Jim Irizarry
Democrat
Has served the San Mateo County office for over three decades, including 13 years as the deputy/assistant to outgoing Assessor-County Clerk-Recorder Mark Church. Pitches institutional continuity and operational depth. The campaign has been overshadowed by reporting that Irizarry was registered with the American Independent Party from at least 1996 through 2015 — a fact Irizarry says was a clerical error he eventually fixed; he re-registered as a Democrat in July 2023.
