Andrew Walworth, Carl Cannon, and RCP White House correspondent Phil Wegmann discuss Donald Trump’s press conference yesterday (including his story about a helicopter ride with former San Francisco mayor Willie Brown) and Kamala Harris’ campaign strategy in Arizona. Then, they talk about whether Democratic vice-presidential candidate Tim Walz will appeal to red-state voters in the upper Midwest and the 50th anniversary of Richard Nixon’s presidential resignation. Next, Andrew Walworth talks to foreign policy expert Peter Berkowitz of the Hoover Institution about the possibility of a wider war in the Middle East and whether Iran will attack Israel as soon as this weekend. And winding it up, Carl Cannon talks to historian Lindsay Chervinsky, executive director of the George Washington Library, on the role of vice presidents in governing, and what history tells us about the Harris candidacy.
