24 Hours Till Votes Are Counted, Missouri Is Still Tied, Could Go Either Way: McCain 48%, Obama 48%, in SurveyUSA's final tracking poll of Missouri, released Election Eve. No change since an identical SurveyUSA poll 1 week ago. Research, underwritten by KMOX radio in St. Louis and KCTV-TV in Kansas City, has McCain up by 25 points in the Ozarks, up by 22 points in the boot-heel, and up by 11 points along the Iowa border. Obama leads by 16 points in greater St. Louis and by 10 points in greater Kansas City. The more younger voters who turn-out, the better Obama's chances. The more older voters who turn-out, the better McCain's chances. McCain must win Missouri to be elected President. Obama would like to win Missouri, but has many paths to 270 electoral votes that do not include Missouri's 11. 800 adults interviewed 10/30/08 through 11/02/08 yielded 754 registered voters and 674 likely voters.
