This has been a disaster this cycle for the GOP
On the Margin
Midterms have never been determined by redistricting
It hasn't determined which party had a majority, but there is a substantial difference between an R+15-20 majority and an R+30 majority.
This could make it far easier for Democrats to take back the House in 2024.
NC gop will certainly do a mid decade redraw for 2023 unless the court doesn't flip.
How safe would the R majorities in the state legislature be, though? They literally read efficiency gap into the state constitution!
Also, worth noting that mid-decade redraws for state legislative maps aren't allowed in NC, so whatever legislative maps result from this process are for the whole decade.
I suppose they could go to SCOTUS with the "independent state legislature" argument since congressional maps are for federal elections. A favorable ruling would give them back control of NC, OH, and AZ and also throw out the rules in FL, but it would also give Dems a chance to draw 49 67% Biden districts in CA and the NY courts would lose their ability to block the gerrymander there. It would also result in immediate Dem control of WA and CO redistricting and a probable mid-decade Dem gerrymander in VA.
Pretty safe. The Democrats' real chance to win a State Senate majority was in 2020, when despite losing 5 seats in the State House they gained one in the Senate, and probably would have won a majority with a 1% popular vote lead, almost definitely with a 2% one. The issue for Democrats is they have a bit of an exaggerated view of what gerrymandering does in NC as they view NC like Wisconsin as being about 5% more Democratic than it actually is.
Democrats kind of view NC as a D+1 state which due to gerrymandering behaves like a R+7 one. In reality, it is an R+3 state which because of gerrymandering behaves like an R+7 one. Democrats might win legislative majorities on entirely non-partisan maps in a landslide year like 2018, but even then you would be talking about maybe one to two seat margins. Notice the NCSC Ds went further than last time. They realized that neutral/nonpartisan maps will probably never produce D majorities so demanded affirmative gerrymanders in favor of Democrats with the proportionality stuff.
In short, gerrymandering is largely why the GOP generically would have 32-18 and 73-47 majorities rather than 28-22 and 66-54 ones most years. Democrats range from 45-50% of statewide vote and GOP from 48-54%. As was seen with 2020 statewide races, even a landslide reelection for Cooper wasn't that wide.
