The technology is available. I can’t see it flying if the ID isn’t okay.
I have no idea what the legal questions would involve, however if the state of Texas, issues the identification, they could do issue it at a polling place, just as well as a state office, then allow whomever to vote, but issue that vote an (*) pending approval by the state.
I say call their bluff, and lets see how many of these so call discrimination cases actually qualify to vote.
