And tensions between them. Also tonight, the president is preparing to address the nation and the many challenges hes facing right now, ill ask a key member of the biden camp what the president needs to accomplish in his state of the Union Address tomorrow night and a terrifying close call for the Ukrainian President , Volodymyr Zelenskyy, or russian missiles striking not far from his convoy and killing five people welcome to our viewers here in the United States and around the world. Im wolf blitzer, a urine. The Situation Room tonight the path is clear for President Joe Biden and former President Donald Trump to do battle again an unprecedented and likely very divisive rematch that both of them have been expecting. And Many Americans have made it clear they dont want youre cnns jeff zeleny tonight. The curtain finally goes up on a historic president ial rematch. Joe biden and donald trump emerging from Super Tuesday primaries as the effective nominees of their parties. But there are warning signs in winning with both men facing distinct challenges of rebuilding their coalitions. Nikki haley, The Last Standing republican rival suspended her campaign without offering an endorsement. It is now up to donald trump to earn the votes of those in our party and beyond it, who did not support him and i hope he does that after months of warning republicans about trumps vulnerabilities, xi bluntly said the burden is on the former president to win over her supporters and unify the party at its best. Politics is about bringing people into your cause not turning them away. And our conservative cause badly needs more people this is now his time for choosing any fencemending got off to a rocky start with trump saying on social media, nikki haley got trounced last night in record, sen. Fashion, President Biden struck a deal different note and extended his hand saying donald trump made it clear he doesnt want nikki haleys supporters. I want to be clear. There is a place for them in my campaign. Its far from certain. Were haley voters ultimately will go. But an analysis of cnn exit polls from five states found only 19 said they would be satisfied with trump is the nominee. And 79 dissatisfied in the closing days of the primary, voters expressed the challenges of unity. Trump cant win without her supporters in called her names, isnt going to help him when she worried that some of her supporters may go to biden maybe third party eight months before the General Election, the Republican Party is rallying around trump november 5 is going to go down as the single most important day in the history of our country. Senator mitch mcconnell, who hasnt spoken to trump in more than three years, offered his endorsement saying it should come as no surprise that as the nominee, he will have my support tonight after a string of democratic primary victories, President Biden is preparing to make his case at the state of the Union Address on thursday, a Primetime Opportunity to tackle myriad challenges he faces to win reelection. Biden easily swept away longshot rivals like dean phillips, but a series of protests, votes made clear he faces task of Uniting Democrats to like in minnesota on tuesday, where uncommitted received 19 of the vote with a General Election contest. Finally, taking shape, history will be tested a new, as trump seeks to become the first president since Grover Cleveland and was voted out of office to be sent back for a second term now, the sql between biden and trump is cemented, but it will play out in a vastly different political climate. The race is filled with so many wildcards. Trumps criminal cases, bidens Foreign Policy challenges, and of course, the fitness for office of both candidates but there is no modernday historical guide for the eight Month Campaign to come. The stark contrast of which will come into sharper view in the state of the Union Address and response tomorrow night, wolf lots of tension going on right now. Jeff zeleny, thank you very, very much. Lets get some more on all of this on the fight to win over nikki haleys supporters, in particular, cnn an accurate Kaitlan Collins is joining us right now. Kaitlan after telling haley donors they were banned from joining maga. Now, the former president seems to be reaching out to them for support, but not with any Olive Branches or anything. If you looked at his post earlier today right after nikki haley nails that she was exiting this race, he talked about how he blamed most of her supporters. It was the term that he is were farleft radical democrats. It wasnt exactly what someone maybe whos politically savvy and looking at the numbers would necessarily saying compare that as the Haley Campaign is to what joe biden said in his statement where he was making this appeal to them saying yes, we disagree on the issues themselves. Sometimes we agree on the principle of democracy south, it was a very different tone from the two of them. And i can tell you thats what the candidate is doing, but the campaign itself and what theyre looking at on the trump side, wolf, here are the numbers and yes, nikki haley only won two of these nominating contests, but out of that, she got over half 1 million votes, close to 600,000. And some of these Battleground States look at North Carolina alone. She got 250,000 votes there. Trump lost the margin in 2020, North Carolina was only about 75,000 votes. So Trumps Campaign is certainly looking at these numbers that doesnt mean all of the haley voters, obviously are going to go to President Biden side and vote for him come november. But the campaign itself is looking at those numbers. And i think what you can tell that by the evidence of that trumps speech last night, he did not attack nikki haley the way he has been so horribly online, and he instead focused on the issues that could appeal to her voters. Yeah, very significant development. Kaitlan stay with us house, want to bring in more of our Political Team and our political director David Chalian is with us, walkers youve been looking very closely at those Exit Poll Results that we got last night. Walk us through a potential warning sign for trump right now, based on what you saw . Yeah. I just want to pick up on something kaitlan is saying here though the Trump Campaign by clearly being aware they want to appeal to some of those haley voters. Shows that they are on a dual strategy. They yes, they want to expand the electorate and the maga base, but they also understand because its not just haley voters as some mythical thing. What she represents independent voters trump resistant republicans. They need those as part of the polled here as a game of addition, if you look in the Virginia Exit Poll last night, we asked folks, are you going to vote republican in november regardless of the nominee . Now, this is among haleys voters in virginia, 69 say no, its not an automatic vote for the republican in North Carolina, even more so, haley supporters said 79 said no, i am not going to vote republican in november, regardless of who the nominee is now there may be folks that are saying no, that are still going to vote for donald trump. In fact, im sure that there are, but there is a sizable enough bloc that we see in each one of these contests of the haley voters that present a challenge to the Trump Campaign if they are going to rebuild the kind of coalition that proved victorious for them in 27, i think were seeing a lot of that also on the left are were seeing a lot of democrats who arent really enthusiastic about President Biden. And were seeing many voters who are saying, whose policies have personally helped you. They say donald trump and whose policies have personally hurt you. They say joe biden. So i think the democrats are also going to have trouble getting their own democrats out. And so that the key is who has the most enthusiasm, and were seeing many polls showing that donald trump has the enthusiasm to get voters out and joe biden is going to be struggling with that. And on top of that, biden has had the luxury of being the incumbent president and has a tremendous in this war chest. Now, donald trump, with a being the presumptive nominee, he has the tools of the rnc to help with fundraising, joint fundraising agreement Election Integrity units, and the Communication Shop from the rnc. And so now were going to see them shape up and really go fullcourt press against President Biden. So i dont i think the losing strategy, if youre going to try and make the electorate enthusiastic about this rematch, they are saying they are not. And so i dont think thats the strategy to win. You have to talk about facts in this moment and talk about what it means to have a donald trump presidency. And then we had this thing called covid that sent our economy into the tank thanks. And that joe biden came and got it back on the rails, got us out of our house, got us to not go into a recession and he is trying to bring the country back together. He is trying to make sure that the numbers on inflation and jobs are improving. And so the Biden Campaign, this is why we have campaigns, right . We have campaigns. So you can go out and youve talked to the voters its why the administration is doing the policy and then the campaign cells. It but if the campaign wants people to run in the streets, jubilant about this rematch. Theyre telling them theyre not and i dont think thats what youd need to do this election cycle. You need to tell them how youre going to continue to work to them and improve the quality of their life . Yes, thats interesting, kaitlan, because trump has already announced that when the president delivers his state of the Union Address tomorrow night, he Will Counterprogram Social Media and go after President Biden. Specific points during the course of the president s speech. And hes also challenging President Biden now to a series of debates, even though he refused to debate his republican look at opponents during the primaries. Yeah, i dont think its as in prize for trump to say hell be live tweeting something. I mean, i think he pretty much done that every single day of his live even if its not on twitter necessarily, with the debates themselves. Not a surprise if youve been talking to sources in trump world, they have said all along, even when he was against the republic we can primary debate or debates or refuse to go against any of his challengers that the general would likely change that if he was the republican nominee. The one thing is he cannot stand the Nonpartisan Committee that puts on those president ial debates. So thats the big question here. The group that i should note has been doing this since 1976 i think part of whats driving trump what was that . He feels incredibly bullish about how he would perform against President Biden in a debate. But ill remind everyone that back in 2020 when they had a series of three debates, they only did too. We heard the exact same thing from all of our trumps sources that they felt very confident going into that debate. Essentially, none of them. So that afterwards they thought that first debate went terribly for them and they thought they improved by the second one. So i think its covid. Its also because he thought the real you never know when youre gonna get with donald but dont you . I do think though there is risk for both of these guys in a debate, i think a debate between them is going to be the whole country on edge seeing, you know, is joe biden gonna be able to perform in a way that is effective and can communicate or does his age and his fragility at times get the best of him . Does donald trump go off the rails in some way that completely just blockades a whole segment of the electorate that his team would be trying to woo. I just think, well i do anticipate there probably will be a debate. I think it is one that is a high stakes, probably higher stakes than weve ever seen before for both of those cats. Why tomorrow is so important for joe biden, the state of the Union Address, it is. All eyes will be on the current president and wants to know tell me what youve done and tell me what youre going to do and make me feel compelled to support you again, it is the restart of the campaign. It is. We now know after Super Tuesday yesterday, it is most likely that donald trump is going to be the nominee. It is the rematch that most americans dont want to have, but we are having it. And so joe biden has an opportunity to almost reintroduce himself to the country. Well, heres the, heres the challenge hes also facing. He is going to go out there. And if he wants to talk about policies, hes going to have an uphill battle, really convincing American People that the economic numbers are positive for them. You might say the numbers are good. A lot of democrats say they are, but the American People dont feel that and perception is reality you can also hes going to talk about the border, the border crisis has gotten tremendously worse than hes been an office and he is going to have to show what is he going to do in order to secure the border. And were seeing all of these Foreign Policy crises, whether were talking about in gaza and ukraine, israel he is one had to convince the American People that the money were donating or contributing to these areas is being wellspent and its in furtherance of democracy, but even more aside from policy, he needs to demonstrate he has the digger in the vitality, in the energy and enthusiasm to do the job because that is one of the most important things people will be looking. And i think the white house is well aware of that. Weve been talking to them. They understand that. Obviously the State Of The Union is always felt substance. Everyones trying to get their, their goals that weve been talking to lawmakers all day. You were saying, i hope you mentioned this. I hope youve mentioned this. That happens every time for any State Of The Union, for any president. But i think what President Biden the white house knows that the style over the substance is what is going to be really what stands out to voters. What weve heard from People Inside Biden World is that last year they believe he surpassed expectations expectations where he was responding to people like Marjorie Taylor greene and the republicans on protecting Social Security being medicare, were interrupting him. So they feel like the stakes are actually higher because he did they believe so well, last year. And so thats what youve been hearing from his allies, is that he could be an enemy of his own making. And the performance said he had last year. Yeah. And listen, it is a big moment. This is the earnest start of the General Election. Weve got an eight month General Election. These are the two nominees hes not, going to go give a Campaign Rally speech, but the president is going to leave with voters tomorrow. The contrast that he plans to run on for the next eight months. And thatll be a really important piece for him. It is a General Election that the American People are not really eager to participate in, but its the one that theyve got. Lets see how tough he gets going after trump tomorrow night its always very sensitive state of the Union Address is supposed to be the official address before a joint session of congress, an invitation. And its supposed to be about policy and substance, not necessarily politics, but we shall see kaitlan. Thank you very much, everybody. Thank you very, very much.
