Another day, another former chairman of the Democratic National Committee has endorsed Barack Obama. Today, it's Paul Kirk, Jr. A pillar of the party and one of the elders we're always writing about, he may help other undecided superdelegates sooth their wedding day jitters.

UPDATE: Apparently, Kirk has been a supporter of Obama's for a while. So this isn't so much new as it is an attempt to perpetuate the idea of momentum.
