Supreme Court ruling sparks GOP redistricting push across Southern states

Potential dilution of Black voter representation and Democratic electoral power across multiple southern states and local jurisdictions.
This is an explosive move to turn the clock back all the way pre-1965
Democratic Rep. Troy Carter on the scope of the redistricting effort beyond Congress to local elections.

A Supreme Court ruling narrowing Voting Rights Act protections for majority-minority districts has set in motion a rapid Republican effort to redraw congressional maps across five southern states, targeting seats long held by Black Democrats. The decision, rooted in Louisiana's congressional boundaries, has reopened a question America has wrestled with since Reconstruction: who draws the lines, and whose voice disappears when they do. While legal doctrine, calendar constraints, and electoral uncertainty may blunt the immediate impact, the longer arc bends toward a 2028 reckoning that could fundamentally alter the composition of southern representation.

  • Within hours of the ruling, Republican governors and legislators in Louisiana, Florida, Tennessee, Mississippi, and Alabama moved to call special sessions and redraw maps, sensing a rare legal opening to consolidate power.
  • Louisiana suspended its own House primary elections mid-cycle, with ballots already printed and early voting days away — a disruption that Democratic Representative Troy Carter called a move to 'turn the clock back all the way pre-1965.'
  • Florida, Tennessee, and Mississippi each advanced plans that could eliminate majority-Black districts in Memphis, Tampa, Orlando, and the Mississippi Delta, directly targeting long-serving Black Democratic incumbents.
  • Courts, candidate filing deadlines, and the Purcell principle — which bars last-minute election rule changes — stand as the primary guardrails against immediate Republican gains in 2026.
  • Analysts and strategists on both sides acknowledge the full force of the ruling may not land until 2028, when redistricting can proceed without the pressure of an imminent election cycle.
  • Beyond Congress, Democratic officials warn the erosion of majority-minority districts threatens representation at every level — school boards, city councils, and state legislatures across the South.

On Wednesday, the Supreme Court handed down a ruling that narrowed the Voting Rights Act's protections for majority-minority districts, and within hours, Republican officials across five southern states began moving to redraw their congressional maps.

Louisiana acted first. Governor Jeff Landry signed an executive order encouraging the legislature to pass new maps immediately, then suspended the state's House primary elections — even as ballots had already been printed and early voting was days away. The old map had created two Democratic-leaning, majority-Black districts; a redrawn version could eliminate one, potentially delivering Republicans one or two additional seats. Democratic Representative Troy Carter warned the consequences would reach far beyond Congress, touching school boards, city councils, and legislative seats statewide. 'This is an explosive move to turn the clock back all the way pre-1965,' he said.

Florida's Governor Ron DeSantis had anticipated the ruling. His legal team had prepared a map designed to add four Republican-leaning seats by dismantling Democratic districts in Tampa, Orlando, and the southeast coast — and his counsel argued the decision freed Florida from its own state constitution's fair-districting requirements. In Tennessee, Governor Bill Lee called a special session after Senator Marsha Blackburn proposed a map that could produce a nine-to-zero Republican advantage by breaking apart Memphis's majority-Black 9th District. President Trump publicly endorsed the effort. Mississippi and Alabama followed, with state officials in both cases making little effort to conceal their intent to eliminate majority-Black Democratic seats.

Yet the path to immediate gains proved complicated. Many states had already passed primary deadlines, legal challenges were certain, and the Purcell principle — a federal doctrine barring last-minute changes to election rules — loomed over every rushed timeline. Analysts noted that even newly drawn Republican-leaning districts might not be safe enough in an uncertain political environment, raising the question of whether waiting for 2028 would serve the party better.

A CBS News analysis estimated Republicans could gain between one and nine seats across the five states in 2026, with that number expected to grow substantially in the next redistricting cycle. For now, the South's political map remained unsettled — and the representation of Black voters in Congress and in local government hung in the balance.

On Wednesday, the Supreme Court handed down a decision that would reshape the political map of the American South. The ruling, centered on Louisiana's congressional districts, narrowed the protections that the Voting Rights Act had long provided to majority-minority districts—the kind of districts designed to ensure that Black voters, historically diluted and marginalized, could elect representatives of their choosing. Within hours, Republican officials across five southern states began moving to redraw their congressional maps, sensing an opportunity to convert the Court's logic into electoral gains.

Louisiana moved fastest. The state's Secretary of State certified an emergency on Thursday, and Governor Jeff Landry signed an executive order encouraging the legislature to pass new maps immediately. The timing was urgent: early voting for the state's May 16 House primary was set to begin May 2, and ballots had already been printed. Landry suspended the House primary elections and told voters they would see notices at polling places. The old map, which the Court had struck down, had created two Democratic-leaning, majority-Black districts. A redrawn map could eliminate one of them, potentially adding one to two Republican seats. Louisiana's population is nearly one-third Black, but under the new legal landscape, state Republicans saw a path to six congressional districts with no African-American or Democratic representation. Democratic Representative Troy Carter told CBS News the implications extended far beyond Congress—to school boards, city councils, and legislative seats across the state. "This is, in fact, an explosive move to turn the clock back all the way pre-1965," he said.

Florida's Republican Governor Ron DeSantis had already anticipated the ruling. His counsel had been preparing a map designed to add four more Republican-leaning seats by eliminating or shrinking Democratic districts in Tampa, Orlando, and the state's southeast coast. DeSantis's general counsel argued that the Supreme Court's decision meant Florida no longer had to follow its own state constitution's "Fair Districts" amendments, which had required consideration of race in drawing lines. The map was awaiting the governor's signature. Democratic election lawyer Marc Elias pledged to challenge it in court.

Tennessee's Republican Governor Bill Lee called a special legislative session for Tuesday to redraw the state's congressional districts. U.S. Senator Marsha Blackburn, running for governor, had already proposed a map that could produce a nine-to-zero Republican advantage by breaking up Tennessee's 9th District, which encompasses Memphis and has a substantial Black voter population. State Representative Johnny Garrett threw his support behind the proposal, writing on social media that Tennessee should support "Trump's America First agenda" by eliminating longtime Democratic Representative Steve Cohen. President Trump weighed in, saying he had called Lee and was told the governor would "work hard to correct the unconstitutional flaw." Trump wrote: "This should give us one extra seat, and help Save our Country from the Radical Left Democrats."

Mississippi and Alabama followed. Mississippi's Republican Governor Tate Reeves announced a redistricting session for May 20, ostensibly to redraw state Supreme Court districts but potentially to target the state's 2nd Congressional District, a majority-Black seat held by Democratic Representative Bennie Thompson. Republican state officials made their intent clear. State Auditor Shad White wrote that the ruling "likely opens the door to redrawing Mississippi's congressional districts." State Senator Kevin Blackwell was more direct: "It's time to erase Bennie Thompson's District." Alabama's Governor Kay Ivey initially hesitated but reversed course, calling a special session so lawmakers could prepare for potential redistricting if courts allowed the state to return to its 2023 map.

Yet significant obstacles stood in the way of Republican gains in 2026. Many states had already held primary elections or passed candidate filing deadlines. Legal challenges were certain, and the federal courts had established the "Purcell principle"—a doctrine preventing changes to voting rules too close to an election. Michael Li, senior counsel at the Brennan Center's Democracy Program, noted another constraint: the political environment. "If you draw a Trump +7 district or even a Trump +10 district, that may not be enough," he said. "So why not wait till an election cycle in 2028 that might be better for your party?" A CBS News analysis suggested that across all five states, Republicans could gain between one and nine seats in 2026, with that number expected to grow substantially in 2028 as more states redrew their lines without the time pressures of an imminent election.

What unfolded in those first days after the Supreme Court's decision was a coordinated Republican effort to capitalize on a legal opening. But the calendar, the courts, and the uncertainty of future electoral conditions all suggested that the full impact of the ruling would not be felt until the next redistricting cycle. For now, the South's political map remained in flux, with Democratic representation—particularly in the Congressional Black Caucus—facing erosion that extended beyond Congress to school boards, city councils, and state legislatures across the region.

We can realistically end up having six congressional districts with no African-American, or Democratic representation, it's very possible.

Why did the Supreme Court's decision on Louisiana matter so much that governors started calling special sessions within days?

Model

The ruling narrowed the legal protections that had required states to create districts where Black voters could actually elect their preferred candidates. Once those protections weakened, Republican officials saw they could redraw maps to dilute Black voting power without the same legal risk they'd faced before.

Inventor

So they could have done this before, but the law stopped them?

Model

Exactly. The Voting Rights Act had required states to show that their maps didn't discriminate based on race. The Court's decision essentially said that requirement was too strict. It opened a door that had been legally locked.

Inventor

Why didn't they all just redraw immediately?

Model

Time. Most states had already held primaries or passed filing deadlines. You can't change the rules days before an election—the courts won't allow it. That's the Purcell principle. So Louisiana had to scramble to suspend its primary. Others realized they'd have to wait until 2028.

Inventor

What happens to the people in those districts if the maps change?

Model

If a majority-Black district gets carved up and split into several districts where Black voters are a minority, they lose the power to elect someone who represents their interests. Their votes get diluted across districts where they can't form a majority.

Inventor

Is this just about Congress?

Model

No. Democratic Representative Troy Carter pointed out it affects school boards, city councils, state legislatures—anywhere districts are drawn. The principle applies everywhere.

Inventor

Will the courts stop them?

Model

Almost certainly there will be legal challenges. But the Supreme Court just weakened the tool that had been used to stop this before. So the outcome is genuinely uncertain now.
