We are all in this together and we will come up with solutions and find the answers to things and so far i cannot believe how civil it has been up here. It was a Republican Debate unlike any other so far this campaign season, the yelling and name calling giving way to a relatively respectful discussion of the issues. Good morning and welcome to your world this morning im delve walters and stephanie sy has the day off today. Last nights debate in miami was the last time the candidates will gather before next weeks contest and winner take all for republicans on tuesday in florida, ohio, illinois, North Carolina and missouri and our Political Correspondent michael shore live for us in miami this morning and michael no name calling, no personal insults about hand slide and no moderator bashing, what happened . Delve, i dont know, i feel that the democrats showed up for the Republican Debate last night. It was long on substance and i feel when he came out the chairman of the Republican National committee to be the warm up act for the debate he said to everyone assembled there this is going to be about unity and coming together and got the feeling the candidates were told not to told not to call each other out and snipering and it was a different tone last night in miami. Unlike previous debates characterized by personal attacks and discord the debate in miami talked about economy, education and foreign policy. The first question of the night went to Governor John Kasich whether his support of trade deals was under mining, it and he played up his blue collar routes. Wanted free and fair trade and when countries cheat and take advantage of us we need to blow the whistle. Reporter candidates differed on the issue of Social Security solvency. My children would retire at 70, my at 68, a graduating scale over a period of time. I want to make America Great and leave Social Security as is it and get rid of fraud and abuse. Reporter but marco rubio challenged donald trump on the numbers saying they simply dont add up. Get rid of fraud and abuse and careful how we spend foreign aid but you still have hundreds of billions of dollars of deficit you are going to have to makeup. Reporter cruz suggesting donald trump has a history of giving money to both sides. If you have a candidate who has been funding liberal democrats and funding the washington establishment its very hard to imagine how suddenly this candidate will take on washington. Reporter trumps response. We are all in this together, we will come up with solutions and find the answers to things and so far i cannot believe how civil it has been up here. Reporter naturally being in miami the conversation drifted to diplomatic relations with cuba. Miami is home to the largest cubanAmerican Population in the country. Both cruz and rubio are of cuban decent and asked about president obamas decision to renew diplomatic ties with the caribbean nation the candidates spoke up. Cuba and its regime remains antiamerican communist dictator shift and e vat u. N. Sanctions and fugitives of american justice including people stealing medicare money and moving back to cuba all in exchange for nothing. Reporter trump was questioned by cnn moderator tapper about resent incidents of violence at his rallies. Come with passion and love for the country and protest in some cases and you mentioned one case i have not seen, i heard about which i dont like but when they see what is going on in this country they have anger that is unbelievable. Reporter possibility of a brokered convention looming trump painted a primary process he says boils down to two candidates ted cruz and himself. Im going to have the delegates i think. Lets see what happens. Whoever gets the most delegates should win is what i think. If you are one of the 65, 70 of republicans who recognizes that if we nominate donald trump hillary wins that is why the media wants him to be the nominee so much. If you recognize that then i want to invite you if you have supported other candidates come and join us. Reporter the next big republican contests are tuesday where ohio and florida home states of kasich and rubio will be up for grabs. Delve already here in florida 67 of the number of people that voted in all of 2012 in the primary have already voted here in florida in early balloting not to mention also 220,000 ballots were cast before jeb bush the former governor of this state even left the race, pretty interesting stuff. Remind you of the scene from Butch Cassidy and the sun dance kid who are those guys and donald trump will pick up a very significant endorsement tell us about it. Dr. Ben carson you remember of this race a little while ago left and the last candidate to leave and have been so many but im pretty sure he is the last to leave he will be endorsing donald trump and interesting endorsement because we knew cruz and carson and cruz feuded in iowa and donald trump had to fight to get the moral high ground of any kind is getting it from the person who advertised himself as the moral high ground so its going to be an interesting match the two of them. He has already said in the debate last night he likes dr. Carson on education, wants dr. Carson to be a leader in his administration on education but of course donald trump also said he wants to abolish the department of education, curious anyway delve. Michael for us in miami thank you very much, as you heard michael say ben carsons endorsement of donald trump coming at a time when opposition to trump is getting louder and growing protesters showing up at rallies and they are not peaceful and Al Jazeera David shoe sterhas more. Get them the hell out of here. Reporter after those angry words from donald trump there is more evidence of angry deeds by his fans. The latest came wednesday in North Carolina on the right watch the man with the red sleeves, brown hat and ponytail. Following the sucker punch police handcuffed and removed the African American protester who had been hit. Later Police Charged the attacker with assault, an unapologic man known as john mcgrew. What was that . Yes he deserved it and the next time we see him we may have to kill him. Reporter the episode is the latest trump event marked by violence. Trump faithful have literally dragged protesters and cursed and spit on them. The gop frontrunner has not exactly been quick to criticize the slashes. If you see somebody getting ready to throw a tomato knock the crap out of them and he is walking up like a high 5 and smiling and laughing and would like to punch him in the face. Reporter his tone is frightening especially with his resent call at some rallies for loyalty pledges. Raise your right hand. I do solemnly swear. Reporter the Campaign Says it helps Security Team identify potential troublemakers and antidefamation lead has been a ho hold haulcost and its obnoxious and disgusting and president obama fired back at republicans says his administration fueled trumps rise. I have been blamed by republicans for a lot of things but being blamed for their primaries and who they are selecting for their party is novel. Reporter the president insisted that trump is the product of the Republican Base and conservative Media Outlets who have insisted that any compromise with the Democratic Administration is a betrayal. What im not going to do is to validate some notion that and the republican crack up that has been taking place is a consequence of actions that ive taken. Reporter david with al jazeera.
