Tennessee, Alabama rush to redraw House maps after Supreme Court weakens Voting Rights Act

They had a narrow window before courts might step in
Republican governors rushed to redraw maps after the Supreme Court weakened voting rights protections.

In the days following a Supreme Court ruling that narrowed the Voting Rights Act's protections, the governors of Tennessee and Alabama summoned their legislatures into special session to redraw congressional maps before the 2026 elections. The decision in Louisiana v. Callais raised the threshold for challenging racially drawn districts, and Republican-led states moved swiftly to reshape political boundaries that had long been contested terrain. What is unfolding is an old American struggle — over who draws the lines, and whose voice those lines are drawn to contain.

  • The Supreme Court's 6-3 ruling in Louisiana v. Callais dramatically raised the legal bar for challenging maps that dilute Black voting power, requiring proof of intentional discrimination rather than disparate effect.
  • Within hours of the ruling, Republican governors in Tennessee and Alabama called emergency legislative sessions, targeting Democratic-held districts in Memphis and Alabama's majority-Black congressional seats.
  • Alabama's Attorney General moved to vacate a standing court injunction that had required a fairer map through 2030, betting the new ruling would override years of hard-won litigation.
  • The redistricting wave is spreading — Mississippi, Florida, Texas, and other states are already redrawing or planning to redraw maps, with Republicans racing to lock in advantages before the 2026 midterms.
  • Courts remain the last check, but with the legal landscape fundamentally shifted, the question is no longer whether these maps will be redrawn — it is whether any institution will move fast enough to stop them.

On a Friday in early May, the Republican governors of Tennessee and Alabama each called their state legislatures back into special session. They were responding to a Supreme Court ruling — Louisiana v. Callais — that had just narrowed a foundational protection in the 1965 Voting Rights Act, making it far harder to challenge congressional maps that diminish the political power of Black voters. Both governors moved within hours.

In Tennessee, Governor Bill Lee framed the session in measured language, saying maps should reflect the will of voters. But the intent was plain: Tennessee's lone Democratic congressional district, centered in Memphis and held by Representative Steve Cohen, was in the crosshairs. Senator Marsha Blackburn had already called for its elimination, and President Trump had publicly urged Lee to redraw the map for an additional Republican seat. The state's August primaries added a logistical wrinkle — candidates had already qualified under the old map.

Alabama's situation carried more legal weight. Governor Kay Ivey's session targeted the state's two majority-Black districts, both held by Democrats — seats that existed only because a federal court had struck down an earlier Republican-drawn map as a Voting Rights Act violation. Now, Alabama's Attorney General asked the Supreme Court to vacate that lower court ruling and restore the old map. A standing injunction required the current boundaries to remain through 2030, but officials were betting the new ruling would override it.

The Supreme Court's decision had rewritten the rules across the board. Justice Samuel Alito's majority opinion held that districts only violate the Voting Rights Act when there is a strong inference of intentional discrimination — a threshold far higher than what the law had previously required. Louisiana, whose map had triggered the case, immediately postponed its own House primaries.

The effects spread quickly. Mississippi weighed targeting Representative Benny Thompson's seat. Florida had already begun redrawing its map, now with fresh legal cover. Texas, Missouri, North Carolina, and Virginia had each redrawn mid-decade in recent years. The 2026 midterms were taking shape on ground that one party was actively — and legally — reconfiguring.

Whether courts would intervene remained uncertain. Some injunctions were still technically in force. But Republican legislatures were moving fast, and the legal landscape that had once constrained them had fundamentally shifted.

On Friday, the Republican governors of Tennessee and Alabama each picked up the phone and summoned their state legislatures back to work. Bill Lee in Tennessee and Kay Ivey in Alabama were responding to a Supreme Court decision handed down earlier in the week—one that fundamentally altered how states can draw congressional districts. The ruling, in a case called Louisiana v. Callais, had just narrowed a key protection in the 1965 Voting Rights Act, making it significantly harder to challenge maps that dilute the voting power of Black Americans. Within hours, both governors were moving to redraw their congressional boundaries before the 2026 midterm elections.

Lee's special session in Tennessee would begin the following Tuesday. In his statement calling lawmakers back, he framed the effort in neutral language—the maps needed to "accurately reflect the will of Tennessee voters." But the subtext was clear. Tennessee currently has one Democratic congressional district, centered in Memphis and represented by Steve Cohen. Republican Senator Marsha Blackburn, who is running for governor, had already called on lawmakers to eliminate that seat entirely, drawing a map that would give the GOP all nine of Tennessee's House districts. President Trump had made his own preference known, urging Lee to redraw the map to hand Republicans "one extra seat." The state's primary elections were scheduled for August 6, though candidates had already qualified for the ballot back in March—a timing problem that would need solving if new maps were adopted.

Alabama's situation was more tangled. Governor Ivey called her special session to begin Monday, ostensibly to prepare for potential special primary elections if the House map changed. But the real target was Alabama's two majority-Black congressional districts, both held by Democrats. Years of litigation had produced the current map, which emerged from a court order after a three-judge panel found that Alabama's 2023 map—drawn by Republican lawmakers—violated the Voting Rights Act by packing Black voters into a single district. The court had then drawn a new map with two districts where Black voters made up a significant portion of the electorate. Now, with the Supreme Court's ruling in hand, Alabama's Attorney General Steve Marshall asked the high court to vacate that lower court decision and allow the state to return to the 2023 map, which had only one majority-Black seat. A court injunction issued the previous year had required Alabama's current map to stay in place until after the 2030 Census, but Marshall was betting the Supreme Court's new ruling would override that.

The Supreme Court's decision in Louisiana v. Callais had rewritten the rules. In a 6-3 ruling, the court struck down Louisiana's map, which included two majority-Black House districts, finding that state lawmakers had relied too heavily on race in drawing it. More significantly, Justice Samuel Alito's majority opinion narrowed the Voting Rights Act itself. Previously, the law had been read to require states to draw districts where minority groups made up a majority in certain circumstances. Now, districts would only violate the act if there was a "strong inference that intentional discrimination occurred"—a much higher bar. Louisiana officials had already postponed their House primaries scheduled for later that month, signaling they would redraw their map.

The ripple effects were spreading across the South and beyond. Mississippi lawmakers were planning a special session to redraw state Supreme Court districts, with some officials suggesting they also target the U.S. House map to unseat Democratic Representative Benny Thompson, though the state's election calendar might make that impossible in time for 2026. Florida had already begun efforts to redraw its congressional map, giving Republicans an edge in four additional seats—work that had started before the Supreme Court's ruling but now had legal cover. Texas, Missouri, North Carolina, and Virginia had all undertaken mid-decade redistricting in recent years, each tilting their maps toward their preferred party. The 2026 midterms were shaping up to be fought on terrain that Republicans were actively reshaping.

What remained unclear was whether courts would intervene. The lower court injunction in Alabama was still technically in place. Federal judges in other states might block or delay redistricting efforts. But the Supreme Court's narrowing of the Voting Rights Act had fundamentally shifted the legal landscape, and Republican-controlled legislatures were moving fast to exploit it before courts could act. The question was not whether they would try to redraw the maps—they already were—but whether the judiciary would let them succeed.

Lawmakers owe it to Tennesseans to ensure our congressional districts accurately reflect the will of Tennessee voters.

Why did these governors move so quickly? What was the urgency?

Model

The Supreme Court's ruling changed what they could legally do. Before, challenging a map that hurt Black voters was relatively straightforward under the Voting Rights Act. After, it became much harder. They had a narrow window before courts might step in to block them.

Inventor

So they're trying to eliminate Democratic seats before anyone can stop them?

Model

That's the effect, yes. In Tennessee, they want to erase the one Democratic district. In Alabama, they want to go from two majority-Black districts back to one. The legal cover is the Supreme Court's new standard—they can argue they're not targeting race, just redrawing for other reasons.

Inventor

But isn't that what the Voting Rights Act was supposed to prevent?

Model

It was. The act required states to show they weren't diluting minority voting power. Now the burden has flipped. You have to prove intentional discrimination, which is much harder to demonstrate in court.

Inventor

What happens if courts do intervene?

Model

That's the real uncertainty. Some states might get blocked. Others might succeed. The timing matters enormously—if a court acts fast enough, it could stop a map from being used in 2026. If it moves slowly, the new maps might already be in place.

Inventor

Is this happening everywhere?

Model

No, just in states with Republican control and Democratic seats to target. But it's happening in enough places—Tennessee, Alabama, Mississippi, Florida—that it could shift the balance in the House.
