WASHINGTON (AP) — The Supreme Court has weakened a landmark Civil Rights-era law that has increased minority representation in Congress and elsewhere. In a 6-3 ruling, the court’s conservative majority on Wednesday struck down a majority Black congressional district in Louisiana. The decision opens the door for more redistricting across the country that could aid Republican efforts to control the House. The effect of the ruling may be felt more strongly in 2028 because most filing deadlines for this year’s congressional races have passed. It’s unclear now how much is left of Section 2 of the Voting Rights Act of 1965. That law is the main way to challenge racially discriminatory election practices.
