In the United States, all states with multiple congressional districts are required to revise their district maps following each decennial census to account for population changes. In 2026, most states will use the same districts created in the
redistricting cycle following the 2020 census, which were first used in the 2022 elections. Maps have changed or would change in several states, often due to legal challenges made based on partisan or racial gerrymandering. As of , several states have seen challenges to their
congressional district maps that were put in place during the
redistricting cycle brought upon by the results of the 2020 census. In
Arkansas, a federal court dismissed a case against their congressional map that argued the map did not comply with the
Voting Rights Act. The
Florida Supreme Court dismissed a challenge regarding the Florida's congressional map, finding a new plurality-Black congressional district would be against federal law. In
Georgia, litigation is still ongoing regarding appeals to the newly drawn congressional map that was used in the 2024 elections. However, it was not resolved before the filing deadline for the 2026 Congressional elections. In
Louisiana, litigation remained unresolved. In South Carolina, the
South Carolina Supreme Court ruled that partisan gerrymandering is not in violation of the state's constitution, keeping the maps in place. In
Texas, a trial was held in federal court in
El Paso to determine whether its congressional map discriminated against Black and Latino voters in violation of the VRA, but the case was paused pending expected new maps in the state. In
Utah, a partisan gerrymander case resulted in a map which creates a safe Democratic district comprising the majority of
Salt Lake County following a district court ruling. In
Wisconsin, a challenge to the state's current congressional map, arguing it was an unlawful partisan gerrymander, was dismissed by the
Wisconsin Supreme Court. A new map was required in
Ohio due to the Congressional Redistricting Procedures Amendment to Section XI of the
state's constitution, resulting in two districts becoming more Republican leaning. On November 18, a panel of the
District Court for the Western District of Texas issued a preliminary injunction blocking the new map, putting the former map back in place but the Supreme Court later placed an administrative stay on the ruling, allowing the new maps to stand.
Governor Ron DeSantis has expressed interest in redrawing
Florida's congressional map, and the Florida House has created a special redistricting committee.
Governor Mike Kehoe of
Missouri called a special session on August 29, 2025, which redrew the solid Democratic
5th district to a solid Republican district, allowing the GOP to pick up a seat. Republican state legislative leaders in
North Carolina announced a redraw of the state's congressional districts to make the 1st congressional district more Republican leaning. Democratic governor
Wes Moore of
Maryland unsuccessfully pursued redistricting in his state.
