Obama picks up Iowa superdelegate

From NBC's Domenico Montanaro
Richard Machaceck, an Iowa DNC member and superdelegate, has endorsed Obama, according to a report by the Des Moines Register, passed along by the Obama campaign. This is Obama's second superdelegate of the day.

"I think it needs to be over, and in good conscience, I can't fly in the face of my precinct, county and district," Machacek told The Des Moines Register. "The raw numbers coming out of the district conventions really sat me down hard."

This makes it 7-3 superdelegate pickups for Obama since the Pennsylvania primary.

SUPERDELEGATES: Clinton 265-244 (286 uncommitted)
PLEDGED: Obama 1,490-1,334

OVERALL: Obama 1,734-1,599
