On The Posner Show, Sarah talks with Geoff, author of the book Rule and Ruin. Geoff argues that we are living in a new era of a far-right Republican Party. They discuss the role of the John Birch Society in the GOP’s rightward tilt in the 1960s, and its legacy of attacking conservatives for betraying its view of American ideals. Geoff breaks down what last year’s Republican National Committee “autopsy” says about the death of moderation in the GOP. Can Mike Lee or Chris Christie be the moderates of the future? Plus: Why the conservative movement has no pope anymore.
