Al tackles 13 states in one day on his quest to hit all 50 in a week. Hes made it to the Mighty Mississippi, and its pushing ahead to the Halfway Point, tuesday, november 10, 2015. Announcer from nbc news, this is today with matt lauer and Savannah Guthrie live from studio 1a in rockefeller plaza. Good morning, everybody. Welcome to today. Its a tuesday morning. Al has gone through 22 states, trains, planes, automobiles and covered wagons apparently. And were talking boats now. Along the Mighty Mississippi, but thats a big river. Al, exactly where are you . We are at cape gerardo, matt, here along the Mighty Mississippi in one of the fire boats, so we are on the mississippi, and monster monday became part of terrible tuesday because we didnt land here until about until about two hours ago, so weve taken one too many hits with the punchy stick but were ready to go. Which should make for a fun show. I was going to say that might have happened with you yesterday. Lets start with our top story, the republicans running for president gearing up for the debate showtown in milwaukee tonight and all eight candidates have something to prove for the voters. We begin with National Correspondent peter alexander. Good morning to you. Reporter you said it. With only eight candidates on the main stage, four on the undercard and three on the sidelines, all together how will this go tonight . We expect to hear more from each candidates. Among the biggest questions, will ben carson need to fend off attacks from donald trump, and how does jeb bush handle the for the republicans tonight poses another crucial test. Frontrunner ben carson dismissing growing scrutiny over apparent discrepancies in his life story l. Carsons rivals or even the debate moderators grill him tonight. His chief opponent donald trump is already teeing off, focusing on carsons description of his violent youth. This is the only election in history where youre better off if you stab somebody. What are we coming to. Reporter carsons Business Manager tells nbc news the controversy has lit a fire under the usually calm candidate. I think finally he had an epiphany in real life, that, look, i have got to be ready for these moments. Bring it on. Im ready to fight. Reporter with the economy in focus tonight, trumps challenge, to emphasize substance over style and show how his billionaire Business Savvy would translate to a trump presidency. Marco rubio is gaining ground, but tonight can he put to rest questions about his spending habits while in the Florida Legislature . Tonight could offer a sequel to the last debate showdown between rubio and his former mentor jeb bush. Someone has convinced you that attacking me will help you. Reporter tension between the two underscored by a New York Times report out this morning that allies of bush are privately threatening a wave of scathing attacks on his former protege in the coming weeks. According to the times 100 million Bush Superpac right to rise has filmed a video of rubio as unelectable because of his hard line stance against abortion and his missed senate votes, all signs about how nervous they have become about the bush candidacy. Analysts point out he cant afford another lackluster performance and on the trail hes got a new slogan jeb can fix it and hes showing a different side of his personality. The three questions, better than the moderated debate questions, just saying. Raucous debate on cnbc the moderators tonight from the wall street journal and fox business are promising this one will be a civil affair. Foxs Maria Bartiromo telling the candidates that they should be prepared to answer any question, in her words, its all fair game. Matt and savannah. All right, peter, alexander in milwaukee. Thank you. Nicolle wallace is an msnbc analyst and former White House Communications director for president george w. Bush. Steer karnaky is an msnbc host and political correspondent, folks, nice to see you both. Ben carson is under fire and lashing out at the media saying hes being vetted harder than any other candidate has been. How will it affect his performance tonight . The question has to do with how doed moderators and fellow candidates respond after the criticism with what the debate format, gotcha questions and focusing on too much nonissues. Does it give him an out whether its a moderator or fellow and donald trump who has lashed out of some of the inconsistencies and buy graphical data aside the other candidates are in a you have to position because they have reaped the benefits of attacking the media. If they attack carson on these stories they are doing for blaming what the media can do. And carson can say to them you are doing the bidding of the liberal media and that could be a devastating comeback for him. Jeb bush, how many times have we sat here together saying jeb bush has to have a good night. Interesting art call in the New York Times saying jeb bushs superpac is ready to throw tens of millions of dollars at attacking marco rubio. Does that say let the superpac do the dirty work, we wont see the bush versus rubio manoamano because it backfired so badly in the last debate. Listen, they do not spend any time in their Campaign Headquarters how to beat ben carson and donald trump. They spend all the time how to win that establishment lane, how to beat chris christie, governor kasich and marco rubio so their strategic imperative is to top rubio, and at the moment rubio has the momentum coming out of three strong debate performances and feeling as though they have dodged a bullet in the press. You mentioned chris christie. Had one of the best weeks of his Campaign Last week and yet he goes down to the undercard in tonights debate. Hes got to be disappointed by that, but might it not be an opportunity for him to dominate that debate, get a lot of camera time and break out in some way. Exactly. And weve seen this before. Carly fiorina in the first under card debate back in august, got such great reviews it vaulted her back to the main stage. Christie needs to get back to the main stage so there is an established pathway. Forget the National Poll and look at New Hampshire. Hes moved up, quadrupled his support in New Hampshire over the last two months with the town hall meetings. It was what john mccain once did. Trying to follow that path. For better or worse in this cycle, debate moderators have really become part of the story line. If youre fox and youre hosting this debate tonight, fox business, how do you handle that . On the one hand you dont want to subject yourself to the candidates going after you, going after the media, a proven winner for them but on the other hand you dont want to pull your punches. Fox has a special place in the hearts of republicans so they go into it with a lot more goodwill with every one of the single men and women on the stage. Megyn kelly and bret baier, subjected to the same kind of scrutiny that cnn has been and to some extent cnbc has been. I think they will play it straight. No signs that they plan to pull punches and go into it with a lot more trust from the campaign. Guys, thanks very much. Well be watching. Federal Appeals Court has dealt a major new blow to president obamas plan to protect millions of people from being deport the. Nbcs justice correspondent Pete Williams is following this story. Pete, good morning. Reporter good morning, savannah. Another legal setback for president obamas plan to shield up to 5 Million People from deportation allowing people here illegally to stay if they have children who are citizens and expanding that program to let young people stay who were brought here as children. By a vote of 21, a federal Appeals Court agreed with texas and 25 other states who claim the administration illegally tried to put this policy into policy without getting Public Comment first. The Appeals Court rejected the white house claim that the plan just shifts enforcement priorities. Instead, the court said the heart of the plan would give benefits to people here illegally, including Social Security and qualification for work permits. Texas says that would impose a big cost on the state, just for all the new drivers licenses it would have to issue. The administration can now appeal to the u. S. Supreme court, and if it acts soon it would be in time north justices to take up this issue during the courts current term. Savannah, matt. To be continued on that. Pete williams, thank you.
