The increasing reach of ISIS on the ground in Iraq and Syria may be changing how Americans view the U.S. role in that battle.  However, even though a majority of the public believes the U.S. needs to do something about the ISIS threat in Syria, most Americans put limits on what that something should be.  There is still relatively limited interest in sending in U.S. ground troops.  Two in three support air strikes, an option that received about the same amount of support last year. 

Republicans are more likely to support both these options than are Democrats and independents. More than six in ten Democrats favor airstrikes, compared with 80% of Republicans.  Nearly half of Republicans would support sending ground troops, something only a quarter of Democrats would favor. 

But there is more support now than there was last summer for sending weapons to the moderate rebels in Syria, presumably in the hope that they could confront both ISIS and the government of Bashir al-Assad (whose personal favorable rating in this poll is just 9%).
