I do not know if, or how much, the presence of political yard signs has to do or is predictive of the outcome of an election.
But, here in Piqua, Ohio, part of John Boehner’s 6th CD, and an area that historically votes 65% Republican, the population of “Obama/Biden” yard signs is up over 1000%. Four years ago it was extremely rare to see an Obama sign – anywhere. Yesterday, I counted five of them on about half of South Street alone and Boone Street has a bunch. I’ve not driven all over town, but counted these as part of my regular travels.
Hopefully, this is good news for President Obama.
