My neighbor who stays right below my apartment used to have a "McCain/Palin for 2008" message on a small greeting card sized poster on their door until recently. Since last week, they have decorated their entire door with Halloween stuff and creatively painted one half of the door with black and other with orange. The black part has all obama photos and says "trick" and the orange part has mccain photos and says "treat". If it is an original idea, I think it is really creative, irrespective of whether I agree with them or not.
