Important to note
Some states (mine included) will have nothing to do with voting by machine, and use hand-marked paper ballots, which are optically scanned, and then saved in case a manual recount is necessary.
Please note that technology is used where it provides a benefit (fast optical counting of ballots) and NOT where it is a significant risk (recording of the actual vote). Whether this seemingly obvious distinction is ignored due to malice or ignorance in other states is left for others to decide.
