I was thinking that perhaps the lack of Biden signs are out of fear. Fear of retribution by the fanatical side of Trump supporters if he wins or loses in November. It certainly seems to me, that there are FAR more fervent Trump supporters than fervent supporter of any liberal ideals that exist right now. It's been my experience over the last 4-5 years, that you really can't get anyone to change their views anyways. For me personally, this American [[and Global) era we're in feels very much like the fascism from the 1930's based on what I have read and watched.
