Blum is the force behind the Shelby County cases (killing a key part of the Voting Rights Act) and various attacks on affirmative action.
There was an earlier, unsuccessful challenge to the CVRA years ago, but this one seeks to take advantage of the Supreme Court’s racial gerrymandering line of cases.
The CVRA goes beyond what is required by Section 2 of the (federal) Voting Rights Act, and the claim is that any consideration of race for districting which goes beyond the Section 2 requirements is unconstitutional.
This is a case that could eventually make it to the U.S. Supreme Court, where its fate would be uncertain.
This is one to watch.
