Texas mid-decade redistricting (2003)
Then-U.S. House Majority Leader Tom DeLay engineered a mid-decade redrawing of Texas's congressional districts after Republicans took full control of state government. Democratic state senators fled to New Mexico to break quorum before the map ultimately passed, shifting six U.S. House seats to Republicans.
Republicans gained six Texas U.S. House seats in the 2004 elections, helping cement their national House majority.
In LULAC v. Perry (2006), the Supreme Court upheld most of the map but struck down one district as a Voting Rights Act violation, establishing that mid-decade redistricting was constitutionally permissible.
The 2003 episode is the direct precedent for the 2025 redraw and established the legal baseline that Texas now relies on. The 2026 litigation will test how far that baseline stretches when racial-gerrymandering claims are central.
