I'm hearing conflicting reports that SCOTUS has decided to not rule on this. Do we know anything definitively at this point?
Well, Sekulow's team discussed Alito and Thomas' previous opinions that the Supreme Court has to take a case where one state is suing another (for anything) because the Supreme Court is their ONLY court.
They discussed docketing + request for a response from the defendants = acceptance of the case.
They went on to a pretty lengthy discussion of the possible remedies with all agreeing the SC will not decide the outcome of the election. They would find for Texas (yea or nay). Texas essentially says the four states conducted an illegal election by not following the constitution. If it's "nay" for Texas, it's over. It means the four defendant states conducted legal elections in accordance with the Constitution. (Remember, this suit is not about fraud)
If it's "yea" for Texas -- it means the court agrees that those four defendant state elections were illegal and this disenfranchised voters in those four states and all others. The court would most likely say to those legislatures: Fix it. Choose your electors with the understanding if the legislatures cannot and no one reaches 270 electoral votes this election goes to the House of Representatives for one vote one state.
The discussion was pretty good .... it's about an hour. It's also broadcast over radio so it's not something someone has to sit and watch.
