A voting machine is not a computer and is not hooked to the internet. We had a few (2-3) machines screw up in Texas and took them off the voting line. The voter saw the problem, did not punch the “vote” button but told the judge and the machine was taken off line and voter voted on another machine.
I understand what you are saying. Did the polling station contact the prior voters who happened to use that machine to come back in and recast their vote?
