Ted cruz won three and marco rubio got his first victory of the campaign in minnesota. That gives trump 234 more delegates compared to 199 for cruz and 88 for rubio. Clinton now has more than 40 of the delegates she needs for the democratic nomination. Crown. Our Political Team is ready with the results. We begin with Major Garrett in palm beach, florida, showing us how the Trump Victory has shaken the Republican Leadership. Reporter if this was a typical president ial Campaign Donald trump and his party would be moving together toward the convention. But some forces in the gop want to block his path to the nomination. Its a split without precedent in modern politics with a resolution no one can precinct. It looks like we could win six or seven or eight or nine. Reporter donald trump used the ballroom at his resort as a president ial backdrop to celebrate his super tuesday romp. This isnt like its a close match. Its only too bad that winner didnt take all. Because if winner took all, this thing is over. Reporter trump did not repeat claims that ted cruz was instead complimenting his two victories and long before marco secured his first and only victory of the campaign in minnesota, trump declared him the nights big loser. He hasnt won anything and hes not going to win very much but i congratulate ted because i texas. Reporter cruz won in texas in and neighboring oklahoma and declared trump unfit for the presidency. America shouldnt have a president whose words would make you embarrassed if your children repeated them. Reporter cruz also had this message for rubio, john kasich and ben carson. For the candidates who have not yet won a state, who have not racked up significant delegates, i ask you to prayerfully consider our coming together. We have real problems. Reporter rubio remained combative and argued his harsh new attack slowed trumps momentum. Explain to the American People that donald trump is a con artist. Reporter rubio told cbs news the gop would never rally around trump. Trump at times sounded conciliatory like a candidate comprehending the burden of leading a divided party into a general election. I think were going to be more inclusive. I think were going to be more unified and i think were going to be a much bigger party, and i think were going to win in november. Reporter surveys of voters in six states show that 90 of trumps supporters were looking for an outsider. 60 saying they were angry with the federal government. In two weeks they square off in florida. Rubio trails trump by double digits. Hillary clinton beat Bernie Sanders in seven of 11 states with the overwhelming support of black voters, older democrats nancy cordes is in miami where clinton celebrated last nights victories. Good morning. Reporter good morning. Clinton cleaned up last night, winning a couple hundred more delegates than Bernie Sanders. She did it by winning some of the largest states and winning by landslide proportions, putting her nearly halfway to the nomination. Thank you all so much. What a super tuesday reporter how super was it . She won six Southern States by 30 to 60 points, including delegaterich texas. She pulled off an upset in massachusetts and began to position herself as the antitrump. We know weve got work to do, but that work that work is not to make America Great again. America never stopped being great. [ cheers and applause ] oklahoma, colorado, minnesota plus his home state of vermont. He said he would soldier on even if the delegate map it daunting. 15 states will have voted. 35 states remain. Reporter cbs news exit polls show clinton outperformed with and women. I believe what we need in America Today is more love and kindness. [ cheers and applause ] reporter sanders won among white men and voters under 30. I know that secretary clinton and many of the establishment thinking too big. I dont think so. Reporter clinton is now one step closer to making history as the first woman to head a party. A thrill for supporters who watched her frontrunner status she cares about women. She cares did uniting us. I think a woman gets things done. Her place is rightfully in the white house. Reporter clinton chose to celebrate her wins in florida because the states primary is coming up and the state is always a key Battle Ground in the general elections. If she is going to be going up against donald trump, she needs to start laying the groundwork now because, norah, as you know he is practically a local. And keeps a small residence called maralago. The possibility of a trumpclinton contest is a huge concern for Republican Leaders. One recent poll shows clinton with an 8point lead over trump in a general election matchup. Ted cruz told us last night that he should be the gop candidate, even though Party Leaders have a problem with him. Here is perceived reality. The republican establishment does not like you that much. I think thats fair to say. And you need them to beat donald trump. Well, we need to unify the Republican Party, and all of this primary is about winnowing it down. Senator Lindsey Graham, who has made it he is not a fan of cruz says the texas senator may be the only gop option at this point. But graham told us last night it may be too late. You seem to be suggesting at the convention or before the convention to stop donald trump from being the nominee. Short of a major scandal, probably not, if marco doesnt win florida, i dont know how he ted cruz. We may be in a position where rallying around ted cruz is the only way to stop donald trump. Im not so sure that would work. Youd recommend that in order i cant believe i would say yes, but yes. Cbs news and face the nation moderator John Dickerson is here and peggy noonan. Rubio wins florida, kasich wins ohio and they keep winning down the line to keep trump from getting to 1,237 delegates. If he falls short the republicans all go to the convention and have a big fight about who will be the nominee. Peggy we were talking about it last night and you said you were watching the Republican Party shatter before our eyes. But trump did well with moderates in the north and well evangelicals in the south. Turnout reached in certain areas historic levels. Look, we are in an amazing point where the leading nominee for a party for the partys nomination moved forward decisively, is seen by all as the frontrunner. If he were not donald trump, would be celebrated as the frontrunner. And what did it do last night . It started a civil war in the party. It had been building for a few days, but last night, certainly on this air, we really saw it. Marco rubio said, trump gets the nomination it will destroy the Republican Party, it will split it. This is serious stuff and uncharted territory. Is there anything that trump could do to heal the breach . You know, there were things along the way that he could have done. Whatever else it was, it was a mistake when he did this david duke, kkk, stuff. That really, i suspect, blunted his progress in places Like Northern virginia. What can he do . Oh. You know, he tries to make steps forward. Last night he was serious and sober and adult and president ial, sort of, in his big acceptance speech. And then at the end he got a little tough about paul ryan because he cant help himself. I dont know what he does. It was a little weird to hear him threaten the speaker of the house. A little weird is one way to put it. A lot weird. I guess do you think there will be establishment folks who come in and start supporting trump . Will we see more of the Chris Christies say that theyre willing to go . As peggy mentioned, the difference now is people were moving to acceptance, starting to get on order. To condemn the kkk and White Supremacists it put republicans in the position where they said, wait a minute, hes the person who be defining our party. Our candidates in tough races will have to answer for every unpredictable thing he did. Unpredictability. When you get into the november races republicans will be on their own and clashing with their nominee. It was the threat to the future of republican officeholders that also made them pause. Digging into the exit polls last night, we did see that late deciders did break for marco rubio and ted cruz. Does it suggest that things may be turning as we look to the big states on march 5th, 8th and 15th . They look at virginia where he was up by double digits. And then these attack happened. Rubio. That is the potential template. But there are also a whole lot of people who are voting for donald trump. You cant for the scenario where he gets stopped at the are going to him, all the energy thats going to him has to just stop. Voters count. Yeah. Yeah. They count. One of the things thats turning them out is the idea that the establishment can rush in and go do something. Every time they try to stop him they create more energy to propel him.
