Fifty statehouses fought over their maps in 2025. The line that decided the most was drawn at the Supreme Court — the close of a decade spent dismantling the law that set the limits.
I ◆ The Bench
The decisive redistricting of the decade never passed a legislature. It came from the Supreme Court, which over thirteen years took apart the two legal limits that had governed how maps may be drawn — and left the field open for everything that followed.
The first limit fell in 2013. In Shelby County v. Holder, the Court ended preclearance — the rule that states with a history of discrimination had to clear map changes with the federal government before using them. After that, a state could draw a map and run it; challengers had to sue after the fact and carry the burden themselves.
The second fell this spring. On April 29, 2026, in Louisiana v. Callais, a 6–3 majority gutted Section 2 of the Voting Rights Act — the provision used for sixty years to challenge maps that dilute minority votes. Justice Kagan, in dissent, wrote that the ruling leaves Section 2 close to a dead letter. The weapon had cut both ways: the Biden Justice Department wielded Section 2 against Texas in 2021, and the Trump Justice Department attacked race-conscious districts under the same banner in 2025. The Court ended the argument by taking the weapon off the table.
With the limits gone, the states were free to draw. They did — in a single year, breaking a century-old habit of leaving the map alone between censuses.
II ◆ The Net
Once the constraints were gone, both parties ran the same play — and the maps did not cancel out. Republicans redrew in more states and held what they drew in court; the largest Democratic counter, Virginia's, was struck down before it could take effect. The seat shift the redraws produced on their own moved roughly the margin of House control.
Figures are the seat targets of each enacted redraw, not a forecast. The live, contested tally is tracked below by Cook Political Report and others.
III ◆ The Ledger
The first move. After the President's request, Republicans enacted a new map targeting five Democratic seats. A three-judge panel called it a racial gerrymander that October; the Supreme Court stayed that ruling, so the map stands for November 2026.
A special session took aim at the Kansas City seat held by Emanuel Cleaver, the kind of single-seat redraw the old norm would have ruled out of bounds.
The state's redistricting commission approved a map running 12 Republican to 3 Democratic, up from 10–5, locked in through 2031.
The counter-strike. Voters approved a Democratic map answering Texas seat for seat. Republicans sued; the Supreme Court declined to block it, and the map is cleared for the cycle.
The other one nobody chose. A state court struck Utah's all-Republican 2021 map in August for defying a voter-passed redistricting reform, then in November adopted a plaintiff map gathering Salt Lake City into a single Democratic-leaning seat. A three-judge federal panel declined to block it in February 2026 — Utah's first likely Democratic seat since 2021.
A special session called by the governor added a further bloc of Republican-leaning seats, widening the gap the Democratic counters were trying to close.
The counter that failed. Voters approved a redistricting amendment on April 21 by about three points. The Supreme Court of Virginia voided it on May 8, 4–3, on procedural grounds; the U.S. Supreme Court declined to revive it. The 6–5 map stays for the decade.
The one nobody chose. Louisiana never volunteered to redraw — Louisiana v. Callais forced it, striking the state's second Black-majority district as an unconstitutional racial gerrymander and, in the process, rewriting the rules for every map still standing.
IV ◆ The Terrain
Callais matters more for 2028 than for 2026. The November maps are largely set; what the ruling changes is the ground the next cycle stands on.
With Section 2 spent as a tool for compelling minority-opportunity districts, the majority-minority seats drawn across the South over the past four decades become candidates for redrawing — this time with little legal brake. The courts once compelled many of those districts into being. The doctrine that compelled them is now gone.
The longer shadow falls on 2030. The next census resets every map in the country for the decade after, and it will be drawn into districts without Section 2 standing where it stood for sixty years. The summer's arms race decided a handful of seats. The Court decided the terrain they sit on — and the terrain of the maps that come after.
