Have you tried to have his name removed?
When I moved states, I made a point to get it in writing and also rechecked online to see if I appeared to still be listed or not.
...fyi, when I moved to TX from So CA, I saw I was still on the County rolls and asked to be removed three times, was assured it was done and then still got a voter guide mailed to my address in Texas. The Dems do what they want and could care less since there are NO consequences. And I was an election judge for the previous six years... ymmv
