I don’t get the American obsession with voting “machines” of any kind.
Paper and pencil - done. Same as every other country in the world. This is one of those stupid parts of American exceptionalism that needs to be gone.
I guess if we absolutely insist on machines because god forbid the local TV stations can’t announce vote tallies by 10pm, then the scantron OCR machines are probably the best. Paper ballot, fill in the bubble as all US students have been trained to do since first grade. Optical scan, paper record, no code to hack really.
But maybe all those “consultants” slipping envelopes into officials’ pockets wouldn’t make as much money this way, so every county in every state has to create some bullshit infrastructure of their own.
