OK, thanks Mike, but I don’t think I need the help here. Think about what you said. “So what if people move.” Actually many of the “moved” moved out of Georgia and now reside in another state. It’s not like they just moved up the street. Such a move would require them to re-register in their new State of residence (in theory this would apply at the County level as well) and be removed from their previous states voter register. Except people don’t do that. They may register in their new State (or County)of residence, but advising their previous State of residence that they have moved is rarely done.
Another portion of those removed from the voter registration were people who had passed away. In most states they make no effort to match the public record of the recently deceased to that of the public record of registered voters. I had that experience myself. Following the passing of my father a while back I continued to receive mail-in ballots for him. That tells me that I could have voted my thoughts on his ballot and no one would have known. Instead though I called the local registrar of voters and, after jumping through some bureaucratic hoops had him removed. (I didn’t have to prove he was alive, but did have to prove he was dead.) This is not a unique situation. According to a 2012 Pew Center study at least 1.8 million deceased individuals still appear in voter registration logs back then and thus get voter materials sent to them. This has not likely improved in the last 8 years.
It is likely that some inactive voters may have been caught up in this process. If you think that happened to you, or someone you know, all they need to do I re-register. They did not lose the right to vote they just have to put in a bit of effort to exercise it.
