So, I finished Texas' briefing and don't let anyone tell you this is a coup attempt or attempt to overturn election. It's not. There are serious constitutional issues. But, I doubt 5 justices will want to get involved and my gut prediction is that a majority of the court will 1/
2/deny Texas' request for relief, basically reasoning that the state legislatures could name the electors if they wanted to and by not doing so they are ratifying the results. In other words, Texas can't force MI, WI, PA, and GA state legislatures to remember we're a Republic.
3/ And frankly, our beef shouldn't be with the Supreme Court if it refuses to order the state legislatures to name the electors, it should be with the pantywaist chicken
state legislators who refuse to do so now. https://thefederalist.com/2020/11/19/state-legislatures-must-investigate-fraud-and-choose-electors-accordingly/

Now, the counter point would be that the Florida legislature in Bush v. Gore could have stepped in and done the same, so that is no answer to the constitutional violations. (My prediction still stands on outcome.)
