How San Diego County Voted On Proposition 50

SAN DIEGO, CA — A majority of San Diego County voters joined the rest of California on Tuesday to approve Proposition 50, the statewide congressional redistricting measure.

With 803,151 counted in the county, 487,173 ballots, or 60.7%, were cast in favor of the measure, compared to 315,443, or 39.3%, against, according to unofficial election night results from the San Diego County Registrar of Voters. There were 270,000 projected outstanding ballots.

Election results will change, however, throughout the ballot-counting canvass period as vote-by-mail ballots, provisional ballots, and other ballots are tallied. The next release of unofficial results will be posted by 6 p.m. on Thursday, according to the Registrar of Voters.

The county election results are similar to the statewide tally for Proposition 50.

As of 4:20 a.m. Wednesday, 63.8% of statewide ballots cast were in favor of Proposition 50, compared to 36.2% against, according to the Secretary of State's Office.

Proposition 50 will establish new congressional district maps for the 2026, 2028 and 2030 elections. Democrats currently hold a 43-9 advantage in the state's U.S. House delegation, but Proposition 50 is expected to shake up five of the nine Republican-held congressional districts.

The GOP congressmen in those at-risk areas — Reps. Ken Calvert (Corona), Darrell Issa (Vista), Kevin Kiley (Rocklin), David Valadao (Bakersfield) and Doug LaMalfa (Richvale) — will see right-leaning voters reduced and left-leaning voters boosted in their respective districts in a shift that would make it likely a Democratic candidate would prevail in each race.

Issa, who unsuccessfully sued to block the new congressional maps from being implemented, called Proposition 50 "the worst gerrymander in history."

"I'm not going anywhere," he said in a defiant statement. "I'll continue to represent the people of California -- regardless of their party or where they live."

The 48th Congressional District that Issa, R-Bonsall, represents would lose parts of San Diego County and add more of Riverside County.

Supporters called Proposition 50 a way to check President Donald Trump and increase Democrats' chances of regaining control of the House of Representatives.

"Californians made their voices heard -- we will not let Donald Trump and his allies rig our democracy or silence our votes," San Diego City Councilmember Marni von Wilpert, a Democrat challenging Issa, said in a statement issued Tuesday night.

"Proposition 50 protects our voice at the ballot box and gives us a real chance to take our country back, starting right here in Southern California."

The measure, otherwise known as Congressional Redistricting or the Election Rigging Response Act, was spearheaded by Gov. Gavin Newsom. In August, he signed the legislative package that gave Californians a voice as to whether they wanted to push back against what Democrats characterize as Trump's power grab in Texas and other Republican-led states.

With the 2026 midterm elections just a year away, the redrawing of congressional maps to favor Republicans is a Trump strategy to maintain GOP control of the U.S. House of Representatives.
The president publicly instigated the gerrymandering, but Democrats in California and other states have seen an opportunity to counterpunch.

Newsom gave a live speech late Tuesday night on X, thanking voters and rallying Democratic leaders and voters nationwide ahead of the 2026 midterm battle.

"And let me make this crystal clear. We can de facto end Donald Trump's presidency as we know it the minute Speaker [Hakeem] Jeffries gets sworn in as Speaker of the House of Representatives," Newsom said. "It is all on the line, a bright line in 2026. And so I want to thank everybody that stood up not just for our democracy, for those that feel bullied and intimidated, stood up for this notion of co-equal branches of government and a system of checks and balances."
