I hadn't heard of any of that so I went to read some. The Demonrats are hilarious. According to the article, they accused the Republicans of "racial gerrymandering".
Also, according to the article, the map modernizes the state’s redistricting process by removing “racial data from the mapmaking process entirely.”
So, if I'm understanding the Demonrats, it's "racial" because the Repubs took race out of the equation?
