If a would-be voter wearing blue jeans & a camo shirt walks up, then smiles at the gun-toting losers who smile back, what message is sent?
If a would-be voter wearing long scraggly hair, darker skin tones, or climbing out of a smoking beater of a car grimaces upon sight of the gun-toting losers who grimace back, what message is sent? What if the voter gets out of a shiny new Volvo carrying a Save the Earth tote bag? She doesn’t grimace at the fascists; instead she looks surprised / fearful & gives a shudder as she passes.
The intimidators don’t hang out at precincts where an overwhelming R majority is a foregone conclusion. They hang out at precincts where a few percent of voters turned away makes a difference.
Note that that turning away may not happen at the door. It may happen hours or days earlier when news spreads that fascists have staked out most or all the early voting locations in the county.
