California governor Gavin Newsom on Thursday signed a sweeping redistricting proposal aimed at redrawing the state’s congressional boundaries to create five new Democratic US House seats – a direct response to the gerrymandered maps Republicans in Texas are advancing at the behest of Donald Trump.
The Democratic-controlled state legislature voted to advance a legislative package revising California’s maps after hours of debate. With Newsom’s signature, the measure now heads to voters in a special election this November.
Newsom, who led the redistricting push, said California was “neutralizing” Texas’s maps designed to help Republicans stave off losses in next year’s congressional midterm elections.
“They fired the first shot in Texas,” the governor said, surrounded by Democratic lawmakers at a signing ceremony on Thursday afternoon. “When all things are equal, [when] we’re all playing by the same set of rules, there’s no question that the Republican party will be the minority party in the House of Representatives next year.”
The nation’s two most populous – and ideologically opposed – states were racing on parallel tracks toward consequential redistricting votes, potentially within hours of each other. As Democrats in Sacramento signed off on a legislative package that would put their “election rigging response act” before voters in a special election this fall, Republicans in Austin were nearing a final vote on their own partisan map.
“We will not let our political system be hijacked by authoritarianism. And today, we give every Californian the power to say no,” said assembly speaker Robert Rivas, a California Democrat, in remarks before the vote. “To say no to Donald Trump’s power grab and yes to our people, to our state and to our democracy.”
In California, Democratic state lawmakers faced a Friday deadline to give the secretary of state’s office enough time to place the amendment on the November ballot. Both chambers took up the package simultaneously on Thursday, volleying it back and forth until final approval was secured on all three measures: the proposed congressional map, an accompanying constitutional amendment and funding to run the administration of the special election.
Democrats broke into applause on the chamber floor after the assembly passed the constitutional amendment.
Approval by the Texas senate, which is expected as early as Thursday, would mark the end of a dramatic showdown with the state’s outnumbered Democratic lawmakers whose two-week boycott captured national attention and set in motion a coast-to-coast redistricting clash.
The California plan is designed to flip as many as five Republican-held seats in California – the exact number of additional GOP seats Trump has said he is “entitled to” in Texas.
“He’s trying to rig the election,” Newsom said of the president. “Open your eyes to what is going on in the United States of America in 2025.”
The redistricting tit-for-tat is an extraordinary deviation from the norm that will determine the battle lines for next year’s midterm elections. Traditionally, states redraw congressional maps once a decade based on census data, with both the Texas and California maps originally intended to last through 2030.
Before Thursday’s vote, California Republicans pleaded with their Democratic colleagues to oppose what they derisively called a “Gavinmander”. Some members disagreed with Trump’s push for partisan maps in Texas and elsewhere, but said Newsom’s “fight fire with fire” was harmful.
“The problem when you fight fire with fire is you burn it all down,” James Gallagher, the state assembly Republican leader, said at a news conference.
Initially, Democratic lawmakers said the changes would only take effect in response to a gerrymander by a Republican state – a condition that would be met when the Texas legislatures sends the maps to the state’s governor, Greg Abbott, for his promised signature. But they amended the language on Thursday to remove any reference to a trigger, arguing it was no longer necessary now Texas has moved ahead.
A Texas senate committee approved the GOP plan on Thursday morning, setting up a vote on final passage in the chamber, which was scheduled to reconvene that evening.
California was acting after a dramatic showdown in Austin, where Democratic lawmakers left the state earlier this month to delay a GOP redistricting plan pushed by the president. They returned only after California moved forward with its counterproposal. When they returned, some were assigned police minders and forced to sign permission slips before leaving the capitol. Several spent the night in the chamber in protest before Wednesday’s session, where Republicans pushed through a map designed explicitly to boost their party’s chances in 2026.
California Democrats are moving ahead after days of contentious debate over the cost – and consequences – of a referendum to temporarily toss out the maps drawn by the state’s voter-approved independent redistricting commission. Republicans estimated that a special election could cost more than $230m – money they said would be better spent on other issues such as healthcare.
On Wednesday night, the state supreme court declined an emergency request by Republican lawmakers seeking to block the Democratic plan from moving forward. Republicans have vowed to keep fighting it in court, and called for a federal inquiry into the proposal.
The redistricting push has also caused angst among some Democrats and independents who have fought for years to combat gerrymandering.
Testifying in favor of the changes during a hearing earlier this week, Sara Sadhwani, a political science professor who served as a Democratic member of the state’s independent redistricting commission in 2020, said the map-drawing tit-for-tat presented California voters with a “moral conflict”. But she argued that Democrats had to push back on the president’s power play.
“It brings me no joy to see the maps that we passed fairly by the commission to be tossed aside,” she said. “I do believe this is a necessary step in a much bigger battle to shore up free and fair elections in our nation.”
The California revision also drew the backing of former president Barack Obama and other champions of fair redistricting, such as his former attorney general, Eric Holder.
But Newsom’s redistricting plan – a high-stakes gambit for the term-limited governor who has made no secret of his 2028 presidential ambitions – is not assured to succeed. It faces mounting opposition from high-profile Republicans, including the state’s former governor Arnold Schwarzenegger, who has vowed to “terminate gerrymandering”.
Early polling has been mixed. But a new survey conducted by Newsom’s longtime pollster David Binder found strong support for the measure in the heavily Democratic state, with 57% of voters backing it while 35% opposed it.
“All of us support independent redistricting, here in California and in every state in this union,” said Mike McGuire, the senate president pro tempore, at the signing ceremony. “One thing that we do not support is unilateral disarmament, when the fairness of the 2026 election is being threatened.”
