Californians overwhelmingly backed Proposition 50, the crucial redistricting measure that Democrats have said is essential to safeguarding democracy and pushing back against the Trump administration.
“We stood firm in response to Donald Trump’s recklessness, and tonight, after poking the bear, this bear roared with unprecedented turnout in a special election with an extraordinary result,” Gavin Newsom said on Tuesday after the ballot measure passed.
The effort was a direct attempt to counteract Texas’s partisan gerrymander, undertaken at Trump’s behest, to create several new safely Republican districts. Under Prop 50, California will halt the work of its independent redistricting commission until after 2030 and allow the legislature to redraw congressional districts to carve out five additional Democratic seats.
The new map is expected to oust longtime Republican officials, and have significant effects on the 2026 midterms.
How did the state vote?
As of Wednesday morning, results showed that some 63.8% of voters approved the proposition with just 36.2% voting against the measure in what the Associated Press described as a “swift and decisive victory”. More than 8 million people voted in Tuesday’s election and the measure won the majority of votes along much of the coast and in southern California. It was largely unpopular in the northern and inland regions that will be most affected by redistricting.
Who is at risk of losing their seat?
These Republicans are at risk under California’s new congressional map: Darrell Issa, whose district covers east San Diego county; Doug LaMalfa, who has represented a large swath of rural northern California for more than a decade; Ken Calvert, a Riverside county representative who has served in the US House since 1993; David Valadao, who represents the southern San Joaquin valley; and Kevin Kiley, the representative for much of eastern California. Kiley introduced a bill to ban mid-decade redistricting nationwide, but his proposal did not advance.
After the measure passed, Republicans in California sued over Prop 50, and asked the court to block the new maps from taking effect. An attorney representing the plaintiffs – which include Republican state lawmaker David Tangipa, 18 California voters and the state’s Republican party – said that Democrats drew congressional boundaries to increase the voting power of Latinos. The new congressional districts will leave racial representation almost unchanged, according to an analysis by the Public Policy Institute of California.
How will Prop 50’s passage affect the midterms?
The measure is expected to have a major effect on the outcome of the 2026 midterms. Past elections have shown that the president’s party typically loses ground in midterm elections, and Democrats argued Prop 50 will help ensure Republicans do not retain full control of the federal government.
“The passage of this new map – which is designed to protect a slew of vulnerable Democrats and will cost Republicans three to five seats in 2026 – is the most consequential development to date in the mid-decade redistricting wars due to the sheer number of seats that it impacts,” Erin Covey, with the Cook Political Report, said in a statement.
“The outcome of these races in California could ultimately determine which party wins control of the House next November.”
What does this mean for Gavin Newsom?
The decisive victory of Prop 50 is a major win for the proposal’s biggest champion, Gavin Newsom. The California governor has been one of Trump’s most high-profile opponents and helped rally massive support for the proposal. Newsom is widely expected to seek the White House in 2028 and the win has further raised his profile nationally and elevated his status as a Democratic leader.
Bob Shrum, a veteran Democratic consultant who leads the Center for the Political Future at the University of Southern California, told the Guardian this week that Newsom had gambled on Prop 50 and it appeared it would pay off.
“But more than that is the fact that he fought back – that he dared to do this, that people said it was dangerous for him, and he forged ahead with it anyway.”
