Gallup reports:

A new USA Today/Gallup poll finds nearly half of Americans saying the U.S. troop surge in Iraq, now over, has made the situation there better, up from 40% in February and just 22% a year ago. Accordingly, the percentage believing the surge "is not making much difference" has declined from 51% a year ago, and 38% in February, to just 32%.

Gallup also notes: "Americans' views about the surge have been, and remain, highly politicized. However, all three partisan groups -- Republicans, independents, and Democrats -- have grown more likely since February to believe the surge is helping."
