California voters back Democratic redistricting plan to counter Republican gains
California voters approved Proposition 50 on Tuesday, a ballot measure designed to redraw congressional districts in favor of Democrats, according to CBS projections with over 70% of votes counted. The move marks a direct response to Republican-led redistricting efforts across multiple states, intensifying a nationwide struggle for control of the U.S. House of Representatives ahead of the 2026 midterm elections.
Strategic shift in the battle for House control
The measure aims to reconfigure California's voting maps to potentially shift five House seats from Republican to Democratic control. Currently, Republicans hold a narrow five-seat majority in the 435-member chamber. A Democratic victory in 2026 could obstruct President Donald Trump's legislative agenda and empower congressional oversight, including investigations and potential impeachment proceedings.
However, the outcome remains uncertain. While California's initiative may bolster Democratic prospects, four Republican-led states-Texas, North Carolina, Missouri, and Ohio-have already redrawn their districts this year, creating a likely advantage in nine new seats. Utah also passed a new map favoring Democrats in one district, though it faces legal challenges.
Historical trends and political risks
Midterm elections, held halfway through a president's term, historically favor the opposition party. Research by the Brookings Institution shows the president's party lost House seats in 20 of the last 22 midterms since 1938. Galen Sheely, research director for the State Voting Laws Roundup project, noted that while Republicans face an "uphill battle," unpredictable political shifts could still alter the landscape.
"There are a lot of unknowns still, and a lot can happen before the midterms politically. But looking at it historically-this is an uphill battle for Republicans."

Unprecedented mid-decade redistricting sparks concern
Traditionally conducted once a decade after the U.S. Census, the current wave of mid-decade redistricting represents "a new strategy pushing boundaries that haven't been pushed before," Sheely said. The tactic began with Trump urging conservative states to redraw districts to maintain Republican control. Over a dozen states are now considering similar moves, raising alarms about the long-term health of U.S. democracy.
"Regardless of whether it's Democrats or Republicans, this is just not good for our republic in the long term. The question now is: where does this stop? It's political sabotage to our democracy."
Erik Nisbet, Northwestern University professor
Critics warn the practice could deepen polarization, erode trust in government, and eliminate competitive "battleground" districts-key to bipartisan compromise. Nisbet pointed to the ongoing government shutdown as evidence of worsening gridlock, which could embolden presidents to bypass Congress altogether.
Trump's role and Democratic pushback
President Trump justified the redistricting push by citing his 2024 electoral victories in states like Texas, which adjusted its maps to favor Republicans in five additional seats. In response, California Governor Gavin Newsom, a vocal Trump critic with reported presidential ambitions, championed Proposition 50, framing it as a necessary countermeasure.
"These folks don't play by the rules. If they can't win playing the game with the existing set of rules, they'll change the rules. That's what Donald Trump has done."
Gavin Newsom, California Governor
High-profile Democrats, including former President Barack Obama, Rep. Alexandria Ocasio-Cortez, and Vice President Kamala Harris, rallied support for the measure. Campaigns for and against Proposition 50 raised a combined $200 million, with Democrats significantly outspending Republicans. Newsom recently declared fundraising efforts complete.
Legal and procedural hurdles
California's redistricting process differed from Republican-led states. Due to a state law aimed at curbing gerrymandering, an independent commission typically redraws districts every decade. To bypass this, California held a costly special election-exclusively for Proposition 50-at a taxpayer expense exceeding $200 million. The new maps will expire in 2030, when the commission resumes control.
Meanwhile, the U.S. Supreme Court is reviewing a case that could further reshape redistricting rules nationwide, adding another layer of uncertainty to the 2026 midterms.
Broader implications for U.S. democracy
Analysts caution that the escalating redistricting war risks undermining public faith in elections. Nisbet emphasized that competitive districts, now disappearing, historically fostered negotiation and moderation in Congress. Without them, he warned, "the ripple effect will mean emboldening this president and future presidents to act unilaterally without Congress."
As both parties dig in, the 2026 midterms may hinge not only on voter sentiment but on the lasting consequences of these partisan map changes.
