Atrios has a post on how, whatever happens today, Obama's campaign has clearly put the lie to arguments made against his electability and demonstrated at least the capacity for victory. I completely agree, and electability considerations were never part of my calculus in supporting Clinton for the nomination.
For one thing, my instincts about who is and isn't electable are far, far off base from reality: my model of how the voting public thinks led me to believe that Bush was un-re-electable in 2004, and that Rudy was a lock for the GOP nomination in 2008. My perception was that the electability argument cut against Clinton: she was a well-known bogeyman of the right and the press actively despised her (an especially critical dynamic going up against St. Barbecue). It was only my awareness of my own faint grasp on true electability that allowed me to put aside those worries and support Clinton.
So I think this makes me some sort of genious.
