So says Gallup:
-Nov. 21, 2009: 48 percent
-Nov. 21, 2010: 47 percent.
Given that Gallup's tracking poll has a margin of error of four points, it's entirely accurate to say that Obama's approval rating today is the same as where it was one year ago.
You wouldn't know it from reading Obama's doomsday press coverage this year, though.
FYI: At this point in their first term, both Ronald Reagan and Bill Clinton posted 43 percent approval ratings, according to Gallup.
