The Supreme Court dealt a major blow to voting rights on Wednesday, significantly narrowing a key provision of the landmark 1965 law. In a 6-3 decision in Louisiana v. Callais, the court rewrote the test for Section 2, which prohibited racially discriminatory gerrymandering, effectively neutering its power. Civil rights groups suffered a loss that could reshape voting across the South, potentially adding 19 Republican seats to the House compared to 2024 maps.

The ruling does not erase Section 2 but makes it far harder to enforce. The court held that protections for minority voters cannot infringe on state lawmakers' ability to draw partisan gerrymanders. Justice Samuel Alito wrote that because the Voting Rights Act did not require Louisiana to create an additional majority-minority district, the state's map was an unconstitutional racial gerrymander. This rewrite hands state and local bodies broad discretion to ignore minority voters as long as some other purpose, like partisan advantage, is served.

Most Voting Rights Act lawsuits target local and state governments—entities that control schools, policing, and infrastructure. Challengers already faced three procedural hurdles to prove a violation; the new decision makes each one even steeper. As Michael Li of the Brennan Center noted, the impact could cascade: city councils, county commissions, and school boards may see maps redrawn without minority safeguards.

The broader implications are stark. The decision effectively gives carte blanche for partisan gerrymandering at the local level, where most Americans encounter government directly. Experts predict a surge in legal challenges and map redraws across the South and beyond.

Critics argue the ruling misreads Section 2's intent, which was designed to dismantle Jim Crow-era barriers. They warn that without robust judicial review, minority representation in state and local government could shrink dramatically.
