Vox.com co-founder Ezra Klein talks with Recode's Kara Swisher about his new book, Why We're Polarized, the rise of systemic "zero sum" party politics, and how Klein himself has been polarizing in the Trump era. Klein and Swisher also discuss the racial, religious, and urban/rural splits between Democrats and Republicans, the (good and bad) impact of social media on the public discourse, and the one thing regular people can do to combat polarization in their own lives. Plus: Why "Congress should stop being such a bunch of wimps."
