SCOTUS Redistricting Ruling Prompts Map Redraws in South

The Supreme Court’s decision in Louisiana v. Callais has set states across the South on a path to redraw electoral districts, raising questions about how many majority-Black districts will survive the next round of mapmaking ahead of the 2026 midterms and beyond.

In the ruling, the Court held that Louisiana’s congressional map, which created a second majority-Black district, violated the Equal Protection Clause because race predominated in its design and the state did not demonstrate that the configuration was narrowly tailored to comply with Section 2 of the Voting Rights Act. The decision did not alter Section 2’s results-based test into an intent requirement.

Republican-led states have already begun adjusting maps. Alabama moved to redraw state Senate districts to eliminate two majority-Black districts near Montgomery. Mississippi indicated plans to revise state supreme court districts before the 2027 election. Local government bodies, including county boards and school boards, face similar pressure because Section 2 also covers those lines.

Advocates for minority voters argue the ruling will reduce competitive seats and limit opportunities for Black candidates in state legislatures and local offices. A manager at the Legal Defense Fund cited DeSoto County, Mississippi, where Black residents comprise one-third of the population yet hold none of 25 elected positions on key boards. Officials in several states have suspended or accelerated redistricting processes to test the new boundaries.

Democratic groups view the ruling as increasing the stakes for state legislative races, where breaking Republican supermajorities could restore leverage over future maps. Map-drawers, speaking anonymously, noted that states already holding supermajorities may avoid further changes to Black Democratic districts to limit legal exposure under the Fourteenth Amendment.

The immediate effects will appear first in local elections and state legislative contests rather than congressional races, as those maps are redrawn under the same Section 2 framework.
