In this episode, host Jack Delehanty speaks with Stanford sociologist Doug McAdam, whose 2014 co-authored book Deeply Divided: Racial Politics and Social Movements in Postwar America traces the roots of polarization in today’s politics back to the national struggle over civil rights in the 1960s. In their conversation, Jack and Doug focus particularly on tensions between modern social movements and the interests of party leaders developing in this year’s presidential election. They consider how the ongoing national conversation about racial inequality might be changing how Americans relate to major political parties.
