If someone's issued a death certificate, if a building is rezoned as commercial, or condemned, change of addresses, felony convictions, etc etc. If the state had a streamlined updated system, the voter rolls could update themselves, thus preventing the cursed "voter fraud" as well as freeing up actual people from doing the work a computer could do and do better. Not to mention preventing actual voters from being kicked off the roles in these sweeps many states seem fond of.
I tend to think that in matters such as this; you have to get away from the automation process too much. How many John Smiths die each day? I'm not sure. I bet it's a lot. Then there are overlapping jurisdictions between state, federal, local agencies. Who says they are all on the same page as to the right John Smith? I heard somewhere that over the next 10 years, 18,000 Americans will be turning 65 each day. I don't know how accurate that is but really...this is going to get worse.
When I moved into this Condo, my phone was not switched due to some reason. So I got a new number. Some guy/gal named Tillis had the number first. They likely have this address too. If a Tillis turns up dead; they may bump me off the voting rolls based on my address. Maybe not.
I think the point is that we want more government than we're willing to pay for and we want a government to be able to take swift action in some cases while being totally ignorant of our personal lives in others.
Until we determine that it is worth paying a few extra employees to tend to the voter rolls, tend to the unpaid parking tickets, unpaid taxes, malfeasance, etc...we're going to have instances like this.
