The U.S. Supreme Court ruled 6–3 on April 29, 2026, in Louisiana v. Callais that Louisiana’s congressional map (SB8) was an unconstitutional racial gerrymander, concluding the Voting Rights Act did not require the state to draw an additional majority-Black district. Sen. Raphael Warnock, D-Ga., called the ruling “a massive and devastating blow,” warning it could accelerate redistricting fights across Southern states ahead of the 2026 midterm elections.
The court’s decision centered on when, if ever, a state may rely on compliance with Section 2 of the Voting Rights Act as a compelling reason to consider race in drawing congressional districts. The majority concluded Louisiana lacked that justification here because, in the court’s view, Section 2 did not require creation of a second majority-Black district, making SB8 an unconstitutional racial gerrymander.
The ruling immediately reverberated beyond Louisiana. Political and legal observers have said the decision could prompt new litigation and renewed redistricting efforts in multiple Southern states where maps have been challenged under the Voting Rights Act, potentially affecting the composition of several U.S. House districts before the 2026 elections.
Supporters of the decision argue it reinforces a more race-neutral approach to districting, while critics say it weakens one of the Voting Rights Act’s remaining tools for protecting minority voting power. Warnock told CBS News the court’s move could intensify what he described as a redistricting “arms race,” with communities of color at risk of losing influence in congressional representation.
