Obama gets another superdelegate

Barack Obama won another superdelegate endorsement today, increasing his haul even since losing the Pennsylvania primary last week and narrowing Hillary Clinton's edge among the party leaders and elected officials who will likely determine the Democratic nominee.

Clinton narrowly won the New Mexico caucuses on Feb. 5, but Senator Jeff Bingaman went for Obama.

“Our nation faces a daunting number of critical challenges: reasserting America’s leadership in the world, meeting our needs for energy independence, addressing global warming, making healthcare accessible and affordable, positioning our economy to effectively compete globally, and extricating ourselves from the war in Iraq, to name a few," Bingaman said in a statement issued by the Obama campaign. “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."

Obama leads among all delegates, 1,724.5 to 1,593.5, according to the latest Associated Press tally.
