The Supreme Court ruled 6-3 in Louisiana v. Callais on 29 April 2026 that Section 2 of the Voting Rights Act does not require states to draw majority-minority congressional districts, overturning the 1986 Thornburg v. Gingles doctrine.

Which states are redrawing congressional maps after the Voting Rights Act ruling?

Tennessee, South Carolina, Mississippi, and Alabama were the first to move within 24 hours of Callais. Louisiana must redraw its own map under the immediate-effect order. Florida, Georgia, and other Republican-controlled states are also expected to act.Source: CFR, Brennan Center

Background

The Supreme Court's 6-3 ruling in Louisiana v. Callais on 29 April 2026 gutted Section 2 of the Voting Rights Act, holding that states are not required to draw majority-minority congressional districts. A judgment forthwith on 5 May forced immediate effect, bypassing the standard 32-day remand window and freeing every Republican-controlled legislature to redraw maps before November 2026 .

Section 2, enacted in the Voting Rights Act of 1965, prohibits any voting practice that denies or abridges the right to vote on account of race. From the 1986 Thornburg v. Gingles ruling Onward, courts interpreted it as requiring states with sufficient minority populations to draw districts where those communities could elect their preferred candidates. That doctrine sustained majority-Black or majority-Hispanic seats across the South and Southwest for four decades. Callais overturns that reading entirely .

The practical effect for the 2026 midterms is substantial: pending redistricting litigation in Louisiana, Georgia, Alabama, and South Carolina can now be dismissed, while Tennessee, Mississippi, and other Republican-led states have already moved to redraw. Analysts estimate the ruling could yield a net gain of 8-12 Republican House seats before voting begins.

Section 2 was previously the subject of a separate Lowdown entity (VRA Section 2, slug vra-section-2) which has been merged into this record. That entity's background documented the pre-ruling landscape: SCOTUS oral arguments signalling a narrowing, DeSantis timing Florida's redistricting to await the outcome, and the Brnovich v. DNC (2021) precedent that foreshadowed Callais. The merged content is now consolidated here. The ruling outcome is reflected in the identity section above .
