Republican-led legislatures across the South are racing to redraw their congressional maps after the Supreme Court struck down Louisiana's second majority-Black district as an unconstitutional racial gerrymander, a ruling that has already delayed elections, triggered special sessions, and set off a multistate scramble that could reshape the U.S. House ahead of November.
In the span of a single week, Tennessee signed a new map into law, Alabama passed legislation to hold fresh primaries under a friendlier map, Louisiana began public hearings on replacement lines, and South Carolina's House voted to extend its legislative calendar to keep the door open for its own redraw. Democrats, meanwhile, filed lawsuits and took to social media to protest what they call a coordinated effort to strip Black voters of representation.
The pace is extraordinary. The Hill reported that the moves threaten to unseat multiple House Democrats and advance the GOP's goal of protecting its slim House majority through the 2026 midterms. For Republicans, the court's decision removed a legal barrier that had forced several Southern states to draw majority-minority districts under Section 2 of the Voting Rights Act. For Democrats, it gutted a tool they had relied on for decades to secure minority representation in Congress.
Late last month, the Supreme Court ruled that Louisiana's addition of a second majority-Black congressional district amounted to an unconstitutional racial gerrymander. The justices upheld a prior federal court decision that had barred Louisiana from using a Legislature-drawn 2024 map, which included a district stretching from Shreveport to Baton Rouge.
The decision, authored by Justice Samuel Alito in a 6-3 split, significantly narrowed the scope of Section 2 of the Voting Rights Act, making it harder for voters to challenge maps that dilute minority voting power. Louisiana Gov. Jeff Landry framed the outcome in stark terms: "I think that the Supreme Court has finally taken race out of redistricting."
That framing, race out, partisanship in, captures the core of the debate. As we previously covered, the ruling sent shockwaves far beyond Louisiana, prompting Democratic leaders in states like California to voice alarm about the precedent it set.
Louisiana moved first. Officials delayed House primaries, originally set to begin May 16, until July 15 or "such time as determined" by the state Legislature. A state Senate committee began hearing public comment on redistricting on Friday, and the full Legislature is expected to vote on new maps next week.
The stakes are direct. Rep. Cleo Fields, one of two Democrats in Louisiana's six-member House delegation, currently represents the district the court invalidated. A new map could eliminate his seat or redraw it beyond recognition.
Justin Levitt, a constitutional law professor at Loyola Law School who maintains the website All About Redistricting, questioned the legal basis for Louisiana's approach. He told The Hill:
"In Louisiana in particular, the governor sort of declared an emergency, but only for some races on the ballot, which shows you that there isn't an emergency, because if there were a real emergency, you wouldn't stop the voting for just some of the races."
Levitt also warned about the broader constitutional implications of halting elections already in progress: "There are very real constitutional problems with stopping an election in progress."
Alabama Republicans approved legislation on Friday directing the governor to schedule new primary elections this year under a GOP-friendly map, but only if courts lift an existing injunction. That injunction currently requires the state to keep its map, which includes a second district where Black voters make up close to a majority, in place until after the 2030 census.
The bill would allow the governor to ignore the May 19 primary date for some congressional districts and hold a new election. The map Republicans want to implement was previously rejected by a federal court in 2023. Whether the court will now lift the injunction remains, in the words of Geoffrey Skelley, chief elections analyst at Decision Desk HQ, "up in the air."
Rep. Shomari Figures, a Democrat, won his seat in 2024 under the current court-ordered map. If Alabama succeeds in reverting to the old lines, his district could vanish. Demonstrators gathered outside the Alabama Statehouse to oppose the effort.
Jared Leopold, a Democratic strategist, cast the Alabama push in historical terms: "This is not just a one-election issue. This is, from a historical perspective, your Republican legislators are effectively trying to get rid of Black representation in Congress, and that is going to have some serious implications that go beyond any one election."
As we detailed earlier, the coordinated speed of these efforts across Alabama, Tennessee, and South Carolina has few modern precedents in redistricting fights.
Tennessee moved the fastest. Gov. Bill Lee called a special session on redistricting the previous week, and by Thursday, lawmakers had approved a new congressional map. Lee signed it into law the same day.
The new map splits Rep. Steve Cohen's Memphis-based 9th Congressional District into three separate districts. It also divides Nashville into five districts. Cohen, the lone Democrat in Tennessee's nine-member House delegation, has represented his district for nearly two decades.
Cohen responded on social media Thursday:
"And just like that, the TN GOP voted to enforce a racial gerrymander of Memphis and strip our city of effective representation for decades."
He added: "Next stop is the courts." The Tennessee Democratic Party made good on that promise, filing suit on Friday to block the state from using the new districts until after this year's elections.
President Trump had publicly touted Gov. Lee for agreeing to "work hard to correct the unconstitutional flaw in the Congressional Maps of the Great State of Tennessee." The language frames the redraw not as partisan aggression but as compliance with the Supreme Court's ruling, a framing Democrats reject outright.
Justice Clarence Thomas, in his own concurrence with the Louisiana ruling, went further than the majority in calling for the dismantling of race-based redistricting altogether, a position that we explored in depth and that has emboldened state-level Republican action.
South Carolina Republicans took a more cautious step. State House lawmakers voted this week to extend their legislative calendar, leaving the door open to drawing new congressional lines. But the extension must also pass the state Senate, which adjourned Thursday without taking up the matter. Senators are expected to consider it next week.
Rep. James Clyburn, the lone Democrat representing South Carolina in the House, posted a series of messages on X opposing the effort:
"Republicans in the South Carolina state legislature began the process of extending their session to allow for the redrawing of the state's congressional map, with one goal in mind: eliminating the state's only Democratic House district that is occupied by a Democrat."
Clyburn also wrote: "Republicans are trying to break apart South Carolina's 6th District. Not because voters demanded it, but because Donald Trump requested it." He urged supporters: "we cannot let them succeed."
If South Carolina successfully redistricts, Republicans are likely to gain a 7-0 advantage in the state's U.S. House delegation. Clyburn's majority-Black 6th Congressional District, which sprawls around Columbia and Charleston, would be the target.
Skelley suggested that political dynamics may push wavering lawmakers into line. "Especially after what we just saw in Indiana, with the state senators mostly losing renomination, that figures in the South Carolina state Legislature are going to be more reticent to cross President Trump on this," he said.
The New York Post reported that Republicans could potentially gain up to 14 U.S. House seats through new maps in states including Louisiana, Tennessee, Alabama, Florida, Texas, and North Carolina. With Republicans holding only a slim House majority, even a handful of additional seats from redistricting could significantly strengthen their position heading into 2026.
David Wasserman, an elections analyst for the Cook Political Report, captured the bipartisan logic at work: "We're in an era of manic redistricting. And if one party doesn't seize the opportunity, the other party will."
That dynamic played out in reverse in Virginia, where the state Supreme Court on Friday invalidated a redistricting plan approved by voters last month. That plan would have expanded Democrats' edge by as many as four seats in Virginia's House delegation. Skelley noted: "For Democrats, it had been a lot more certain that they would have long-term gains from Virginia. Now that's gone."
The broader consequences of the redistricting wave are still unfolding, and the legal and political environment around it remains volatile. As we previously reported, Southern GOP governors moved quickly after the ruling to begin the process, and the pace has only accelerated since.
Lawsuits are already stacking up. Tennessee Democrats filed suit on Friday. Alabama's legislation hinges on a court lifting an existing injunction. Louisiana's entire primary schedule depends on a map that hasn't been drawn yet. And South Carolina's effort may never reach the governor's desk if the Senate balks.
Levitt warned that the situation is likely to get worse before it stabilizes:
"I think we haven't seen the worst of it yet, and I think there are a lot of other states that are feeling enormous amounts of pressure to join the race to the bottom."
Skelley agreed that the redistricting conflict is "far from over." Changes to maps and primary dates just months before November's general elections would present serious logistical hurdles, for election administrators, candidates, and voters alike.
Just The News reported that Florida has already approved new districts that could help the GOP win up to four additional House seats, a sign that the redistricting wave extends well beyond the four states currently in the spotlight.
Democrats are calling this a power grab. Republicans say they are following the Supreme Court's lead and correcting maps that were drawn on the basis of race rather than law. Both sides have political incentives to act fast. But the court's ruling is clear: race cannot be the predominant factor in drawing district lines, and maps that used it that way were unconstitutional.
The left spent years demanding that legislatures draw districts around racial demographics. The Supreme Court said no. Now the same people who championed race-conscious mapmaking are furious that states are following the court's instructions, and doing so in ways that happen to benefit the party that controls those legislatures.
If Democrats wanted durable maps, they should have drawn legal ones. They didn't. And now they're learning that when you build your political infrastructure on a constitutional violation, the correction is going to sting.
