Who Drew the Maps — Redistricting as Power Design
The Supreme Court didn’t just rule on Louisiana. It rewrote the rules of the game.
On April 29, 2026, the Supreme Court issued its 6-3 ruling in Louisiana v. Callais and, in the dissent’s language, rendered Section 2 of the Voting Rights Act “all but a dead letter.” Justice Samuel Alito’s majority opinion struck down Louisiana’s remedial congressional map — the one drawn specifically to create a second majority-Black district after years of litigation — on the grounds that it constituted an unconstitutional racial gerrymander. Louisiana reverted to its original map: one majority-Black district out of six, the same configuration a federal court had already found diluted Black voting power.
The ruling’s immediate effects were visible within hours. Florida passed new congressional maps the same day the decision was released. Tennessee followed days later. Louisiana and Alabama moved their primaries to accommodate redistricting. More than a quarter of all congressional seats have already been redrawn mid-decade as part of a gerrymander cascade that began when Donald Trump pressured Texas to redraw its maps in the summer of 2025 — explicitly to add five Republican seats in Congress. What Callais did was remove the primary legal mechanism plaintiffs had used to challenge those maps. A state can now argue that its map was drawn for partisan advantage rather than racial discrimination, and courts will largely accept that framing even when the practical effect is to eliminate majority-minority districts.
Nick Stephanopoulos, an election law professor at Harvard Law School, described the current moment as “a totally different world” and “a pretty distinct break with the past.” The break is specific: partisan gerrymandering, which the Supreme Court declared unchallengeable in federal courts in 2019, can now function as a legal shield against racial discrimination claims. Draw a map that diminishes Black or Latino representation, argue that the goal was partisan rather than racial, and the Callais framework makes it extremely difficult for plaintiffs to prevail — even when the outcome is racially discriminatory in practice.
NPR reported on June 5 that the Public Interest Legal Foundation filed a federal lawsuit within days of Callais challenging the Illinois Voting Rights Act of 2011, arguing that requiring the use of race in state redistricting is itself unconstitutional. Similar lawsuits are expected in other states with state-level voting rights protections. The implications extend beyond the maps being drawn now: they reach the legal infrastructure that allowed minority communities to challenge discriminatory maps at all. Callais is not only a redistricting ruling. It is an instruction manual for how to legally diminish minority political representation while insulating the process from judicial review.
Harvard Kennedy School professor Alex Keyssar told NPR that voter confidence depends on a sense of fairness — that votes translate proportionally into representation. Extreme gerrymandering works against that sense directly. What Callais produced is a system in which the rules of map-drawing now formally favor the party willing to gerrymander most aggressively, minority representation can be reduced as a byproduct of partisan competition without legal consequence, and the enforcement mechanism that existed since 1965 to prevent exactly this outcome has been functionally dismantled. The 2026 midterms will be the first national election conducted under those conditions. The maps being drawn right now are the maps those elections will be run on.
