What would you propose in lieu of some form of identification?
Is there a way to establish that a person walking up is: - Registered to vote - Resides in the precinct - Has not had their right to vote revoked (i.e., felony conviction, prior fraud conviction, etc) - HAS NOT VOTED ALREADY (by mail, in another precinct, etc)
And those who cannot or will not present identification are still allowed to vote a provisional ballot. The canvassing board then establishes the eligibility of this voter (not the polling station) and counts the vote if they are eligible.
So there is a way that someone with no ID can vote legally. It's just a bit more time consuming than the more automated systems.
