See Where the Gerrymandering Wars Have Redrawn U.S. Congressional Maps

The nationwide gerrymandering battle has escalated in recent weeks, after a landmark Supreme Court ruling in April weakened the Voting Rights Act and set off a scramble to redraw maps in some Southern states that have yet to hold primaries.

Eight states have redrawn their congressional districts since President Trump pressured Texas lawmakers last summer to pass a new map favoring Republicans. Republican lawmakers in two states are pushing to use a new map ahead of November’s midterm elections.

Here is a look at how district lines have changed in each of the states that have redrawn maps, and how the new maps would have fared in the 2024 presidential election.

Gov. Gavin Newsom and Democratic state lawmakers moved quickly to redraw California’s congressional districts in response to Texas’ gerrymandered map. The new California map, which lawmakers approved in August and voters passed in November of last year, was designed to flip five red districts.

The Supreme Court upheld the map in February, dismissing Republican claims that the state’s new district boundaries illegally favored Latino voters.

Florida’s Legislature passed a new map just days after the Supreme Court ruling on the Voting Rights Act. The map creates four more Republican-leaning House seats, splitting up a Democratic-leaning district in the Tampa area and eliminating a Democratic-leaning district in the Orlando area.

In late September, Gov. Mike Kehoe, a Republican, signed into law a new map that slices the Democrat-leaning core of Kansas City into districts with heavily Republican rural areas. Republicans hope to add one Republican seat, ousting longtime Representative Emanuel Cleaver and leaving the state with just one solidly Democratic district in the St. Louis area.

In North Carolina, Republicans control both houses of the legislature and approved a new map in October of last year. The new map could give Republicans an extra seat in the First Congressional District, which previously included all eight of the state’s majority Black counties and was redrawn to include more conservative-leaning counties.

Gov. Josh Stein, a Democrat, cannot veto redistricting plans, per the state Constitution.

Ohio’s bipartisan redistricting commission approved a new map in October of last year that could add up to two Republican seats. The new map dilutes Democrat-held districts near Toledo and Cincinnati.

Unlike many other states pursuing maps ahead of the normal timeline, Ohio had been required under its state Constitution to redraw its congressional maps before the 2026 midterms.

Tennessee Republicans moved swiftly after the Supreme Court decision that weakened the Voting Rights Act. Gov. Bill Lee signed a new map into law in early May that carves up the only Democratic district in the state, a majority Black district encompassing the Memphis area, splitting it into three neighboring districts.

A coalition of voters and Democratic candidates sued Tennessee officials in federal court over the new map, arguing that it was unconstitutional to implement new district lines this close to the state’s Aug. 6 primary.

Texas was the first state to redistrict last year, after President Trump urged Republican leaders to redraw maps ahead of the midterm elections.

The new map, signed into law by Gov. Greg Abbott in August of last year, could add up to five Republican seats in the state. Democrats argued that the new lines cut into majority Black and Hispanic districts in violation of the Voting Rights Act, but the Supreme Court upheld the map in December.

A Utah state judge in November tossed out a congressional map proposed by the state’s Republican Legislature, instead adopting a map offered by a centrist coalition. That map adds a Democratic-leaning district surrounding Salt Lake City.

Alabama had faced a ban on middecade redistricting until after the 2030 census. But after the Supreme Court ruling on the Voting Rights Act, Republicans in Alabama sought to revert back to a map first proposed in 2023 that had previously been rejected as a violation of the act.

The Supreme Court removed a critical obstacle for the use of that map in May, which would most likely do away with one of two majority-Black districts in the state.

Still, legal challenges remain. A panel of federal judges on May 26 rejected the new map, saying that the districts discriminated against Black people and could not be used so shortly before a vote. Alabama has appealed the ruling to the Supreme Court.

Gov. Jeff Landry, a Republican, delayed House primary elections after the Supreme Court’s decision on the Voting Rights Act tossed out Louisiana’s current maps. Ballots cast in the state’s primaries, where early voting began just days after the decision, did not count. New primary elections will be held in November.

The Louisiana Legislature is continuing to debate a new map, but is expected to eliminate at least one of the state’s two majority-Black districts.
