Republicans spent more than a year redrawing dozens of U.S. House districts at Donald Trump's urging, betting the maps would lock in their narrow majority ahead of the November 2026 midterms. Instead, Trump's record-low approval rating amid the Iran war and high gas prices has undercut most of those gains, according to an analysis of the 2026 House map.
As of June 2026, Republicans had increased their advantage in 16 redrawn districts, but nine Republican-leaning districts are now rated as Democratic-leaning or too close to call, according to a Reuters analysis authored by Joseph Ax. Of nine Texas and Florida targets that analysts had considered highly competitive pickups, only one is now seen as a safe Republican win, the outlet reports.
Latino Voter Shifts Challenge GOP Redistricting Gains
Texas Republicans redrew the state's U.S. House map last summer with Trump's backing, part of a redistricting process that typically happens only once a decade after the census. Democrats, meanwhile, gained an edge in six districts through the broader national remapping fight. The new Texas and Florida maps reshaped nine Democratic-held seats into districts Trump carried in 2024 by 9 to 20 percentage points, according to the same Reuters report.
Erin Covey told the outlet that the Texas and Florida maps overestimated continued Hispanic support for Republicans and said the party might fail to flip any of the four Florida seats it redrew. In the median outcome, Covey projects Republicans will gain only around three House seats from redistricting overall, while a strong Democratic wave could flip that math entirely, netting Democrats two seats instead. Jacob Rubashkin, an analyst with Inside Elections, said the national House map is now better for Republicans than it was before redistricting began, but added that Republican pickups are expected to fall well below original expectations even though the party will still benefit compared with having never redrawn the lines at all.
National reporting has tied that overestimation to a broader shift: declining Latino support for Republicans, driven by rising living costs, healthcare funding cuts, and mass deportation policies, has jeopardized GOP redistricting targets across Texas and Florida, according to CNN. Republicans had drawn their Sunbelt boundaries assuming the rightward shift among Hispanic voters seen in 2024 would persist.
Money Pours Into the Most Contested Redrawn Seats
The financial stakes in these remapped districts have been enormous. Republican-aligned groups spent more than $12 million on average in four of the six highest outside-spending House races, and all four of those contests are in Republican-redistricted seats, per Reuters. Democrats need to flip at least four House seats on November 3 to win control of the chamber.
The U.S. Supreme Court issued a 6-3 ruling in Louisiana v. Callais in April, in a case about Voting Rights Act protections for districts with large minority populations, according to the Legal Defense Fund. That ruling reversed lower-court mandates requiring Louisiana to maintain two majority-Black congressional districts, and it opened the door for Alabama Republicans to dismantle one of the state's two predominantly Black districts and create a majority-white one instead.
Alabama and California Show the Map's Two Faces
Democratic Rep. Shomari Figures could prevail in Alabama's redrawn district during a strong Democratic wave. Separately, the U.S. Supreme Court permitted Alabama to use its 2023 Republican-drawn congressional map for the 2026 midterms, which dropped the Black voting-age population in the 2nd Congressional District from 48% to 40%, as PBS News reported, making the seat Figures first won in 2024 under court-mandated boundaries considerably more vulnerable.
California moved in the opposite direction. State Democratic lawmakers passed a new map targeting five Republican-held seats after voters approved Proposition 50 in November 2025 with 64.4% support, temporarily suspending the state's independent redistricting commission through 2030, according to the California Secretary of State.
A Tejano Star Tests the Limits of a Redrawn Texas District
Nowhere is the gap between the map on paper and the map in practice clearer than in Texas's 15th Congressional District. Monica de la Cruz's district remained solidly Republican under the updated map, with Trump winning nearly 18 percentage points there in 2024.
Her opponent, Tejano music star Bobby Pulido, has sought to turn his cultural popularity into political success, and the race is now widely seen as a tossup, per the Reuters analysis. Pulido, who traded his final concert for a shot at Congress, is challenging de la Cruz.
Courts Push Back on Off-Cycle Maps
The redistricting fight has also run into judicial resistance elsewhere. In May, the Virginia Supreme Court struck down a voter-approved Democratic redistricting amendment in a 4-3 decision, ruling the legislature had violated procedural rules and blocking a map that could have flipped up to four Republican-held House seats.
In Congress, the bipartisan House Problem Solvers Caucus introduced four bills in September, including the TRUST Act and MAPS Act, aimed at banning mid-decade redistricting nationwide and setting uniform map-drawing standards. The legislation, unveiled by caucus co-chairs Brian Fitzpatrick and Tom Suozzi, reflects growing institutional unease with the off-cycle map wars that have now touched nearly 145 million Americans — roughly 40% of the U.S. population — who live in states where congressional lines were redrawn between the 2024 and 2026 elections, according to AP News.
Michael Li said trying to predict the future through redistricting can be too clever for one's own good, a line that captures the central tension running through this cycle. An analysis published in July by Sabato's Crystal Ball found that despite all the mid-decade redraws, the overall 2026 House map is no more favorable to Republicans than the 2018 midterm map was, with the median House district shifting roughly two percentage points toward Republicans relative to 2024. Trump campaigned last Saturday at Truist Arena in Highland Heights, Kentucky, stumping for Ed Gallrein and Andy Barr, even as the maps his own party engineered struggle to deliver the majority they were built to protect.
