In the second episode of our new podcast series, "Horns of a Dilemma," William Inboden interviews Mark Updegrove, president and chief Executive of the LBJ Foundation, and author of the new book The Last Republicans: Inside the Extraordinary Relationship Between George H.W. Bush and George W. Bush (Harper 2017). This new book draws on interviews with both Bush presidents to explore their formative experiences as well as their perspectives on public service, America's role in the world, Donald Trump, and the transmutation of the Republican Party that has transfixed the United States and turned its politics upside-down.
