They do that here in Virginia. I thought it odd that someone was putting a McCain/Palin sign IN their car and not taking it out of it until I realized (too late) what they had done. Signs are up one day and gone the next-but it’s always Republicans signs that disappear.
I’ve been seeing Fimian signs up for *months*. I’m sure you’re right, but if any of the ones that I see on my commute route are disappearing, then they’re replaced the same night.
