Texas Republicans have released their highly anticipated plan for how to tip the balance in their favor in next year’s midterms – redrawing the state’s congressional map in favor of more GOP seats.

Multiple Democratic sources said the new map shows that Republicans are attempting to gain five more congressional seats, which they hope will help their chances of holding onto the House majority in the 2026 midterms. Democrats plan to challenge the map in court.

It’s a potentially seismic moment for the House, with Democratic governors in states like California vowing to attempt the same tactics to help their party win more seats if Republicans did indeed do this in Texas – leading to what one House Democratic lawmaker described to CNN as a “redistricting arms race.”

The map – which was a top priority for President Donald Trump – targets multiple Democrats, including Rep. Greg Casar, whose Austin-area seat is completely eliminated. That would likely force him into a primary with another longtime liberal Democrat, Rep. Lloyd Doggett, in the Austin area.

Casar vowed to “fight back with everything we’ve got.”
