Clinton voted against a Senate measure Thursday that condemns MoveOn.org.
WASHINGTON (CNN) - The Senate overwhelmingly voted to formally condemn the liberal organization MoveOn.org Thursday for its recent publication of an ad questioning the credibility of the top commander in Iraq Gen. David Petraeus.
Twenty Democrats joined the Republicans in the 72-25 vote that officially repudiates the group's ad. Sen. Joe Lieberman, an Independent from Connecticut, also voted for the measure, sponsored by Texas Republican John Cornyn. (Related: Bush: MoveOn.org ad on Petraeus 'disgusting')
Sen. Hillary Clinton, D-New York, who has been criticized by several Republican presidential rivals for not formally distancing herself from the organization, voted against the measure.
As for the other 2008 Senate Democratic hopefuls, Chris Dodd of Connecticut voted against the measure while Barack Obama ofIllinois and Joe Biden of Delaware did not vote.
Republican National Committee Chairman Mike Duncan issued a statement highly critical of both Clinton and Obama shortly after the votes were cast.
“Senators Clinton and Obama need to decide whether they’re running for America, or running for MoveOn.org," he said. "If Clinton and Obama cannot bring themselves to take a stand against a vicious attack on the man leading our forces in Iraq, why should American voters believe they are capable of demonstrating the leadership we need in a Commander in Chief?”
Former Massachusetts Gov. Mitt Romney was also highly critical of Clinton, saying in a statement her vote raises questions over whether she would be a "credible commander-in-chief."
"Hillary Clinton had a choice," he said. "She could stand with our troop commander in Iraq, or she could stand with the libelous left wing of her party. She chose the latter.
"The idea that she would be a credible commander-in-chief of our armed forces requires the willing suspension of disbelief," he added, a reference to Clinton's comments to Petraeus at a recent Senate Armed Service Committee hearing in which she said his upbeat assessment of conditions in Iraq required "the willing suspension of disbelief."
Meanwhile, MoveOn.org Executive Director Eli Pariser said of the vote in a statement, "No wonder public approval of Congress is tanking. They’re so out of touch with reality that they can find time to condemn an ad but they can't do what most Americans want – vote to end this war."
