In this episode, Brookings Vice President Darrell West and Senior Fellow Camille Busette discuss themes from West's new book, "Divided Politics, Divided Nation: Hyperconflict in the Trump era," including the economic, geographic, racial, and technological factors that have exacerbated U.S. political polarization to its current breaking point, and what's needed to build a healthier democracy. West and Busette also speculated how these pressures may affect the 2020 presidential race.
