But that, dear reader, is not their sole raison d’etre. Ever since the Rev. Jeremiah Wright launched his revenge tour over the weekend, the Clinton and Obama campaigns have inundated our inbox with press releases and news clips touting the candidates’ latest, greatest superdel endorsements. And the point, it seems, is not so much to prove that the contenders are inching closer to a magic majority as to show that, hey, white working-class people really like me. For Clinton, this is important because her whole candidacy is based on showing the world that white people like her more than Obama. For Obama, it’s important because everyone is saying she’s right.

So which candidate is winning this week’s superdelegate sweepstates? Whose superdelegates are the most Caucasian, most blue-collar, most swing state and/or Red State and most likely to trick the media into believing that Obama or Clinton is, like, totally down with Bubba? Here’s a handy (and completely arbitrary) scoresheet–complete with our patented Bubbameter ®–to help you keep track:

OBAMA’S SUPERDELEGATE SWEEPSTAKES SCORE: 289; six endorsements

There you have, folks: it’s Obama by a farmer. Unfortunately, the timing of these announcements is mostly for show. Yesterday, sources told the Politico that “while more than 80 Democrats in the House and Senate have yet to state their preferences in the race for the Democratic nomination… most of them have already made up their minds and have told the campaigns where they stand.” Which way have they already gone? Since March 4, Obama has lost every major primary, but he’s still managed to capture 41 superdelegates to Clinton’s nine. He’s even beating her 9-4 in the post-Pennsylvania cagematch. And that trickle is likely to continue. Asked how the “secret” superdelegates are leaning, Sen. Claire McCaskill of Missouri–who has endorsed Obama–quoted the Godfather of Soul. As “James Brown would say,” she quipped, “‘I Feel Good.’”

Could a series of strong Clinton finishes sway the non-Congressional superdels? Has Wright wronged Obama? Tune in next time for another round of the Superdelegate Sweepstakes.
