CNN's Abby Phillip: Joe Biden's Support Is Eroding From 2020 Level, Trump's Is Not

SCOTT JENNINGS, CNN: it is quite a dramatic thing to know that Trump never led by, now he leads him in almost all the polling and the swing state polling that's come out, it's really quite a remarkable thing.

ABBY PHILLIP, CNN: I mean, what is the answer? How could he be losing to this guy?

S.E. CUPP, CNN: Well, so Biden has a problem that Trump doesn't have, and the same is true of the reverse, stay with me.

Trump's base is way more loyal and rabid and condensed. And this was a project that Trump and Republicans encouraged, purifying the party, getting rid of apostates, getting rid of good conservatives, like Kinzinger and Romney and Cheney. They want all those people out. And here was Trump bragging about really reducing the base to pure MAGA. They've done it. And so they're all with him no matter what.

Joe Biden doesn't have that kind of loyalty. You've seen a lot of Democrats wondering if they're going to stay home or not.

Trump has a problem that Joe Biden does not. If Joe Biden were losing 40 percent of the vote in every state to Dean Phillips, they would be freaking out. Trump is doing that. He is losing 40 percent of his own party to Nikki Haley. I'm not saying she's going to win. I'm saying what that says about his weakness in a general election.

PHILLIP: I want to about this, though, S.E. I want to talk about this because the polling, the same polling that has Joe Biden losing to Donald Trump, here's what it says about Donald Trump's voters, 97 percent of the people who voted for him in 2020 say they would vote for him again this year.

But hold on, there's more. 83 percent who voted for Joe Biden in 2020 say they would vote for him again. The person who is eroding support is actually Joe Biden, according to this.

JENNINGS: I think a lot of the Republicans who were voting against Trump in these primaries didn't vote for him in 2020. I think they are Republicans who hated Trump before. They voted for Joe Biden, and now they're planning to vote against Trump again.

I think the last point you made is the most important. Trump's base is there. It's pretty solid. And not only that, if you look inside of The New York Times/Siena poll that Harry was just talking about, there's obviously new people coming in. Trump was leading among Hispanics. Trump was tied among women. He had a quarter of African-American voters. These are absolutely -- if those splits hold, there's no way for Joe Biden to win, because that's a whole bunch of new people coming into the Republican Party.

So, you could shed some of the folks you were talking about. If you're replacing them with this multi-generational, multi-racial working class coalition of people that never vote Republican, that would be a new base for Trump that's not shown up in these primaries necessarily, but could show up in November.

PHILLIP: So, now that is the theory if the polls hold as they are now, but there is virtually a lifetime between now and November.

President Biden sat down with The New Yorker's, Evan Osnos, he had an Oval Office interview. Biden was incredibly confident. He basically says, I beat this guy once, I will beat him again. And the theory of the case that the White House and the campaign have is that when voters are not answering pollsters' questions and they are going into the ballot box, they say something different from what they might say to the pollsters. Do you buy it?

CUPP: Listen, I think it's real Trumpian. A lot of my Democratic and liberal friends spent the weekend slamming the polls and the media for covering them, and that feels very Trumpian to me.

The polls are telling us, I think, a pretty accurate snapshot of the disappointment and disillusionment with Joe Biden. Does that mean Democrats are going to stay home, or when it really comes down to it, are they going to go out and vote for him because Trump is on the other side? That's the question.

But you can't deny, if you're at the White House, Democrats, Democratic voters, you cannot deny that he is a weak candidate, that Joe Biden has serious problems. They're not just his age. They are issues like immigration, crime, the economy, that voters do not feel he has policy-wise solved, or is even getting that they need to be solved.

So, I think there's systemic problems inside the Biden campaign, some of which he could overcome, some of which he really can't.
