The Texas Supreme Court has ruled against those who would like to cast mail-in ballots in order to avoid having to go to crowded, public polling places to exercise their right to vote.

And it did so remotely. https://twitter.com/texastribune/status/1265776849382191104

Although it disagreed somewhat as to why, the Court unanimously agreed that fear of contracting the coronavirus is not, at least in general, a "disability" justifying a request for a mail-in ballot.

There's still the federal lawsuit, but I'd be more than a little surprised if the Fifth Circuit were to hold that Texas law, as construed by the Texas Supreme Court in this ruling, violates the federal Constitution.
