Along with Matt Grossmann, the co-author of my new book Polarized by Degrees: How the Diploma Divide and the Culture War Transformed American Politics, I've recently appeared on two major podcasts devoted to American politics. You can hear our discussion with MSNBC's Chris Hayes on his podcast Why Is This Happening? here, and our talk with Galen Druke of the FiveThirtyEight Politics podcast here. Both episodes are also widely available on popular podcast apps.
