I dont ever remember seeing them print a ballot right there for each person one at a time as they came to vote. Ive only been voting in presidential, gubernatorial and primaries since 2016 but have never seen this done.
Does anyone at all have any insight on this?
Of course. If they use pre-printed, pre-numbered ballots on special cardstock paper, that would be infinitely hard to cheat on.
Record everything. Record your arrival at the polling station. Record going into the booth. Record marking your ballot. Put your drivers license or other gov't ID w/pic in the recording at the same time. (If there's a 'control number' on the ballot, make sure that's in frame too.) Record turning in your paperwork. Record leaving the polling station.
When they cheat, and they're already cheating, your recording proves you 'have standing' for the inevitable court appeal, after bluehair judges start tossing the cheating case(s) for 'no standing'.
Just contact the suing attorneys to have your name, and recordings, added to the lawsuit(s).
