Race and gender? Nope.

According to CNN exit polling in Virginia, Obama effectively split the white vote there, garnering 48% to Clinton's 51%. Along gender lines, surely Clinton had the advantage, though, right? Wrong: 58% of women voted for Obama compared to Clinton's 42%.

On issues such as the economy, the establishment Democrat definitely had the advantage, right? Wrong: People for whom our economy was a major concern voted 60% in favor of Obama.

So much for the spin machines and Beltway punditocracy.

After tonight, there will be a lull of a few weeks before contests in Hawaii and Wisconsin. The superdelegates have to be very, very nervous.
