Who cares what Ron Paul thinks about evolution? He doesn't believe it's the government's job to cram creationism down kids throats, so what he personally believes is fairly irrelevant. And anybody who knows anything about Ron Paul knows that he isn't some ignorant, fundamentalist bible-thumping hick like Mike Huckabee... Ron is a freaking medical doctor who got his degree from Duke. He's clearly an intelligent man, who just happens to have this one quirky religious thing going on. And lots of very intelligent people are conflicted over the whole evolution / creationism thing, because of their religious beliefs.
Who cares? Nearly all US politicians are complete idiots (often insane people). What matters is where a given politician stands on issues I care about. What are you afraid he's going to do, outlaw evolution?
