PRINCETON, NJ -- The final Gallup 2008 pre-election poll -- based on Oct. 31-Nov. 2 Gallup Poll Daily tracking -- shows Barack Obama with a 53% to 42% advantage over John McCain among likely voters. When undecided voters are allocated proportionately to the two candidates to better approximate the actual vote, the estimate becomes 55% for Obama to 44% for McCain.

The trend data clearly show Obama ending the campaign with an upward movement in support, with eight to 11 percentage point leads among likely voters in Gallup's last four reports of data extending back to Oct. 28. Obama's final leads among both registered voters and likely voters are the largest of the campaign.
