Right-wing heartland Republicans may believe in it, but it's the left that truly loves creationism. Political outrage is fine, but everyone has to acknowledge at least to some small extent that sentient humans can differ on how often we should drop bombs on Afghanistan or when and whether women should have access to abortion. But creationism? That's an argument about facts, not morals. It's the ultimate proof that all those Red State yahoos are not just cruel, heartless bastards, but are congenitally, intentionally and hopelessly stupid. If the right lives to accuse their enemies of immorality, the left lives to accuse theirs of idiocy—and nothing screams "idiot" like looking at a Tyrannosaurus and trying to figure out how it could’ve fit on the ark.
