Funny isn’t it. Whenever there are reports of machines switching votes, it’s always a republican who notices and complains... My concern has always been what gets sent from the machine to the main computers where totals are created. There is such an opportunity to alter the counts from each machine during those tabulations
I voted in SC, and did not have a problem with my vote changing, but I did notice the touch screen was not very responsive. For some boxes, I had to press repeatedly to get it to record.
