Systematically telling the registered members of one party they have already voted is a glitch?How about requiring that mail-in ballots be requested and then maintaining strict chain of custody for them? That seems like a lot better failsafe to me.
How about no more mail in ballots? We used to have Absentee Ballots, available by request, and limited in their availability to those with a reason for not being able to be at the polls in person.
As long as Americans lack the courage to go vote in person (be it COVID or whatever the terror
du jour that stops them) our country will continue to be ruled (yes,
ruled) by people who brazenly exploit that fear to gain and retain power.
