Appearing on MSNBC's "Morning Joe" Tuesday morning, Tom Brokaw dropped a bombshell on Terry McAuliffe, Hillary Clinton's campaign chairman.

"Somebody very close to the Obama campaign told me yesterday that they've got 50 [superdelegates] that they've identified who are ready to go public before too long," Brokaw said. Off-camera, someone else from the show (it sounds like host Joe Scarborough) can be heard exclaiming, "Wow." Video of Brokaw's remarks appears below.

If this is true, it would represent a major coup for Barack Obama's campaign. The Associated Press' delegate count has Obama and Clinton separated by just 100 total delegates, included pledged and superdelegates. Obama leads in that count with 1,378 delegates; Clinton trails with 1,276. For the moment, 2,025 are needed for victory.
