Yeah, state GOPs are figuring out that if they just ignore their state supreme courts, the two outcomes are: the opposition appeals to the federal Supreme Court with the same, or worse, outcome, or... nothing.
The states that can are at least addressing gerrymandering through ballot initiatives and state constitutional amendments. Ohio is on track for this. Ohioans shot down the attempts at undermining their ballot initiative process, and are now attempting to get a citizen redistricting commission on the 2024 ballot. We'll see how it goes.
Needs to be enforced by an independent party, and as we saw in Ohio, the GOP will just go, "Nah, we think we'll keep it."
