All states will, that's not the problem. The problem is that after the ballots are filled out and mailed back, the USPS will run the bar codes from each one against their own "APPROVED" list, and if a bar code isn't on the list, they will reject the ENTIRE BATCH, which could be as many as 10,000 ballots.
Nobody has seen this Approved List, nobody knows who made the list, what data the lists were compiled from, who is in charge of the list, who is in charge of this program, what's going to happen to the rejected ballots - anything.
So states can send out their ballots, people can fill them out and send them back, but you will never be sure if your vote ever got counted. Unless MAGA does well this election, then you'll know.
Giving the enemy righteous justification to attack us, and then acting shocked, is core American geopolitics.
