COLUMBIA, South Carolina — Bernie Sanders won the first three states over the primary cycle. But, this weekend, he’s arrived in unfriendly territory: a state where most Democrats go to church every Sunday and most Wednesdays, to boot.

The socialist from Vermont, who promises a revolution right here on Earth, is the candidate of atheists, agnostics, and the unaffiliated. That’s a young, white demographic. South Carolina, where about half of the Democratic electorate is African American, is a state of black Baptists and Southern Baptists.
