Major garrett is covering how reporter good morning. This whole scene here today, tonight, will remind the coun powerfully how this once was. Donald trump in the ring with Hillary Clinton. Statistically tied for the presidency of the united states. A daring calculation, one that if successful, could catapult his candidacy and, if not, might well crater it. Trump is doing great. Mr. Trump is ready for the debate. He is very expedited. Reporter donald trump surrogates went over the prep and suggested a life of real estate and reality tv may be enough. I think donald trump has been preparing for this debate for his entire lifetime. Reporter trump has held no mock debates and devoted little time to briefing books. His recent policy speeches have all been on teleprompter, a Hillary Clinton. House Speaker Paul Ryan sounded a cautionary note. Hillary clinton has been doing this much of her life and a consummate pro and new for donald so i think he should overprepare for it. Reporter leading up to the debate trump spend 140 million on tv and digits ads. Ten times his budget so far. The 100 Million Dollar tv investment first reported on by cbs news will finance ads in 13 states. Including three states trump added because of tightenpo wisconsin, new mexico, and maine.

Clintons campaign invited brash billionaire and trump crick mark guest. Trump returned the favor and said he would put Gennifer Flowers alongside of him. She said she had a decades long affair with clinton. Trump said she has not been formally invited and, gayle, they dont expect her to attend. Nancy cordes is inside the debate arena tracking Hillary Clintons preparation. Nancy, good morning. Reporter good morning. The clinton camp believes tonights debate will be so pivotal she did events all of last week, compared to the nine events that her opponent did and they say she has been prepping for a debate that will show she knows the issues and trump doesnt. Clinton spent most of the weekend at home and at a nearby hotel, practicing with a small group of confidants, including Campaign Chairman john poe ddes pmpltse. Clinton has studied debates. Her campaign is trying to get under his skin by releasing a list what they call the seven deadly lies he might tell tonight, like his claim that he opposed the iraq war from the beginning. Or that hell get mexico to pay for a border wall. On face the nation, clintons running mate argued trump needs to be held to the same standard as clinton when it comes to i think the great virtue of these debates you get 90 minutes to look at people and really see what whether there is depth, whether there is substance and whether there is a candor and truthfulness in what they say. Reporter clinton knows the format. She has participated in 26 president ial primary debates and needs a performance tonight that will stop her slide in the polls. The latest cbs news Battleground Tracker shows her lead has shrunk from 12 points to 8 in colorado, two states where her campaign was so confident a month and a half ago, they stopped airing tv ads. And that is why clintons aides say cher job tonight is to convince a wide swath of voters that trump lacks detailed policy proposals and is easily provoked. To that end, you might hear her talk about his admiration of putin or even question whether trump is worth as much as he says he. Robbie mook is here. Good morning. Good morning. Is a goal tonight to tear trump down or build her up and get at the question of trust, and command of issues . Im really glad that you asked that because Hillary Clinton knows she needs to earn the voters trust. We have found the unfiltered moments as tim kaine said 90 minutes up there she can speak directly to the voters and had the opportunity to talk about not just what her plans are to lives but how this campaign is really a part of a Lifelong Mission to fight for kids and families. She has done really well. I think it is will trump demonstrate a command of the issues . We think that is a bar every candidate needs to pass. We also are concerned that trump is going to continue to lie. Why do you think she can change the trust dynamic in one debate when, in fact, she hasnt been able to do it over a lifetime or in terms of this campaign . The central question of this entire campaign is which one of these candidates is going to t people and it actually has plans will make a difference in their lives. Can voters trust a candidate to get that done . And they can absolutely trust hillary at the she has a lifetime record of working with bojed of the aisle, bringing people together and getting real things done. We keep hearing she is preparing for two trumps. What exactly does that mean . Tell us a little bit about the preparation work you all have been doing. Well, one of the concerns that voters have about donald right trempmeemperament to be commander in chief. We have seen him bullying hillary with mean tweets the last feud. Few days. We dont know who will be there. But hillary will be prepared. In the front row who has been very vocal against donald trump is that a little while of a dig to call him out putting mark cuban on the front that was not the intent. Both sides invite their supporters to come and we are proud to have mark cuban who came off the sidelines and he is political and has a lot of experience creating jobs. We are excited to have him there and have his support. He represents the kind of people coming to this campaign, republicans, republican leaning independents who are concerned about Donald Trumps temperament. Was that an early indication inviting mark cuban that part of under his skin . Again, we are really focused on this opportunity that hillary has to speak directly to the voters on the issues. But but we are concerned that donald trump may lie, he may throw misinformation out there and that hillary will have to spend all of her time trying to correct the record rather talking about the things she wants to. What do you expect the moderator to do . All we are asking is the record be checked. If donald trump lies, which he has repeatedly done in the past that that be simply ke trump is experiencing this is a dead even heat. I know you have said the race would tighten but nobody thought it would be dead even at this point in time or a surge . I take thats public polls with a grain of salt. Operationally, it doesnt matter. We should be running like we are 20 points behind and this is the lifetimes and we should be all in and win by the biggest margin we can. Thank you, robbie mook. Next hour, we go inside the donald trump preparation with jason miller. A lot of talk about whether the debate moderator should also be a fact checker. The executive director of the commission on president ial debates doesnt want that. Commission asks independent smart journalists to be the moderators and we let them decide how they are going to do this. I dont think its a good idea to get the moderator in as serving as the britannica and i think its important to facilitate and ask the candidates to correct each other as they see fit. Cbs news political director John Dickerson and Bob Schieffer on here on some of this mornings faceoffs. Bob, you were involved in the last campaigns president ial race, what about janet brown just said . Is it the responsibility . I know youve written about this. The candidates to factcheck i think youre being unfair to both candidates if one of them makes a glaring error to not let the other person have an opportunity to call them out. I think people want to know if that person knows the answer to the question. That is a good thing. Its called a rebuttal. If they dont, then i think the moderator has to step in and say, you know, for the record, folks, take it from there. Maybe ask another question. There has been talk that a lot of voters have still not made up their minds, john, tonight. What are they looking for a what should each candidate to do to try to get those voters on their side . It depends. Basically, donald trump has to show that he can be president. A debate is the formal thing in a campaign where a candidate looks a little bit like a president and there is a style and so, you know, for donald trump, its basically to present Something Different than the candidate who shows up at his rallies. For Hillary Clinton, she has a bunch of things. She to remind people of the to show something from her heart, which is both for those undecided voters but its also for her voters. What we know from Political Science about debates is that people become stronger partisans when they watch debates. In Hillary Clinton hasnt enthusiasm problem and that is different than vote intent. In other words, people may be ready to vote but may not be excited about it. If she has an enthusiasm problem, then a debate can make people think, oh, that is why i like her. You think this is more about shoring up your base than it is ou it can be both. Undecided may slosh around over the course of three debates but voting going on now. If both of your campaigns can grab voters that are newly energized by something happens in a debate and bank votes and get them in line so there is an organizational benefit. In fact, the campaigns believe that 40 of the final tally may be by early vote this year. To your point. That is why these debates are so critical. Its not that youll remember going into the booth but people are voting now. That, these debates are about so much more. Than somebodys position on the issues. Voters want to take a measure of the person. Does a person have the right stuff . Does he have the dignity, the courage, how you react under pressure. I think the reason most people vote for a president is do they think this is someone that they would feel comfortable with in time of crisis. Therefore, whats do it . It will be interesting to see. I mean, i have no idea what donald trump is going to do. And anybody that wants to predict what donald trump is going to do its not a question of what might do but what does he have to do . In other words, how do you appear president ial . Does he become somber and less attractive . I think he has to just leave the impression that he could handle the job. Isnt that pretty low bar . Well, but thats what i think is what people decide during these debates. Do you think they are being judged differently, Hillary Clinton and donald trump . The Clinton Campaign says that she is being held to a much higher standard than he. No, i dont think so. I think they are both judged by exactly the same standards and we will see what happens. How they decide what the standards are that they are trying to meet. Impressions will be made in the first 10 or 15 minutes . Ha because of twitter. What is happening a lot of reporters will be wasting their time looking at twitter instead of the whole 90 minutes and they will develop a narrative and that narrative will start bouncing around and we saw that in the last campaign and that is not good. Yeah. 90 minutes and no breaks. All right. Thank you both. Bob schieffer and John Dickerson. Watch tonights debate on cbs. Our live coverage begins at 9 00 eastern 8 00 central. The world is remember the extraordinary career and life of died yesterday from heart complications at the age of 87. Palmers style and dominance on the golf course elevated the game to new heights. Dana jacobson has more. Reporter beloved and transcendent is how Arnold Palmer is remembered today. His father a golfer and grounds keeper in latrobe, pennsylvania, introduced him to the game that he introduced to millions. Voted the athlete of the decades in the 60s, palmer was always true to his fathers words. Donth are show them the line is perfect. Hes got it reporter Norah Odonnell known simply as the king, Arnold Palmer captivated the sports world with his ferocious style of play and magnetism of a movie star.

Including four masters and ta tallying 62 pga tours wins and court by president s and had a rabid fans dubbed palmers army. His approach ratcheted up the drama of the game. And this fellow is still hunting birdies. In 2011 he spoke to to charlie rose. There is no game like it. You go out there and you tee it yes. Its you. A golf ball and the golf course. And there you go. Reporter palmer was a pioneer in marketing for athletes and paved the way for future stars and even a drink named after him. He also received the president ial medal of freedom and congressional gold medal. The battles between palmer and Jack Nicklaus defined rivalry and though nicklaus came out losses helped shaped him. They really hurt, but when i reflect on it now and i look back and i say, it taught me something. It taught me how to live and how to be a better guy and not let it defeat, be the end of my life. And im thankful for that. In a Statement Last night, his long time friend and rival Jack Nicklaus said we were great competitors who loved competing against each other but we were always great friends along the way. Arnold had b had his. He was the king of our sport. And uls will be and bob hope may have put it best. He said in bringing golf to the masses, two things matter Arnold Palmer and the mulligan.
