Gerrymandering spreads in US states following Trump's call for new congressional districts

Efforts to redraw congressional voting districts, driven by former President Donald Trump, are gaining momentum nationwide as political parties seek advantages for next years elections. Trump aims to defy the historical pattern of the presidents party losing seats during midterms. In response, Republican state officials have redrawn House districts to boost GOP prospects, while Democrats have launched their own gerrymandering strategies.

Each seat in the House carries significant weight, as Democrats need just three additional seats to take control from Republicans and potentially obstruct Trumps legislative agenda. Mid-decade redistricting has so far created nine seats Republicans believe they can capture and six for Democrats, giving the GOP a nominal edge of three seats. However, legal challenges in several states make the outcome uncertain.

State-by-State Overview

Other States

Several other states are exploring or planning redistricting ahead of the 2026 elections. In some, proposed maps could favor Republicans or Democrats by one to two seats, while in others, no changes have yet been approved. Legal and legislative hurdles, including petitions, court challenges, and constitutional constraints, continue to complicate these efforts. Deadlines for candidate filings and legislative approvals add additional pressure, making the final outcome uncertain in many regions.

As the 2026 elections approach, the struggle over congressional districts highlights the high stakes of mid-decade redistricting and the increasingly contentious role of courts, legislatures, and voters in shaping electoral maps.
