President Obama's approval ratings have bumped up to 51 percent, according to the latest Gallup tracking poll numbers. That suggests that he might be enjoying a small bounce due to the events surrounding the anniversary of the death of Osama bin Laden.

The last time his approval rating reached these levels was in May of 2011 when he broke 51 percent, after the successful completion of the mission.

Obama's numbers peaked at 53 percent in the last week of May, but then dipped below 50 percent in June.

His approval ratings sank to a low of 38 percent in October 2011, before returning to 50 percent in mid-April 2011.
