New York, Texas, Pennsylvania, Arkansas, Missouri, Indiana, Kentucky, West Virginia, Mississippi, South Carolina, Delaware, and Alabama all require an “appropriate” reason to use mail-in voting, iirc. There may be a few more that I’m not remembering, because that’s 12 and I think its about 15 states that need an “approved excuse” to vote by mail.

And in general I’d agree, mail in voting is just fine, but I’d make sure to get in in extra early - DeJoy will continue to fuck up USPS as best as possible I am sure, and states get to make their own decisions regarding deadlines. So any area that’s iffy to start with, yeah I can see in person being a much safer and more assured option.
