Here are 4 key takeaways from California’s Prop. 50 election results
California voters approved Gov. Gavin Newsom’s effort to redraw the Golden State’s congressional maps that are poised to give Democrats five more seats in the U.S. House of Representatives, according to early election results.
Democrats framed Proposition 50 as a way to fight back against President Donald Trump, who earlier this year asked Republicans in Texas to gerrymander their districts to give the GOP an advantage in the 2026 midterms.
The initiative will temporarily replace the congressional maps drawn by the California Citizens Redistricting Commission, which voters created and expanded in 2008 and 2010 via a statewide ballot initiative, with new districts that favor Democrats.
We asked experts to weigh in on the implications of Tuesday’s election results beyond just which elected officials are sent to represent California in Congress in 2027. Here are four key takeaways from the Prop. 50 election results.
The ‘yes’ campaign benefitted from making Prop. 50 about Trump
If Tuesday’s results demonstrated anything, it’s how much California voters dislike the president.
“It is a testament to the polarizing nature of Donald Trump that California voters, who twice approved a commission to draw district lines, would be willing to let Democrats do a partisan gerrymander,” said UCLA election law professor Richard Hasen.
Carving out five more seats for Democrats is not something California voters would have approved, Hasen said, without Trump pressuring Texas leaders to gerrymander five more Republican districts in Congress.
Democratic leaders in California who strongly supported the Citizens Redistricting Commission faced challenges around messaging support for Prop. 50, said Thad Kousser, a UCSD political science professor. The ballot initiative went in direct opposition to the commission’s efforts to draw fair political maps.
Kousser said trying to explain to voters why they should vote to U-turn on redistricting was, “a complex message and a challenging political task,” for Prop. 50 supporters.
Instead, supporters of the measure were able to turn the ballot initiative into a proxy vote for Trump 10 months into his presidency, Kousser said.
“The success of Prop. 50 came down to the ‘yes’ campaign making this a referendum on Trump’s presidency, rather than a conceptual battle about who should be doing redistricting and how lines should be drawn,” he said.
Newsom took a big risk with Prop. 50. It paid off
Despite the lackluster initial public support for Prop. 50, Newsom hitched his not-yet-launched presidential ambitions to the measure, Kousser said.
Early polling showed that the gerrymandering initiative had less than 50% support from likely voters who were asked if they would vote “yes” on Prop. 50. One in five likely voters were undecided on the measure.
Additionally, the statewide initiatives in California typically fail about two-thirds of the time, according to the California Secretary of State’s Office.
That risk has paid off. Tuesday’s results are a major boost to the governor’s undeclared campaign, Kousser added. Newsom recently said he would consider running for president after the 2026 midterms.
“It solidifies his national reputation as someone who can fight Donald Trump effectively,” Kousser said.
Had Republicans spent more, results might have turned out differently
For much of the Prop. 50 campaign, the “yes” side had the lead, but support for the measure lingered close to 50%, said Dan Schnur, a politics and communications professor at UC Berkeley and USC.
That exhibited vulnerability, he said.
But between August and October, support for the measure grew. In August, 20% of likely voters reported that they were undecided about their voting preferences when asked by the UC Berkeley Institute of Governmental Studies. Notably, Schnur pointed out, the percentage of undecided voters dropped to 2% by late October.
Schnur said the historically late-deciding voters tend to vote no. Spending by Newsom and other Prop. 50 supporters meant that by Election Day, there were few undecided voters, he added.
“Even an incredibly disengaged voter would have to work very hard to avoid the messaging from the ‘yes’ side who pushed an anti-Trump message,” he said.
The two major “no” campaigns were led by Republican megadonor Charles Munger Jr. and former House Speaker Kevin McCarthy, who collectively raised about $44 million — less than half what Newsom’s campaign raised: $114 million.
After the “no” side ran out of money, the campaign against Prop. 50 fell silent.
“Once the dust is settled, it’s worth thinking that Republicans might have won this race after all,” Schnur said.
Rather than dumping money into the gerrymandering measure, Schnur said he suspected that national GOP donors preferred to use the money in future competitive House races elsewhere.
Even it isn’t right, California voters are aware of the ‘state of the game’
California voters are pretty savvy when it comes to propositions, and “we routinely reject propositions that we don’t feel like are in our best interest,” said Matthew Lesenyie, an assistant professor of political science at Long Beach State University.
Even when ballot initiatives are extremely well funded, money can’t always buy a race. Lesenyie pointed to Proposition 26, which appeared on Californians’ 2022 ballots, related to in-person sports betting at tribal casinos that voters overwhelmingly rejected.
In the case of Prop. 50, Lesenyie said Golden State voters understand that other states haven’t followed California’s lead in redistricting. What’s more, Texas’ leaders aren’t even giving their voters the option to weigh in on new maps, he said.
“It’s an acknowledgement that that’s the current state of the game, even if that doesn’t seem right,” he said.
An important thing to note about Prop. 50, he mentioned, was that the ballot initiative isn’t redrawing all of California’s political maps. The districts for California’s legislature will remain untouched by the measure.
“We’re going to keep fairness for representatives in the state, but we’re going to make a challenge for national majority political power in Congress, because that’s kind of all that matters, right now,” Lesenyie said.
