New York Is Ordered by Appeals Court to Redraw House Map (possible +6 Shift in NY alone)
There are numerous states with map issues due to the GOP clearly gerrymandering and weakening democrat strongholds and minority voters. A new SCOTUS ruling that affected Alabama will almost certainly affect several states in the south adding a new minority district to each and taking away one from the GOP. Could be as many as 5 new seats from Tx, GA, SC, LA and Mississippi.
Florida is being litigated currently for breaking up its former minority district. Again this is almost certainly going to come back plus another one due to the SCOTUS ruling.
WI is likely to be fixed due to their new SCOTUS. Its essentially a 50/50 state but due to the extreme gerrymandering, nearly 70% of seats are GOP controlled. Easy to see 2-3 seats back in Dem control or at least vastly more competitive.
Some of this may not shake out before 2024 but most of it should.
