Becoming an International Superstar is just something i did while waiting for my next assignment. And going urban. A huge crowd packs the plaza for a live concert from country superstar keith urban as our long, hot summer continues on friday, august 7, 2015. Good morning. Welcome to today on a friday morning. It is a great morning for a great concert. Weve got keith urban here live and several thousand of his closest friends here to watch the concert in our 8 30 half hour. I dont have to ask if you watched the debate. We were texting each other during the debate. It was fascinating at times, exhausting at times and it is the subject of our top story. We have the big moments, the nights impact on the race moving forward beginning with nbc National Correspondent peter alexander. Peter, good morning. Reporter matt, good morning. If you were looking for a good debate night to kick off the political season, this one didnt disappoint. It was raucus, feisty. Donald trump debating for the first time didnt shy away from the spotlight. Afterward he complained some of the questions to him were much tougher than to anybody else. He said at times they were simply not nice. It started with a show of hands but only donald trump raised his. Mr. Trump reporter re fusing to commit he wont run as an independent. You cant say tonight you will not make the pledge. I cannot say. Reporter rand paul quickly pounced. Hes already hedging his bets because hes used to buying politicians. Well, i have given him plenty of money. Reporter trump also tangled with moderators after disparaging comments about women. You have called women fat pigs, dogs, slobs and animals. Only Rosie Odonnell. The problem this country has is being politically correct. Reporter odonnell tweeting, try explaining that 2 ur kids. Jeb bush dismissed trump as a divisive figure. Well win when we unite people with a hopeful message. Reporter john kasich declined to attack the frontrunner. Donald trump is hitting a nerve. People are frustrated, they are fed up. Hes got his solutions. Some of us have other solutions. Reporter Democrat Hillary Clinton was a target they could all agree on. How will Hillary Clinton lecture me about living paycheck to paycheck . I was raised paycheck to paycheck. Reporter trump, who contributed to the Clinton Foundation batted away questions about whether he was too cozy with the clintons. With Hillary Clinton i said be at my wedding and she came. Do you know why . She had no choice because i gave. Reporter one of the nights sharpest exchanges, Chris Christie blasting rand paul for fighting to put limits on government surveillance. When you are sitting in a subcommittee just blowing hot air about this, you can say things like that. I dont trust president obama with our records. I know you gave him a big hug. If you want to give him a big hug again, go right ahead. The hugs i remember are the hugs i guay to the families who lost people on september 11. Those are the hugs i remember. Reporter the debate touched on everything from immigration to planned parenthood. I defunded planned parenthood long before any of these videos came out. Reporter the night wasnt without lighter moments like this from neurosurgeon ben carson. Im the only one to separate siamese twins, take out half of a bryn but you would think in washington someone beat me to it. Reporter this morning donald trump was complimentary about what he described as worthy opponents including jeb bush, marco rubio and ben carson. Unclear what this will do to shake up the field going forward. Carly fiorina was very strong in the earlier debate. The republicans arent on stage together again, matt, until next month. Peter alexander, thank you very much. Senator marco rubio joins us now from cleveland. Senator, good morning to you. Good morning. I have been reading some of the reviews on your performance last night. I will pa are a phrase and sum them up. People said you may not have broken out last night but you certainly answered in a positive way some questions about your electability. Are you happy with that review . Yeah. With the reviews that matter are not the pundits. Its the people watching that have to make the decision at the ballot box. This is the first time well debate together. There will be multiple other opportunities. This is a Long Campaign for the most important Political Office in the world. I was honored to be a part of it. Im looking forward to future ones. Donald trump refused to rule out a third party run. He says hes using it as leverage to make sure the party treats him well. Sounds like a threat to me. How does it impact the way you and other candidates take him on directly . It doesnt impact it at all. Im not running against any of the other people on that stage. Im running for president. I will continue to do what i did last night. I will tell people where i stand and what i will do if elected and voters decide. Thats the great thing about living in this republic is the voters decide. What other people are doing doesnt necessarily impact our strategy or what we are saying. Let me ask this way. As you stood on stage last night listening to what he said, watching what he did, did you find yourself thinking, if i am not fortunate to be the nominee of this party i could enthusiastically support donald trump to be the next president of the United States and commander in chief . Yeah, look. I think i have confidence in this process. I have confidence that the republican nominee is going to be a republican. I have confidence that the nominee will be someone who is optimistic about america. I dont believe america is losing to everybody. I think this is the greatest country in the world. I know we have problems, we have challenges, no doubt. Right. Who would we trade places with . What country in the world would we trade places with . Thats the message that will ultimately win. I will ask you again with all due respect. Do you think donald trump has what it takes to be the president and commander in chief . I dont know. I dont think thats been answered about anybody in the race. I feel confident about me. But thats why we have a campaign. Thats why we are going to have multiple debates and people have to answer questions. Over the next few months thats what the campaign is about is determining and answering questions like that. None of us are owed the position by virtue of our fame or how much money we have raised. We have to go out and convince people. Last night was part of the process where voters get to see us answer tough questions and from that make a decision about whether they are going to turn over the most Important Office in the world to one of us. Senator marco rubio. I appreciate your time this morning. Thank you very much. Good luck. Thank you, matt. All right. Which candidates expect to get a boost from their performances last night . Chuck todd is nbcs political director and moderator of meet the press. Good morning. I have heard more than one pundit say im out of the game predicting what will happen with donald trump. The rules dont appear to apply. Do you think he helped or hurt himself . It was an audience of mostly republicans. Yes, there were others that wanted to watch the event. And to start off by saying i wouldnt necessarily stay in the Republican Party, you have automatically shut down your ability to grow your support. Look, i understand why donald trump is upset with the moderators. They put him on the defensive from the beginning making that the first question. Put him on his heels, no doubt about it. I think it will hurt him. But youre right. He defied political gravity before. People thought it was a big night. It had to be a big night for jeb bush. Did he live up to what he needed to do . For the first time he looked like he didnt like to be there. Sometimes you get the feeling just going, gosh, i cant believe ive got to do some of the things i have to do before i campaign the way i want to campaign in a general election. But i thought the moment with trump peter highlighted in the package there where he stood by his criticism of trump and when trump had the chance to you thought maybe he would pounce, trump acknowledged it was a fair criticism on tone. Let me tell you why. It guay jave jeb the moment. It could have been a bad moment for jeb and it was a good one. A couple of hours, you try to get to the substance. You can take the measure of people in a situation like that. For you, who was the stand out . Who helped themselves last night . The person who helped himself the most was john kasich. This is a guy nobody knew a lot about. We kept saying, hey, watch this guy, watch this guy. Hes going to get that second, third look. Marco rubio, there were concerns from some of the establishment, the elite going wheres he been . Hes gone away. He had a good night. Scott walker, sometimes you wondered where he went. For a frontrunner he didnt make any mistakes but for a frontrunner he disappeared too often. As debates go on he needs to look for alpha, president ial. Let me not let you leave without asking about a big headline last night. Chuck schumer said he will oppose the iran nuclear deal. How big of a blow is it to the president s attempt to get it through congress . He tried to do one favor. He announced it during the republican debate. He tried to bury the news a little bit. Hes clearly not campaigning against the deal. The fact that the other new york senator who rarely splits with him on foreign policy, kristen gillibrand, she came out for the teal and three, four hours later schumer came in. Hes opposing it but seems to be trying to oppose it, not campaign against it. If youre the white house, could have been worse. You have a lot for meet the press. Well see you sunday for sure.
