Any lawyer will tell you there’s no substitute for a signed original with an original signature. Notaries public are still around and with good reason. Personally, I miss having a bank return an original check as proof positive that certain key payments were, in fact, made.
Despite all the problems with paper ballots, they’re still far more secure than electronic voting.
With paper ballots, punch cards you can have witnesses do the count and sign-off per precinct, doesn't take that long. With electronics you don't have hanging bytes.
