I think if that happens at a poling spot all the votes are voided and those that did vote should be contacted to recast the ballot... I think it more likely vote rigging then a calibration problem.
There’s Youtube videos demonstrating the calibration error...peculiar how this “error” always results in votes for Democrats.
What if everyone demanded to vote on paper? Some states/counties only have the machines, however all are required to have provisional ballots. What if you demanded to vote on the provisional ballot and at the time of voting proved your right to vote? What are the issues that might arise?
What the heck is a “calibration error” anyway? Sounds like some kind of backdoor built-in cheat designed to give plausible deniability to the cheaters.
What is there to calibrate? When I was a kid in school we took all kinds of tests (including the SAT) using those forms you had to use a #2 pencil to fill the bubble of the correct answer. I remember a lot of kids very upset about their grades, but I never heard anyone explain their results owing to a “calibration error”. This is one of the simplest things to do. Just count the ballots. Not a lot of code.
So many computer systems doing so many things for us. Do ATM machines have calibration errors? I had to take my DMV written renewal test on a computer. How many people failed their DMV tests due to calibration errors?
