Gallup: Obama's approval rating has decreased among all six partisan/ideology groups Gallup tracks on a regular basis since January, but it has dropped the most -- 10 percentage points, from 40% to 30% -- among pure independents. These are the roughly 14% of national adults who neither identify with one of the two major parties nor indicate a leaning. Obama's approval rating has declined by nearly as much -- eight points -- among moderate/liberal Republicans, from 29% to 21%.
Obama's approval rating has changed the least in 2011 among the two groups on the far left and right of the U.S. political spectrum. Most liberal Democrats and very few conservative Republicans approved of him in January and this remains the case today.
