I know yard signs are no exact signal of how an election will go over...but 4 years ago their were NO Bush signs...and now...except for the area right near Cleveland...McCain/Palin signs are stuck in every yard, lining roads, ect.
Same in my area Lake County. I get tickled when I'm driving to work or , Just running errands and I see Mccain leading in yard signs about 4-1, and then I see some poll saying Obama is up by 7 or 8 points in Ohio it makes me confident that his poll numbers are proably inflated. Even a big time Obama supporter at work noticed she asked who I thought was going to win the election and I said proably Obama and she said she was worried because all she saw was Mccain/Palin signs.
My area votes with the statewide winner 99% of the time. I'm 98% certain based upon what I see and hear Mccain will carry Ohio.
