For instance, Illinois Democrats have drawn maps that pack Republican voters into a handful of districts, allowing the party to hold a supermajority in the state’s congressional delegation despite competitive statewide races.
In Maryland, convoluted district shapes have helped Democrats secure seven of eight House seats in a state where Republicans routinely win about 40% of the vote.
New York Democrats attempted an aggressive gerrymander in 2022, only to have it struck down by courts, but the episode highlighted ongoing partisan map-drawing in left-wing strongholds.
Overall, both parties have a history of manipulating districts for gain, with gerrymandering often canceling out nationally but distorting representation at the state level.
In response to the Republican surge, California Democrats have placed Proposition 50 on the November 2025 ballot, a measure that would authorize temporary congressional map changes through 2030 to counter moves in Texas and other red states.
The proposition, backed by Gov. Gavin Newsom and the state Democratic Party, directs the independent Citizens Redistricting Commission to adopt legislatively influenced boundaries, potentially putting five Republican-held seats at risk in districts currently represented by figures like Reps. Kevin McCarthy and Mike Garcia.
With Republicans controlling more state legislatures than Democrats, the GOP appears positioned to net additional House seats through these maneuvers.
Democrats, who fell short in 2024, need to net just three seats to reclaim the House majority in 2026, making every district adjustment critical.
The Senate remains a tougher climb for Democrats, who must defend incumbents in red-leaning states while targeting GOP vulnerabilities.
U.S. Rep. Don Davis, a North Carolina Democrat, blasted the plan as “beyond the pale” in a statement, accusing Republicans of undermining fair elections as his 1st District faces elimination under the new map.
Trump, however, hailed the North Carolina map on social media, calling it a win for “putting America First.” State House Speaker Destin Hall echoed the sentiment by reposting Trump’s message, adding, “We’re putting America First in NC!”
As legal challenges mount and the redistricting arms race intensifies, the 2026 midterms could hinge on these behind-the-scenes battles over district lines, testing the resilience of America’s electoral system.
