I expect the state’s lawyers are spending the weekend drafting an emergency motion to SCOTUS to stay this ruling for the March election, given that absentee ballots are already out. I would not at all be surprised to see a stay even if, as seems fairly likely, this ruling is ultimately affirmed by the Supreme Court for future elections.
And of course, North Carolina could potentially moot this case by drawing new districts that are political, but not arguably racial, gerrymanders.
