In 90 seconds. 90 minute format, not 20 second sound bites, a real opportunity to hear somebody Say Something and get into is that tra actually true or not. The candidates prep for the debates. Donald trump has been out campaigning like regular. How has he been preparing for the debate. Donald trump has been preparing for this debate for his entire lifetime. Sporting world lost a legend, the passing of famed golfer Arnold Palmer. If youre playing today, would you be number one . I cant answer that. Youd like to give it a shot, wouldnt you . Youre right. Police say that officers shot a gunman who opened fire near a Shopping Center in houston. We know hes been neutralized, no longer a threat to the public. The suspected gunman accused of killing five people at a mall in washington state. I dont know what his motivation was to do this. Star pitcher Jose Fernandez was killed in a boating accident. The pride of cuba with a dazzling right arm. The passion he felt about playing, thats what i think about. In canada. High fived the prime minister. Over the middle, dez bryant, touchdown, cowboys. Jerry with a big smile on his face. 3117, dallas. Deep left field. Would you believe a home run . Veiin, we love you, this is r you, my friend. And all that matters. Sunday morning hangover wont be the same without you. Charles osgood. We thank you for everything. Well see you on the radio. See you on the radio. See you on the radio. On cbs this morning. I will see you on the radio. I want to thank you all, the wonderful audience, and i also want to thank all these people. This mornings eye opener is presented by toyota, lets go places. Welcome to cbs this morning. The first president ial debate tonight is likely to be the most watched in history. Hillary clinton and donald trump will face each other in primetime for 90 minutes. The Television Audience could be 100 Million People or more. The latest National Poll out this morning shows the race is tied at 46 . Clinton led by 6 points in the same Bloomberg Politics poll after the convention. Key advisers for both candidates will be here in studio 57. Well talk to trump Senior Communications adviser jason miller and robbie mook. First, Major Garrett and nancy cordes are at hofstra university, the site of tonights debate. Major is covering how trump is getting ready. Good morning. Good morning. This whole scene here today, tonight will remind the country powerfully of how improbable all of this once was. Donald trump, pure novice, in the ultimate political ring with Hillary Clinton. Statistically tide for the presidency of the United States. Trumps preparations far more nonchalant than clintons. A daring calculation, one that if successful could catapult his candidacy and if not might well crater it. Trump is doing great. Hes being himself. Mr. Trump is ready for the debate. Hes very excited. Donald trumps surrogates glossed over the light debate 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. Trump has held no mock debates and devoted little time to briefing books. His recent policy speeches have all been on teleprompter. A crutch he will not have against Hillary Clinton. House Speaker Paul Ryan sounded a cautionary note. Hillary clintons been doing this most her life. She is the consummate pro. This is new for donald. So i think he should obviously overprepare for it. Leading up to the debate, trump pledged to spend 140 million on tv and Digital Advertising between now and election day. Ten times his budget so far. The 100 million tv investment first reported by cbs news will finance ads in 13 states including three states trump added because of tightening poll numbers. Wisconsin, new mexico, and maine. Another predebate development donald, youre a sniffling coward. Ted cruz buried the hatchet and formally endorsed trump, citing the need to protect future Supreme Court vacancies from clinton. There is also predebate high jinks, Clintons Campaign invited brash billionaire and trump critic mark cuban to the debate as her guest. Trump returned the psychological warfare suggesting he will put Gennifer Flowers right alongside of had him. Quick refresher, flowers revealed a decades long affair with bill clinton when he ran for the presidency in 1992. The Campaign Says she has not been formally invited and they dont expect flowers to attend. Thank you very much, major. Nancy cordes is inside the debate arena, tracking Hillary Clintons preparations. Good morning. Good morning. The clinton camp believes tonights debate will be so pivotal that she did just two Public Events all of last week, compared to the nine events that her opponent did. And they say shes been prepping for a debate that will show that 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 podesta, debate guru ron klain and philippe rinus who made him a Natural Choice to play trump. Clinton studies trumps primary debates to see how opponents knocked him off stride. Had her campaign is trying to get under his skin by releasing a list of 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 that trump needs to be held to the same standard as clinton had it comes to specifics. I think the great virtue of the debates is you get 90 minutes to look at people and really see whether there is depth, whether there is substance. And whether there is candor and truthfulness in what they say. When youre practicing law clinton knows the format. Shes 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 virginia and down to 1 point in colorado. Two states where her campaign was so confident a month and a half ago, they stopped airing tv ads. And thats why clintons aides say her job tonight is to convince a wide swath of voters that trump lacks detailed policy proposals and is easily provoked. To that end, charlie, you might hear her talk about his admiration of putin or even question whether trump is worth as much as he says he is. Robbie mook is here. Is the goal tonight to tear trump down or build her up and get at the question of trust and command of issues . Im really glad you asked that. Hillary clinton does know she needs to earn the voters trust. We found these unfiltered moments as tim kaine said, 90 minutes up there, she can speak directly to the voters, she had the opportunity to talk about make a difference in peoples lives, but how this campaign is really a part of a Lifelong Mission to fight for kids and families, shes done really well. I think it is an outstanding question, will trump demonstrate a command of the issues and we think thats a bar every candidate needs passed. We also are concerned that trump is going to continue to lie. And thats why do you think she can change the trust dynamic in one debate when 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 fight on the side of everyday people and it actually has plans that will make a difference in their lives. Can they can voters trust a candidate to get that done . And they can absolutely trust hillary. She has a lifetime record of working with both sides of the aisle, bringing people together and getting real things done. We keep hearing shes preparing for two trumps. What exactly does that mean . Tell us a little bit about the preparation work you all have been doing. One of the concerns that voters have about donald trump is that he doesnt have the right temperament to be commander in chief. He is erratic. We dont know whether trump is going to show up to try to have a serious discussion of the issues or whether hes going to bully. We have seen him bullying hillary with mean tweets the last few days. We just dont know who will be there. Mark cuban in the front row, who has been very vocally against donald trump, is that a little bit of a dig to say to call him out . That was not the intent. Both sides invite their supporters to come, were really proud to have the support of mark cuban who came off the sidelines, hes not political. Hes a businessman. Has a lot of experience creating jobs. Were very proud to have a sport hes been outspoken and excited to have him there. He represents the kind of people that are coming to the campaign. Republicans, republican leading independents who are concerned about Donald Trumps temperament. To follow on what gayle said, is that an early indication inviting mark cuban that part of the strategy is to provoke donald trump tonight, to get under his skin . You know, again, were really focused on this opportunity that hillary has to speak directly to the voters on the issues. But we are concerned that donald trump may lie. He may throw information out there and hillary will have to spend all of her time trying to correct the record rather than talking about the things she wants to. What do you expect the moderator do . We ask the record be checked. If donald trump lies, which hes done in the past, that that be checked. One question about the surge that donald trump is experiencing, this is a dead even. You said the race will tighten. Nobody thought it would be dead even at this moment. Well, first of all, i take there is a surge. I take these public polls with a grain of salt. Were seeing something slightly different on our side. But, you know, operationally it doesnt matter. We should be running like were 20 points behind, this is the most important election in our history. It is certainly in our lifetime. We should be all in and we should try to win by the biggest margin we can. Thank you. Thank you. In our next hour, well go inside Donald Trumps preparations with the Senior Communications adviser jason miller. Thats ahead. There has been 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 theyre going to do this. I dont think it is a good idea to get the moderator into essentially serving as the encyclopedia britannica. I think it is better for the person to facilitate and to depend on the candidates to basically correct each other as they see fit. Cbs news political director John Dickerson and cbs news contributor Bob Schieffer have moderated many debates. Theyre here with perspective on tonights faceoff. Good morning. Let me ask you, bob, since you were involved in the last campaigns president ial debates, what about janet brown just said . Is it the responsibility of the candidates to fact check each other . Yes. I think the 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. Thats called a rebuttal. If they dont, i think the moderator has to step in and say, you know, for the record, folks, and take it from there. Maybe ask another question. There are a lot of there is talk that a lot of voters have still not made up their minds tonight. What are they looking for . What should each candidate do to try to get those voters on their side . It depends. They have two different basically donald trump has to show that he can be president and debate is the most formal thing we have 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, it is basically to present Something Different than the candidate who shows up at his rally. For Hillary Clinton, she has to remind people of donald trump, show something from her heart, which is for undecided voters and for her voters. We know people become stronger partisans when they watch debates. If Hillary Clinton has enthusiasm problem, which some of the polls show she does and enthusiasm is different than vote intent, people may be ready to vote, may not just be excited about it. If she has an enthusiasm problem, then a debate can make people think, thats why i like her. You think this is more about shoring up your base than it is about reaching an undecided . It can be both. Undecided may slosh around over the course of three different debates, but there is voting going on now. If both campaigns can grab their voters who get newly energized and bank votes, get them, you know, in line so there is an organizational benefit. In fact, the campaign believes that 40 of the final tally may be by early votes this year. To your point. Thats why the debates are so critical. Not that youll remember going to vote. People are voting now. Thats why when we talk about facts and all of 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 a time of crisis. Therefore, what does donald trump have to do and how does he 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 not a question of what he might do, but what does he have to do . How do you appear president ial . Appears president ial as someone suggested, does he become somber and therefore less attractive . I think he has to just lead the impression he could handle the job. Now, how he goes about that, i have no is that a pretty low bar . Thats what i think is the what people decide during these debates. Do you think theyre being judged differently, Hillary Clinton and donald trump, the clinton Campaign Says that she is being held to a much higher standard than he. I dont think so. I think theyre both judged by exactly the same standards and well see what happens, how they decide what the standards are. You both know this impression will be made in the first ten or 15 minutes. Thats right. Because of twitter. So what is happening is a lot of a lot of reporters will be wasting their time looking at twitter instead of the 90 minutes and develop a narrative and that will start bouncing around and we see that in the last campaign. And thats not good. 90 minutes and no breaks. All right. Thank you, both. Bob schieffer and John Dickerson. You can watch the debate tonight here on cbs. Our live coverage begins at 6 00 pacific time. The world is remembering the extraordinary career and life of Arnold Palmer, the golfing great 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 looks at his lasting legacy. Beloved and transcendent, thats how hes being remembered today. His father, a golf pro and grounds keeper in latrobe, pennsylvania, taught palmer the game that he then helped introduce to millions. Voted the athlete of the decade in the 60s, he was always true to his fathers words, dont tell people how good you are, show them. The line is perfect. Hes got it. Known simply as the king, Arnold Palmer captivated the sports world with his ferocious style of play and the magnetism of a movie star. Golf would never be the same when he burst on the scene in the late 1950s. He became the face of the sport and helped turn the Country Club Game mainstream. In all, palmer won seven major titles including four masters, tallying 62 pga tour wins. He was courted by president s and spawned a rabid following of fans dubbed arnies army. There goes the gallery. Look at them race for positions. Palmers high risk, high reward approach ratcheted up the drama of the game. And this fellow is still hunting birdies. In 2011, he spoke to charlie rose. There is no game like it. You go out there, you tee it up on first tee, charlie. Yes. It is you. A golf ball and the golf course. And there you go. Palmer with a pioneer in marketing for athletes and paved the way for future stars. There is even a drink named after him. He also received the president ial medal of freedom and congressional gold medal. The battle between palmer and Jack Nicklaus defined rivalry and though nicklaus came out ahead most times, palmer says even the losses helped shape him. They really hurt. But when i reflect on it now, and i look back, and say it taught me something, 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 always had my back and i always had his. He was the king of our sport and always will be. And bob hope may have put it best, he said in bringing golf to the masses, two things mattered, Arnold Palmer and the mulligan. There
