Hes attacking the front runner by a lot. Hes are joke artist. Donald trump has mocked everybody with personal attacks. If anyone deserves to be attacked that way, its donald trump. You know that is florida, they hate little marco rubio so much. Little more ka rubio 16, lying ted cruz, thats amazing no matter what you say with ted, hell change it. Today, gop candidates rally supporters in states with contests today and tuesday, and more of this. Get him out. Get him out of here. Trouble maker. A real trouble maker. Get that guy out of here, police. Thank you, get him out. Lets go, move we got to get him out. Were not going anywhere. All day. This is the place for politics. Even at this early hour, candidates are zigzagging across the country in what promises to be an exhaustive day for supporters in key states. Voters in louisiana will be the first to have their say with polls open at 8 00 a. M. Eastern, kansas is one of the states where donald trump and rival ted cruz are making their final pitches. Trump will also be in florida where marco rubio is campaigning. John kasich is in michigan as are Hillary Clinton and Bernie Sanders, both getting ready for a debate in flint tomorrow. Meanwhile the feud between trump and mitt romney is far from over. Trump began his latest line of attack against the former republican nominee as trump protesters began shouting in that rally in new orleans. That guy is mocking. He has no idea how to win. Hes upset. Hes upset because when he sees this happening, he never had it that way with him. You take guys that are jealous and guys that have lost and guys that dont know how to win like a mitt romney is an example. He choked so badly. That was an election that was easy. That was an election that could have been won so easily. Trump will be speaking in about an hourandahalf. Has he not cancelled at the last minute . Rubio, however, will be hitting it at 11 45. The other republican candidates addressed people yesterday, ben carson used his time to officially drop out of the race. You know, a lot of people love me. They just wont vote for me. Its okay. Its not a problem. You know, i will still be heavily involved in trying to save our nation. Donald trump is skipping cpac. I think somebody told him megyn kelly was going to be here, or even worse, he was told there were conservatives that will be here. You cant do it right. You cant have people in smoke filled rooms who are the establishment, be i the way, my only fear of a convention is that these kind of connected interests would dominate. Whoever the nominee is of our pare, they will get the full backing and t100 support of ou party. We dont take side, no matter what you read. The odds of a contested convention are very small. Msnbc is covering the cpac conference. Good morning to you both. We go ladies first, start with you, jane, i know that you were inside the Convention Hall when news of Donald Trumps cancellation broke. I am curious about the reaction then and the stuff you are hearing this morning. Reporter i think people were disappointing. This isnt Donald Trumps crew. These are establishment conservatives, libertarian, younger conservatives involved with the moviement for a long time. Donald Trump Supporters are newer to the gop at times. But i think peopleped to see him show his face and answer those questions. They might have been the Sticking Point if he didnt want to do the q a format that everybody else does when they come here. As for the buzz this morning, well, when the first speaker cancelled. I think a lot of people slept in. Its quiet. It looks empty. Except for you. Cpac officials have announced trumps choice sends a clear message to conservatives. Do you think he is in trouble with conservatives and all that conspired this week played a role in his decision to back out . I think he could be in trouble. He is certainly in trouble with conservatives in washington. Few look at last years speech, he went to cpac. He got a luke warm reception. I think it could have been quite controversial. Maybe he was going to get sol challenging questions, Newt Gingrich said it was a wise decision for him to skip cpac. Nomplally, of course, no one would skip cpac if you want to be president of the United States on the republican side. This year is very different. Hopefully, minnesota, jane, cpac wraps up today. Is there a sense from the conventiongoers the state of the gop race given all we saw from mitt romneys 68thing remarks ability donald trump to the behavior that we saw to the debate . Reporter you know, there are two sides of him. Here i think a lot of people enjoy what they tell me is a vacation from the election. They get to sit down and talk about the nittygritty policy and these tend to be policy nerds who want to spent spend three days talking about building the inner workings of the government. There is a sense they want the resolved and they want someone to win. They may not want it to be donald trump. We saw his name get booed a couple times yesterday. They want someone to win. There is talk of this brokerage convention idea. The top activists in the country, its not clear how that will work for them. Ted cruz made a compelling argument to a very intent crowd yesterday. A very happy receptive crowd that people who want not to be the nominee to be donald trump, but they want someone to win, they should vote for him. So, bob, mitt romney thinks if kasich wins ohio, they will knock the wind out of trump. Few look at a hypothetical, if this happens, trump holds the delegate lead. He needs to win 66 of remaining delegates to get to that magic number of 1237. That can be a hard climb. So what is your outlook on the path for anyone but rump . Well, i think its difficult an even romney has acknowledged that trump is the likely nominee and thats why hes stepped up and gave that big speech. There is no doubt about it. If trump keeps winning. If he win, i think either one of ohio or florida, winner take all. That is going to be a significant step to the nomination. He is not there yet, alex, but at the same time everything is falling perfectly for donald trump. If this were a twoman race, maybe that would change the dynamics significantly. Trump has been winning for months, until it changes, hes going to get the delegate seats he needs. With all the talk about taking down trump, you heard a minute ago, they were saying the rnc will back whomever the nominee is, adding the chance like you are saying the broker convention could be pretty small. Doong we should see more attempts like mitt romney to try to stop trump . Could it work or is it too late . Reporter i think its late in the game. We havent seen others step up and give that type of speech. Are we going to see that over the next week or two . I dont know, i think it depends on the results today and Going Forward. But it is late in the game and i think the postscript t. History will show, if trump gets the nomination, republicans waited too long and thought, well, hes going to implode. He hasnt imploded. Jane, real quick. 11 35, marco rubio, do you know when we expect to hear from him . Reporter we will see how strong the movement supports him. Im looking to see how strong his tournout is here. Will you see him get pressed in a brokered convention t. Moderator is here. Cpac has been pushing the candidates to get on the record. What do you think about that . Strong poll predictions, jane, are you hearing anything . You know, after yesterday, id say its going to be ted cruz, you know, time will tell. We will have to see how they vote. Yes, a few hours until that hams. Jane, bob, today to see you both, thank you so much. As we said, donald trump will be holding a rally, a last minute one in wichita, kansas, it comes an hour or so before the state caucuses begin. Then he heads to orlando and msnbcs Jacob Rascone is there for us. Good morning. Any effort there, any sign of slowing trump momentum . That effort is it working . Reporter the reality is, no, not at all, that even in all the states that have a poll out, donald trump is leading by double digits, except in ohio, where hes still leading if kansas where he is also leading. Hes a favorite to win everywhere. We wont really know, of course, until voters make tear decision. Some are looking at recent shifts in decision and policies and asking who is the real donald trump . Donald trump is playing by his own rules again, skipping the conservative cpac conference for a lastminute rally in kansas where the latest poll shows ted cruz catching up. This after a stunning weekend in America Politics of virtual civil war within the Republican Party. Each former nominee mitt romney slamming the front runner and refusing to vote for him. Im going to do everything within the normal political bounds to make sure that we dont nominate donald trump. Reporter the latest complaint trumps repeated flipflops on immigration. Suddenly arguing that the highly skilled Foreign Workers should be able to stay. Im changing him im changing. We need highly skilled people in this country. Reporter then releasing a statement, switching back and on torture. If i say do it, theyre going to do it. Reporter trump now telling the wall street journal he will not order a military officer to disobey the law. Now ten days and 13 states before the billionaire business mogul could be unbeatable. Or a contested convention could be all but inevitable. Once again its up to voters still flocking to trump rallies in record number, followed closely by scores of protesters and despite a week of unprecedented insults. He referred to my hand, if theyre small, Something Else must be small. I guarantee you, there is no problem. Reporter and party divide his opponents pledged they would support the eventual nominee. Even if it was trump. Ill support the republican nominee. Yes. Because i gave my word that i would. I will support whoever is the republican nominee for president. Reporter that, of course, was a big blow to the never trump movement, even those on stage with him saying they would support him if he was the nominee. Worth noting there havent been many polls out since this civil war in the Republican Party this week. We will see what happens on decision day today and again tomorrow and next tuesday. How right you are. Thank you, jacob. Well, the Democratic Candidates and the nations industrial heartland this week, Hillary Clinton and Bernie Sanders address workers intrigue. The two will debate in flint, michigan tomorrow, Kristen Welker is if detroit. Kristen, as always, good morning to you, my friend. How are these two candidates looking to make inroads with the nations workers . Reporter well, alex, first of all, senator sanders hoping to gain some momentum with these races today. His aides tell me the states vote today, in the coming weeks they say are more favorable to him. Secretary clinton downplaying expectations. They think they could have a very strong showing in kansas. They say nebraska is going to be a little bit closer. Those are two states you have a number of White Working Class voters who tend to favor senator sanders. Secretary clinton looking very advantage in louisiana. That could become a part of her southern firewall. Meanwhile, secretary clinton getting pressed again on that email issue after they struck an immunity deal with the fbi. He told investigators, though, that her server was never hacked. Heres what secretary clinton told cnbcs john harwood. Take a listen. This is the same security review that has been going on since last spring. Im happy that everybody now has been cooperating and giving information. Because i think that will finally end this and show that only appropriate steps were taken. Reporter alex, in terms of courting voters here, in the nations heartland, senator sanders has been really aggressively attackinging is clinton on trade issues for supporting past trade deals like nanta. Take a listen to what he had to say yesterday. She has supported nanta. I oppose nafta. She supported permanent trade relations with china. I vigorously oppose china. Ve supported trade relations with vietnam. I opposed that. She supported the colombia free trade agreement. I opposed that. And she supported the korean free trade agreement. I oppose. That. Reporter secretary clinton pushing back hard against that criticism yesterday saying she would only support a trade deal that favors American Workers and increases growth. She also called on senator sanders an gop front runner donald trump to release credible economic plans. Its all a preview of what we will see tomorrow night in flint, michigan, when these two face off in a debate. Kristen, thank you very much. Thank you for being outside in pretty dreary weather in detroit. Anything for you. Thank you. Coming up, could the republican establishment face backlash from rank and file voters following mitt romneys speech against trump. How the effort to squash trump could backfire next. Im encouraged on whats going on in the Republican Party. So well see whats pulling out here t. Lead horse can lead all of them when they speak. Because i dont trust any of them.

And thaptsz why when im president of the United States, this is so much fun by the way, when im president of the United States, we are going to undertake a reaganf style rebuilding of the United States. It looks like he is enjoying it, marco rubio is taking a swing last night in kansas, the florida senator is sitting in 3rd place headed into todays caucuses. He will have another shot of the gop frornt runner in maryland where he is expected to speak in about four hours or. So lets bring in rick tyler. Good morning. I want to get your take away at cpac. The conference schedule. There are reports. I know you heard him, he wanted to avoid a q a at the conference so for someone whose conservatives are already under attack. How bad is it he ditched this meet something. I was there all day yesterday and the day before, there was a lot of talk when it canceled, people were clearly disappointed. There was speculation about why he didnt show up and it seems to be that the organizers and the Trump Campaign couldnt agree on the format t. Format was quite simple. Everybody has to follow the same rules. You speak for 15 minutes then you take 15 minutes of q a from the audience. It seems to be that q a that was troublesome from donald trump. He decided to skip cpac. Its the premier conservative convention that happens every year here in washington, d. C. Ronald reagan attended the first one. He attended many subsequent once. All the president ial candidates have come through. So to skip cpac is sort of saying i dont want to face a conservative audience. were seeing an establishment backlash against donald trump. Mostly recently mitt romney, of course, john mccain. But the polls are showing the rank and file republicans are doing much pro trump. Navenl, heres one interview by the new york times. Heres a quote. You are telling me who to vote for, who not to vote for . Please, there is nothing short of trump shooting my daughter in the street and my grandchildren, nobody is going to persuade me from voting for trump. Rick, do you think the party is losing control of its members and what does that mean Going Forward even looking past november . Well, one thing is clear, after super tuesday, is the establishment has lost, they dont have a front rung establishment candidate. We had that with bob deal. We had that with john mccain, we had that with mitt romney. The conservatives in the party dont trust the establishment because they keep saying just if you conservatives help us win majorities. We won one in the house and subsequently one in the senate. Will you get all you want. They delivered nothing. In fact, they believe and the republican aides are probably rye the Republican Party was better off with harry reid and nancy pelosi in charge of the house and the senate, there was no conservative difference over the conservatives. Now they say if you give us the white house, everything will be okay. To bring mitt romney back when he wasnt there to endorse a candidate raised a lot of suspicion. It looked as if romney was positioning himself for some sort of brokered convention. This is exactly what the rank and file is all very suspicious about. So i dont think it helped at all that romney would come out and be critical of donald trump. I appreciate what he said, but the way he did it and who it is is problematic for the party. What do you think about romney . Look i campaigned hard against romney. I was a conserve tiver for Newt Gingrich. Romney did not have the deeds. He didnt have the record. Similar to donald trump. Donald trump does not have a conservative record. He, in fact, has supported almost everything 180 degrees at a phase of what he says now, so if you look at tarp, bailout, foreign policy, you look at he says i was against the war in iraq. He was for the war in iraq. When you look at tax policy, when you look at National Health care, i hate obamacare. Yet he talked about having a single payer system in the past. Hes been pro abortion, pro gay marriage. All these things are 180 degrees out of phase. So he is really no different. I under
