I live in a fairly liberal upper middle class neighborhood. It is the kind of place where adults attend children's birthday parties wearing Obama tee shirts. You notice things around here. Obviously, every other car it seems has an Obama sticker on it. I especially love the big SUVs and minivans decrying an oil war. Living near a university campus, I see lots of Ron Paul stickers.
There is one house in my neighborhood with a "Hillary for President" sign in the window. This house also sports (in another window) an etching of Elvis Presley on glass. This morning I noticed that next to the Hillary poster, there is a lifelike bust of Elvis in the window.
I am sure it means something, but I fear what that answer will be.
