> The notices are generated after the state compares the list of people who submitted a change of address form to the U.S. Postal Service with the state’s overall list of registered voters.
> Voters who receive them are asked to fill out the form and return them to their local county elections office. The notice says a voter will be declared “inactive” if they don’t respond within 30 days. Several advocacy groups including the ACLU of Georgia, however, say not all voters should face that consequence.

> Now, in Wisconsin, it's a whole different case. It's the state that wants to wait until after the 2020 elections to remove some 234,000 voters who appear to have moved. They want to wait because they've run into problems in the past using Division of Motor Vehicle change of address records to clean up their lists.
Removing people from voter rolls should require making active efforts to determine if there is a change in voter status. For example, are they still filing taxes at the same address? The most common cause of stale voter roll information is people moving, and the voter database not reflecting it, but there are already several government databases that will reflect whether or not someone has moved. Purging voters simply because of nonresponse and non-voting should be insufficient burden of proof--and yet states have tried to do that in the past.
It's actually quite frustrating how many different government agencies I have to inform of my move [1], especially because there's very little indication of who will and who won't be told of it.
[1] The title registration of my car and my driver's license not using the same database is particularly frustrating because it was the same damn agency.
