Rick Perlstein: From Reagan to Trump; Katie Porter on the postal service, Ella Taylor: '60s TV

Rick Perlstein talks about the rise of Reagan, from what seemed like a career-ending defeat in the 1976 GOP primary, to his narrow victory in the popular vote in 1980--and how the darkness of the culture war has shaped the Republican Party that Trump came to dominate. Rick's long-awaited book, 1100 pages long, is "Reaganland: America's Right Turn, 1976-1980." Also: Katie Porter, the new member of Congress who flipped a longtime Republican district in Orange County, talks about defending the postal service and about ending student loan debt. Plus: we’ll talk about politics on TV in 1968 with Ella Taylor -- and about a new documentary, called “The Sit-In: Harry Belafonte Hosts the Tonight Show,” when his guests included Bobby Kennedy, Martin Luther King, and also Aretha Franklin. And it’s streaming now on Peacock.
