Sonoma County Election Results Finalized as Runoff Fields Hold Steady The final certification of the June primary election in Sonoma County confirms that the matchups for the two open seats on the Board of Supervisors remain unchanged for the November runoffs. Top local election officials reported higher-than-average voter participation despite mail-in delivery issues.

Following weeks of meticulous ballot processing, the final election data for the June 2 primary has been certified in Sonoma County, locking in the candidate pairs for a duo of November runoffs to fill open seats on the Sonoma County Board of Supervisors.

The final data release published on Thursday underscores the region’s historic trend of achieving elevated voter participation rates. However, Sonoma County Registrar of Voters Evelyn Mendez issued a critical caveat regarding the results, disclosing that approximately 1,598 ballots could not legally be counted.

Representing less than 1% of the total countywide vote, these excluded ballots arrived too late or bore tardy postmarks. Mendez partially attributed the voting delays to systemic understaffing within the United States Postal Service.

Countywide voter turnout officially concluded at 54.55%, exceeding the registrar’s initial forecasts. The final metric stands substantially higher than the broader California benchmark, with the latest preliminary figures indicating that just over 40% of the state’s registered electorate participated in the primary.

Mendez expressed immense satisfaction with the local engagement, stating she felt deeply proud that regional citizens consistently show up to ensure their community priorities are heard.

The robust local turnout was primarily stimulated by a pair of highly competitive supervisor races in the 2nd and 4th districts. The open seats represent a political milestone, marking the first instance in 16 years that two positions on the five-member governing board lacked an incumbent candidate.

The voting figures formalized on Thursday merely cemented the exact runoff configurations that had crystallized two weeks prior during early returns.

In the southern 2nd District, the electorate will choose between Joanna Paun, a current Petaluma City Schools trustee, and Sylvia Lemus, the mayor of Cotati. This specific political pairing ensures that a woman of color will secure the seat, establishing a female board majority for only the second time in county history.

Paun, a progressive contender backed by some of the most influential labor unions in the county, secured 41.34% of the total vote. Meanwhile, Lemus, a centrist candidate carrying endorsements from prominent agricultural and commercial organizations, captured 25.1% of the vote.

The remaining candidates in the 2nd District primary field included Shelina Moreda, a professional motorcycle racer belonging to a Petaluma-area dairy farming family, who earned 19.04% of the vote. John King, a Penngrove rancher and operational engineer making his third run for the board, secured 14.51%.

Out of the 67,767 citizens registered to vote within the 2nd District boundary, exactly 34,147 ballots were successfully cast in this supervisor race.

Geographically, the 2nd District encompasses a vast portion of southern Sonoma County, spanning the municipalities of Petaluma, Penngrove, Cotati, and a fraction of Rohnert Park, alongside the agricultural belt running from the coast eastward to San Pablo Bay.

On the northern edge of the county, progressive candidate Melanie Bagby and centrist contender Tom Schwedhelm are set to battle for the open 4th District supervisor seat.

While early returns indicated an exceptionally tight race, Bagby ultimately built a commanding lead, whereas Schwedhelm narrowly edged out Todd Lands to claim the second runoff spot.

The final Thursday updates showed Bagby, a former council member and mayor of Cloverdale, leading with 37.91% of the vote. Schwedhelm, a retired police chief and former mayor of Santa Rosa, followed with 31.69%, while Lands, a Cloverdale City Council member and current vice mayor, fell just short at 30.40%.

The 4th District contains 63,036 registered voters and covers northeastern Sonoma County, including Cloverdale, Healdsburg, Windsor, northern Santa Rosa, and the premium viticultural regions of the Alexander and Dry Creek valleys. Total ballots cast in this race reached 30,910.

Mendez reiterated that while the final 54.55% turnout metric was highly encouraging, the 1,598 invalid mail ballots caused immense administrative frustration.

The vast majority of post-election inquiries handled by her staff involve disenfranchised individuals demanding explanations as to why their mail-in ballots were excluded from the final tally.

According to Mendez, the primary issue stems from voters depositing their envelopes into mailboxes or handing them to carriers on Election Day itself, unaware that immediate postmarking is not guaranteed. Because local mail is routed through a major sorting facility in San Francisco, regional processing can add multiple days to transit times.

California election law dictates that mail-in ballots must arrive at local election headquarters within 7 days of Election Day to be eligible for tabulation.

Reiterating warnings distributed before June 2, Mendez emphasized that the absolute best way to ensure a valid mail ballot is to physically bring it into a post office branch and request an immediate hand-stamp postmark from a clerk.

Though the volume of excluded mail remains a painful statistic for Mendez and the affected citizens, the uncounted envelopes represent a minor 0.91% fraction compared to the 174,913 ballots that were successfully processed.

The registrar’s office also flagged roughly 600 additional ballots containing technical discrepancies, primarily involving voter signatures that failed to match official registration records. For these specific cases, staff contacted voters directly to allow them to correct the errors. The statutory deadline to cure these signatures expired on Wednesday.

Mendez noted that signature mismatches and missing signatures are a universal challenge across every California county, calling it deeply unfortunate when such a high volume of votes are disqualified over preventable mistakes.

With the primary certified, local election authorities are pivoting toward planning for November. The recent friction surrounding delayed postmarks and unverified signatures has crystallized exactly what public outreach messaging needs to be emphasized.

Mendez urged voters to submit their ballots early rather than waiting until the final deadline, noting that anyone needing to resolve errors should visit a vote center or the main office immediately. She strongly advised utilizing official county drop boxes rather than trusting the standard postal network.

Future Outlook

As Sonoma County transitions toward the November general election, public education campaigns will shift heavily toward secure balloting methods to prevent a recurrence of the mail delays seen on June 2. The upcoming election will draw intense interest as the 2nd District prepares to alter the demographic layout of local governance, guaranteeing a historic female majority on the five-member Board of Supervisors. Political analysts expect high-stakes campaigns from both districts as progressives and centrists fight to secure the open non-incumbent seats.

When a signature is missing or fails to match the file on record, the registrar’s office contacts the voter directly to provide an opportunity to correct or “cure” the discrepancy.

How can local voters guarantee their mail-in ballots are counted in November?

Election officials strongly recommend using official county drop boxes or visiting an active vote center instead of utilizing standard postal mailboxes. If a voter must use the mail on Election Day, they should take the envelope directly to a post office counter and explicitly request a hand-stamped postmark.
