Nancy MacLean, author of "Democracy in Chains: The Deep History of the Radical Right's Stealth Plan for America" in conversation with Richard Wolinsky.

Duke University Professor Nancy MacLean, in researching the life of libertarian professor James Buchanan, discovered the philosophical underpinnings of what Hillary Clinton (almost unknowingly) called the "vast right-wing conspiracy." Funded by Charles Koch and other donors, they've taken over the GOP and have an agenda, she says, that ultimately will allow minority rule in the United States for the forseeable future.

In this interview recorded October 20, 2017, she discusses the role of Buchanan and the Mont Pelerin Society in the underpinnings of this gradual take-over of the state and federal government, and what the goals are, according to her research. "Democracy in Chains" was on the short list for the 2017 National Book Award.
