The last debate made President Bidens to be the number 1 issue in the campaign which led him to dropping out. Going into this debate, some voters are concerned about Donald Trumps age and his mental fitness. His Campaign Events have been full of sometimes incoherent rambling and if he wont go, Donald Trump would be the oldest person to ever serve as president of. On the other hand, harris will try to present her candidacy is turning the page without abandoning President Biden when the two of them have accomplished during his administration. The New York Times columnist Tom Friedman writes that these of the 23 words that vp harris needs to say Tomorrow Night. Joe and i got a lot of things right. We got some things wrong too. Here is what i have learned. With that, lets get smarter with the help of our Leadoff Panel tonight. Nbc News Washington Correspondent is here to cover the debate Tomorrow Night. Susanne glassman joins us. Hugo lowell political correspondent for the guardian. The biden Trump Matchup showed just time i should to be can affect the campaign. Tell us what is at stake. I am so excited i am tonguetied. You are excited. I have a little dread going into this. I watched Donald Trump and a lot of president ial debates. Many of them will go down in history as some of the toughest political dialogue ever to watch. Since television started airing these things. Donald trump is a blue cert of misinformation and lies when he speaks in these debates. He has a history of talking very aggressively over his opponents. I dont know if the rules will allow that this time. The stakes are incredibly high. We worry across the threshold of the most impactful debate ever in the sense the first debate caused Joe Biden and directly to have to drop out of the race. I still think this one could be one of the most significant president ial debates of our lifetime aside from that one. There are so many questions about harris. Incredible pressure on her. Donald trump. Look, anything is possible. Yamiche, the reason they havent met in person is Donald Trump did not accept a peaceful transfer of power. Its because Donald Trump when he was president of the united states chose not to work with the senate. Tomorrow night, democrats are going to get what they have been waiting for since she became the nominee. She will have the opportunity to prosecute the case against him on stage, next to him, and Show America who she is. Is that her plan . Her plan is certainly to Show America who she is and ive been talking to a lot who are familiar with their Debate Preparations. Her mission is to lay out what her vision for america is, and by doing it, its telling america who she is. There are a lot of americans who are not totally, understanding her background so she wants to give a biography. Talk about her mother enter Middle Class back round and she wants to lay out her policy and give voters including undecided voters, independence, who will be watching this, she wants to give specific things she will do if a Harris Administration happens. Thats why we will see Policy Roll out. She put a policy on her Web Page Today laying out a number of stances. She wants to needle Donald Trump. She wants to get under his skin and her advisers and her team went Donald Trump to go full Donald Trump and what they mean is they want him to lash out to go personal on her. They want him to say the things that are derogatory and maybe even racist. American people can see him at his fullest. They want to make sure he remains calm and gets pulled into those personal attacks, they want her to be focused on everyday americans and how their lives will be better by her administration while also trying to be to Donald Trump into making a mistake. You go, you reported that Trumps Team is worried about which donald is going to show up on the Debate Stage Tomorrow Night. Here is the thing. Whether its naughty or tired donnal, fired up donald, his supporters stick with him no matter what. By this is Debate Performance even matter . If it is ration disasters, they will rationalize it. There are several things going on. The Trump Campaign has looked at the Biden Debate is the model that trump should follow. In their rise, they see that as that was happy trump. That was good trump. Have little quips and could interject about golf and made him look more personable. On the flipside, if you get angry trump, thats the real concern Remakes Ad Hominem remarks. Thats when he starts making remarks about Kamala Harriss Race and gender and those are the areas they dont want to get into because it puts up even his own supporters. Anecdotally, if you travel to Palm Beach and even the Uber Driver tends to be trump supporters. They say this man talks too much and when he gets riled up and frustrated he shoots himself in the foot and its painful to watch. If its painful to watch for trump supporters it will be excruciating for undecided voters, independence, people who maybe they dont like Kamala Harriss policies but they put off by trump and thats the sliver of the electorate that the Trump Campaign needs is part of the coalition to win this. Thats the major concern. If he can turn off even trump supporters, think of what it can do to independence. Susan, at this point, we already know everything there is to know about Donald Trump. Does that make it that much more of an opportunity or a risk for Kamala Harris, who a lot of people dont know yet. Thats right. I think for harris, its about crossing the threshold to being they acceptable alternative to drum. Theres a strong sense that there is a durable antitrump, nontrump majority in the country. He lost the Popular Vote twice. Theres no indication in surveys that he has gained enormously new followers and the subsequent four years. Many people say its remarkable Given Everything that is many people say its remarkable Given Everything that is happened the trump held onto his support but he is not built it up into a considerable majority of the country. He is the only president in American History never to have supportive 50 of the country for at least one day of his presidency. There is the ceiling for Donald Trump. For harris, the trip is to make the election a referendum on trump and reminding people why they didnt want him in the first place while also crossing the barrier for people to be acceptable enough as the alternative. That is where its a difficult job in the Debate Tomorrow because if she just prosecutes the case against Donald Trump, perhaps she one of done enough to introduce herself to independent voters or even biden 2020 voters who are inclined to vote for her but might not feel comfortable enough that they know enough about her. Both of them are very skilled debaters. Yamiche, want to go back to Trumps Team hope they get the trump that showed up for the Biden Debate. Here is the thing. Even if that Donald Trump shows up, he didnt do anything exceptional that night. It was Joe Biden who single handedly lost. If he faces off against Kamala Harris as the trump he was two months ago on the Debate Stage, that might not mean a win for him. Certainly. I was talking to a Harris Aide who said while President Biden mightve had one of the worst residential Debate Performances in history, someone who came a close second was Donald Trump on that stage. They believe that Donald Trump showed himself to be someone lying profusely. Someone struggling, mumbling but didnt have a handle on information. Thats the Donald Trump that harris is hoping shows up Tomorrow Night she wants to make sure that people see that which is part of the reason why there was this backandforth. The Harris Campaign, they want people to see Donald Trump saying the mumbling and saying the things including even cursing at her and using derogatory language. They dont Think Trump had a good debate in june when he debated President Biden. They are hoping if he has that same Donald Trump, that they will be able to use his flaws against him. As you said, she does still want to make sure people walk away from the debate not just thinking, she beat up Donald Trump and she did attack him and landed a bunch of punches, she needs to come away feeling there are people who say, i have a clear vision of what a Harris Administration would look like. A clear vision of why shes not Donald Trump and a clear vision of watching a third term of biden. Ive been talking to Harris Campaign aides and other people who are familiar with Debate Preparation who have been telling me there is this real debate going on about how she differential rates herself. Shes loyal to President Biden. She supports him and supports a lot of his policies. She is the sitting Vice President , but she does differentiate herself and she has different views including on the Capitol Gains and Tax Policy she wrote out last week. It will be interesting to see what all she does to differentiate herself. We will see former President Trump do something like try to lay blame for the withdrawal and the cassa happened after afghanistan. A number of other policies the biden administration pulled out im interested to see how she says i am serving as, at the pleasure of the president but i have my own views and here they are. Lets talk about the double standard Pp Harris is facing. I want to share a bit of trump this past weekend talking about immigrants. Please watch. By the way, colorado was one state, its worse than other states. In colorado, they have taken over. And colorado, they are so brazen they have taken over sections of the state. Getting them out will be a bloody story. Never shouldve been allowed to come in the country. Nobody checked them. Okay. Trump is likely talking about reports that a group of migrants took over an Apartment Building in a rural carla rado. Those reports have been spread online by Elon Musk. The person who owns twitter, one of the biggest reaches in the media landscape. For fact say, lets tell the truth. Police, Law Enforcement and aurora, as well as people who are living in those apartments say this is absolutely not true. Its categorically false. When you go back to Donald Trump, hes promising Mass Deportation and if he wins, he is saying it will be a bloody story. I want you to imagine for a second the reaction in Vice President harris saying anything like that. Anything. Pushing these massive lies. Susan, to the moderators Tomorrow Night have to ask Donald Trump about this comment . In the last 48 hours, he is spreading a massive lie about migrants in this country. Do they have to bring this up Tomorrow Night . I mean, short answer, yes. Slightly longer answer is there are so many, so many things that trump has said even the last week of this campaign that are untrue, inflammatory, reckless, dangerous. Pick your words. Theres this imbalance between harris and what you may call the realitybased Community Versus Donald Trumps campaign which is built upon an edifice of fear mongering. Immigration, you showed the images from the republican national convention. Delegates holding up signs saying Mass Deportation now. One of the things it was striking about attending the convention was this is one of the biggest Applause Lines of the convention. Trump believes, his Hate Speech directed toward immigrants as a class, a category, are the reasons he became president in the first place in 2016. What ive seen in this campaign is the escalation of that rhetoric again and again and again. Its not a surprise that he is making wild, false claims and advancing misinformation. This week its colorado and next week it will be something else. Donald trump has been running the same place since he became a political candidate. Theres an invasion of migrants coming to take over your country. Yes, but of course that same play only worked in 2016. He tried to do it in the midterms. Caravans, caravans. Republicans lost disastrously in those midterms and after those elections, you never heard about those specific caravans ever again. We have to keep our eyes peeled because the stories, many of whom are not true, are getting spread by rightwing media, by Elon Musk, by his backup dancers. And by Donald Trump. Thank you all so much. Donald trump takes the Big Lie to a whole another level. His plan to jail lawyers, donors, and Election Officials if he wins office.

Lets discuss this in more with former democratic senator of Doug Johnson Stuart stevens, Mitt Romney and george w. Bush campaign. His with the Lincoln Project. Are people taking this threat seriously enough . No. They are not. There is this reluctance to accept what trump is saying. Look, i think the majority of the blame lies with my old party. These republican senators and governors and elected officials who are supporting trump, they no theres not election fraud. If there was election fraud, what are they doing being elected . How does it work . They know this and yet they are remaining silent about it. This is a system that is based upon goodwill and faith. A lot of our elections are conducted by volunteers.
