The question is not whether a legislator in Tennessee identifies as a Christian. It's what kind of Christian they are.
Nearly one-third of lawmakers identify their religious affiliation as Baptist, and the rest say they're from another Protestant denomination or they're Catholic. Only one mentions another faith: Nashville Rep. John Ray Clemmons, who says in his official bio that his family is a mix of Christian and Jewish.
That's not completely out of line with Tennesseans as a whole. Four of five of the state's adults say they're Christians.
