If she decides not to run, it would be understandable, because she herself is dirtier than her husband ever was, and the GOP has many gigabytes of evidence to prove it and would delight in breaking it out. But even if she does run, she's already screwed her candidacy bigtime, overreacting to a blip on her radar named Barack Obama:
MATT LAUER: But do you think he's qualified? I mean, he's a fellow Democrat. Would you be comfortable with him in the White House?
FUTURE PRESIDENT CLINTON: I'm going to let all of those decisions be sorted out by voters.
Huh? Obama is even more certain to be the 2008 Democrat vice-presidential nominee than Hillary's a slam dunk for the top spot. And she disses him like that? He's the greatest guy in the history of the world, and will follow two Clinton terms and be our next-next president in 2016. (Like Al Gore, sort of.) He's an asset, not a rival.
If for some reason, Sen. (pro tem) Obama doesn't get the VP nod from his party, its near-monolithic black vote may well just stay home. A black person on the ticket, as Everett Dirksen might have said, is an idea whose time has come, and Barack Obama's time has come, albeit a bit too suddenly. (That's not his fault---most presidential timber has already been felled and even provided the axe, like Newt Gingrich, for instance.)
She's not even nominated yet, and she's already made the first big mistake of her presidency. Foreign policy is hard enough, but first you have to master your own party, and certainly not eat your own. (But more on John McCain later...)
