'Really fun': Ex-senator tells 'Morning Joe' she loves seeing Trump face his 'kryptonite'

MSNBC's Claire McCaskill has enjoyed watching Donald Trump fall behind Kamala Harris in the presidential race — and she's not sure he can recover.

The Democratic Party's hopeful has erased Trump's lead in several swing states since joining the race, and the former Missouri Senator McCaskill told "Morning Joe" that Trump was struggling to turn things around.

"It's been really fun, I think, for people who were very worried about Donald Trump getting in the Oval Office again," McCaskill said. "You know, what's really interesting about this is that when Trump is marginalized and cornered, his instincts are not to track to the middle or to become more reasonable in what he says. He really gets more and more bizarre."

The Republican nominee has already been laying the groundwork to claim the election was stolen from him, as he did in 2020, she said.

"The more he feels pressured that he is losing, that's where the old 'they're going to cheat' thing came from, when he started worrying in April of 2020 that he couldn't win," McCaskill said. "So, really, what would change this trajectory of these polls would be something changing in the candidates."

Harris and her running mate Tim Walz have been packing large venues in swing states, and Trump has been reduced to ranting on Truth Social and claiming she'd used artificial intelligence to generate a photograph of a crowd of thousands greeting her plane at a Michigan airport.

"Now the debate is a moment that could upset this momentum," McCaskill said, "but I'm trying to figure out what would really disrupt this momentum going forward for Kamala Harris, because I believe Trump will get worse and not better, when he is confronted with reality of these polls day after day, to say nothing of the size of the crowd, which is we all know, the Harris crowds are his kryptonite."
