Well, a lot here will disagree with you on that one, Doppelganger, but in the event she's lucky McCain lost, because if he'd won she would have been permanently associated with John-boy's stupidest ideas, like some variation of cap-and-trade, as well as a Democrat-dominated Congress slipping the shiv to both of them at every opportunity with the press all too eager to pile on any misstep and paint the roadblocks in Congress as his fault.
You can buy into the 'She's sure no genius' propaganda if you wish, but some of the most dangerous and/or nutty Presidents we've ever had were supposed to be big super-smart guys, like Woodrow Wilson and of course Jimmuh and OhBummer. The best have been men who, while intelligent, more importantly had the character to stand for their principles, a vision of what policies would be needed to address them, and had the fundamental common sense and humility to see eyeball to eyeball with opponents and allies instead of looking down on them form a perch of superiority. A great academic record really seems to be a completely crappy predictor of Presidential performance.
