Nancy MacLean is a professor of history at Duke University and an award-winning scholar of the twentieth-century U.S., whose new book, “Democracy in Chains: The Deep History of the Radical Right’s Stealth Plan for America,” has been described by Publishers Weekly as “a thoroughly researched and gripping narrative and a feat of American intellectual and political history.”
