The Supreme Court handed down a seismic ruling Wednesday that fundamentally weakens the Voting Rights Act, dealing its strongest blow to local and state governments rather than federal halls of power. The decision in Louisiana v. Callais rewrote the test for applying Section 2, now allowing partisan gerrymandering to override protections for minority voters. Justice Samuel Alito wrote in the majority opinion that “because the Voting Rights Act did not require Louisiana to create an additional majority-minority district, no compelling interest justified the State's use of race.”
This ruling effectively neuters a key provision of the 1965 civil rights law that helped dismantle Jim Crow-era voting barriers. Section 2 cases were already notoriously difficult to win, requiring challengers to clear three procedural hurdles. The new opinion makes each of those hurdles significantly harder to overcome, opening the door for statehouses, county commissions, and school boards to ignore minority voting power as long as it serves other purposes like partisan advantage.
Most Voting Rights Act lawsuits target local entities that control school curriculums, policing, and infrastructure spending — not Washington. The impact could reshape voting across the South, with analysts estimating the ruling could boost the Republican House majority by an additional 19 seats when compared to 2024 maps. As Michael Li of the Brennan Center noted, the decision may trigger widespread map redrawing as officials now feel “free to do what we want.”
The ruling also directly aids Florida Gov. Ron DeSantis' push to create four new Republican congressional seats, despite a state constitutional amendment barring intentional partisan gerrymandering. Democrats and liberal groups plan to sue once DeSantis signs the maps. A key question remains whether Florida's entire redistricting reform will be struck from the books, as DeSantis argues the amendment was sold as a package that bans both racial and partisan gerrymandering.
The court did not fully strike down Section 2, and Florida's law contains a separate clause forbidding maps designed to “favor or disfavor a political party or an incumbent.” However, the ruling's practical effect is immediate: local and state bodies now have broad latitude to draw maps that dilute minority voting power, provided they cite partisan or incumbent protection as justification. Civil rights groups warn this could usher in a new wave of discriminatory redistricting ahead of the 2028 census cycle.
