The Supreme Court appears ready to gut a key tool of the Voting Rights Act that's helped root out racial discrimination in voting for more than a half century. Such a change would boost Republican electoral prospects, particularly across the South. During 2 1/2 hours of arguments Wednesday, the court's six conservative justices seemed inclined to effectively strike down a Black majority congressional district in Louisiana because it relied too heavily on race. If that is the outcome, it would mark a fundamental change in the 1965 voting rights law that was the centerpiece legislation of the Civil Rights Movement. The court is expected to rule by early summer in 2026.
