The final SurveyUSA poll of Missouri. Dead even: Obama 48%, McCain 48%. Late Update: Final SUSA Ohio: Obama 48%, McCain 46%. From the poll release: "In Ohio, Early Voters May Give Obama Enough Running Head Start That McCain Can't Catch Him on Election Day: Barack Obama 48%, John McCain 46%, in SurveyUSA's final tracking poll released Election Eve. Obama leads 5:3 among those who have already voted. McCain leads 5:4 among those who have not yet voted. Obama led in the past 3 SurveyUSA tracking polls, but by tapering margins. Obama led by 5 on 10/14/08, by 4 on 10/28/08 and by 2 today. It is possible that McCain could overtake Obama in the final 24 hours, but that would require young voters to stay home on Election Day and white voters from Dayton, Cincinnati and along the West Virginia border to show up in larger numbers than they have so far indicated."

Wrong. Here are two polls on Oct 31, 2004. Final CBS News poll shows Bush up 3% over Kerry: http://www.cbsnews.com/stories/2004/10/31/opinion/polls/main652496.shtml and also shows Bush over Kerry 51% to 43% among already voted. Final Pew Research poll shows Bush up 3% over Kerry: http://people-press.org/report/232/slight-bush-margin-in-final-days-of-campaign and also shows a virtual tie (48% Kerry vs 47% Bush) among already voted.
