This week, Karin talks to Ali Goldsworthy, founder of the Depolarization Project, about why our politics has become so polarized and what we can do about it. Why can't we seem to talk to people from "the other side" anymore? Should we worry that the Democratic Party itself will be divided and polarized after a hard fought primary? Why is that that the data suggests liberals are actually the least likely to befriend people on the the other side? Why is it actually smart politics to exacerbate polarization? Also this week: A news roundup covering the Republican candidates running against Trump in the GOP primary, the exit of Starbucks CEO Howard Schultz from the race, and more.
