“To make progress, we must rise above the partisanship and the issues that divide us to find common ground. We must move the country in a dramatically new direction," Bingaman said in a statement released by the Obama campaign. “I strongly believe Barack Obama is best positioned to lead the nation in that new direction.”
Bingaman is one of the party's nearly 800 superdelegates who will decide which candidate wins the Democratic nomination. Clinton's current superdelegate lead over Obama is now just over 20, though more than 300 have yet to announce who they will support.
