Now that Combat! blog’s endorsement of Jon Huntsman has somehow failed to catapult him to front-runner status, we are forced to consider Rick Santorum. The former Senator and Very Good Boy from Pennsylvania is running third in the most recent Iowa poll, suggesting that he might conceivably win tomorrow’s caucuses. There is still no way he will become President. He won’t win the Republican nomination, either. The man who once compared gay marriage to sex with dogs and corpses will never win a national contest, for the historical reason that bigotry only works on the state level. And bigotry is Santorum’s whole damn raison d’etre.
