I would add eliminate “provisional ballots”. If you want to vote, you should take the time ahead of the election to assure that you are properly registered and know where to report to your polling place. Allowing someone just to show up anywhere is simply opening the door to fraud.
In a California precinct, a new election worker witnessed people all day long being told that they had requested a mail-in ballot. Because of this, these people had to vote provisionally. If the mail-in ballot had been accepted, it would be the one that counted. Most of these people said that they had voted on Election Day in person at all previous elections and had never requested a mail-in ballot. It seemed the common denominator among them is that they had had some recent dealings with California motor vehicles.
One more form of election fraud in the USA.
