It's official: President Obama got a nine-point bounce in his approval rating after killing Osama bin Laden. That's more or less in line with the historical average for U.S. presidents after a major national security event, at least according to Public Opinion Strategies, which supplied the interesting chart above (the exception, George W. Bush's 35-point surge after 9/11, was excluded from the average). Nine points actually strikes me as a bit low -- especially given Bush's huge jump. But the number that really jumped out at me was Franklin Delano Roosevelt's paltry bounce of 11 points after Pearl Harbor. What gives? I thought that back in the olden days people rallied around the flag and supported their commander-in-chief after an attack. And even the not-so-olden days, as Bush's numbers attest.
