The Obama administration is hoping to tamp down a growing chorus of skepticism on Capitol Hill toward military action in Syria -- skepticism that was punctuated Thursday when more than 170 House lawmakers signed a letter demanding congressional approval for any military action.
And while Congress remains deeply unpopular, polls find Americans have remained overwhelmingly supportive of requiring presidents to win its approval for military intervention overseas.
No major polls have asked about requiring congressional authorization on Syria, but in 2011 more than six in 10 registered voters in a Quinnipiac University poll (62 percent) said President Obama should have requested approval from Congress before authorizing military force in Libya.
The Libya intervention was unpopular, and the public's desire for oversight predates Obama and stretches back at least as far as the 1970s.
A 2008 Gallup poll found nearly eight in 10 Americans (79 percent) saying the president "should be required to get approval from Congress before sending United States armed forces into action outside the U.S." That opinion was nearly identical to 1973, when 80 percent supported requiring such approval.
Obama's predecessors have also faced a public desire for this check on presidential power. Seven in 10 Americans said George W. Bush should get Congress's sign-off before taking action in Iraq in a fall 2002 CBS News/New York Times poll, just before Congress authorized the use of force.
In a striking parallel, a USA Today poll 12 years earlier found 69 percent saying Bush's father, George H.W. Bush, needed congressional approval before taking action in Iraq. Big majorities also said President Bill Clinton should get approval for military action in Bosnia and Kosovo.
There are some exceptions. The 2008 Gallup poll found most Americans thought congressional approval was not necessary if the United States were attacked or if American citizens were in danger or in need of rescue. The public was split on requiring consent to respond to a natural disaster.
More relevant to the Obama administration's plans in Syria, three-quarters of Americans said congressional approval should be required even if the president did not expect a long combat operation.
Obama finds himself in an unenviable position with regard to Syria, having said the Syrian regime would cross the so-called "red line" if it used chemical weapons on its own people -- something Vice President Biden said there is "no doubt" occurred.
Despite reports of a potential decision on action as early as Thursday, such action has not occurred. And British Prime Minister David Cameron on Thursday succumbed to a vote in Parliament against such use of force against the Syrian government.
Obama, it appears, struggles with similar hesitation in the American Congress, much of which is demanding a vote.
