Pew poll: Public Remains Opposed to Arming Syrian Rebels
There is very little partisan divide in attitudes about the conflict in Syria. Majorities of independents (74%), Republicans (71%) and Democrats (66%) oppose the U.S. and its allies sending arms and military supplies to anti-government groups in Syria. Overall, 70% oppose the U.S. and its allies sending arms and military supplies to anti-government groups in Syria; just 20% favor this.
At the same time, the public does not reject a key argument for involvement in Syria: by a 53%-36% margin, most agree that it is important for the U.S. to support people who oppose authoritarian regimes.
The public is divided over whether the U.S. has a moral obligation to do what it can to stop the violence in Syria: 49% agree, 46% disagree.
By a 58%-38% margin, more Democrats agree than disagree that the U.S. has a moral obligation to do what it can to stop the violence in Syria. Republicans are split with 49% saying the U.S. has a moral obligation to do what it can to stop the violence, and 48% saying it does not have this responsibility.

The opposition to sending arms to the rebels is bipartisan with republicans, surprisingly, opposing the idea slightly more than Democrats. There is more of a partisan split on whether the US has a moral obligation to do anything about the violence there. Of course, history shows that republicans don't spend a lot of time worrying about reducing violence anywhere, at home or abroad.
