Updated vote tallies from the June 2 California statewide direct primary show incumbent candidates still holding decisive advantages in Santa Clara County races, with results from the county registrar’s office as of 5pm June 8 continuing to reflect strong performances across the board.
Reported turnout numbers have risen substantially as mail-in ballots have been counted, climbing from an election-night estimate of roughly 19% to 38.63% as of the morning of June 9.
In the race for Santa Clara County District 1 Supervisor, incumbent Sylvia Arenas has surpassed the majority threshold needed to win the nonpartisan seat outright. With 49,069 votes, or 63.55%, Arenas has secured more than a majority against challenger Rebecca Munson, who received 28,082 votes, or 36.37 percent.
Because the race is a nonpartisan contest in which a candidate receiving a majority wins outright, Arenas is on track to retain her seat without proceeding to a November runoff, pending final certification of results.
Arenas, first elected to the position in 2022, has pointed throughout the campaign to what she describes as a sweeping expansion of county services in South County as an argument to retain her seat.
Munson, a Morgan Hill Unified School District trustee and first-time candidate for county office, challenged Arenas on fiscal oversight and responsiveness, arguing that South County communities needed a stronger advocate at the county level.
In the race for U.S. Representative for Congressional District 18, incumbent Democrat Zoe Lofgren leads the four-candidate field with 34,055 votes, or 59 percent. Republican Shane Lewis is in second place with 15,715 votes, or 27.23 percent. As a top-two primary, both candidates will advance to the November general election.
Democrat Luis Arreguin received 10.78% of the vote, while independent Chris Demers of Gilroy trailed with 2.97 percent.
Lofgren, who has represented parts of the South Valley in Congress since 1995, has cited federal infrastructure investment in the region, including funding for flood protection along Coyote Creek and seismic retrofitting of Anderson Dam, as central accomplishments of her tenure.
Lewis, an R&D electrical test engineer and former U.S. Marine, and Arreguin, who has a background in education and community advocacy, both challenged the incumbent’s record.
In the State Assembly District 28 race, incumbent Democrat Gail Pellerin has received 60,153 votes, or 67.52%, with Republican challenger Carol Pefley receiving 28,925 votes, or 32.47 percent. As the only two candidates in a top-two primary, both will advance to the Nov. 3 general election.
District Attorney Jeff Rosen leads challenger Daniel Chung with 204,039 votes, or 58.72%, compared to Chung’s 143,171 votes, or 41.20 percent. Rosen is on track to retain his position without proceeding to a November runoff, pending final certification of results.
County Assessor Neysa Fligor and County Sheriff Robert Jonsen both ran unopposed and will retain their seats. Fligor was elected to fill the position in a special election last year after former longtime Assessor Larry Stone retired in July 2025.
Santa Clara Valley Open Space Authority Measure D, a citizen’s initiative that would levy a parcel tax of 2 cents per square foot of building area to generate an estimated $17 million annually for the agency, appears to have passed. With 143,159 yes votes, or 55.30%, against 115,722 no votes, or 44.70%, the measure has cleared the simple majority required for approval.
Revenue from the tax would be directed toward wildfire risk reduction, open space preservation, wildlife corridor maintenance and expansion of the public trail system. Opponents had argued the measure added to an already burdensome tax load and questioned the adequacy of its oversight provisions.
Results remain unofficial pending final certification by the Santa Clara County Registrar of Voters.
