You need to get him off the rolls. I bet you could find he has voted in several elections.
I will. When he ran for a certain political office in our neck of the woods, we requested and got a list of all registered voters. I was really surprised how many dead people, people that had moved, people at addresses that didn’t exist, were all listed. We were told it just takes a little time to “catch up” on the registrations. But he’s been gone for nearly 10 years!
Also, at least here in NY, we can have poll watchers. It’s not going stop outright fraud if someone comes in and gives a name that’s seems registered correctly, but I was able to check my list and make sure they weren’t dead people or at questionable addresses. This also helps
because you write down the names as they vote, report back to Republican headquarters and they call those people that say they support
you and get their butts out the door to vote. Worked every time.
In his first local election we made sticky labels of every eligible voter. He knew just about everyone so when a list of names came in he’d say which
side to put the stick label on(D or R). At the end of the night he won and was only 22 people off from the correct vote tally!
