Moves by Texas Republicans and California Democrats to redraw their U.S. House districts could disrupt a rare partisan balance in American politics.

California Democrats passed a trio of redistricting bills Thursday, a day after Republicans in the Texas House passed new maps of their own.

If approved by voters, the California redistricting could nullify five new U.S. House seats Republicans are expected to gain from a new redistricting map in Texas.

Changes to California’s redistricting process would allow lawmakers to redraw congressional districts in ways that would heavily favor Democrats, regardless of redistricting efforts in Texas or other GOP-led states,

Democratic voters loathe partisan redistricting, but support California doing it to counter Texas, according to a new national poll on Gavin Newsom’s high-stakes gerrymander.

The Texas Senate gave final approval to a new, Republican-leaning congressional voting map early Saturday, sending it to Gov. Greg Abbott for his signature. President Donald Trump has pushed for the map to help the GOP maintain its slim majority in Congress in the 2026 midterm elections.
