The Verdict Is In On Republicans’ Redistricting Gambit

Now that the midterms are over, Republicans can take stock of just how their midterm redistricting push panned out by the numbers.  

The redistricting blitz kicked off with President Donald Trump’s aggressive 2025 push for Texas lawmakers to redraw the lines to gain the GOP five additional seats.

The Republican-led effort prompted other red states, including North Carolina and Ohio, to follow suit. The dominoes continued falling after the Supreme Court struck down race-based redistricting requirements, prompting Tennessee, Florida, Louisiana, and Alabama to move quickly to redraw their maps ahead of the November midterms.

But Tuesday’s results suggest Republicans are on track to lose nearly every seat they had hoped to gain through the redistricting push. Democrats cruised to victory, capturing control of both the House and Senate. CBS News estimates Democrats could ultimately hold between 251 and 268 House seats.

But those results do not necessarily mean Republican redistricting efforts cost the party seats, journalist Sean Trende argued in an analysis published Wednesday.

Trende examined how the election might have unfolded under old congressional maps, arguing that the results reflect a deeper Democratic wave than a referendum on redistricting.

Republicans failed to secure many of the gains they sought, but the new maps may not have left the party worse off than it would have been under the previous boundaries.

North Carolina offers the clearest potential example of a so-called “dummymander,” the term for a redistricting effort that backfires and costs the party seats. Republicans initially held a 10-4 advantage in the state’s congressional delegation and redrew the map for 2026 in hopes of expanding it to 11-3. Instead, Democratic Rep. Don Davis barely held his seat, while six Republicans fumbled under the new maps, producing a 10-4 Democratic advantage.

But Trende found that applying the statewide Democratic swing in the election to the previous map also would have produced a 10-4 Democratic delegation.

Texas tells a similar story. The party had hoped to gain five seats through its new map but won only one of the targeted districts, the 32nd. Democrats flipped the 15th and 23rd districts, leaving Republicans with a net loss.

Still, Trende argued that the two Republican incumbents who lost those districts likely would have been vulnerable under the previous map as well.

“The state was a disaster for Republicans, from the top of the ticket to the bottom,” Trende wrote. “The statewide ticket was wiped out, and the state House map failed spectacularly.”

In Florida, Alabama, and Tennessee, Trende found little evidence that redistricting left Republicans worse off.

Florida Democrats won districts Republicans had redrawn to improve their chances. But Trende argued that the new boundaries may have made the 13th and 15th districts more favorable to Republicans than they were under the previous map.

“In April 2026, Florida enacted a revised map to unwind an unconstitutional racial gerrymander. Last night, Florida voters likely elected 20 Republicans and 8 Democrats to the US House,” Florida Gov. Ron DeSantis said. “Had the old map been in effect, it would have been 18 Republicans and 10 Democrats.”

In Alabama, both Democratic incumbents in majority-black districts won re-election, leaving Republicans with the same five House seats they held before the election.

Tennessee presented a more complicated outcome. Republican Rep. Scott DesJarlais is on track to lose his seat in a shocking upset. He almost certainly would have won under the previous boundaries, according to Trende’s analysis. Republicans, however, picked up the newly created 9th District, which would’ve been far out of reach under the old lines. In short, Tennessee’s new map was roughly a wash for the GOP. 

Trende also examined California, where he said the Golden State was “likely to be a killing field for Republicans regardless of the remap.”  

Still, many conservative pundits argued the GOP’s aggressive redistricting push, coupled with the Supreme Court’s Voting Rights Act decision, boosted black and minority turnout across the American South. 

“Few things have inspired black voters to vote across the South more than Trump’s redistricting initiative to wipe out black voting districts,” Erick Erickson, a conservative commentator based in Georgia, said. “Even in states that didn’t do it, the threat of it mobilized black voters more than anything in recent decades. What Stacey Abrams could not do, Trump did.”

But on net, the math of the redistricting itself seems to have had minimal impact on the final seat count in the House, and certainly had no impact on who won the majority.
