Alabama was a unique situation in that it was the only state where you could easily draw another relatively compact majority black district. Even if SCOTUS ruled the other way, it wouldn't have mattered. Also keep in mind, this AL ruling is just about whether a stay should be granted, SCOTUS hasn't ruled on the merits yet but for the sake of argument if it did...
-The current Georgia map already passed, and the VRA lawsuit in Georgia was always a stretch, there's no clearcut way to draw another black majority district in GA the way there is in AL (I'm not even sure what the basis of a VRA lawsuit in GA is).
-In South Carolina it's similar, the way black people in SC are spread out makes it very hard to create a 2nd black opportunity district. SC is more of a partisan gerrymander than a racial gerrymander, so there's no real remedy under the VRA.
-As I said before about TN, there's no basis for a VRA lawsuit about Nashville even if the AL ruling was fully resolved in favor of the Dems. Davidson County is only 26% black and it's majority white; there's nowhere near enough minority voters there to argue that a VRA opportunity district is warranted. It's a partisan gerrymander, not a racial one.
-Louisiana is the closest thing there is to another Alabama situation but I the black population there isn't as compact as it is in Alabama, but more importantly it's a fifth circuit state, so it's never going to get a favorable lower court ruling the way the Alabama VRA suit did.
-In MO the decision not to crack Kansas City won't be impacted by this. They might still end up doing it, but it won't be VRA related. The reason they haven't cracked KC is because of selfish in bents who don't want to absorb blue areas into their district. Personally I don't understand why the state legislators give a about what in bents want, if I was a state legislator I would create as many districts for my party as possible and would tell selfish in bents to off and retire if going from a D +30 to a D +20 district is so traumatizing for them.
-I'm not familiar with the basis of the DOJ's VRA lawsuit in Texas, but I don't expect it to go anywhere.
A state court is never going to rule on the VRA so I'm not sure what you're talking about with the state court throwing a map out for not having VRA protected seats. The VRA is a federal law, any lawsuit bringing a cause of action under the VRA needs to be brought in federal court. If a plaintiff tried suing under the VRA in state court because it's a state where the state court is more liberal, the defendant would just have it removed to federal court as the proper venue.
