Redistricting Tracker: 9 States Vote on New Maps in 2026

The maps on this page are the ones voters use on November 3, 2026. See what is on the ballot that day.

District lines are normally redrawn once a decade, after each census. That pattern broke in the current cycle. Since the summer of 2025, 10 states have changed their congressional maps between censuses: Alabama, California, Florida, Louisiana, Missouri, North Carolina, Ohio, Tennessee, Texas and Utah. Nine of those maps are in use for the November 3, 2026 election. Missouri votes on its 2022 lines: on September 25, 2026 the U.S. Supreme Court stayed two Eighth Circuit orders in People Not Politicians v. Onder (No. 26A388) and said that as a matter of state law the 2022 map must be used this year. Voters will decide the 2025 map as Proposition A.

This page lists what changed in each state, who changed it, and where the litigation stands. Every entry was checked against a source on September 26, 2026.

What the maps on this site show

District pages on this site show the boundaries of the 119th Congress, which are the districts the sitting members were elected to represent. New lines take effect with the November 3, 2026 election, and the members elected under them take office in January 2027.

For the 9 states with new lines, the site also carries the 2026 maps. Enter a ZIP code or street address in the district lookup and the result adds a line that says which district you vote in on November 3, 2026. Each district page in those states lists the 2026 districts its residents vote in, with each one’s share of the population and the candidates on its ballot. The 2026 layer comes from the Census Bureau block file for the 120th Congress, checked against the plan files the states published. How we source our data lists every file and how it was checked.

A ZIP code result is approximate when the new lines split the ZIP code, so the lookup shows each district’s share of that ZIP code’s residents. A full street address gives one district. The state’s own voter lookup is final, and every result links to it. Missouri votes on its 2022 lines on November 3, 2026, which are the districts its pages already show, so it has no 2026 layer.

The 10 states

Alabama

Alabama did not pass a new map in this cycle. On June 2, 2026 the U.S. Supreme Court granted stays in Allen v. Milligan, Allen v. Singleton and Allen v. Caster, lifting the injunctions that had required the court-drawn remedial map used in 2024. The effect is that the map the legislature passed in 2023 is the one in use for the November 2026 election. The 2023 map does not include the second opportunity district the courts had required, which the court-drawn map used in 2024 did. The stays remain in place while the U.S. Supreme Court acts on the state’s appeal, and the case has not been decided on the merits. See Alabama congressional districts.

California

Voters approved Proposition 50 on November 4, 2025 by 64.4 percent to 35.6 percent. The measure enacted a legislature-drawn map that temporarily sets aside the Citizens Redistricting Commission map through 2030. It was drawn to add 5 Democratic-leaning seats. The map is in effect and Ballotpedia tracked no lawsuit against it. See California congressional districts.

Florida

The legislature passed a new map and Governor Ron DeSantis signed it on May 4, 2026. Reporting on the map describes it as shifting 4 districts held by Democrats toward Republicans based on 2024 presidential results. The Florida Supreme Court rejected a challenge in June 2026 and the map is in effect. See Florida congressional districts.

Louisiana

The legislature passed Senate Bill 121 and Governor Jeff Landry signed it on May 29, 2026, after the U.S. Supreme Court decision in Louisiana v. Callais. The map reduces the number of majority-Black districts from 2 to 1 out of 6. Lawsuits were filed after enactment and had not been resolved when this page was checked. See Louisiana congressional districts.

Missouri

Governor Mike Kehoe signed House Bill 1, the map known as Missouri First, on September 28, 2025 after a special session. It targeted the 5th District and was described as adding 1 Republican-leaning seat. The map was used in the August 2026 primary. Opponents submitted more than 300,000 referendum signatures, Secretary of State Denny Hoskins rejected the petition on primary election day, and a lower court agreed with him. On September 3, 2026 the Supreme Court of Missouri reversed that decision unanimously. It held that the referendum petition was legal, sufficient and timely, that House Bill 1 never took effect, and that the map drawn after the 2020 census remains in force for the November 2026 general election. The court also ordered a statewide vote on the new map. Attorney General Catherine Hanaway appealed to the U.S. Supreme Court, which twice declined to disturb the state court ruling. On September 21, 2026 a panel of the 8th U.S. Circuit Court of Appeals ordered the 2025 map back into use. On September 25, 2026 the U.S. Supreme Court stayed that order in People Not Politicians v. Onder, No. 26A388, saying that as a matter of state law the 2022 map must be used in the 2026 congressional election. Ballots on the 2022 lines had already been printed and mailed, and absentee voting had begun. Missouri votes on its 2022 map on November 3, 2026, and voters will also decide Proposition A, a referendum on whether to approve House Bill 1. See Missouri congressional districts.

North Carolina

The General Assembly passed a new map on October 21 and 22, 2025. North Carolina does not require the governor to sign a redistricting bill. The map redraws the 1st District and is described as adding 1 Republican-leaning seat. A federal court allowed its use for 2026 on November 26, 2025 in Williams v. Hall, with litigation continuing. See North Carolina congressional districts.

Ohio

The Ohio Redistricting Commission adopted a new map unanimously on October 31, 2025. The commission drew it because the legislature missed its September 30, 2025 deadline and the 2021 map expired under the state constitution. The delegation moves from 10 Republicans and 5 Democrats to a map drawn for 12 and 3. Ballotpedia tracked no lawsuit against it. See Ohio congressional districts.

Tennessee

The legislature met in a special session and Governor Bill Lee signed a new map on May 7, 2026. It splits the Memphis area and is described as adding 1 Republican-leaning seat. A three-judge federal panel denied a preliminary injunction in July 2026, so the map is in use while the case continues. See Tennessee congressional districts.

Texas

Governor Greg Abbott signed House Bill 4 on August 29, 2025, drawn in a special session he called in July 2025. It is described as adding 5 Republican-leaning seats. A district court blocked it in November 2025, the U.S. Supreme Court stayed that ruling on December 4, 2025, and the Court upheld the map on April 27, 2026. See Texas congressional districts.

Utah

Utah’s map came from a state court, not the legislature. Judge Dianna Gibson struck down the 2021 map on August 25, 2025, and on November 10, 2025 she selected the plaintiffs’ map rather than the one the legislature submitted. The map consolidates Salt Lake City and creates 1 Democratic-leaning district out of 4. A three-judge federal panel declined to overturn it on February 23, 2026. See Utah congressional districts.

States where an effort failed

Redistricting efforts in this cycle did not produce a new map everywhere they were attempted. Indiana rejected a redraw in December 2025, Virginia’s effort was struck down in May 2026, and South Carolina’s did not advance. Those states use the maps they had.
