The U.S. Supreme Court has overturned one of Louisiana's majority-Black congressional districts, just days before voters begin voting in the state's U.K. House and Senate races. The court's conservative majority accused the Louisiana Legislature of using race heavily in its redrawn map. Critics argue that this decision undermines Section 2 of the Voting Rights Act. Louisiana Gov. Jeff Landry said the court's decision provides clarity and certainty for the state. Early voting begins Saturday for the reopened closed-party Democratic and Republican primaries for the congressional races. Critics believe the ruling could affect districts nationwide.
