The US Supreme Court is poised to consider further cutting a landmark 1965 civil rights law with a case that could boost Republican election hopes and call into question as many as 19 congressional districts with primarily Black or Hispanic populations.
In an unusual re-argument of a Louisiana redistricting clash Wednesday, the conservative-dominated court will weigh GOP calls to undercut the most significant remaining part of the Voting Rights Act, a law that was passed to address rampant discrimination against Black voters, particularly in the South. The justices have already significantly diluted the law twice since 2013.
The court is considering whether the Constitution permits the intentional creation of heavily Black or Hispanic districts to ensure that minority voters can elect candidates of their choice. A ruling that it doesn’t would be a boon for Republicans given that these districts tend to vote Democratic.
“The stakes are enormous,” said
The Supreme Court for decades has said that Section 2, which outlaws election rules that discriminate on the basis of race, often requires majority Black or Hispanic districts to ensure the votes of racial minorities aren’t diluted. But the justices in August said they will consider whether the practice is now unconstitutional.

Democrats are hoping to capitalize on voter dissatisfaction with the current administration to gain seats in Congress during the 2026 vote, but may be stymied by Republican efforts to redraw districts to favor GOP candidates in several states.
A new study by the progressive groups Fair Fight Action and Black Voters Matter Fund concluded that a decision overturning or weakening Section 2 could let Republicans redraw 19 House districts that are currently protected under the Voting Rights Act. The vast majority of those seats are currently held by Democrats.

Protecting Johnson
The latest clash stems from a twisting, years-long fight. Louisiana drew its lines in response to a lower court decision that said the state probably needed a second majority-Black district to comply with the Voting Rights Act. Louisiana has six congressional seats and a 33% Black population.
Louisiana lawmakers then drew a new 6th District, which runs a jagged 250-mile course from Shreveport to Baton Rouge, scooping in heavily Black areas along the way. The map preserved the districts of key Republicans, including House Speaker
A different group of Louisiana voters then opened a new front. Describing themselves as “non-African Americans,” the voters sued on the grounds that Louisiana had violated the Constitution’s equal protection clause by relying too heavily on race.
A three-judge panel declared the new map unconstitutional, and that case is now before the nation’s highest court. The court was scheduled to rule in the nine-month term that ended in late June but, in an unusual move, instead said the justices would hear a second argument to consider the broader constitutional issues.
The court’s re-argument decision prompted Louisiana to switch sides in the case. The state originally defended the map but now says the justices should invalidate it.
“It’s always been offensive to our legislature to be told to go out and sort your voters by race,” Louisiana Attorney General Elizabeth Murrill, a Republican, said in an interview. “It’s asking them to intentionally racially classify our voters.”

Republicans are already engaged in unusual mid-decade redistricting efforts, redrawing the congressional maps in Texas and Missouri to turn a total of six seats into likely GOP pickups. Depending on how quickly the court rules, it could supercharge that process, prompting other Republican-held states to quickly redraw their maps in time for next year’s election.
Hasen, the UCLA professor, said he was struck by the court’s decision to hear arguments during the first sitting of its new term. The timing, he said, “suggests the court wants to at least have the option of getting an opinion out fast enough to affect the 2026 elections.”
The case is Louisiana v. Callais, 24-109.
