Texas Republicans are planning to move forward with redrawing U.S. House district maps, aiming for an increased GOP advantage in the 2026 midterm elections. This comes after state Democrats signaled an end to their two-week walkout.

Meanwhile, California Democrats are also progressing with their own district reshaping to counter Texas’s efforts, initiating a potentially widespread and unusually timed national redistricting clash.

The redistricting process in Texas stalled when several minority Democrats left the state on August 3, mostly relocating to Illinois. These lawmakers indicated their intent to return to Austin after Republican Governor Greg Abbott concluded a special session and California advanced its own redistricting plan.

The Texas House was scheduled to try convening a quorum again Monday.

Governor Abbott included redistricting in the special agenda following encouragement from President Donald Trump, who seeks to fortify the Republicans’ slender majority in the U.S. House to maintain control and support his conservative agenda in the latter part of his tenure.

Normally, redistricting occurs once per decade, aligning with the census, making mid-decade efforts unusual.

Many states, including Texas, give legislators the power to draw maps. California is among those that empower independent commissions with the task.

The country’s two most populous states are leading this intensifying struggle, spreading into numerous court and legislative settings controlled by both parties.

On a national level, the partisan makeup of existing district lines puts Democrats within three seats of a majority. Of the 435 total House seats, only several dozen districts are competitive. So even slight changes in a few states could affect which party wins control.

Texas’ maps would aim to give the GOP five more winnable seats there.

California Democrats, who hold supermajorities in both chambers — enough to act without any Republican votes — on Friday unveiled a proposal that could give Democrats there an additional five U.S. House seats. But any changes would first need the approval of state lawmakers and voters. Democratic California Gov. Gavin Newsom has said that his state will hold a Nov. 4 special referendum on the redrawn districts.
