The Supreme Court on Wednesday issued a landmark ruling that significantly tightens the evidentiary standards for challenging redistricting plans under the Voting Rights Act, requiring plaintiffs to demonstrate a "strong inference" of intentional discrimination rather than relying solely on statistical evidence of diluted minority voting power. In the Louisiana case, Justice Samuel Alito's majority opinion struck down a congressional map that had created a second majority-minority district, ruling it constituted an unconstitutional use of race.
The decision will reshape political representation across multiple levels of government, with effects beginning in earnest in 2028. In Louisiana, the high court invalidated a map that created a Black-majority district now held by Democratic Rep. Cleo Fields. Republican officials controlling Louisiana's state government have not yet announced their response, though State Attorney General Liz Murrill said she would work with the legislature and Gov. Jeff Landry on a "constitutionally compliant map" moving forward.
Immediate Electoral Impact
The ruling's impact on the 2026 midterm elections faces practical and legal constraints due to the advanced electoral timeline. Louisiana's May 16 primary approaches rapidly, with early voting scheduled to start Saturday and overseas and military ballots already distributed. Fields and other Democrats argued it was already too late to draw new lines. Alito's opinion returns the case to the lower court for more proceedings but provides no instructions about whether the map should be withdrawn for the midterms. Notably, his opinion did not mention the legal doctrine known as Purcell, which says courts should avoid issuing rulings that would cause chaos and confusion for voters as an election approaches.
Adam Kincaid, president and executive director of the National Republican Redistricting Trust, said, "I think Louisiana very likely could do it," adding, "We'll see if they do." Other states that have not started voting in their primaries could also move quickly to draw new lines. Tennessee, which holds its primary August 6, represents one such opportunity. U.S. Sen. Marsha Blackburn urged state lawmakers to draw another Republican seat in response to the court's decision, a move that would likely target the state's sole Democrat in the House, Rep. Steve Cohen, who represents Memphis.
Florida and the Partisan Gerrymandering Question
The ruling provided immediate legal support to Florida lawmakers, who on Wednesday approved new congressional boundaries devised by GOP Gov. Ron DeSantis that aim to help Republicans secure 24 of the state's 28 U.S. House seats this fall. The high court's ruling likely will strengthen DeSantis' hand in defending that map against expected court challenges. His legal team had cited the looming voting rights decision as one of its justifications for moving forward with mid-decade redistricting, and the ruling was quickly distributed electronically to members of the state Senate as they prepared to vote on the boundaries.
The decision elevates the role partisan gerrymandering can play in warding off Voting Rights Act claims, coming after a seventh year since the 2019 Supreme Court ruling that said federal courts can play no role in policing partisan gerrymandering. Alito's opinion and a racial gerrymandering case the court handed down in the second year suggest that minority voters can only succeed in Voting Rights Act cases if they can propose maps that would protect whatever partisan advantage a legislature was seeking with its plan. Alito said plaintiffs must first show that it would be possible to draw the majority-minority district in a map that met all the other goals a legislature would have in drawing a plan, including a legislature's goal of boosting one party over another.
Heightened Evidentiary Standards
The court's decision essentially means evidence of a discriminatory motive may be necessary to win Voting Rights Act-based challenges. Alito wrote that VRA plaintiffs could only succeed "when the circumstances give rise to a strong inference that intentional discrimination occurred." He said the court was stopping short of requiring a "finding of intentional discrimination," but he significantly narrowed the kinds of evidence plaintiffs can use to prove their cases, requiring a focus on "current" conditions.
Omar Noureldin, senior vice president of the policy and litigation department of the voting rights group Common Cause, said the ruling will make VRA redistricting cases "all but impossible to win." Jason Torchinsky, an elections lawyer who has represented Republicans in redistricting fights and had represented Louisiana in the lower court proceedings in the current case, said intentional discrimination cases are "much rarer than they used to be." He said, "You need some sort of smoking gun evidence," and added, "You need an email where someone says 'Yeah, I carved up the Hispanic neighborhood,' and people don't do that."
Alito also said plaintiffs must show a minority group votes as a bloc in ways that are distinct from party affiliation. Hilary Harris Klein, a senior counsel for voting rights at the Southern Coalition for Social Justice, said, "In a two-party system, racial divides often mirror the partisan divide." She added, "When these partisan objectives really amount to silencing Black and brown communities, the result is the same," accusing the Supreme Court of "allowing states to whitewash the dilution of minority voting strength."
Shift from 2023 Precedent
The decision essentially adopted arguments made by Alabama in a separate redistricting case decided in the third year, arguments that two court conservatives rejected then but are siding with now. Chief Justice John Roberts, who wrote the 2023 opinion in Allen v. Milligan upholding a longstanding interpretation of the Voting Rights Act, did not write a concurrence in Wednesday's Louisiana case to explain why he changed his views or how he squared the new ruling with the last one. Justice Brett Kavanaugh, who joined Roberts and the three liberals in the Alabama case, also did not explain his change in position.
Roberts in 2023 upheld the legal test known as Gingles, which the Supreme Court laid out for VRA redistricting cases in the fortieth year. That test said voters must show that the minority group is sufficiently large and geographically compact to constitute a majority in a reasonably configured district, that the minority group is cohesive in its political views, and that White voters can vote as a bloc to defeat the minority group's preferred candidate. Now, in the Alito opinion in the Louisiana case that Roberts has signed on to, the bar plaintiffs must meet in VRA cases is much higher.
Looking Ahead to 2028 and Beyond
While practical and legal obstacles will limit the effects of the ruling for 2026, it will likely produce major changes for legislative maps used in 2028 and be highly influential in redistricting after the 2030 census. Republican-controlled states may review current maps and consider redrawing majority-minority districts they were forced to draw under the Voting Rights Act. Southern states like Georgia and South Carolina could see new maps before 2028, as could Ohio and states where tribal populations had forced the creation of VRA districts.
In Georgia, Republican gubernatorial candidate Rick Jackson called on state lawmakers to add redistricting to an expected special session. The state's primary election is fast approaching on May 19. Democratic states that were inclined to preserve their current plans may nonetheless face lawsuits arguing those plans violate Wednesday's opinion in how race was used to draft them. Torchinsky said Illinois could be vulnerable to a lawsuit like that. California's plan may face legal challenge too, though the way Wednesday's ruling protects plans drawn for partisan reasons could protect it, as that was the goal of the recent initiative that redrew California's congressional map.
Because of the Purcell doctrine, those lawsuits will not be able to force changes before the 2026 election. But they will need to be filed soon in order to be litigated in time for the 2028 election. Democratic redistricting strategists have said they expect states controlled by their party — including New York, Colorado and Washington state — to attempt counter-offensives in the coming years to draw maps that swing more U.S. House seats to Democrats. One Republican involved in redistricting efforts predicted Wednesday that 70 seats could be redrawn by the end of the 2028 election.
Why This Matters:
The Supreme Court's decision represents a fundamental recalibration of how states balance competing constitutional principles in redistricting. By requiring evidence of intentional discrimination rather than accepting statistical patterns alone, the Court has restored greater deference to elected state legislatures in drawing district boundaries. This shift acknowledges that partisan considerations are legitimate factors in redistricting, particularly after the seventh year since the Court ruled federal courts cannot police partisan gerrymandering. The heightened evidentiary standard—requiring "smoking gun" evidence of discriminatory intent—reflects the reality that explicit racial discrimination in redistricting has become exceedingly rare in modern governance. For fiscal conservatives, the ruling may reduce costly litigation over redistricting plans. The decision's protection of partisan mapmaking could solidify Republican gains in the House while potentially exposing Democratic-drawn maps to legal challenge, fundamentally reshaping the political landscape for the 2028 election cycle and the redistricting that will follow the 2030 census. The practical effect is to return significant power over electoral boundaries to state legislatures, reinforcing principles of federalism and local control over election administration.
