Just as an aside, in past elections, the evangelical church which served as the polling place for my precinct had a large Mexican flag hung on the wall in the meeting area. Absent was any counterbalancing American/Texas flag. That said a LOT about that church (which I would never attend just for that reason.)
The polling place I work is in a church ground level basement. A few years ago a picture of Jesus with little children was painted by the entry door. I still expect some offended progressive to complain about it, any election now.
The American flag is hung over the Hawaiian flag here.
Oddly enough, there is no Mexican flag.
