Lucky. How he escaped with only a scratch. Fireball and on fire. The incredible streak still alive. The warriors nailbiting win. A doubleovertime victory. Throw it in. Big hoop dreams with their 28th straight. Setting their sights on that legendary record. Austin takes a 20second timeout. Were on, ron. Were on. Ron is asking, are we on . Hes been in television for several decades and doesnt know that when the red light is on. We are on. Vary fie it. Trust, but verify it. The red light is on. Lets do a show. A fascinating new dynamic shipping up in what has been to say least a lively republican race for president. Political theater at its finest. We havent seen much of this from donald trump. There is no podium. In iowa, fielding questions from the voters. It was there that he spent much of his time taking on the man who has now emerged as his numero uno contender in that key state. Were talking about ted cruz. The attacks not as over the top as we have seen in the past. Out to mary bruce this morning. Hi, mary. Reporter hi, paula. Good morning. It was a night of firsts here for donald trump. He held his first ever town hall here in des moines. And for the first time, took direct aim at ted cruz. What a nice job. Thank you. Reporter this morning, donald trump is soaring in the polls. And drawing new battle lines in the republican race. Its not a contest between the two of us just so we understand. Reporter jabbing ted cruz for the first time. Everything i say, he agrees with me. No matter what i say. I do like ted cruz, but not a lot of evangelicals come out of cuba. Oil pays him a lot of money. Hes got to be for oil, right . The Oil Companies give him a lot of money. So but im with you. Im with everybody. Reporter the texas senator is gaining on trump in iowa, where corn is king. If ted cruz is against ethanol, how does he win in iowa . Because thats very antiiowa. I dont know how he wins in iowa. I dont know. Reporter this farmer tells us, cruz wont cut it here. I think if anybody else gets elected, i think it will be a disaster. I dont think anybody else can do it but him. Reporter you think its trump or bust . Thats what i think. Reporter trump says hell take care of his chief rival. Will you name him your Vice President , or or hes a good guy. He is a good guy. I would say we would certainly have things in mind for ted. [ chanting ] reporter earlier, at a lunch in new york, trump took more heat for his call to ban muslims from coming into the u. S. All no trump, no kkk, no racist usa. Reporter a clear majority of americans oppose the idea. Likely primary Republican Voters are split. Right now, i have no problem with that. I like the idea. I wish he would focus more on problems with the immigration system in general. Reporter now, with 51 days until the iowa caucuses, trump promised hell spend a lot more time here. Joking everyone will be sick of him by then. In typical trump fashion, he says if he doesnt win here, this whole thing will have been a big waste of his time. Dan . That sounds like a trumpism. Mary, thank you. Lets get more from matt dowd who is joining us from austin, texas, this morning. Matt, good morning. Good morning, dan. So given the vigor with which trump has attacked his other rifles in the past, it seems to me like hes handling ted cruz with kid gloves. What gives here . I think its a couple of things. First, i dont underestimate Donald Trumps ability to slow ramp up to a high burn. So get prepared. I think hes already started this. It may get hotter later on. Two, theres a big overlap between trump voters and ted cruz voters. And so i think donald trump, who is very smart about politics, is aware of that. The third thing is ted cruz, though hes said a few things, has gone out of his way to bearhug donald trump. So i think donald trump is weighing the best way to draw the contrast. Republican Party Leaders appear to be very worried right now about the convention this summer. Usually, conventions are simply coronations for the nominee. Now theres talk that the republicans may be facing whats called a brokered or a contested convention. What does that mean . I think its better to call it a contested convention. The time of brokers are gone. What that means is no person gathers enough delegates before the convention is held to have a majority. And so thats i think the number is 1236 delegates. Nobody gets enough because of how the system works before mid march. I think there is some fear, and some expectation by some, that that may be the case. I think its a small chance. But its an increased chance that were going to see this. And that point is, dan, nobody knows what would happen in the midst of that if nobody goes into the convention with majority of the delegates. It would be history and a full employment act for guys like matt dowd. Thank you vmp. We would love it. We would love it. It would be an interesting week. No question about it. Matt, thank you.
