Redistricting in 2026: Which States Redrew Their House Maps
Reviewed:
House districts are normally redrawn once a decade, after the census. Ahead of 2026, an unusual number of states redrew their maps in the middle of the decade, mostly to gain seats for the party in power in the state. Our results map and who is my representative use the districts that were in effect on November 3, 2026.
Maps in effect for November 2026
| State | Drawn by | Expected effect |
|---|---|---|
| Texas | Legislature (August 2025) | About +5 Republican |
| California | Legislature, approved by voters (Proposition 50, November 2025) | About +5 Democratic |
| Florida | Legislature (May 2026) | About +4 Republican |
| Ohio | Redistricting commission (October 2025) | About +2 Republican |
| North Carolina | Legislature (October 2025) | About +1 Republican |
| Louisiana | Legislature (May 2026) | About +1 Republican |
| Tennessee | Legislature (May 2026) | About +1 Republican |
| Alabama | Legislature's 2023 map, reinstated by the Supreme Court (May–June 2026) | About +1 Republican |
| Utah | State court, choosing a plaintiffs' map (November 2025) | About +1 Democratic |
Ballotpedia's tally of these maps: about +9 Republican on net, before any votes were cast. "Expected effect" is how the new lines were projected to change each party's seats, not a result.
Maps that didn't take effect
- Missouri: the legislature passed a new map in September 2025 that was used in the primaries, but a citizen referendum put it on hold and the 2022 map governed the November election. The referendum is on the ballot as Proposition A.
- Virginia: voters approved a redistricting amendment in April 2026, but the Virginia Supreme Court blocked the new map in May.
- Indiana: the Senate rejected a new map in December 2025. South Carolina's Senate didn't finish one in time. New York's court-ordered change to one district was blocked by the U.S. Supreme Court.
Why the South redrew in 2026
On April 29, 2026, the Supreme Court decided Louisiana v. Callais. It held that Louisiana's second majority-Black district was an unconstitutional racial gerrymander because Section 2 of the Voting Rights Act didn't require it, and it narrowed when Section 2 can require such districts. Several Southern legislatures then redrew their maps for 2026.
Is mid-decade redistricting legal?
Federal law doesn't forbid it, and in 2019 the Supreme Court ruled that federal courts can't police partisan gerrymandering (Rucho v. Common Cause). State constitutions and state courts can set their own limits, which is why some redraws went to state courts or to voters.
