We need to go back to the old “pull the lever” type system. Less likely to be rigged.
Back in the Carter years, those very machines were discovered to be *pre-loaded* w/Carter votes.
The touchscreens tell you what it has recorded and you can go back and change. It also has a confirmation screen and the ones we use have a scrolling paper record on the left hand side that can also be checked.
I think every type of process can be subverted. Bags of ballots were *found* back in Chicago and in Texas for JFK and LBJ, IIRC.
