The picture above is a voting machine in New York. I don't know how old the picture is, but the same voting machines are in use now.
And I don't think they have built these machines since like the 1930s. Our polling place had two, one of which was broken the whole time.
And you can (or probably cannot) imagine how slow the line moves with one mechanical machine. It was asinine. And New York has no absentee requests like California has.
It was very frustrating.
