Yes, every election should require re-registration. They should send out a mailing to every previous voter some months in advance asking for them to provide current proof of citizenship and re-register, or come to the polling place with ID.
You don't need re-registration, registration is done automatically and you are set to vote in a poll station nearby your register address with an official ID.
If you are not citizenship, you don't have an official ID
If your citizenship has expire for one reason or another, you are illegal and thus you don't have a register address, so you don't get a vote registration.
If you change your home address, again, your registration is done automatically for you and you don't need to do anything.
If you can't vote for whatever reason on that day (military, out on a business trip, post-surgery in the hospital...) then you register for mail in voting. Your automatic register is thus automatically deleted and you can only vote by mail in your town city hall with valid official ID. And you need to do it like at least one week before the election so your actual ballot is literally put inside the box that collect the votes before anybody else drop their in person.
They should be making voters register every election, issuing one-time-use Voter IDs each election, and requiring voters to either bring that ID with them to the polling place or send it in with their absentee ballot. The Voter ID gets stamped or hole-punched when it is used. And stamp people's hands or fingers so that they can't pull any shenanigans claiming that their Voter ID got lost or damaged.

These are standard practice through out Europe.
I'm happy with anything as long as there is ID! That's the first thing that needs a change.
