Asked to pick a response to stop the killing of civilians in Syria, just 15 percent in the poll say they favor U.S. military action, and only 11 percent want to provide arms to the opposition.

By comparison, a plurality of respondents — 42 percent — prefer to provide only humanitarian assistance, and 24 percent believe the U.S. shouldn’t take any action.

Perhaps more significantly, those attitudes cut across party lines and almost all demographic groups.
