The Court concludes that the following Challenged Districts constitute unconstitutional partisan gerrymanders, in violation of the First and Fourteenth Amendments, because they dilute the votes of Democratic voters: Congressional Districts 1, 4, 5, 7, 8, 9, 10, 11, and 12; Senate Districts 8, 11, 12, 14, 18, 27, and 36; and House Districts 24, 32, 51, 55, 60, 63, 75, 83, 91, 94, and 95.
That's quite a lot of congressional districts.
I do agree about the legislature though, the Michigan Democrats have won the statewide house and senate votes multiple times this decade but never once got a majority. Sometimes those wins were by 7-8%.
