GOP 3, Democrats 0.

The Republicans are (surprise!) beating Democrats in the number of presidential candidates who are creationists.

But nah, there's no religious influence whatsoever on the Republican party.

UPDATE

Sullivan points to this post by a Catholic blogger, pointing out that Brownback, who converted, has no business questioning evolution. And there's this tidbit:

Lest there is any doubt about this hypothesis, simply note that the denial of evolution is concentrated in a small group of American evangelicals. You do not see Christians around the world disdaining science in such a manner. And it goes beyond evolution. Just look at the global warming debate. In a recent poll, despite the overwhelming consensus of the evidence, only 13 percent of Republicans in Congress believe human activity is leading to global warming.

Your GOP, 2007.
