GOP Redistricting Sweep 2026: How Callais Is Building a Structural House Majority Before a Single Vote Is Cast

# GOP Redistricting Sweep 2026: How Callais Is Building a Structural House Majority Before a Single Vote Is Cast

> **Quick answer:** Thirteen days after the Supreme Court's April 29 *Callais* ruling gutted the Voting Rights Act, at least four states — Tennessee, Alabama, Virginia, and Louisiana — are actively redrawing congressional maps that could hand Republicans up to 19 net House seats before a single 2026 ballot is cast. Tennessee's new map is already signed into law. Virginia's voter-approved Democratic map has been thrown out. Alabama and Louisiana are in legislative and court-driven map processes with live primaries suspended. Democrats filed a SCOTUS emergency petition on May 11, but legal experts give it little chance of success.

When political analysts describe a "structural majority," they mean something precise: a House advantage built into the geography of districts before voters ever weigh in. The *Callais* redistricting wave is producing exactly that for Republicans — not through winning more voters, but through redrawing the lines that contain them.

Here is the full seat math, state by state, and what it means for the 2026 House.
