Karl Rove is not a believer, and he doesn't shout it from the rooftops, but when asked, he answers quite honestly. I think the way he puts it is, "I'm not fortunate enough to be a person of faith."
The quote itself is far more interesting than the fact, which doesn't surprise me in the least. If you don't believe in God, then why would you think believers are "fortunate" for putting their faith in a nonexistent higher being? You wouldn't. Yet Rove, for political reasons, must genuflect to the notion that religious people are morally superior to atheists. The line perfectly encapsulates the condescending and way Republican elites have manipulated religion.
