Nine U.S. States Implement Mid-Decade Congressional Redistricting

Nine U.S. states have implemented new congressional district boundaries for the 2026 midterm elections, reassigning more than 34 million people—roughly one in 10 Americans—to new districts. The mid-decade redistricting battle began when Donald Trump requested that Texas redraw boundaries in five targeted districts, which prompted California to redraw five districts to favor Democrats.

Across the affected states, 15 districts were redrawn to potentially favor Republicans and six to favor Democrats, resulting in a net gain of nine districts for Republicans in the U.S. House of Representatives. Significant voter reassignments occurred in Texas, Louisiana, Tennessee, and Florida. In Utah, state judges ordered new boundaries after ruling that Republicans violated anti-gerrymandering laws, affecting over 69% of the state's voters.

Concurrent with these boundary changes, Republicans in Texas face accusations of further altering electoral rules. In Tarrant County, officials reduced election-day polling places by nearly 30 percent, a move currently being challenged in court. Critics argue these measures, alongside last year's redistricting, are designed to secure a Republican advantage, though some suggest the actions may instead galvanize Democratic opposition.
