While polls showed voters remained somewhat skeptical of a Mormon presidential candidate, few would outright criticize Mitt Romney and Jon Huntsman for their religious affiliation during the 2012 presidential contest.
One major exception took place during a conservative gathering in Washington in October 2011.
Robert Jeffress, senior pastor at the First Baptist Church in Dallas, introduced Texas Gov. Rick Perry, calling him a "proven leader, a true conservative and a committed follower of Christ." After the speech, Jeffress let loose.
"Rick Perry's a Christian. He's an evangelical Christian, a follower of Jesus Christ," the pastor told reporters. "Mitt Romney's a good moral person, but he's not a Christian. Mormonism is not Christianity. It has always been considered a cult by the mainstream of Christianity."
