He had come in second before. Now hed run and hed win, but mccain got into the race in early 2007. After that, just about everything went wrong for him. By the summer of 2007, john mccains campaign looked dead. His poll numbers had collapsed. His fundraising evaporated. He was shedding staffers. People were abandoning the Campaign Like a sinking ship. Political guru Charlie Claire declared, it is effectively over. It is the executers of the state that are taking over. That was the diagnosis of the Mccain Campaign in the summer of 2007. He reorganized. He concentrated his efforts on the New Hampshire primary. He gave new policy speeches. He put out an ad focusing on his prisoner of war experience. He debuted a feisty new persona in debates. In mccains case in 2007 and 2008 it worked. He went on to win New Hampshire. He went on to win the republican nomination for president. It was a successful example of the campaign reboot, but most reboots are not nearly as successful as john mccains was back in 2007 and 2008. Back when his campaign was struggling last fall, jeb bush would frequently invoke the example of mccain, promising that he, too, would bring his campaign back from the dead. But when bush attempted a reboot in october of last year, when he embraced his father and embraced his brother after months of trying to distance himself from them and from their history, when he tried that, it didnt get him anywhere. In 2012, mitt romney made so many attempts to refashion his campaign that the onion ran the headline Romney Campaign reboots for 72nd consecutive week. If there was ever a candidate seemingly in need of a reboot, a big reboot, it had to be trump at the end of last week. That week was full of so many perceived problems for the republican nominee, providing so much material to his opponent that clinton made a web ad more than a minute long. It was a list of all the things that donald trump had said, done, or caused. Actually, i was only kidding. You can get the baby out of here. I think she might believe me that i love having a baby crying while im speaking. I always wanted to get the purple heart. This was much easier. So that was Donald Trumps week last week as seen through the eyes of the Clinton Campaign and as seen through the eyes of plenty of americans. Clinton leading in every Single National poll that came out last week. Pretty much all of the swing state polls that came out last week too. In fact, trump was down 15 points in a poll that came out last week. That was a bigger margin than mitt romney had faced at any point during the 2012 election. By the way, the polls havent gotten any kinder for donald trump today. Were going to get to that in just a few minutes. Last friday night in the face of what had been the worst week his campaign had endured since he came down that escalator and got into the race, last friday night donald trump seemed to make a gesture toward trying, at least, to repair all of that damage from the week. He was in wisconsin for a rally and on stage there he read haltingly from a prepared statement. He took a piece of paper and read from a statement endorsing paul ryan and john mccain and kelly ayotteayotte. Some of those are the big name republicans he had refused to endorse. Donald trump reading from a script. Donald trump seeming to make the advice of his political advisers of the voices around him. All of that got some people wondering did all of the bad news finally get to trump. Did it shake him up just a little bit . Did it convince him he needs to adopt a different style, a different approach . That was the question raised of how friday night went for donald trump. At the next day on saturday, trump was back to his free wheeling, unrestrained self. He went after Hillary ClintonsMental Health. She is a totally unhinged person. Shes unbalanced. All you have to do is watch her, see her, read about her. She will cause, if she wins, which hopefully she wont, the destruction of our country from within. The people of this country dont want somebody thats going to short circuit up here. Okay . Not as your president. Not as your president. Im going to spend a minute more on Hillary Rodham clinton. Honestly, i dont think shes all there. Today it appeared that even trump knew going after clintons Mental Health wasnt going to be enough to dig him out of that deep hole that he got himself into last week, so today it was time for a reboot. And for the reboot, trump went to detroit, michigan, to the detroit economic club. There he delivered a speech on his economic agenda, and he stayed pretty much entirely on the teleprompter for his speech today. He was reading through prepared remarks and he sounded this is a relative term with donald trump measured standing there at the podium and reading this speech. Even kept his cool during the 14 interruptions by protesters during the speech. If trump looked and sounded like more of a traditional president ial candidate, one may be listening more to his advisers than he had been before. The economic agenda that he laid out sounded like a traditional republican candidate than anything we have heard from him before. I am proposing an across the board income tax reduction. We will work with House Republicans on this plan using the same brackets they have proposed. 12 , 25 , and 33 . Under my plan, no American Company will pay more than 15 of their business income in taxes. [ cheering and applause ] in other words, were reducing your taxes from 35 to 15 . I am going to cut regulations massively, massively. Finally, no family will have to pay the death tax. Now the death tax that trump is referring to there is the estate tax. Thats its more formal name. This is a favorite and time target of republicans. That said, trump also spent some of his time on his signature populist economic issue thats getting out of trade deals like nafta, but mostly this was traditional republican economics that he was preaching today. It was greeted enthusiastically by the largely corporate audience at the detroit economic club. Hillary clinton is due in detroit for her own economic speech later this week, but she wasted no time going after trumps speech in st. Petersburg, florida, this afternoon. Today in detroit, hes got i dont know a dozen or so economic advisers he just named, hedge fund guys, billionaire guys, six guys named steve apparently. So they wrote him a speech and he delivered it in detroit. They tried to make his old, tired ideas sound new, but heres what we all know because we heard it again. His tax plans will give super big tax breaks to large corporations and the really wealthy just like him and the guys who wrote the speech, right . So the trump reboot, the trump version of a reboot, on display in detroit today. Time will tell if it has staying power or if clintons narrative will overtake it or if it will only last until the next time trump veers off script. Joining us now is the nbc correspondent who has covered donald trump ever since he started his run for president. She joins us now. Thanks for taking a few minutes. Let me just start by saying it is sort of remarkable. Its after the republican convention. Were in the general election season now, and were watching this speech today saying it is remarkable that a majority partys nominee is reading a prepared text. Yet that is a commentary in a way on how unusual the Donald Trump Campaign is. What is it that convinced donald trump to go out there and do something conventional today . Thats not been the donald trump recipe. Well, you know, he had a chorus of folks try to tell him he needed to get back on message. I think ultimately it was the poll numbers. Donald trump is down in almost every poll right now, including double digits in National Polls and double digits in some important swing states like New Hampshire. Also in pennsylvania down by quite a bit. For somebody who has been watching the polls as closely as he has for the last year and a few months, i think it is the impetus to get him to start changing. I spoke to Trump Supporters at his rallies. I asked them what would their one piece of advice would be if they were to talk to donald trump about his campaign. They said to get away from the controversies, to get back on message, to talk about the economy, job creation, National Security, the sort of things you heard him talk about today, but its donald trump. Ultimately theres very little expectation from those in the gop at least that hes going to be able to stay on message for very long. Yeah, case and point, he gave that speech this afternoon within a few hours. He was tweeting about this case in iran of the Nuclear Scientist who was executed there, convicted of spying, convicted of giving information to the United States. Donald trump tweeting, many people are saying that the iranians killed the scientist who helped the u. S. Because of Hillary Clintons hacked emails. Now, we should stipulate that is a debunked claim donald trump is putting out there and yet hes putting it out there. This is exactly the kind of Conspiracy Theory sideshow that his advisers are pleading with him to avoid. It took him six hours to do it. You know, senator tom cotton was the first one to float this the other day on a sunday show. Now donald trump is tweeting about it. Hes been prone to tweeting about it and talking about conspiracy theories. Remember, he talked about ted cruzs father being linked somehow to the assassination of jfk. Hes also one of the first birthers out there trying to say president obama wasnt born in this country, so conspiracy theories has always been something that donald trump has been has enjoyed pedding essentially. And this is what he is doing today. Why is he doing it on this day when he is trying to reset his campaign . He is often trying to change the subject. The only thing that i could think of that could have happened today that he would want to divert attention away from is the fact that 50 leaders came out and said he was reckless and not qualified to be president of the United States. Donald trump released a statement pushing back on them, saying they were the ones who got us into the war in iraq and they were the ones who enabled isis rise. After that is when you saw him tweeting about this iranian Nuclear Scientist. If youre going to ask me what could he possibly be doing, well, changing the subject away from something that could be damaging to him. Katy tur covering the Donald Trump Campaign.

This is a republican member of the United StatesSenate Susan Collins from maine. Shes represented that state in the senate since 1996. She has published an oped in the Washington Post entitled why i cant support donald trump. This is not a decision i make lightly, for i am a lifelong republican, but donald trump does not reflect historical Republican Values nor the inclusive approach to governing that is critical to healing the divisions in our country. This is Susan Collins. This will be in the print edition tomorrow. It just went online in the last few minutes. Susan collins saying in this piece there are three reasons she ultimately decided she could not support donald trump. Number one, she said it was his mocking of the disabled reporter.

And the most recent controversy in the last two weeks with the khan family, the war of words donald trump engaged in with the khan family. Susan collins saying that donald trump has shown, quote, a complete disregard for common decency. She also said shes been troubled by his, quote, constant stream of denigrating comments that she hoped donald trump in emerging from the republican primaries with the nomination that there would be a new donald trump, somebody she could get behind. She now says she is convinced that is not the case and she will not vote for donald trump. Another key point here, Susan Collins does not say in this oped who she will vote for. No mention of Hillary Clinton. No mention of the libertarian. No mention of any other candidates. Susan collins republican senator from maine saying she will not vote for donald trump for president.
