all of those women from those nondisclosure agreements so we can hear their side of the story . None of them accused me of doing anything other than maybe they didnt like the joke i told. And let me just there was more, but here we are. Lets bring in david gregory, cnn political analyst. Bakari sellers. And the author of the forthcoming book the populists guide to 2020. Krystal, ill begin with you. How do you think that bloomberg, his much anticipated debut went . It was an utter and complete disaster. And im sure that he realized halfway through he should have just stayed home. He was doing better just buying paid media. Rather than having to actually respond to attacks. What is the pitch Mike Bloomberg is making . Hes making the electability pitch. Im the guy whether you love me or not, i am the guy who can defeat donald trump. And last night on that stage, he looked like absolutely anything but that. And that is the major issue for him. And you have to think john, you were pointing this out earlier. Bernie sanders came into last night the front runner. The only candidate who really could even rival him in terms of ultimately winning the nomination seemed to be Michael Bloomberg. And that took a massive hit last night. So the question i have is that some of these questions you could see coming from a million miles away. There are questions you see the day you enter the race for a guy like Michael Bloomberg has to do with stop and frisk and also with the Sexual Harassment claims against his company. But this is his answer on stop and frisk, the policing policies when he was in new york city. Listen to this. Ive sat, ive apologized, ive asked for forgiveness. But the bottom line is we stopped too many people, but the policy we stopped too many people and weve got to make sure we do something about criminal justice in this country. There is no great answer to a lot of these problems. And if we took off everybody that was wrong off this panel, everybody that was wrong on criminal justice at some time in their careers, thered be nobody else up here. Two questions. Number one, what does it tell you he wasnt ready for a better answer to that question . And two, the bigger issue with bloomberg this morning is there are people out there who were curious. You said this. There were a lot of voters that have seen the ads. There were a lot of voters who want to beat donald trump and are bloom curious about whether bloomberg is the guy to do it. So how much of an impact will that performance last night have on all this . I mean, look. The performance was god awful. It was one of the worst performances. I dont know what my level of expectation was for Michael Bloomberg, but he didnt meet that. Its amazing to someone who has billions of dollars and all of these resources not spend any money on debate prep. If he did, he probably fired them all before the plane left las vegas. So it was a deplorable performance. I think that as i said earlier, those curious individuals and krystal was right. That for many people, the only person who could rival Bernie Sanders as his field is winnowing and were getting to nevada, South Carolina, and then the big debate hall or the big delegate hall of super tuesday. People thought it was going to be Michael Bloomberg. After last nights performance, im sure bloomberg wishes he never showed up. People are used to big losses at the craps table. But its very rare you see somebody take a loss like that on a debate stage. And i think the two people who will benefit from that are Elizabeth Warren and more so joe biden. Again, you started to see joe bidens lead with africanamericans get cut some by Michael Bloomberg. And that was because of the ads they saw that portrayed him as taking on donald trump. Donald trump will destroy Michael Bloomberg if last night is what happens. By everybody else on stage last night, he just didnt prove himself to be a good candidate. I dont think thats going to change next week in South Carolina on the debate stages. Because i just cant harp on how disappointing that performance was by the mayor. Well, his campaign claims it is going to change. Heres what they said, david. Quote, it took mike just three months to build a Stronger Campaign than the rest of the field has built in more than a year. It took him just 45 minutes in his first debate in 10 years to get his legs on the stage. He was just warming up tonight. We fully expect mike will continue to build on tonights performance when he appears on the stage in South Carolina next tuesday. Your thoughts . Well, i think the problem is its too late in the game to have a really bad first impression. You know, youre blanketing the airwaves, hundreds of millions of dollars youre spending on putting ads throughout the super tuesday states. Then you completely underwhelm and bomb in your first debate. Im sympathetic to the idea hell up against other candidates who have been doing this for as he said two years in preparation and theyve already had eight debates. And i dont think hes going to get that kind of room. And the biggest thing is why do you want to be president . Whats your narrative . Whats your rationale . He certainly didnt seem ready for the number one defensive question around stop and frisk. I can in 20 seconds come up with a better answer for what he was trying to do, the fact that he sought amends, that he has support from africanamerican leaders, and what that support is built on for him to try to make that case. But i will say the other winner in all of this and i think krystal alluded to it is Bernie Sanders. It was striking to me how threatening all of the candidates found Michael Bloomberg that they failed to really try to knock down Bernie Sanders. Even in Elizabeth Warrens terrific performance and certainly got a lot of support from her supporters. Bernie sanders is still the primary impediment to her moving forward and she didnt really take him on. I thought that was true across the board. To that point and i think david raises a great question about that. Bernie sanders came in the front runn runner. He probably left the front runner as well. Elizabeth warren had a debate performance that a lot of people said was terrific. What does she see as her path . I really want an answer. Im curious. Im trying to figure out what shes doing now that she thinks will help her win the nomination. Does it go through sanders supporters . Is it the other perceived lane right now . Yeah. I think its very tough for her at this point. And she did have a phenomenal debate performance last night. I think she did herself a lot of favors. A lot of folks have already voted in nevada, but i would certainly expect her to improve. Especially with that White College educated voter. And that gets to your question. Look, she and pete and amy primarily have been competing for that sort of white affluent liberal vote which is the vote that has shifted around the most, right . They were with pete. They were with amy. Now i bet they would give Elizabeth Warren a look. Thats enough to give you a bump in the polls. It is not enough ultimately to get you the nomination. I think thats the issue for her. Bernie sanders has largely consolidated the progressive lane. Fing youre her campaign, she thinks amy had a moment. She was able to get the comeback narrative. If warren could grab a second in nevada and hang on best she can in South Carolina and head into super tuesday where california has been a relatively decent state for her, maybe she can make a case. Maybe the most important answer of the night is when all of the candidates got asked what they would do if there was one candidate who had a plurality but not a majority of the delegates going to the convention. And every single candidate including Elizabeth Warren and except for Bernie Sanders said they would let the Convention Rules play out meaning that they want the superdelegates to try to get involved on their behalf. And if we come down to a contested convention where Bernie Sanders gets a plurality of the delegates but not a majority, that means things could get very ugly. Bakari, we have to let you go because we have hang on, david. Baka bakari who helped write the rules on the dnc conventions that Bernie Sanders might be upset about at convention time. I think thats hilarious. Yeah. Bernie sanders helped write the dnc rules that Bernie Sanders now doesnt want to help follow. The rules are the rules. You cant get in and then say i dont want to play by those rules. I do think, though, you know, that the party has a not a decision to make, but has to understand that it will be messy. And i think when you get to a convention if it is contested and Bernie Sanders has a plurality by a large mahrgin, hes going to be the nominee. If it comes in and its close, i dont know what will happen. You just have to understand that its a bit of hypocrisy when you write the rules then all of a sudden dont want to play by them. I know bakari is going. David gregory, youre first up after this quick break. Okay. So there was also a bit of fight last night between klobuchar and buttigieg. What did they get out of that . And what about joe biden . We discuss that next.

Extremely tense moments between mayor Pete Buttigieg and senator Amy Klobuchar is last nights debate. Watch this. Youre literally in part of the committee thats overseeing these things. And were not able to speak to literally the first thing to the politics of the crisis. Are you trying to say that im dumb or are you mocking me here, pete . Been unusual among democrats, i think the democrat among all of the senators running for president most likely to vote for Donald Trumps judges who we know are especially hostile to dreamers and to the rights of immigrants. I wish everyone was as perfect as you, pete. You know what . You have not been in the arena doing that work. Youve memorized a bunch of talking po
