Gallup reports today that President Obama’s post-Osama bounce in the polls has evaporated. According to Gallup, the President has a 46% approval rating in its tracking poll — exactly what he had before bin Laden was killed.

No surprise there. Bounces never last long.  But the successful mission in Pakistan will have lasting effects beyond the polling.  It will alter Republican messaging about President Obama’s foreign policy competency.  That can’t be measured in a tracker, but it will have a real consequence in the race.

That said, this may be the shortest bounce in memory.  The economy must be bad or something.
