Kevin Drum lists the reasons why Perry won't be president. Among them:
He's too dumb. Go ahead, call me an elitist. I'm keenly aware that Americans don't vote for presidents based on their SAT scores, but everything I've read about Perry suggests that he's a genuinely dim kind of guy. Not just incurious or too sure about his gut feelings, like George Bush, but simply not bright enough to handle the demands of the Oval Office. Americans might not care if their presidents are geniuses, but there's a limit to how doltish they can be too.
