state on saturday. he'll finally make a pilgrimage to the butter cow t the state fairgrounds. he's ready even if they aren't ready for all trump has to offer. he reportedly set to set up a the thrill ride to offer kids rides in his helicopter. the state fair didn't like let the idea get off the ground. trump is still feuding with the paper after an editorial called for trump to pull out of the race. the soap box will still see plenty of foot traffic. jeb bush tried to prevent himself as the most viable candidate. >> i campaign the way i would govern. out amongst everybody. no rope lines. totally out in the open. i campaign in the latino communities in spanish asking them to join our cause. i campaign in the african american communities saying join us because we believe in education reform so your children can be lifted up. >> mike huckabee also graced the modest but mighty stage. he too began to slam hillary clinton. >> you hear a lot of people come to your state. this time 17 republicans are coming to iowa to ask for your vote and support in the caucuses. there will be a handful of democrats who will come as well. hillary probably is not going to come. she'll e-mail in her i person'ses. >> the wisconsin governor stole the hearts of iowa dur the faith and freedom throw down. despite rocky history donald trump has ripped ai out from under walker. in july walker held a commanding lead. in the latest poll by cnn walker is down to 9%. donald trump is a double digit lead over the conservative darling. but the real test comes after the hard rounds of campaigning at the fair. candidates have flooded iowa and voters are ready to find out if trump is the real deal. joining us live from hampton, new hampshire is nbc news reporter kate terr. >> they are waiting to find out if he is the real deal. he is going to be doing a big event attended my hundreds to many thousands depending how much show up and that is what he's doing generally is going to these big rallies and giving his general stump speech. he hasn't given any details though. and here in new hampshire that is what the voters are used to. they are used to candidates coming out and doing much smaller vents and talking to people one on one and laying out plans. trump's only been here about 16 times. other candidates have been here over 60 times. fiorina is mush lower in the polls and he has all these ability to do national media to get his face out there and at least what he says are his ideas out there on a national stage. but when i'm talking to voters here even when i'm talking to trump staffers here, they do want to hear more policy plans for him. more details. they want to know how exactly he's going fix immigration. how he's going to deal with the 11 million or so undocumented immigrants in this country and how he'll build that wall. not to mention his tax plan. i have spoken to people in the campaign who say that is coming out soon but when you ask what soon means they just say soon. so that could be tomorrow, today, three weeks, a month. i don't know. soon. >> right. soon. huge soon. so does donald trump show any signs of scaling down his campaign? it doesn't appear. but do voters want to interact with him in a more intimate and smaller setting? >> i think they do. and i think there is a good portion of voters who want to do that because they want to hear what his ideas are. they want to see how he's going to go in and shake up washington. they want to know who he's going to put in place in these major positions. not a lot of them think that he necessarily has all of the answers or all of the ideas. but they do have a faith in him that he's going to be able to choose the leaders for the appropriate positions. and when you ask him how they know that a lot of them cite the apprentice. which is interesting because the apprentice is a reality show. but they were able to get some sense from him in that show rightly or wrongly that he is a good leader. but i don't expect to see him doing that. i think trump is a big showman. i think he's huge. i think he likes to do things on a grand scale and he likes to be the biggest, the best, the goldest, if you will. so i don't expect to see him doing any small intimate things. i expect him to be doing these big events for the foreseeable future. at least as long as it is working. if he starts to dip in the polls anything is possible. when you ask what ooex next they just say trump is trump. >> he can trumpet himself, no doubt. let's shift to iowa. do you think trump will be missed at the soap box since he's still beefing with the newspaper there? >> yes and no. i this i people are going to come out and see trump for the spectacle that is trump. so there is going to be the true believers and also people who just like the celebrity of it. he's landing on a baseball field about a half a mile from the iowa state fair and then he's doing this slow entrance on a golf cart into the fair as god knows how many press people and media reporters like me are going chasing after him. so it is going to be a scene. he is also looking into the helicopter rides. we're told that the campaign is feeling optimistic that they are going to be able to do that. so what you are going to do see is trump giving helicopter rides in his trump helicopter if they are able to people at the iowa fair. even though he's not getting on the soap box and giving out some speech he is going to be the biggest presence tomorrow. make no mistake. >> if you snag a ride please report back to us. >> i will. [ laughter ] >> katie tur, thank you. joining me now is my panel. susan, let me start with you. scott walker was the conservative darling of the gop. a lot of koch money but he's dropped in the polls. what do you suspect is going on there? >> well he did get off to a rocky start after his announcement. and then to not perform at a level that people expected him to do at the debate was definitely huge. that east really what i think -- >> no one intended. >> yeah. sorry. >> don't fire him. >> but i do think that hurt him and hurt any momentum he could have gained from hit. he really needed to hit it all of the ballpark and didn't. and donald trump is sucking the oxygen out there. and he's now put, you know, ten people on the ground in iowa. that is really significant. and the fact that he's taking it finally serious like a campaign and building it out tells you he is in this and that is going continue to hurt a lot of candidates especially scott walker. and it is no accident that not only is he not doing the soap box and there are a whole host of issues probably why he's not doing but only one republican candidate is doing it tomorrow and that is rick santorum. >> henry, susan spoke about a lot of the oxygen being sucked out of the air by trump. he has those big arena events and wide open field events. during people are hungering for the more intimate events? and will it play to trump's advantage? >> i think trump is doing what he ought to be doing actually. i think what's happened in iowa and we're seeing in new hampshire he's leading in both states. is that republican voters are now after citizens united in a situation where they can choose among candidates who are funded heavily by billionaires. and we've seen rick perry actually doesn't have enough money to pay staff. yet flush in his super pac. and i think we're now where republican voters are saying i can have a candidate fought and paid for by a billionaire or i can pick a billionaire. and since they can pick a billionaire they are doing that because then they know who they are actually supporting. and i do think he is going to have to start to talk about policies. if he doesn't he may actually continue to do well on the republican side. but he won't transaattract independents. >> is he smart right now to play to his advantages and strengths, skipping the soap box stuff, and ramping up in the open fields and creating a interest in his candidacy will that will puch push him a long way. >> at some point he'll have to talk policy but i agree with henry he's doing what he should be. and it is working because he's at the top of the polls and at the top of the these two polls. if scott walker doesn't win iowa, i mean i know it is early but that is devastating to him. the thinking was he's going to do that. it is the neighboring state. do you know what? being a neighboring state back fired on him because they are seeing the head lines cutting a quarter of billion from university of wisconsin. one scandal after another. budget problems. i think that is one thing donald trump is doing is making it very hard for scott walk tore proceed. >> in these events he's having, we have to remember tease are very well orchestrated crowd building events with a lot of security and he's speaking to people that it's all laid out. when he goes into iowa he is still going to have to gland hand really for the first time. and from what i understand he's a bit of a germaphobe. it may be an issue. we see he gives these great speeches that people -- you know, you can argue if they are great. but he gives speeches that are very well received. and that is rising up the support. but when people in iowa and new hampshire, they do want to touch the candidate. they are used to it. they expect it. so he has to do some of that. and it will be interesting to see how he does. everyone said he'll never do this or he went be good at. this maybe he'll be fantastic but that is his real test on saturday. >> henry, he's underscored his appeal to black and latino voters. first, how much is that true? and secondarily, is that going to get him anywhere? he's already indicated hey i wouldn't let what happened to bernie sanders happen to me with the black lives matter. >> oh i pray a black lives matter presence in iowa. i do. >> when we look at the polling he has absolutely no support among are african americans and latinos. and let's remember what skyrocketed him. it was wolf whistle, dog whistle. like i say now he's both wolf whistling and dog whistling. with regard to people of mexican descent. this is someone who's company has been sued by the department of justice for unwillingness to rent to african americans. he's a real problem for the republican party in that he is branding the republican party as the front runner. there is no question now no matter how you mark this, he leeds in iowa. he leads in new hampshire. he leads national among the republicans. he gets obliterated by the democratic front runner right now. hillary clinton beats him overwhelmingly. so badly that there is -- based on polling -- that since 1920 there has not been an election that would be so bad for a major party candidate. >> that's if hillary clinton -- >> and bernie sanders beats him too actually. >> let's be clear the democrat beats him. >> let's also be clear on one thing. donald trump is appealing more in a populous fashion. i don't think he's branding the republican party at all at this point. >> he's not polling any democrats or independents. >> he's not trying to be representative of the republican party. his image, everything he brings is i'm not a politician. i'm not really even part of the political class. >> but hes running republican. >> and cruz and bush and everyone else are running towards him to get the vote and that is the problem -- >> and things change and i really do not see him becoming the nominee, it will not be the donald trump republican. that is just not what you are going to see. >> he might be -- well look. jeb bush and mike huckabee both went after hillary clinton. are they overlooking bernie sanders? and is that a problem? >> that is interesting. they might be but i don't think they need to worry about bernie sanders right now. i'm not dismissing his candidacy but right now i think they want to jump on her with both feet and damage her so she loses the primary or is really wounded going into the general election. i think if bernie sanders pulls ahead in another state, i think they will be aiming at hillary clinton until she dropped out. >> and they are aiming at hillary because it is red meat in the republican primary. not necessarily because they are trying to hurt her i think down the road. >> it is a two for. >> right. it is popular, particularly in iowa to go after hillary. beth both the leading democratic candidates are basically fighting over issues. both have released very significant, very smart commencive plans. >> and no personal attacks against each other. >> but they both released plans, for instance, just recently to make college affordable. we're not saying these are personal attacks on the republican side. >> let me ask you about jeb bush, susan. why is he tanking? why is he not doing well? he's out of the top five in the poll there in iowa. what is going on? and what does he need to do to revamp his candidacy? >> i think the strategy is just to keep one foot in front of the other. be low key. not make any mistakes. still be out there answering question. he did do the soap box. he was subject to heckling. that was fine. he's answering questions from reporters. but he's going to do this on his time. the best bet he has is not to compete with trump. he's got let trump go through this -- >> bet on him self imploding -- >> yes in that way and that is why he is again i think purnly keeping as low key as possible. >> thank you so much for your time. still to come, marco rubio and jeb bush come out strong against president obama's iran deal. what they plan to do if elected. and animal loves are waiting with bated breath. it's so shiny. i know, mommy, but it's time to let the new kitchen get some sleep. if you want beautiful results, you know where to go - angie's list. now everyone can get highly rated service even without a membership. you can shop special offers or just tell us what you need, and we'll help you find a local company to take care of it. angie's list is there for all your projects, big and small. pretty. come see what the new angie's list can do for you. everyone is looking for ways while to cut expenses.s unique, and that's where pg&e's online business energy checkup tool can really help. you can use it to track your actual energy use. find rebates that make equipment upgrades more affordable. even develop a customized energy plan for your company. think of it as a way to take more control over your operating costs. and yet another energy saving opportunity from pg&e. find new ways to save energy and money with pg&e's business energy check-up. mr. trump, what is left in your life?

>> as you well know, reaching congress is quite a challenge, particularly when there are millions and millions of dollars being spent to give a message to try to defeat negotiations and defeat the bill. but what we do in the video is we make it very clear. many of the same people who said we absolutely must go to war with iraq, we must go to war them now, the same people are saying no negotiation, no deal. stop everything. and i for one, i mean, can you imagine if you had voted for the iraq war and now you are saying oh yeah, we -- forget about that. but let's make sure we don't have a deal with iran. i don't know how people can live with their conscience, frankly, with that kind of action. >> do you think president obama will be able to hold on to democratic support for the deal? chuck schumer of course famously dissents but do you think others will stick with him? >> i think they will. i think there are many members of congress in the senate and the house who are looking at the deal, who are paying attention to the reality. and who know that this is our best clans for peace. and as one of the members of the house said, it is the first time in years he's being given the opportunity to vote for peace. and we know taking on the military industrial complex around war/peace issues is tough. there is a huge invested lobby that financially profits and idealogically believes the only solution is more invasion, more militarization. but we have an amazing opportunity here and i am for one very optimist i. >> senator schumer also said the inspection regime in the first ten years is simply far too weak. what is your reaction to that? >> i -- i wish that he had read the piece of paper that talks about the inspections. it is hard for me to fathom how he can say that when you look at the piece of paper, when you see the details and which is -- this is the strongest, most intrusive with the most guarantees of inspections that we can do when we think it is the right time. that's never happened before. so it really mystifies mi how senator schumer came to that conclusion. >> you spoke earlier about the same people who were saying let's rush to war with iraq are the ones now who don't even want to have a conversation. what would a bush presidency look like? and how would it impact this kind of deal? >> well it is a terrifying thought. i mean, let's just pause for a minute. the number of lives that have been taken because of the iraq war. the deaths on americans and iraqis, the financial toll. to think that that might happen again with another bush and another war is something that i think many people no matter what their political bias or approach will be would really hesitate. because we're stilling paying an enormous price in lives and money and morality for the iraq war. and to think here we have this incredible opportunity. look, i've been very critical of the president obama on drones and critical of afghanistan. i'm thrilled there is an opportunity now to be supportive and say he's done something incredibly important. and it behooves every single one of us to call our senators, call members of the house and tell them act now for peace. protect the possibilities of peace. >> robert greenwald, thank you for joining us. coming up king james is taking his reign off the court and into the classroom. plus corn dogs and campaign speeches. the dems are heading to iowa for good old fashions fair food and fundraisi fundraising. ♪ no student's ever been the king of the campus on day one. but you're armed with a roomy new jansport backpack, a powerful new dell 2-in-1 laptop, and durable new stellar notebooks, so you're walking the halls with varsity level swagger. that's what we call that new gear feeling. you left this on the bus... get it at the place with the experts to get you the right gear. office depot officemax. gear up for school. gear up for great. i take prilosec otc each morning for my frequent heartburn. because it gives me... zero heartburn! prilosec otc. the number 1 doctor-recommended frequent heartburn medicine for 9 straight years. one pill each morning. 24 hours. zero heartburn. imagine - she won't have to or obsess about security. she'll log in with her smile. he'll have his very own personal assistant. and this guy won't just surf the web. he'll touch it. scribble on it. and share it. because these kids will grow up with windows 10. get started today. windows 10. a more human way to do. college education has become a big issue in the democratic race for the white house. hillary clinton announced a debt free plan for 350 billion over ten years. and bernie sanders wants to approve college education free across the board. the democrats are driving the conversation but at the same time some celebrities are trying to influence the debate as well. here is geist's interview with lebron james. >> lebron james just can't miss. >> and one. >> carrying the cavaliers to the nba finals in his return to cleveland. showing off his comedy chops in one of the hit movies of the summer. and on this day in ohio making a stunning pledge. through his charity, the lebron james family foundation, lebron vows to send qualifying students from his hometown to college on four year academic scholarships. >> at this rate we got 1100 kids in our program. if i can put 1100 kids into college, free, i've done something. >> as an akron teen himself, lebron skipped the awkward years and straight to the cover of sports illustrated where he was anointed at 17 the chosen one. >> are you able to look back now at age 30 and say that was a surreal experience?

he worked with them in the senate, they had a good relationship. what is the final analysis in terms of why he went to clinton? >> i think first of all he's a very thoughtful individual who wants to be behind a winner. and it is so unlikely that bernie sanders will be the party's nominee so it wouldn't make sense. and it was a very smart strategic move to have him do this letter right before she came in. i'll just take a little issue with something. which is she hasn't learned all her lessons about retail cam pains because she could do the soap box. >> do you think democrats will finally fore swear their inability to beat up on each other and take some shots tonight at the wing ding. >> will they throw wings at the wing ding? i think that the democrats have been very disciplined on this. i don't expect that to change. i think you will hear i think some push and pull on issues. this is not the republican primary. i don't expect to see the kind of equivalent of rand paul yelling at donald trump about how he's buying politicians and donald trump saying yeah i bought you. we're not going to see that. but we are i think going to see increasing tension around policy and who is going to do more for families and who is going to do more to address income inequality. we're starting to see that push particularly between the two leaders in the polls, between sanders and clinton. i anticipate we'll see more of that. i think that is only good. good for america, good for the party. and, you know, it will open some doors for people to maybe switch their votes. >> so susan, do you think secretary clint on is making a mistake by not speaking at the iowa state fair? >> i do. and this is part of her strategy all along is to have very careful, orchestrated events. put the press behind ropes and really not interact with too many people. i understand that given the situation and the week she's had why she probably doesn't want to do it. but she's got to show that she has the chops to just stand up there and do what needs to get done. and that is one of them. that is part of the ritual in iowa. you are talking about hard core people out there who really get into this and they want o see their candidate. >> henry there have been all kind of rumors about joe biden swirling around who or not he'll enter the race. some distant rumors of al gore chomping at the bit. what do you make of that? and do you think biden is looking at clinton's problems vis-a-vis the e-mails as an index as to whether or not he'll jump in? >> i'm not sure how much the e-mails move democratic primary voters. i haven't seen anything in the polling that indicates that. i do think that bernie sanders has demonstrated that there are votes out there for someone who is populist, someone who is talking about issues that effect working families and that is i think starting to create some interest in other candidates who are saying oh, well maybe hillary is not inevitable. but hillary has been very smart. in that she's come back with what are very, very aggressive plans like the one you mentioned earlier about making college affordable. so i expect this to be a fight. a fight around issues. i think that is only good. that will attract more people to these candidates and maybe it brings more candidates into the fold. maybe not. i think that this may be the field that we see going through. >> susan, do you think either biden or gore would be formidable challengers to secretary clinton right now. >> i don't think that gore would. i think biden certainly would be. because he takes away her narrative for running, in essence. why wouldn't you go with the vice president? and i don't have all of these problems and i didn't do all of these self inflictive wounds. so people are worried. >> thank you so much. next movie theaters showing the movie "straight out of compton are beefing up security this weekend. if you have moderate to severe plaque psoriasis. isn't it time to let the real you shine through?

dismount! oh, and he sticks the landing! a year in hawaii sounds great, doesn't it? what about a year in hawaii inside a solar-powered dome on top of a mountain with five other people? six scientists are going to do it for the sake of space exploration with the goal of going to mars and back. the group will begin their time in the hawaii space exploration analog and simulation or hi-seas on august 28th. it will be the fourth and longest mission yet. hi-seas researchers are working to obtain support strategies for traveling to mars. the trip is estimated to take three years. joining me now is captain mark kelly, retired nasa astronaut and shuttle commander. what are the greatest research benefits of doing a simulation like this, although i must admit being in mars via hawaii is great for a year. >> well, so you know, you got to put it all into context with all the mars research that we currently do. you know, we send probes to mars to do science now. we have my brother on the international space station spending a year running the u.s. laboratory and the space station itself but also seeing the effects of long-term space flight on the human body but one of the big challenges for going to mars is how do all these people work together in tight close quarters for a long period of time? and how do you supply them? where do they get their food from? can you grow food in space? we saw that we can do that. it was just done on the international space station. these are complex issues. but really having six people working very close together in a small environment for a long period of time presents a lot of challenges. >> that simulation makes sense and also makes sense to talk to somebody who has been there, and you have. you've logged 54 days in space during four missions. how does space travel affect you physically and mentally? >> well, the physical effects are pretty significant. i mean, you lose blood volume, your immune system gets depressed. you start to lose bone mass after spending some time in space. we have astronauts that have had issues with their optic nerves. then there's the radiation environment. so it has significant physiological effects, and we study those things on astronauts in space. and these folks that are sitting in on mauna loa in hawaii for a year -- you know a year is a long time to be in any one given place, i don't care where it is. they'll have a big challenge ahead of them. >> these crew members are on a mountain on hawaii after all, but what can they expect when it comes to being in isolation for this length of time? you've already indicated that it's tough. what are some of the challenges of being in one space and one time that long? >> you know one of the big things is can people get along? i'm here in tucson. and in tucson we have biosphere two which was not really a nasa project but there were eight people that were put in the relatively small environment, much bigger than what is on mauna loa, and they started to quickly have interpersonal problems. we've seen it on the space station as well or in the close quarters of a space shuttle. when you're going to mars, there's no turning back and replacing one crew with another. we have to come up with strategies on how do we mitigate against these interpersonal issues and how do we work together effectively as a team in a really harsh environment? >> it gives new meaning to lord of the flies or fliers -- >> let's hope not. >> absolutely. so your brother, you mentioned him, captain scott kelly is spending a year on the international space station right now. he's been tweeting. how is he doing? >> he's doing good. i not only see his tweets, but i can talk to him on the phone rather regularly. you can't call up to the space station but a crew member on board can call down. so i talk to him probably every other day or so. he's doing really well. >> the two of you are being studied as part of this process. how do you feel being part of a study that could have a huge impact on the future of space travel and tell us why you're being studied together. >> we're identical twins. he is spending a lot of time in space right now. i'm on the ground. there's stuff that's unique to twins that really helps with the scientific research, so there's about ten universities around the country and even in some other countries that are looking very closely at us, the effects of the radiation and the zero gravity. i'm kind of the guinea pig on the ground. you know, he's the guinea pig in space. and we're going to learn a lot. and we need to know a lot more about the effects on the human body. if we're going to could that, like you mention, a three-year trip potentially to go to mars with crew members and bring them back and that's a long time. >> despite what happened to george clooney in that film, tell us, do you have any desire to go to mars? >> i'd love to go to mars. i think the first person that's going to walk on mars is alive today. it could very well be some kid somewhere in middle school. it could be somebody who is more middle aged. we're going to have to see how fast we can get there. the important part -- there's a lot we need to learn, but really what we need is the public's support for making a human -- you know a mission to mars with people. we need the public behind it. i think it would be a great thing to do. i'm a strong advocate of it and i'd love to be able to go given the opportunity. >> it could be a guy that has a twin, too. he might be in line for that as well. >> may be. >> thank you for your time tonight. >> you're welcome. >> i'm michael eric dyson.
