Gallup: Obama/Biden 49%, McCain/Palin 43%

Comparing Obama's current 49% support with the 45% he received immediately before the start of the Democratic National Convention in Denver last week suggests he received a 4-point bounce out of the convention, fairly typical of past convention bounces. Aside from the past few days, Obama has only once previously attained 49% support from national voters, and that was in late July. (To view the complete trend since March 7, 2008, click here.)

The determination of this year's Democratic convention bounce is complicated by the fact that McCain announced his pick for vice president -- Alaska Gov. Sarah Palin -- on the first morning after the convention, thus diverting considerable media attention to the McCain campaign that otherwise would have been focused on recapping the Democratic convention and Obama's Thursday night acceptance speech. However, even using Friday's Gallup Poll Daily tracking report as the indicator of Obama's convention bounce produces the same result. Obama was preferred by 49% of registered voters in Gallup Poll Daily tracking from Aug. 26-28, after the Democratic National Convention was underway, but before the Palin choice was made public.
