Impose a thousand dollar fine and sixty days in jail for voting on a dead person’s behalf and the shenanigans will end.
If someone wanted to make it a capital crime I would not object.
To be effective any punishment for vote fraud needs to primarily deliver the consequences to the candidate or candidate's organization that organized it. Maybe a life time ban from politics might be appropriate for the candidate and his/her minions as well as permanent loss of the voting right.
“Impose a thousand dollar fine and sixty days in jail for voting on a dead persons behalf and the shenanigans will end.”
Isn’t it already a felony?
Just enforce the punishments that exists instead of ignoring infractions.
