A Supreme Court decision that invalidated Louisiana’s 2024 congressional maps has reignited a redistricting battle, after some primary elections have already been held.
In Louisiana v Callias, the Supreme Court ruled that the 2024 map was an unconstitutional gerrymander because it created a second majority-minority district. Gov. Jeff Landry subsequently canceled the primary elections for the House seats, though other primaries are scheduled to continue uninterrupted, with early voting beginning May 9.

Since then, many Republicans have urged their state leaders to take up redistricting efforts as quickly as possible. Tennessee’s governor has already signed a new map for his state.
Before the Louisiana decision, Democrats looked as though they were coming out ahead, with a net +1 seat advantage. However, if southern states pass maps that redraw majority-minority districts, they could have a sizable advantage. Further, the Virginia Supreme Court wiped out the gains Democrats saw there when it struck down the recently passed map that would’ve redrawn four districts in Democrats’ favor.
As it stands, Democrats would gain six seats, and Republicans could gain 10, though that number could rise if Georgia, South Carolina, or Louisiana can instate new maps quickly.
Here are the states that have successfully passed new electoral maps since August:
Texas: Republicans gain five seats
Texas launched the national redistricting fight on July 30, 2025, when it unveiled its proposal for a new congressional map, which stripped Democrats of five seats. Fifty Democratic lawmakers fled the state to deprive Gov. Greg Abbott (R-TX) of his quorum to enact the bill, triggering a standoff that included the issuing of arrest warrants for the rogue lawmakers. The lawmakers soon trickled back, giving Republicans their quorum to vote on the measure in time for the second special session.
The Texas House passed the new map on Aug. 20 in an 88-52 vote, while the Texas Senate passed the map on Aug. 23 by an 18-8 vote. Abbott signed the new map into law on Aug. 29, shifting five congressional seats toward Republicans.
California: Democrats gain five seats
Gov. Gavin Newsom (D-CA) was the first Democratic governor to retaliate against Texas’s redistricting push, quickly unveiling a new map that would shift five of the state’s Republican seats into Democratic hands. His effort was initially met with skepticism from many state Democrats, but nationwide momentum helped push it forward. Newsom called a Nov. 4, 2025, special election to bring the new map before voters, a vote that was easily won in the deep-blue state.
The victory made California the first Democratic state to redistrict in the party’s favor, effectively canceling Texas’s gains.
Ohio: Republicans gain two seats
Ohio was already required by law to redraw its congressional map before the 2026 midterm elections, but Republicans were split over how to configure it. Republican lawmakers debated between two maps — one would have shifted two seats toward the GOP, and the other would have shifted three. The previous map gave Republicans 10 seats and Democrats five seats.
On Oct. 31, 2025, the Ohio Redistricting Commission passed the new map, which shifted two more seats toward Republicans. Democrats agreed to the measure, as it was seen as a compromise to ward off the more aggressive three-seat shift.
North Carolina: Republicans gain one seat
North Carolina‘s previous congressional map gave Republicans 10 seats and Democrats four. The leaders of the Republican-controlled state legislature, House Speaker Destin Hall and Senate President Pro Tempore Phil Berger, unveiled the new map, flipping one seat toward Republicans in October 2025. It moved rapidly through the Senate committee, the full Senate, and then the House over just two days.
North Carolina law gives the state legislature full control over congressional maps, so it was implemented into law upon its passing through the House on Oct. 21.
Missouri: Republicans gain one seat
Missouri Republicans were some of the first to respond to the party’s calls, quickly following Texas’s lead. The previous map gave Republicans six seats and Democrats two. The new map stripped Democrats of one of those, giving the state a 7-1 Republican advantage.
Missouri Lt. Gov. David Wasinger, a Republican, argued that the measure would be in the interest of most Missouri voters, who voted for President Donald Trump by an 18.4-point margin in 2024. He explicitly invoked Trump’s call to redistrict in August 2025.
“We missed the chance to secure a 7-1 map in 2022, a mistake Trump rightly calls on us to fix,” he said. “Missouri’s next congressional map must protect Missouri values and ensure our representatives in Congress are as conservative as the voters who send them.”
The new map was passed in the state legislature with overwhelming majorities, and Gov. Mike Kehoe (R-MO) signed it into law on Sept. 28.
Tennessee: Republicans gain one seat
Gov. Bill Lee (R-TN) signed into law Tennessee’s new electoral map after it was passed by the Republican legislature on May 7. The new map stripped the red state of its single Democratic seat — all nine of its districts now favor Republicans.
The passage was accompanied by a fair amount of drama. Democratic lawmakers blared airhorns, waved signs, shouted down Republicans, and left the chamber in protest. State Rep. Justin Pearson (D), known for being kicked out of the legislature for disruptive behavior previously, was arrested for his rowdy protests.
VIRGINIA VOTERS APPROVE HIGH-STAKES REDISTRICTING REFERENDUM
Utah: Democrats gain one seat
Utah saw the most unique redistricting battle, as Democrats gained a seat in the deep-red state, though not through their own efforts. In August 2025, District Judge Dianna Gibson ruled that the Republican-controlled state legislature had redrawn districts in violation of Utah law, preventing redistricting that favors any party. The previous map gave Republicans all four congressional seats by splitting the blue Salt Lake City among the four districts.
A new map shifting one seat toward Democrats was confirmed in November, after Gibson rejected another proposal that would have made two competitive districts. Republican attempts to block or delay the new map were shot down in February, clearing the way for the 3-1 map favoring Republicans for the midterm elections.
South Carolina and Louisiana: To be decided
Louisiana had its congressional map struck in the Supreme Court’s landmark ruling in late April in Louisiana v. Callais, which held that the state’s creation of a second minority-majority district in compliance with Section 2 of the Voting Rights Act was an unconstitutional racial gerrymander. Gov. Jeff Landry (R-LA) suspended the House primaries, scheduled for May 16, so the districts could be redrawn before the midterm elections. The struck-down map has four Republican seats and two Democratic seats.
The White House is pressuring South Carolina to nix its single Democratic district, but no decision has been made yet. South Carolina’s Gov. Henry McMaster (R) has said changing the maps would weaken Republican support in the other districts.
State Republicans have also urged Georgia’s Gov. Brian Kemp (R) to take up redistricting, but in the final year of his second term, he has so far refused.
Virginia: Court puts hold on maps that gave Democrats four more seats
Democrats scored a victory in Virginia when a redistricting referendum passed in April. However, their efforts were halted after a state Supreme Court ruling reversed the results and reinstated the previous maps to use for the 2026 midterm elections.
The map narrowly passed by voters would’ve implemented a 10-1 map in Democrats’ favor, stripping Republicans of four seats under the previous 6-5 map. The victory would have effectively reversed all Republican gains in redistricting battles so far.
The proposed Virginia map was created by the Democratic General Assembly after a bill temporarily allowed it to redraw congressional districts, ostensibly to counter Republican efforts in other states. The previous 6-5 map, narrowly favoring Democrats, was created by a bipartisan commission.
