Here in Maine, you can register to vote on the day of the election.
If I wasn’t already registered to vote, I could literally register to vote on Tuesday, November 2nd, and then cast a ballot minutes after I registered.
Montana too. You can even register to vote when you renew your driver's license or state ID.
An open invitation to vote fraud! No time to check out validity. I think the only way back to secure voting is by reserving the privilege to real property ownersonly, the way it originally was; no vote by mail, and no computer counting of ballots.
