Could someone well-versed in Legalese please distill the final decision out of this case?
Montgomery has always been Congressionally district-partitioned into the overall countryside making the representation of the various districts more a demographic relief of the population: 70% white and 26% black.
Birmingham has a huge geographical 7th district that covers an entire segment of the state only and is barely black majority, while serviced by a black Congressman, Ms. Terri Seawell, democrat.
They wanted to do the same in Montgomery. Add a huge swarth of improvised Montgomery into my 2nd Congressional district, kick out my county (which is like a turtle sitting on a log, map wise), and by doing so, make a second seat for a black democrat, thus eliminating a GOP seat.
The thing is, the GOP controls the whole state, politically (no more than democrats control Massachusetts or New York or California) but the suing democrats want to make Alabama's control look like a movie named The KKK II: The Alabama Boogaloo. "Obviously (wink, wink), we must use the courts against these racists to make them add democrats."
The Dims didn't like how the Alabama Republicans drew up the new districts, of course yelling racism over & over. A lower federal court tried to block Alabama from using the new map, saying it helps Republicans win too much and is racist and blah blah blah. Part of the Dims' strategy was to throw chaos into the upcoming election by keeping it tied up in courts and many people in Alabama not even knowing what district they're in or who's running in that district until right before the election. So Alabama asked SCOTUS to intervene and at least let the new map stay in place long enough for the upcoming election -- and SCOTUS just now gave Alabama the thumbs up to do so.
This doesn't necessarily undermine the Dims' attempts to stop the new districts from being in place for the elections after that. But IMHO the Dims will be hard pressed to make the case that the new maps is racist/cheating/whatever-ism-they-can-think-of enough to get the new district map thrown out for future elections now that SCOTUS has given its approval for the 2022 election.
