SurveyUSA interviewed 900 Ohio adults 09/12/08 through 09/14/08. Of the adults, 832 were registered to vote. Of the registered voters, 692 were determined by SurveyUSA to be likely voters in the 11/04/08 general election. Like other research firms polling in Ohio, SurveyUSA did not mention Bob Barr or Ralph Nader by name in this questionnaire. Barr supporters would have been able to say they supported "another candidate" when asked to choose between McCain and Obama. If Barr's support is understated here, McCain's advantage is overstated. Interviews conducted after federal bailout of Fannie Mae, but before bankruptcy of Lehman Brothers. Interviews conducted after most, but not all, of ABC News' interview with Sarah Palin had been broadcast. Ohio has 20 Electoral College votes. George W. Bush carried Ohio by 2 points in 2004 and by 4 points in 2000.
