Think Out Loud

History, demographic shifts, social science, and the evolving media landscape are all part of the puzzle political journalist Ezra Klein puts together in his new book "Why We're Polarized." We talk with Klein about how polarization is changing our country. Ezra Klein will be at Powell’s Books at Cedar Hills Crossing Wednesday, February 12 at 7pm. He’ll be in conversation with Omar El Akkad, author of 'American War.'
