Same thing here in my neighborhood in eastern Wa State. 76 houses in this development, exactly one sign (Romney). It is actually the only Romney house sign I have ever seen. Earlier there were a couple of Herman Cain signs. There were a scattering of Obama signs in 2008 but not now.
I've stopped having stickers on my car because I think the cops can find you faster if you have identifying marks on your car, not that I've done anything wrong....LOL
