After what feels like endless speculation - although it's only been about two weeks - Kamala Harris has chosen her chosen Minnesota Governor Tim Walz running mate. Walz has a track record of winning even in conservative-leaning districts. The Trump camp has already begun its campaign against Walz, labelling him a dangerous radical. Joining the program is Geoff Duncan, a Republican who served as the Lieutenant Governor of Georgia until last year and who now he says he'll vote for Harris over Trump.  Also on today's show: "Pod Save the UK" cohosts Nish Kumar and Coco Khan; Betsey Stevenson, Professor of Public Policy and Economics, University of Michigan; author Edward Wong ("At The Edge of Empire")  Learn more about your ad choices.
