DeWine lost by 12% (56-44%) in 2006. The margin was nearly 453,000 votes. The final RCP average for the race had it at 53.3% to 43.3%, which ended up being pretty close. Nobody besides Zogby had DeWine above 45% after September.
As far as Ohio polls are concerned, the University of Cincinnati poll was the most accurate in 2004, coming within less than 1% for both Bush and Kerry.
So what is that poll saying this time?
thanks for the update
