Voter rolls should be cleared every ten years, and people need to re-register to vote and not by mail.
Here in CT we have a registered voter at our address—who moved more than twenty five years ago—I have no idea where they are—it is entirely possible they are dead.
They keep getting called for jury duty over the years—and I have written nasty notes in response.
So far they are still on the voter list.
