This week Josh Zepps chats about the 2016 Republican presidential primaries with journalist Sarah Posner, a senior correspondent for Religion Dispatches and the author of Gods Profits: Faith, Fraud, and the Republican Crusade for Values Voters. She is an expert in the political machinations of the religious right in the United States.

The current GOP field has Seventh-day Adventist Ben Carson and the newly Bible-loving Donald Trump battling for the top spot in polls, despite their theological differences with the Evangelical base of the party. Posner explores what’s behind the appeal of these two unlikely front-runners, compares their very different demeanors, and weighs on such topics as the influence of Pope Francis and the prospects for atheist political candidates.
