Despite the difficulty confronting Obama, an AP survey indicated the issue was hardly hopeless for the president, particularly in the Senate where Democrats maintain a majority, and perhaps also in the Republican-controlled House.
The survey showed 23 Senate votes in favor of military authorization and 10 more leaning that way. Opponents totaled 20, with another 14 leaning in the same direction, with the remaining 33 senators undecided or publicly uncommitted. That created at least the possibility of the 60-vote majority that will be necessary to advance the bill.
In the House, there were fewer than a dozen declared in support and 150 opposed or leaning that way. But 201 lawmakers had yet to take a public position, more than enough to swing the outcome either way.
The public opinion polling was daunting for the president and his team.
An Associated Press poll showed that 61 percent of those surveyed want Congress to vote against authorization of U.S. military strikes in Syria and 26 percent want lawmakers to support such an action, with the remainder undecided.
Adding to the uncertainty of the debate in Congress was a flurry of diplomatic activity that offered a potential way of achieving U. S. aims without military action.
Reacting quickly to a comment made by Secretary of State John Kerry in London, Russia called on Damascus to surrender control of its stockpile of chemical weapons and Syrian Foreign Minister Walid al-Moallem said he welcomed the proposal.
At the White House, Obama's deputy national security adviser, Tony Blinken, said the administration will "take a hard look at" the proposal. "We're going to talk to the Russians about it," he said noting pointedly that it comes in the context of threatened U.S. military action. "So it's even more important that we don't take the pressure off," he said, urging Congress to give Obama the authority he seeks.
Other officials sought to tamp down any suggestion that Kerry was making an orchestrated effort with Russia to avoid the strikes.
