It’s a fair map, and it’s helping Democrats because it’s not tilted to help the GOP. Needless to say, Republicans are angry. The redistricting map was drawn with the help of Stanford University law professor Nathaniel Persily, who has helped with the development of other maps used to determine House of Representatives districts elsewhere in the country, according to Politico.
