Efforts to redraw U.S. House districts for partisan advantage are spreading throughout the country as states brace for the 2026 elections. Following the push from former President Trump for mid-decade redistricting, lawmakers in several states have begun to approve new congressional maps aimed at gaining or maintaining party control.

In Texas, the Republican-led legislature adopted a controversial map designed to enhance GOP prospects. Democrats in California, prompting by the need to remain competitive, have countered with their own redistricting plans, although these require voter approval to take effect. Missouri has also entered the fray, where lawmakers recently revised maps which could potentially allow Republicans to capture an additional congressional seat.

Redistricting traditionally occurs post-census every decade; however, several states currently allow for mid-cycle adjustments with no legal barriers in place. This trend is underscored by the U.S. Supreme Court's stance that political gerrymandering is permissible under federal law.

As it stands, Democrats only need to gain three additional seats in the House to take control. Historically, it is common for the party in the White House to lose seats during midterm elections, adding urgency to the strategic reconfigurations happening in state legislatures.

Here is a closer look at the actions taking place across key states:

Missouri's Plan

The Missouri legislature recently crafted a congressional map aimed at securing a better chance for Republicans to win in seven out of eight districts, up from a current six. The plan has met opposition, as detractors are mobilizing to challenge it through referendums and lawsuits.

Texas's Republican Gains

In Texas, prompt action by Republican lawmakers followed a Democratic boycott intended to derail redistricting efforts. Republicans successfully adopted a revised map aiming to increase party control in the House.

California's Response

California Democrats, holding a significant majority already, are aggressively pursuing their own redistricting initiatives to potentially add to their congressional strength. They face hurdles, however, requiring voter participation for any amendments made to existing maps.

Other States in Play

Indiana's governor has indicated that a redistricting session is likely, while Kansas is also gearing up to discuss congressional maps. Florida's governor has expressed interest in joining the initiative for new congressional financing, asserting that a new census should reflect the state's population growth and warrant another congressional seat.

Utah lawmakers are currently soliciting public comments on their proposed congressional maps, with plans to finalize and submit them for judicial review soon. In contrast, Ohio faces a mandate to redraw its congressional districts due to insufficient bipartisan support in their previous map, with Republican leaders preparing to act in November.

Looking Forward

As these developments unfold, the partisan landscape will continue to become increasingly contentious. The actions being taken now will undeniably influence the upcoming elections and the balance of power within the House.
