ABC News’ Karen Travers Reports: For the first time this campaign season, Barack Obama has surpassed Hillary Clinton’s support among superdelegates, according to the ABC News delegate estimate.

Sen. Obama, D-Ill., picked up two superdelegates this morning giving him a new metric to tout in addition to his current commanding leads in pledged delegates, popular votes, states won, and money raised.

 Rep. Donald Payne, D-N.J., switched his endorsement from Clinton to Obama and Rep. Peter DeFazio, D-Ore., endorsed Obama. DeFazio was previously uncommitted.

UPDATE:  The American Federation of Government Employees endorsed Barack Obama today.  AFGE President and superdelegate John Gage said “[o]ur people, I think, recognize the enthusiasm and vitality behind Senator Obama’s campaign.”  Gage was uncommitted, but to day also personally endorsed Barack Obama for President adding one more to Obama’s increasing superdelegate total.

California DNC member Ed Espinoza endorses Barack Obama for President.
