Kamala Harris pulls ahead in three key swing states as Donald Trump continues to flail and fume to donors and supporters. JD Vance tries to go on the attack in a trio of network interviews on Sunday, but things don't go quite as planned. Then, as Harris starts laying out her own policy agenda, the officially defunct Project 2025 ends up back in the news, this time with a series of leaked training videos offering a bleak, and bizarre, picture of a second Trump term.

More and more Republicans are asking Donald Trump if it might be possible for him to stop the personal attacks on Kamala Harris and focus on a persuasive message. His answer? Absolutely not. In yet another country club press conference, Trump says he's "entitled to personal attacks" because he doesn't respect Harris, calls her stupid, and rants about communists. Meanwhile, Harris and Joe Biden hold their first joint event since Biden stepped down from the race, and it's full of good policy and good vibes. Plus, Tim Walz talks tacos, and RFK Jr. might be looking for an exit strategy.
