If John McCain can't control Palin now, what's going to happen if he becomes president?

With all the news of the past few days, that the McCain campaign is at wit's end with Sarah Palin, that she's a "rogue elephant" who won't listen to McCain or his advisers, that she does what she wants and to hell with McCain and the campaign, what does this bode for a McCain presidency? It means that we'd have another Dick Cheney on our hands, but one that's a heck of a lot dumber. And that's dangerous. It's been bad enough having an evil genius pulling Pinocchio's strings the past eight years, but can American really afford an evil idiot in his place?
