On The Posner Show, Sarah speaks with Sarah Pulliam Bailey about Mitt Romney's commencement speech at Liberty University and how evangelicals are dealing with Romney's Mormonism. How much will President Obama's endorsement of same-sex marriage impact white evangelical turnout, or black or Latino enthusiasm? They also dissect the theology of Obama's new support for same-sex marriage, the reactions of his spiritual advisors, and whether his new position will hurt him with "new" evangelicals who say they care about more issues than just the culture wars. Are "anti-gay rights" and "anti-gay" the same thing? Plus: The generational divide over same-sex marriage—will megachurches start to lose members?
