Why are they concerned ? They have controls in place to make sure it wont happen.
When the minority groups all start voting for the GOP the DNC might wise up.
Yeah, they will just kick out poll observers in Milwaukie/Detroit/Phoenix/Atlanta and count until Biden or whoever these losers run gets enough “votes.” Dems at this point simply commit crimes and fraud in the open and their media doesn’t report it as their DOJ ignores it.
