I've never seen a Dominion owned or manufactured 'voting machine'. I had no idea what they look like. I looked 'em up with Google images. Still haven't seen one in action - I'm guessing they are touch screen tech.
At my voting location - after establishing your identity and residence and voting eligibility - an election judge hands you a ballot with small circles printed next to candidates names for their various positions or offices they are campaigning for and you have to use a black ink pen to fill in the 'entire' area inside those small circles.
Apparently the marking pens can't be blue ink or felt-tipped pens nor pencil lead. Of course, this is in backasswardsville - so maybe the judges were just being smallville hicklets with their instructions to me.
You then take your appropriately marked up and finished ballot to a tabulating machine which resembles an office copier which phototronically reads your marked selections on the ballot which you yourself must insert into the vote tabulator.
Unless it is equipped wirelessly to transmit those records elsewhere - I fail to see how those particular units could be hacked or tampered with as I know the building where this occurs and I did not notice any cabling ran to the tabulator besides a power line which was plugged into a wall.
A judge told me that the tabulator stores all the votes gathered, electronically on a thumb drive for ease of transportation. I assume this particular model must also have an internal SSD or hard drive to record data to, as well.
In the future, I hope to see the newer Dominion voting screens installed everywhere with their manufacturing name proudly displayed, so as to trigger future MAGA - or perhaps even turn them away from their voting precinct 'in protest'.
The same GQP demanding we move on from January 6th, 2021 is still doing audits of the November 3rd, 2020 election.
