Well in all fairness, if my neighbour was a politician, I'd put up a poster of the opposite party just to annoy him.
I'd on the other hand be very happy to be living next door to a politician, because it would be a sign that I'd really "made it", that I could afford to live in a beautiful area far from crime, far from bad schools, far from council estates............you know, far from people who actually have to live amongst the results of the policies these's put in place
