I am not in the habit of saying never, so maybe you are the exception, but this just isn't true in general.

RI sent out applications for mail voting to everyone. Applications. Like you fill it out and return it (postage paid) and you then get a mail ballot.

I saw many many posts like yours on various social media about getting ballots in the mail when every time they were applications, not ballots.

If you want to say that's a huge waste of money just to try and get voter engagement, that's fine but reasonable people could disagree.

I also had a few people show up at the polls who had requested mail ballots and got really fucking pissed when I told them they had to do a provisional ballot so that it could be reconciled against their mail ballot so that it wouldn't be counted twice - but that it would count if they hadn't sent in their mail ballot. Yeah, turns out every one had already voted by mail.

The system isn't perfect but it works much much better than people think in terms of voter fraud.
