The 6-3 majority opinion authored by Chief Justice Roberts states explicitly: 'race cannot be the predominant factor in drawing district lines.' Louisiana v. Callais pulls four decades of post-Gingles race-quota redistricting back to the 14th Amendment's equal protection baseline. Within an hour of the ruling, the Florida House passed a new congressional map 83-28; DeSantis is expected to sign. Cook Political Report's projection after the eighth state completes mid-decade redistricting: a net 11-14 GOP seat gain in the November 2026 House map.

The 6-3 Holding
Roberts, Thomas, Alito, Gorsuch, Kavanaugh, and Barrett form the majority; Sotomayor, Kagan, and Jackson dissent. The majority holds that Louisiana's 'two Black-majority districts' map — drawn under a lower-court order — itself made race the predominant factor, violating the Shaw v. Reno (1993) and Cooper v. Harris (2017) line. Section 2 of the VRA cannot be read to require states to 'affirmatively manufacture' racial-majority districts. Thomas's concurrence goes further: Section 2's 'results test' itself sits outside the 14th Amendment's textual boundary.

Florida Fires Within the Hour: 83-28 in the House, 21-17 in the Senate
Sixty minutes after the ruling, the Florida House passed DeSantis's new map 83-28; the Florida Senate cleared it 21-17 the same day — both votes party-line. The new map moves Florida's House delegation from 20R-8D to a projected 24R-4D, a net +4 GOP-leaning seats. Florida is the eighth state to complete mid-decade redistricting since Texas opened the cycle in 2025; the prior seven were Texas, Missouri, Indiana, Ohio, South Carolina, North Carolina, and Tennessee.

Section 2 of the VRA, Structurally Rewritten
Since the 1982 statutory amendment, Section 2 has been read as a 'results' test — any districting plan with a vote-dilution effect was actionable. Callais pulls Section 2 back to an 'intent' test: plaintiffs must prove subjective intent to dilute minority voting power. The practical effect on map drawing: the Allen v. Milligan (Alabama, 2024) line of lower-court orders that compel states to draw additional racial-majority districts is severed.

Updated Cook Report / 538 Estimate: Net +11 to +14 GOP House Seats in 2026
The pre-redistricting 2026 House baseline projected a net GOP loss of 3 to 5 seats (the traditional midterm penalty). After the eight-state redistricting cycle completes, Cook Political Report's April 30 post-close update revises the baseline to a net GOP gain of 11 seats, with an upside scenario of 14. Polymarket's overnight 'GOP holds House in 2026' implied probability moved from 53% to 68%.

The Real Voting-Rights Baseline Is the 14th Amendment, Not the 1965 Statute
Callais's doctrinal weight extends far beyond the 2026 midterms. It pulls the constitutional baseline of voting rights back from the tension between equal-protection-as-individual-right and quota-compensation toward the former. The same logic will extend into the next round of fights — state legislative maps, lower-court racial-classification challenges, and the residue of Section 5 preclearance. Roberts's closing line is direct: 'the Constitution protects persons, not racial groups.'
Six decades of race-quota redistricting was pulled back to the constitutional baseline in a single 6-3 opinion. Florida moved in under an hour. The other seven states were already in place. The 2026 House map war effectively ended this week.
