The bump that Obama received after the killing of Osama bin Laden in Pakistan has vanished completely, according to the Gallup Tracking poll

Obama's approval rating is now at 46%, equal to his approval rating in the last tracking poll conducted before Obama informed Americans of bin Laden's death. The poll also shows that 44% of Americans now disapprove of the job Obama is doing as president. According to the Gallup poll, Obama's approval rating crested at 52% after the bin Laden killing. His disapproval rating never fell lower than 40%. Obama's bounce is smaller in magnitude and shorter in duration than the bumps enjoyed by other presidents over the past 70 years, according to a study by Republican polling firm Public Opinion Strategies. For example, George W. Bush received a 15-point bump after the capture of Saddam Hussein in 2003 - a bounce that lasted seven weeks.
