Supreme Court clears GOP-drawn map for 2026 midterms while gerrymandering challenges continue

April 27th, 2026: Supreme Court reinstates the Texas map

Overview

States usually redraw congressional districts once a decade, after the census. Texas just redrew its map four years early—and the U.S. Supreme Court has now cleared it for the 2026 midterm elections.

The high court's order, issued without a written opinion, lifts a federal three-judge panel's November injunction that had found the map likely engaged in intentional racial gerrymandering. The new boundaries could shift up to five U.S. House seats from Democrats to Republicans, a swing large enough to determine majority control of a chamber where Republicans currently hold a slim margin. Underlying lawsuits brought under the Voting Rights Act and the 14th and 15th Amendments continue in lower courts, but they will not stop the map from being used in November.

Why it matters

Five U.S. House seats could flip parties under maps a federal court found likely racially gerrymandered—enough to decide control of Congress in 2026.

Republicans gain House seats in Texas, hold majority in 2026

With the map in place for the November election, Republicans win three to five additional U.S. House seats from Texas, offsetting Democratic gains in California and giving the GOP a slightly larger or similar majority in the next Congress. This is the most direct and widely projected near-term outcome of the Supreme Court order.

Supreme Court strikes down map after 2026, ordering new lines for 2028

The underlying lawsuits proceed to a full merits ruling. A district court reaffirms its finding of intentional racial gerrymandering, and the Supreme Court—on a fuller record—agrees in part, requiring Texas to redraw at least some districts before 2028. Republicans keep the seats won under the current map for one cycle but lose the structural advantage going forward.

Court upholds Texas map on the merits, narrowing racial-gerrymandering doctrine

After full briefing, the Supreme Court rules that Texas's use of race in drawing districts was either justified by Voting Rights Act compliance or insufficiently proven, locking in the map through 2030 and making future racial-gerrymandering challenges harder to win. This would mark a significant doctrinal shift extending recent rulings narrowing voting-rights remedies.

Mid-decade redistricting becomes the new normal

Other states follow the Texas and California examples, redrawing maps whenever one party controls the levers of state government. Redistricting becomes a continuous political weapon rather than a once-a-decade event, with courts routinely reviewing new maps in the run-up to each federal election.

Historical Context

Texas mid-decade redistricting (2003)

2003

What Happened

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.

Outcome

Short Term

Republicans gained six Texas U.S. House seats in the 2004 elections, helping cement their national House majority.

Long Term

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.

Why It's Relevant Today

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.

Shelby County v. Holder (2013)

June 2013

What Happened

The Supreme Court struck down the formula in Section 4 of the Voting Rights Act that determined which jurisdictions—including Texas—needed federal preclearance before changing voting rules or maps. The 5-4 ruling effectively ended preclearance.

Outcome

Short Term

Texas implemented voter-ID laws and redistricting changes that had previously been blocked or modified under preclearance review.

Long Term

Voting-rights challenges shifted from pre-implementation federal review to slower, after-the-fact litigation in federal court—the procedural posture in which the 2025 Texas map is now being fought.

Why It's Relevant Today

Without preclearance, Texas could enact its 2025 map without federal sign-off, leaving challengers to pursue injunctions and appeals—precisely the path the Supreme Court has now narrowed by lifting the lower court's stay.

Rucho v. Common Cause (2019)

June 2019

What Happened

The Supreme Court ruled 5-4 that partisan gerrymandering claims are 'political questions' beyond the reach of federal courts, even when maps were drawn for explicit partisan advantage. Racial-gerrymandering claims, however, remained justiciable.

Outcome

Short Term

Federal courts could no longer strike down maps purely for partisan bias; plaintiffs had to frame challenges around race or other constitutional violations.

Long Term

Litigation strategy in redistricting cases pivoted toward racial-gerrymandering and Voting Rights Act theories, including in the current Texas case.

Why It's Relevant Today

Rucho explains why challengers must prove the Texas map sorted voters by race, not just by party—the very theory the lower court accepted and the Supreme Court has now temporarily set aside.
