Oceanside City Council member Ryan Keim held a diminishing advantage over incumbent Mayor Esther Sanchez in the latest results released Monday in the Nov. 5 election.

The new numbers reduced his previous lead of 591 votes to a slim margin of 239 votes. About 140,000 ballots remain to be counted countywide, with the next update expected Wednesday at 6 p.m., according to the San Diego County Registrar of Voters.

Keim is a former Oceanside police officer appointed to a vacant council position in January 2019, then elected to a four-year term in 2020. The mayor’s only opponent, he has been narrowly ahead since the first results were announced.

Sanchez, an attorney and former public defender, has been a council member since 2000 and was first elected mayor in 2020.

The Oceanside City Treasurer election is also close.

Incumbent city treasurer Victor Roy led his two opponents in early results, but slipped to second place late last week.

Phyllis Dominguez, a small business owner and 22-year Oceanside resident, was ahead by nearly 800 votes with Monday’s results. Jack Fernandes remained in third place.

Both Roy and Fernandes have hot spots in their records.

An independent investigation conducted for the city in 2022 found that Roy had behaved poorly in his job, violated city policies, and used library computers to view inappropriate material. Fernandes publicly admitted to being arrested for drunk driving before the election, and a police report showed he was involved in an apparently unrelated “road rage” incident in La Jolla.

Dominguez promised to restore confidence in the office, in response to questions from the San Diego Union-Tribune before the election.

“Due to a history of controversy within this office,” Dominguez said, “the new city treasurer will need to restore the credibility of the office and rebuild the necessary relationships with other departments to become an effective watchdog of taxpayers’ money and trusted finances.

Two races for Oceanside City Council remained unchanged with additional results.

Jimmy Figueroa, a local nonprofit leader, edges out the next closest candidate, Laura Bassett, for the District 3 seat now held by Keim. The other candidates in this district are Tom DeMooy and Austin Sorensen.

In District 4, incumbent President Peter Weiss leads by more than 20 percentage points over his two opponents, Omar Hashimi and Amber Kae Niuatoa.

Nearly 70% of Oceanside voters supported approving an additional 10 years for Measure X, the temporary half-cent sales tax increase approved in 2018 and otherwise set to expire in 2026.
