The Supreme Court’s conservative majority allowed Texas lawmakers’ new congressional map to stand, giving Republicans an advantage as they head into the 2026 redistricting fight that former President Trump helped spark. The high court approved the map even after a lower court concluded the Texas legislature had likely engaged in a racial gerrymander. Analysts say the map could yield roughly five additional Republican seats in Texas.
This development is part of a broader, nationwide scramble over maps—from California to Florida—that Republican strategists, including Trump, have pushed to help preserve GOP control of the House. Control of the chamber matters to both parties: a Democratic House could obstruct the president’s agenda and open investigations into his administration. The current House is narrowly divided, with 220 Republicans and 213 Democrats, and historically the president’s party tends to lose seats in midterm elections.
Across states, analysts estimate recent map changes could tilt about 12–14 seats toward Republicans overall, while Democrats could recover roughly nine seats through countermeasures. Much depends on remaining court challenges and upcoming state legislative votes, so final outcomes are still uncertain.
Trump’s campaign to reshape maps began in Texas and provoked dramatic reactions. After he publicly urged Texas to shift five seats to the GOP, Democrats staged a more-than-two-week walkout this summer to delay maps they said would dilute Black and Latino voting power. In California, Democrats approved a special-election map that could flip five Republican-held seats there.
Republicans in states such as Missouri and North Carolina have adopted plans targeting Democratic-held districts. In Indiana, the state House passed a map that could help the GOP gain two seats; the proposal now goes to the state Senate, where Republicans are split. Some Indiana Republicans have resisted following Trump’s direction, prompting party leaders to threaten primary challenges and leading several lawmakers to report anonymous threats against their families.
Republicans generally start with more redistricting options because state legislatures—where maps are typically drawn—are controlled by GOP majorities in more states. By contrast, some Democratic-led states have legal limits on partisan gerrymandering or use independent commissions to draw lines, which constrains Democratic opportunities to redraw maps aggressively.
A handful of states remain key battlegrounds. Virginia’s Democratic-led legislature voted to hold a special election to amend the state constitution to permit redistricting; a follow-up vote in January is required to schedule that election in time. If the amendment clears voters, it could shift two or three seats toward Democrats. In Maryland, the Democratic governor has formed a commission to recommend changes, though Maryland has only one Republican-held House seat that Democrats could realistically target.
In Florida, Republican Gov. Ron DeSantis is pushing the GOP-led legislature to pursue mid-decade redistricting this spring with the aim of winning as many as five additional seats. The Florida House recently held its first mid-decade redistricting committee meeting. Florida law bars partisan gerrymandering and federal limits under the Voting Rights Act (VRA) prohibit racial gerrymanders, which could constrain major map changes. However, the Supreme Court is weighing elements of the VRA; if those protections are narrowed, states might have more latitude to draw maps favoring one party.
The Voting Rights Act bans intentional efforts to dilute minority voting strength by “cracking” (splitting a racial group across multiple districts to prevent them from forming a majority) or “packing” (concentrating a group into one district to reduce its influence elsewhere). How courts interpret and enforce those protections in upcoming rulings will shape how far states can go in redrawing congressional maps ahead of the 2026 elections.
