In this article on the race for the presidential nomination, religion figures prominently. Two contenders are controversial because they're mormon.
"Evangelicals who dominate the Iowa and South Carolina nominating contests are unlikely to back Romney or former Utah Gov. Jon Huntsman; some call the two men's shared Mormon faith a disqualifier."
Then there's Rick Perry, and, although the article doesn't mention his religiosity, it's what I think he's most famous for, thanks to his Texas Bored of Education and prayers for rain. (How did that work out, anyway? I think the drought's still going strong, isn't it?)
