There remains a problem with this strategy. Mail in ballots will not be counted until after polling day. Even if your mailed in ballot has been received (and the fact is noted by election supervisors - that will be a cluster fuck of gargantuan proportions), and you are told you don’t need to/cannot vote in person, there’s no guarantee that your ballot will be counted.
Vote in person. Get a receipt. And hold fast to your right to vote, whatever crap they pull to frustrate the process on polling day.
