As of Monday, Mr. Obama’s approval rating in the Real Clear Politics average of polls is 48 percent, and his disapproval rating is 47.5 percent. One month ago — on Feb. 12 — those numbers were 48 percent and 47.2 percent, respectively. So this average of polls has shown almost literally no change.
Or you can look at the average from the Huffington Post Pollster chart, which gives you a lot of flexibility in how you calculate the average. You can choose more or less sensitive settings, and you can choose to include or exclude certain pollsters. In the various versions in the chart below, I’ve used the different sensitivity settings and run versions with and without Gallup and Rasmussen Reports, which track Mr. Obama’s approval rating daily and therefore tend to dominate the trend line under this particular method.
But the story is basically the same. The most aggressive settings show Mr. Obama’s approval rating having declined by about one point. The more conservative settings instead show it increasing some. There just hasn’t been a lot of difference.
