To get an idea how long it has taken 12 years for Wisconsin to go back. After the "Red wave" in 2010. The GOP used their short term majority and a stupid Scott Walker to gerrymander themselves a safe Majority after the 2010 Census
It took until 2018 for Evers to narrowly win Election to Governor, and WI electing 3 Liberal supreme court Justices, replacing every conservative appointee.
Evers gave them a map that slightly Favors the GOP, which is better than a fair Court map
