re: Do you support mail ballots for the election?

Yes if you registered properly for it and then received a coded ballot. Then you mail it in with whatever vote you want to cast. The kicker is that each ballot has a unique identifier so if there were 2 of the same identifiers then the ballot was copied and both of those votes are set to the side.

Could easily be done across the nation so no matter how many falsified votes there are, they would get caught and not counted.

Yes, it would take too long to implement.
