After the Supreme Court’s conservative majority allowed Texas lawmakers’ new congressional map to proceed, Republicans head into the 2026 election year with an advantage in the redistricting fight President Trump helped ignite. The court’s decision came despite a lower court finding that the Texas legislature had likely conducted a racial gerrymander. The map could net Republicans about five additional seats.
This is the latest turn in a nationwide redistricting scramble — from California to Florida — that Trump pushed to help preserve Republican control of the House. If Democrats capture the chamber, they could block the president’s legislative agenda and open investigations into his administration. The House is narrowly divided: 220 Republicans to 213 Democrats, and historically the president’s party tends to lose seats in midterms.
Analysts estimate the map changes so far could tilt roughly 12–14 seats toward Republicans, with Democrats able to push about nine seats their way via countermeasures. Much depends on pending court challenges and state legislative votes, so outcomes remain uncertain.
Trump’s push began in Texas and prompted dramatic responses. After he called on Texas to shift five seats toward the GOP, Democrats staged a more-than-two-week walkout this summer to delay maps they said would dilute Black and Latino voting power. California Democrats countered by approving a map in a special election that could flip five Republican-held seats there.
Republicans in Missouri and North Carolina adopted plans targeting Democratic-held districts. In Indiana, the state House passed a map that could help the GOP gain two seats; it now moves to the Senate, where Republicans are split. Some Indiana Republicans have balked at following Trump’s direction, drawing threats from party leaders of primary challenges; several lawmakers also reported anonymous threats to their families.
Republicans generally have more redistricting options. State legislatures redraw maps and Republicans control more legislatures nationwide. Some Democratic-governed states have legal limits on partisan gerrymandering or require independent commissions to draw lines, constraining Democratic opportunities.
A few 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 needed to schedule the election in time. If approved, the change could shift two or three seats toward Democrats. Maryland’s Democratic governor formed a commission to recommend redistricting changes, though Maryland has only one Republican-held House seat to target.
In Florida, Republican Gov. Ron DeSantis is urging the GOP-led legislature to redistrict this spring to gain as many as five seats. The Florida House held its first mid-decade redistricting committee meeting recently. Florida’s laws ban partisan gerrymandering and federal bans on racial gerrymandering under the Voting Rights Act (VRA) could also limit map changes, but the Supreme Court is currently considering aspects of the VRA that, if weakened, might allow more aggressive redistricting beneficial to Republicans.
The Voting Rights Act prohibits intentional efforts to weaken minority voting power by “cracking” (splitting groups across districts) or “packing” (concentrating them into a single district). How courts interpret and enforce those protections will influence how far states can go in reshaping congressional maps ahead of the 2026 elections.
