The DNC is planning the long game. Mail in votes now so they can control things until this option is deleted.
Saw a HHN clip about voting. Had a lady taking the ballot and sleeve out of the envelope then putting the envelop in 1 stack and the sleeve+ballot in another. Assume the ballot was verified prior to this, but if there ever is a audit that turns up invalid voters, how do we know which ballot was in their envelope? This is rhetorical because this was addressed in the 2020 election fraud thread in great detail. Long story short, there is no way.
What if we went to a online instead? You have to either enter your states drivers license or state ID, followed by social, DOB,etc...A server can keep track of who you voted for and if it turns out you're not allowed to vote, then your vote can be purged. This would also keep track of duplicate votes since socials are used.
Now some may say, what if you have none, but a passport? I worked in a bank and the only people who brought a passport was cause they lost their ID's. It's too humbug to carry your passport compared to a plastic card. So they can vote in person.
What if you have no ID, then too bad. You cannot navigate life without an ID. But it would be the same as mail in ballots as there would be no signature to compare the signed envelope to.
Audits could be done much faster as random samples could be pulled to check voter status and stuff.
