I’s even bigger than that, in my opinion.
Every false vote is effectively nullifying the vote of someone else. Many people have fought and died to secure our right to vote, and to me this makes voter fraud on the same level as treason during war time. Therefore, the penalty should be similar.
I would fully support imposing the death penalty for intentional voter fraud.
I would imagine that once people are arrested, convicted, and the sentence carried out, that would pretty much put an end to it.
But I truly believe the crime is that serous.
