‘The Doppelganger Is at the Wheel’

Naomi Klein’s book “Doppelganger” is a journey into the world of MAGA and right-wing conspiracies. But it’s also a look at how the left’s political culture sits in relation to this mirror world. On “The Ezra Klein Show,” the writer talks to the Times Opinion columnist Ezra Klein about how the use of the “mute button” on social media has spilled offline as well, creating political communities that are isolated from one another.
