Trump throws a temper tantrum at Mar-a-Lago, boasting he draws bigger crowds than Dr. Martin Luther King, Jr. did for the "I Have a Dream" speech. Is he freaking out because Harris is surging in the polls? Meanwhile, Harris and Waltz hit Detroit, where they score a UAW union endorsement and tout her economic record. Brian Tyler Cohen discusses his new book, "Shameless: Republicans' Deliberate Dysfunction and the Battle to Preserve Democracy," and then joins Jon and Favs for a game called Take Appreciators.

Jon and guest host David Axelrod discuss Donald Trump's struggles to define Kamala Harris, his rambling interview with Elon Musk, and why the Trump campaign keeps letting their candidate run his mouth so much. Then, they look at Trump and Harris's competing economic messages, how Tim Walz is faring out on the trail, and what the Harris team needs to accomplish at next week's Democratic National Convention.
