Sarah talks to Lydia Bean, author of The Politics of Evangelical Identity, a study of how white evangelical political identity is shaped by grassroots “folk theory” about what it means to be a good Christian. Lydia explains why evangelicals might react differently to people coming from outside their religious “tent.” She talks about why evangelicals see their messaging on issues like abortion and same-sex marriage as compassionate, even when outsiders may not. They discuss the economic differences between American and Canadian evangelicals on issues like socialized medicine. Plus: Why “faith-based” campaigning by Democrats falls flat, and how a new set of rhetorical tools can change that.
