Even if they actually address the ballot to every registered voter, how many of those are going to be dead, no longer in the state, or otherwise ineligible to vote?
If you live in the average apartment building, when someone moves out without a forwarding address, their mail just piles up in the lobby under the mailboxes - ripe for anyone to go around and harvest, and use in whatever way they want.
In my state, to vote absentee, you have to request an absentee ballot, explaining your reason/need, and they send it to you. It’s not just a matter of mailing out ballots to everyone, as mail-in voting would be.
Someone else here noted that pre-paid mail, as this would probably be, isn’t tracked by the post office. How do you know if your ballot even made it to its destination, or when? Who is going to keep a record, and how, if you want to track whether your vote was registered?
There are lots of reasons why mail-in voting is dangerous - fraud, long delays in counting and knowing results; and lots of legal disputes will arise.
I have a friend who runs a recycling center. He’s a huge Trump supporter. If I asked him to salvage all the discarded ballots from the waste stream; and told him they would be filled out for Trump, I suspect he might agree.
I wouldn’t actually make an ask for this but there are people who would. And while the benefit might go to Trump this time, it could go to AOC in the future. I’ve read that candidates spend about $100. per voter. That begs the question of how much is that loose ballot worth? In a metropolitan area, one could easily snag 500 to 1,000 unopened ballots per day from the waste stream.
Mail-In voting is a horrific idea that is in no manner comparable to absentee voting. People using the terms interchangeably are either terminally stupid or cynically disingenuous.
Danger, Danger, Will Robinson!
