Rick Santorum — a pious Roman Catholic — has gotten knocked for losing the Catholic vote to the Mormon Mitt Romney, but those who note this generally take a simplistic view of “the Catholic vote.” They confuse the positions taken by the bishops with the positions embraced by rank and file Catholics, and wonder why Santorum doesn’t get more Catholic votes. Hint: maybe it’s because lots of Catholics disagree with their bishops. See “contraception” and “divorce and remarriage.”

That said, Rick Santorum is poised to win the Kansas caucuses today, and if he does, it will be because of the support of the conservative “purity Catholics” that are more numerous in Kansas than other parts of the US church. And in a caucus state, you can be sure that they’ll turn out.
