I’ve never voted on a machine - always on paper with a pen. When I was a kid, I remember going into a voting booth with my mom, and she pulled some levers to vote. I think those are very rare nowadays. I do remember there being some discussion of touch-screen voting machines having the standard touch-screen problem of mis-noting your touch slightly as they age (I’ve especially noticed this on ATMs) and thereby seeming to record the wrong vote. I’m not sure how common these are. And of course, there are machines that optically read paper ballots and count those votes, but that voters never personally interact with.
So now, in 2020, there’s a bunch of crazy conspiracy theories about the voting machines made by Dominion, particularly in Georgia. But I’m totally unclear on what kind of machine these are. Are they tabulators? Or did Georgians actually vote on these machines? And if the latter, are they touch-screens, or some other interface?
