What's Happening to "Value Voters?"

One leader of the Southern Baptist Convention says that to back Donald Trump, Christian “voters must repudiate everything they believe,” but polls show millions of evangelicals are not demanding that Trump adhere to precepts of the once-dominating Moral Majority. They're supporting a profanity-spouting gambling-house owner who's been married three times with an inconsistent history on abortion and same-sex marriage. Cruz, Rubio and Kasich are passing the litmus tests, so why is Trump leading with voters who call themselves devout Christians?
