1. Do you agree that absentee voting already provides a loop hole by which votes /could/ be bought?It would be a foolish person who accepted a video or photocopy as proof of how you voted. It would be easy to change your real vote after recording this sort of evidence, or to doctor the evidence. But your scheme provides posession of a "Unique Ballot ID" number and a way to verify how that vote was officially cast after leaving the polls.
