It is interesting that people "vote" via lotto machines -- millions every week -- and there are so few charges of fraud or incompetence. One key might be that lotto machines print a ticket with a serial number, date, time, and validation number.
Crooked voters/officials need to be stopped from permitting ballots that are "genuinely" counted yet granted for false purposes.
Also the penalties for those who cheat at Lotto are higher than for those who cheat at politics. Few ballot stuffers are prosecuted to the full extent of the law.
