This week, live from Chicago to celebrate 20 years of the Political Gabfest, Emily Bazelon, John Dickerson, and David Plotz discuss the Trump vs. Chicago showdown and the dynamics between progressive and centrist Democrats with former Chicago Mayor and Obama White House Chief of Staff Rahm Emanuel, what threat President Trump poses to the future of American elections and how to push back, and memorable moments from Gabfest history. For this week’s Slate Plus bonus episode, live from Chicago to celebrate 20 years of the Political Gabfest, Emily, John, and David take audience questions and discuss whether the damages caused by the Trump administration can ever be reversed, the most controversial topics from the show’s history, and more.   In the latest Gabfest Reads, Emily talks with Yale law professor John Witt about his new book, The Radical Fund: How a Band of Visionaries and a Million Dollars Upended America. They explore the remarkable story of the Garland Fund—a small 1920s foundation that bankrolled early work by A. Philip Randolph, and others who would go on to shape the civil rights and labor movements.   Email your chatters, questions, and comments to gabfest@slate.com.
