Evidently, the Sixth U.S. Circuit Court of Appeals refused to set aside this law. Since the Supreme Court has refused to review it, that makes it the law of the land within the Sixth Circuit, which consists of Michigan, Ohio, Kentucky, and Tennessee.
This law will remain in effect until such time as a similar case is decided differently in some other Circuit, which would create a "Circuit split" and the Supreme Court agrees to review that case and decides differently.
That is unlikely to occur any time soon at all. I can imagine, if Trump loses, that the Demoncrats might pack the Supreme Court, initiate a similar case, and fast-track it to THEIR Supreme Court. Not at all likely to happen.
I would expect that every red state will have such a law on their books in record time.
Thanks. Good info.
