Jimmy Carter was as inept fool of a President. I'm not saying he wasn't a smart man in other ways, just on domestic, foreign policy, diplomacy, government, human nature, economics, and common sense, he was the dumbest President we had in my lifetime. But other than that, he was a revisionist, the screwed up everything he stuck his nose in. The only thing he's done well is shut up and occasionally help Habitat for Humanity.
