They do that paubecause of the pandemic knowing millions of americans plan to mail in their ballots this year and since it will take time to count all those ballots there is a very good chance we wont know the winner of the election on Election Night. Well take a look at what may happen here in this hour ahead for you. Make sure you stay tuned. Joining me now cnn White House Correspondent john harwood and mrs. The senior political reporter for politico florida. Good evening to both of you gentlemen. So happy to have you on. Hope you had a great labor day weekend. John, lets start with you. We have seen clashes between Trump Supporters and protesters recently and tonight as the campaign really kicks off now heres what the president is saying. Watch those ballots. I dont like it. You know you have a democrat governor, all these democrats watching that stuff. I dont like it. Watch it. Be poll watchers when you go there. Watch all the thieving and stealing and robbing they do. This is important. We win North Carolina we win so this is not really hard to see how this could get volatile here and create an atmosphere of intimidation at a time there is already a ton of concern about voter suppression. What do you think, john . I agree with you, don. Look, you can hear in the president s tone of voice that he was acting. That was performance schtick he was doing for the crowd. But all of that schtick has gotten increasingly raw both in terms of protests in the cities talking about anarchists and people who are going to, you know, threaten your physical safety, talking about suburbs getting demolished, talking about thieving and robbing at polling places. You could see just as he has encouraged that sort of vigilante activity in the streets that we saw acrocost th lives of two people in kenosha and one of the vigilantes and later the person who shot him in oregon, you could see that kind of disorder occurring on election day. And together with the president s suggestion that people who have already sent in absentee ballots going to their polling places to see if their ballots have been cast and of course in some cases the ballots would not have been recorded because they may not have been received and marked in the poll book when people show up you could see him setting the stage for real chaos at polling places consistent with his statements that, well, it is going to be a rigged election and that is the only way i can lose trying to cast doubt over the legitimacy of the electoral process and also perhaps the administration of the electoral process. Mark, lets bring you in. Ill put up this new poll out today showing trump and biden tied in the battleground state of florida. You say this race is much close thaern people think. What do you hear from florida voters . Well, probably hearing what your poll or the marist poll you are featuring is showing. It depends on who you talk to. This kind of state where you can go say into southwest florida which is blood red republican country and you would ever wonder why joe biden would have a chance but then you could wind up in Broward County and wonder how on earth it could be that President Trump would get any votes in florida. Were pretty evenly divided, certainly on this question, for sometime, biden has been leading marginally, that is within the margin of error on the polls but they appear to be tightening up, they feel to be tightening up. Florida is one of those states that you kind of flip a coin and it can wind up on its edge. That is usually how close our elections come. 2018 we had two top of the ticket races. Actually three top of the ticket races that were decided by half a point or less. Id be really surprised if anyone either biden or trump won by two points or more here. My goodness. Lets talk more about this poll. It shows trump leading among latino voters in florida with 50 support. Biden has 46 . But in 2016 in the exit polls it showed that Hillary Clinton had 62 support of latino voters in florida. How worried should the Biden Campaign be about this . Well, they shouldnt be that worried about that poll when it comes to latino voters. Understand about 17 of the registered voters in the state are hispanic. About 15 of the actual votes probably going to be cast by people who classify themselves as hispanic. That poll there has fewer than 150, 180 latino respondents. The margin of error is all over the place. A pretty big sample size poll out last week showed joe biden up by about 17 points. That is pretty good. It sounds pretty good. Its probably not good enough if he wants to win the state and it is still worse than Hillary Clinton did. That having been said, while joe biden appears to be under performing with hispanic voters relative to Hillary Clinton he is over performing with Nonhispanic White voters that is still the super majority in the state. For every hispanic vote he loses, quoteunquote, and joe biden picks up with white voters, he is making up a net of about four votes so that is a pretty good deal so far. I would urge everyone to understand these are polls. Theyre snapshots in time. They have margins of error. The smartest and dumbest things said in politics is its all about turnout and well see what happens on election day. It could be so close it might take a few extra hours or days to declare the winner but florida will have probably at least 75 of the vote in before election day both cast by absentee ballots in the mail or inperson early votes. Well probably have a pretty good idea who the leader is but it could be so close people have to be a little patient and we in the news media have to be cautious about declaring who the winner is on Election Night. People are going no its everybody watching the show who is they dont want that to happen. Mark, we thank you. John, well see you soon. Thanks so much. I want to get to general wesley clark the former nato allied commander. Thank you so much for joining us this evening. President trump is claiming that he rebuilt the u. S. Military at his rally tonight. Claiming that he rebuilt the military. It is one of his go to campaign lines but very different from what we heard from him just yesterday. Watch this. Im not saying the military is in love with me. The soldiers are. The top people in the pentagon probably arent because they want to do nothing but fight wars so that all of those Wonderful Companies that make the bombs and the planes and make Everything Else stay happy. Thats got to be galling to leaders who have dedicated their lives to protecting this country. Why is he saying that . Well, he is saying it as, just to attack an elite that he considers he is trying to reach beyond the commanders and get to the level of the soldiers and the junior leaders i guess. Its also part of the incoherence that comes out of Donald Trumps mouth. Maybe he thinks if he were a general what hed be worried about is how to make money as a general. He doesnt understand the first thing about the ethics of the United States armed forces. The ethics of the armed forces are about accepting responsibility, being competent, caring for others. He doesnt do any of that as a leader and i will tell you that hes making a big mistake saying that he rebuilt the armed forces, because they were there before he was elected and the people who were in it are highly offended and im not talking about top brass. Im talking about people in the middle. People near the bottom who came in under obama. They worked. They went to war. They suffered. Donald trump didnt change that. The pentagon always is looking to have more money for research and development and so forth. Because we are now reordering against china and russia but he didnt transform the military and they are deeply offended that he says that. I will tell you that some of the middle range officers see him for what he is. They know he doesnt represent their values. He is the antithesis of everything they stand for. Rather than duty, honor, country they say he stands for lie, brag, and blame. Wow. Thats his methodology. Hes got it exactly wrong. Hes treated with respect by the senior generals around whom he works and who give him policy proposals. They may not like it but further down i think hes really lost the respect of the men and women in uniform. Lets talk about this a bit more, because the president , general, he can claim the reporting first detail in the atlantic is fake. He can do that all he wants, but the tape doesnt lie. Listen to candidate trump talking about military leaders announcing their intention to attack isis. Whatever happened to the element of surprise . The element of surprise. What a group of losers we have. We have a bunch of babies running our country, folks. We have a bunch of losers. Theyre losers. Theyre babies. And so, you know, when you hear that and you hear the president say ive never called anybody a loser. I havent done that and then he is doing it on tape, clearly criticizing leadership then. Didnt stick, right, in 2016. But this time he called those killed action losers and suckers. The people who were killed action. Will this time be different . Well, i dont know. I think that in 2016 he still had a certain aura he brought in from tv. I think now he owns it. You know when youre a Company Commander in the United States army, you get a couple weeks, maybe 30 days, and then everything in that unit belongs to you. When youre the president of the United States if theyre looking at you and four years later youre still blaming your predecessor, uhhuh. Its your problem. They know he treats people this way. They know he says these things. People in the middle, this has gone through the armed forces. The Jeff Goldberg story, that came out because it was widely talked about by many people in the armed forces that he had insulted those who had served and suffered and died. You were aware before the reporting . Yes. This is something thats been going through the ranks im told and people have this is what happens when a man has the characteristics of the entertainer that donald trump has and he shoots off his mouth and says a million things and says things in public and in private. Look, if youre president of the United States you owe the deepest respect and gratitude for these men and women in uniform. Theyre putting their lives on the line and theyre trusting and their families are trusting you to make those decisions. And that is the way its been since we fought the revolutionary war. Its been tough. Some of the decisions that are made arent good. It is a sacred duty of the president to respect these people and their sacrifices and he hasnt done it and they know it. Its going to get worse and he is going to lose more and more respect as this Election Campaign continues. Thats his big concern, and it was just mind boggling to me to hear him say, only an animal would Say Something like that, and then someone plays a tape of him saying the exact same sort of thing in the next breath. Unbelievable. General as always thank you for your service and for appearing. Thanks. Millions of students across the country going back to school today but a whole lot of them will only be learning online. Coronavirus and administrations handling of the crisis will be a huge issue this fall. Where america stands on that as the Campaign Heats up. Thats next. Why . ahhhh incoming ahhhahh im saved water tastes like, water. So we fixed it. Mio and ask your doctor about biktarvy.

The president has been out in the field talking about a possible Coronavirus Vaccine before the election. Tonight we got the news drug Company Astrazeneca is pausing its vaccine trial due to an unexplained illness in a participant. It is one of the three in late stage phase three trials in the u. S. That as kids across the country face a whole new reality in the era of the coronavirus. Here is cnns nick watt. Reporter millions of students back in school today but most arent actually in school. Theyre online only. If you are in the red zone you really have to be very careful before you bring the children back because you dont want to create a situation where you have a hyperspreading event as you might have in the school. Reporter hartford, connecticut planned a hybrid model but a cyber attack forced a delay. As difficult as that was in this year when so much work has gone into preparing for the first day of school. Reporter tens of thousands of confirmed cases now at colleges. West Virginia University just suspended nearly all inperson teaching at one campus for two weeks. Friday night a covid positive frat member told to isolate went to a party anyway. Nationally case counts are still headed in the right direction. For now. But we are beginning to do things we havent done since the start of the pandemic. Reporter like opening some schools and colleges and moving indoors in colder weather. In new york, sheriffs deputies will now stop buses arriving from a staggering 33 states and territories. They will be pulling over buses before they arrive and theyll be giving out those Traveler Health forms to get people right away to sign up so we can make sure they quarantine. Reporter 11 states are right now seeing a rise in average case counts. Arizona and florida, Success Stories of the late summer ticking up again. We need to hang in there together. This will end. And it will end even sooner if we continue to go by the Public Health measures that have been recommended time and again for so many months. Reporter a new study of cell phone data suggests people staying home in the spring did slow the spread of the virus. They saved lives. But the president thinks shutdowns are ridiculous, claims democrats are using them just to hurt him. Weve got to regain the trust of the community. Reporter so the ceos of Nine Pharma Companies racing to produce a vaccine just signed a pledge that they wont submit too soon for approval, suggesting they wont bow to any political pressure. They hope to help ensure Public Confidence in the rigorous, scientific, and regulatory process. It is an unprecedented moment, an historic pledge. We saw it was critical to come out and reiterate our commitment that we will develop our products, our vaccines using the highest ethical standards. Reporter nick watt, cnn, los angeles. Thank you very much, nick watt. I want to bring in the director of the Global Health program at the council of foreign relations. Also the author of the plagues and paradox of progress. Good to have you here. Lets start with this new development with astrazeneca pausing its vaccine trials after a British Volunteer got sick. What does this mean for this vaccine and others Going Forward . Well, for this particular vaccine we dont know. It means delay for certain. There will be an investigation to identify whether this severe, adverse event was related to the vaccine or just something that happens when you have 30,000 people youre watching. So that will be delayed. What it does suggest is the risks that are inherent to Vaccine Development and the importance of conducting these trials to their conclusion. The president is pushing the timeline for a vaccine again tonight. Lets listen to this. Were producing a vaccine in record time. This is a vaccine that well have very soon, very, very soon. By the end of the year but much sooner than that, perhaps. But this was just this afternoon. This is dr. Anthony fauci, what he said about a vaccine before election day. Watch this. I think thats unlikely. I mean, the only way you can see that scenario come true is that there are so many infections in the Clinical Trial sites that you get an efficacy answer sooner than you would have projected. Like i said, it is not impossible, but it is unlikely that well have a definitive answer at that time. More likely by the end of the year. So, tom, the question is, what does this do to the confidence in the vaccine when you hear the president pushing for it and the cautions, you know, the cautious warnings from his own advisers . So the president s pushing isnt helping. To be a success, a vaccine needs to be proven safe and effective. It also needs to be trusted. Its possible as dr. Fauci said that with the pfizer Moderna Vaccine the Clinical Trial recruitment has gone fast enough that it is
