The CNN/USA Today/Gallup poll of 1,018 adult Americans, including 778 likely voters and 926 registered voters, was conducted by telephone September 3-5.
Bush's convention bounce appeared to be 2 percentage points.
Incumbents have gotten an average bounce of slightly more than 6 points in previous elections, so Bush's apparent bounce seems small by historical standards.
Kerry got no bounce coming out of the Democratic convention, making Bush's movement appear robust.
Still, the 2 percentage point bounce could be illusory, since the poll's margin of error was plus or minus 3.5 percentage points.
