PPP surveyed 792 Ohio voters from August 11th to 14th. The margin of error for the survey is +/- 3.5%. This poll was not paid for or authorized by any campaign or political organization. PPP surveys are conducted through automated telephone interviews.
PPP is a Democratic polling company, but polling expert Nate Silver of the New York Times found that its surveys in 2010 actually exhibited a slight bias toward Republican candidates.
