I reported this last week as a possibility, but now it seems to be happening: a movement among North Carolina Democratic congressmen to consolidate in support of Barack Obama. The Wall Street Journal is reporting that:

North Carolina's seven Democratic House members are poised to endorse Sen. Obama as a group -- just one has so far -- before that state's May 6 primary.

The entire delegation had been pledged to John Edwards for the greater part of the primary campaign. When he suspended his campaign, all the members received calls from the other camps. As the WSJ says, only Rep. G.K. Butterfield had switched his support to this point.

The mass endorsement is significant beyond its potential effect on the NC primary. All seven congressmen are also superdelegates.

Update -- The Raleigh News & Observer has a quote from the Obama campaign which makes it clear that this thing might still be in the works:

"We're pleased to have the support of Rep. Butterfield and are working to earn the endorsement of his colleagues in the N.C. Congressional delegation," wrote spokesman Dan Leistikow in an e-mail to Dome. "Despite the Wall Street Journal's optimism, none of them has (told) our campaign that they are ready to announce their endorsement of Senator Obama, so we'll keep working on it."
