A handful of states have placed themselves front and center in a national redistricting battle after Texas took an unusual step to do mid-decade redistricting and advance a friendlier map for Republicans ahead of the 2026 midterms.

The Lone Star State’s map, which Texas Gov. Greg Abbott (R) signed into law on Friday, has prompted red and blue states alike to consider redrawing their own maps. California is the only state so far to tee up a potential new House map ahead of next year in response, where voters will weigh in November whether to pass new congressional lines.

The redistricting tit-for-tat will have major implications for which party controls the House – and whether President Trump could see a check on his power in Congress.

Here’s where key states stand on redistricting:

Texas

The GOP-led state legislature in Texas passed a new set of congressional lines this month, with the intent of giving Republicans the chance to pick up five seats in the midterms – an effort that was driven by Trump and the White House.

Abbott signed the map into law on Friday, but several organizations have already sued the state over the congressional maps, arguing that the map is unconstitutional and violates the Voting Rights Act.

A federal court has already scheduled dates for a preliminary injunction hearing in one of the lawsuits, which will run from Oct. 1 through Oct. 10.

California

California lawmakers advanced a new set of congressional lines aimed at neutralizing expected gains from Texas’ new map, with California Gov. Gavin Newsom (D) signing the bill.

The new House map will go before voters in a special election in November, where a simple majority is needed in order to enact the map before the midterms.

The California Supreme Court has rejected two challenges by Republicans over the new House map, but President Trump has said he intends to sue over them.

Ohio

The Buckeye State was originally the only state expected to redraw its congressional maps this year after the House map used in 2022 didn’t receive bipartisan support.

Republicans will be eyeing the chance to redraw Democratic Reps. Marcy Kaptur’s and Emilia Sykes’ seats to make them even more GOP-friendly. Kaptur’s seat is already Republican-favored, having gone for Trump by close to seven points in 2024 while Sykes’ district evenly split their votes between Trump and former Vice President Harris.

Republicans may also try to redraw Democratic Rep. Greg Landsman’s seat, though his will likely be harder to change given the seat includes Cincinnati.
