In my own neighborhood, while we previously never discussed politics, suddenly right before the election, my neighbors next to me and across the street put “Trump 2020” yard signs up. My neighbors still have their Trump signs up and we are now part of a neighborhood watch, rather than just unknown people living in the same neighborhood!
So my answer as to what to do about the Trunpites next door....they became part of our “Got Your Back” neighborhood protection system.
