Looking at Wisconsin statewide races in the Trump era:
2018 WISC: D+10
2018 Gov: D+1
2018 Senate: D+11
2019 WISC: R+0
2020 WISC: D+11
2020 Pres: D+1
2022 Gov: D+4
2022 Senate: R+1
2023 WISC: D+11
If representation actually means fair representation again at the WISC, it looks easy to argue that a 6-2 congressional map fails to represent the electorate, and thus should be struck down.
For instance, I live in NYC; no matter what I am going to be in an extreme lopsided D district where my vote is "wasted", but that isn't inherently unfair, at least compared to the alternative of Bacon-Stripping a Brooklyn Assembly District out to Staten Island or Long Island.
Bad analogy. There is a difference in kind: the dominant party is already in power in NYC; your vote would only pad their margin and bring little change to policies enacted. This is worlds apart from a situation where the NY leg would be controlled by the GOP because your vote was wasted.
Firstly in most of those D+10 races, the breakdown was 4-4. Imo, the main issue with the current map is there should be a swingy R-leaning seat that keeps the Fox Valley together that would allow a 5D-3R outcome in Baldwin or Protacewitz style wins. WI only produces a 6-2 outcome when Republicans are viable statewide.
Also it doesn't matter if there's a dominant party or not. Intentionally trying to unpack specific communities over others is wrong; reverse-gerrymandering is still wrong, even if it achieves an outcome that may be fair when it comes to partisanship. Any map that violates neutral principles to achieve *any* partisan target is not good.
With that being said, if there are 2 equally good maps of Wisconsin, the only difference being one has more equitable partisanship, I'd choose the one with more equitable partisanship.
Under your logic we should try and draw that absurd Trump Congressional District in Massachusetts, or bacop-strip the Nevada General Assembly out to rural Nevada in the name of partisan fairness for the minority party.
