Supreme Court Strikes Down Louisiana Congressional Map
April 29, 2026 · 3:20 PM EDT
On Wednesday, the Supreme Court struck down Louisiana’s congressional map as an unconstitutional racial gerrymander, in a decision that could have far-reaching implications for a dozen or more Democratic-held districts across the South and around the country. The immediate effects of the decision on the 2026 midterms, however, are less clear. And as Democrats continue to perform strongly in competitive House districts across the country, it’s unlikely that this decision changes the underlying assessment that Democrats are favored to take back the House.
The Callais decision, authored by Justice Samuel Alito and joined by his five conservative colleagues, did not strike down Section 2 of the Voting Rights Act, as some had anticipated. But Alito altered its interpretation to such a degree that the law, which for decades has helped protect majority-Black and majority-Hispanic seats from being dismantled by aggressive gerrymanders, may in effect be toothless moving forward. In her dissent, Justice Elena Kagan wrote that the “decision renders Section 2 all but a dead letter.”
In practice, the Court’s decision likely comes too late to affect most states’ redistricting processes ahead of the 2026 midterm elections, even as the redistricting wars have raged on for the past 10 months. And because the Court did not explicitly overturn Section 2, it’s not obvious the extent to which mapmakers now have license to dismantle minority-opportunity districts with abandon.
First, the timing. The case centered on a majority-Black district Louisiana mapmakers drew ahead of the 2024 election following a previous Supreme Court decision. That district, now held by Democrat Cleo Fields, stretched from Shreveport to Baton Rouge and was challenged by “non-Black plaintiffs” in Callais.
That district will almost certainly cease to exist after this year. So may Alabama’s 2nd District, another minority-opportunity district drawn after the Court’s 2024 decision and held by Democrat Shomari Figures.
But it’s not clear if there is enough time ahead of this election for the Louisiana and Alabama legislatures to redraw its maps ahead of November. Both states’ filing deadlines have already passed, and their primaries — May 16 and May 19, respectively — are fast approaching. It’s not unheard of for states to hold statewide and congressional primaries on separate dates due to ongoing litigation, but inertia can be strong in redistricting cases, especially as absentee ballots have already been mailed out in both states and early in-person voting begins in Louisiana in two days.
It’s a similar story in other states across the South home to VRA-protected districts. Filing deadlines have passed in South Carolina, Georgia, Tennessee, and Mississippi. The primaries have already happened in Texas and North Carolina. The calendar may ultimately limit the ability of states to redraw their maps ahead of 2026 in response to this decision.
A more pressing case may be Florida’s ongoing effort to redraw its congressional map to help Republicans pick up as many as four additional seats. The ostensible rationale for approving Gov. Ron DeSantis’ proposed map rested in part on the assumption that the Court would strike down Section 2 of the VRA entirely, and also that Florida’s own anti-gerrymandering constitutional amendment is superseded by federal law. The Court’s decision to leave Section 2 in place, albeit essentially defanged, may not prevent the Florida legislature from approving the DeSantis map, but could create complications when the map is challenged in court.
Second, the scope. There is a long list of districts that could potentially be affected by this decision in the South alone: one seat each in both Louisiana and Alabama (in addition to the two seats mentioned above), one seat each in Mississippi and South Carolina, and another handful each across Georgia, Florida, and Texas.
A maximalist reaction to Callais could see Republicans aim to eviscerate all or most of those districts ahead of the 2028 elections, including seats held by longtime Democratic power players such as South Carolina’s Jim Clyburn and Mississippi’s Bennie Thompson. But those choices will come under individual legal scrutiny, in addition to the political challenges that accompany wholesale reconfigurations of congressional maps.
An early indication may come from Louisiana’s next steps. If the GOP-controlled legislature approves a map that dismantles not only Fields’ new district but also the longstanding majority-Black New Orleans-based district held by Democrat Troy Carter, it would be a sign that Republicans are opting for a maximalist approach. If Louisiana instead reverts to a pre-2024 status quo map that leaves Carter’s 2nd District unchanged, it would signal a more hesitant approach.
The medium- and long-term effects of this decision remain uncertain — especially if in 2028 Democrats respond in kind with more aggressive gerrymandering in the states under their control, such as Colorado, New York, Maryland, Oregon and elsewhere. But within the context of the 2026 elections, much is still the same. Democrats maintain an advantage on the generic ballot, the Republican president is deeply unpopular, and the vast majority of Congressional districts are largely set in place. With Democrats needing a net gain of just 3 seats to reclaim control, they remain favored to win the House this fall.
