I don't know why I would live in a community where this is the case. Be assured that it is a no-where-near universal proposition.
I have had local political signs from time to time, Congressional primary, judge, prosecutor...but never a presidential election sign.
At this point, since I live on a dead-end private road, there's no reason for any sign. Regardless, no candidate in this presidential election excites me enough to going looking for a sign.
Its not my community that bothers me. It is what drives through it. In the 15+ years I've been here, the only issue I've had is because of the previous tenants.
