And abcs tom llamas, leading us off now from florida. Reporter tonight, donald trump with a new message. Predicting hell get a knockout. Delegates . I think so, yeah. I really think so. I dont see the Convention Going that route. I see i see probably getting the delegates. You know, its like the fighters. Thats the ultimate way of doing it. You knock them out. If you knock them out, nothing can happen. You want to go for a knockout. Id rather go for a knockout, yes. Reporter trump talking like a brawler late today, just hours after promising his leadership style would be one of the most president ial ever. I would say more president ial and ive said this a couple of times, more president ial than anybody other than the great abe lincoln. He was very president ial. Right . Reporter at the Country Club News conference, trump surrounded by some of his signature products including even raw meat. We have trump steaks. And, by the way, if you want to take one, well charge you about, what, 50 bucks a steak . No, i wont. Reporter problem is, trump steaks have actually been discontinued. The meat on that table from another supplier. But in that room, the gop frontrunner was really selling Something Else. The idea of trump the uniter. I say, lets come together, folks. Were going to win. I say lets come together. Reporter today, as trumps lead grows, the antitrump movement pushing forward. The next president of the united states. Reporter former candidate carly fiorina, now endorsing senator ted cruz. Trump once attacking fiorinas appearance, saying look at that face. Would anyone vote for that . I think women all over this country heard very clearly what mr. Trump said. I think shes got a beautiful face and i think shes a beautiful woman. Reporter fiorina once had tough words for cruz, too. Ted cruz is just like any other politician. He says one thing in manhattan, say to get elected and then hes going to do as he pleases. Reporter but she now pleases hes the one to stop trump. Still in the game, Ohio Governor john kasich, and florida senator marco rubio. Both banking on home state wins next tuesday. I believe with all my heart that the winner of the florida primary next tuesday will be the nominee of the republican party. And tom llamas live in florida tonight. Tom, marco rubio with a miserable night. Iserable night. I asked him last week, regret going personal with donald trump and he told me that trump deserved a taste of his own medicine. But tonight, rubio is saying Something Else . Reporter thats right, david. He said, when he launched those attacks, the media was covering all his speeches, but thats not what it takes to be president. Today, saying that his own kids were embarrassed when he went down that road and if he had the choice again, he would not do it. David . All right, tom llamas. Thank you.

I just want to take this opportunity to thank the people of michigan. Reporter but the win now political armor. Sanders cutting into what had been her firewall, africanamerican voters in the south. In michigan, she won by just a two to one margin, and the young black vote, nearly split. We caught up with sanders today during a break from his debate prep. Why did she lose michigan . Whatd she not do right . Because we got more votes than she did. And i think it comes down largely to trade issues. I have understood from day one that these trade agreements, nafta, permanent normal trade relations with china, were a disaster for american workers. She supported them. Reporter but heres the math. Clintons delegate lead so strong that in all five states, voting on tuesday, she could lose by double digits and still win the nomination. Sanders would have to win everything left by double digits. So, do i think we can win states by double digits . Yeah, i do. Cecilia live from florida tonight. And Hillary Clinton ahead in the polls in michigan. The stunning defeat last night. Telling you, how does the campaign explain the loss, cecilia . Reporter well, david, they concede that the Sanders Campaign spent a lot of money in michigan, and that he campaigned very hard there.
