There seems to be a CW here that the 9/11 anniversary always gives Baby Bush's numbers a little bump. But does that hypothesis hold up under scrutiny? I decided to take a look at compilations of his post September 11 approval ratings for the years 2002-2005. The polls here are from CBS News/NYT, Gallup/USA Today/CNN, Zogby, PEW, Newsweek, Fox, AP/Ipsos, Harris, ABC News/Washington Post and NBC News/WSJ. In each case I have taken the most immediate pre-911 poll for the given year for each news organization/pollster and juxtaposed it with the most immediate post 9/11 poll for the year, for that news organization.

ConclusionThe overall 9/11 anniversary effect has been negligible for Bush's popularity since 2002. There was a small increase in his approval ratings during the one year anniversary in 2002, but even this was within the margin of error. In subsequent years the movement in his polling numbers has been even more negligible, falling within the margin of error, either positive or negative.
