In a sweeping 6-3 decision issued today, the U.S. Supreme Court ruled that Louisiana’s congressional map with a second majority-Black district is an unconstitutional racial gerrymander. The ruling in Louisiana v. Callais (No. 24-109) delivers a major victory for Republicans by sharply curtailing the Voting Rights Act’s ability to compel the creation of predominantly Black or Hispanic districts - a development that could help the GOP protect and expand its House majority in the 2026 midterms and beyond.
