On the ballot

This person presides over City Council meetings and represents Costa Mesa publicly, but votes as one of seven members (the Mayor plus six district councilmembers) on the budget and city ordinances -- day-to-day city government runs through an appointed city manager. Costa Mesa's mayor is the only council seat elected citywide rather than by district. A 2-year term, capped at two consecutive terms.

Two sitting councilmembers are running against each other for Costa Mesa's open Mayor's seat: Mike Buley (District 1) and Loren Gameros (District 2). Mayor John Stephens is term-limited and cannot run again. Whichever candidate gets the most votes on November 3 wins outright; there's no runoff.

Costa Mesa's mayor presides over City Council meetings and represents the city publicly, but votes as one of seven members (the mayor plus six district councilmembers) on the budget and city ordinances -- day-to-day city government runs through an appointed city manager. It's the only council seat elected citywide rather than by district. A 2-year term, capped at two consecutive terms.

Neither candidate is defending this specific seat, so the race turns on each man's record in his own district and how he'd apply it citywide. Buley, an attorney elected to District 1 in 2024, campaigns on business permitting, public safety staffing, and fiscal restraint. Gameros, elected to District 2 in 2020 and reelected unopposed in 2024, campaigns on a 'boots on the ground' record he says includes opening the city's permanent Bridge Shelter for homelessness services and expanding public access to Luke Davis Field. Costa Mesa First, a local growth-policy PAC, notes Gameros supported those specific council actions and also flags that critics see his visible constituent work as concentrated in his own Halecrest neighborhood -- a characterization from an advocacy group, not this dataset's own judgment.

Mike Buley

A civil litigation trial attorney and law-firm owner of more than 30 years, elected to City Council District 1 in November 2024 -- his council seat isn't up this cycle, so he's giving it up to run for mayor if he wins. His campaign centers on streamlining business permits to attract investment and jobs, keeping police and fire fully staffed, and continuing to fund youth sports, recreation, and neighborhood events. He says he wants to expand resident involvement through new financial-oversight and city-planning committees. On the council, Costa Mesa First's tracking says he has supported Flock public-safety cameras and opposed updating the Fairview Park Master Plan.

Strengths

A law career built around civil litigation gives him direct familiarity with contracts and regulation, which he frames as an asset for cutting permitting delays.

Trade-offs

Only about two years of council experience by the time voters decide this race, the shortest tenure of the two candidates.

Keep in mind

No CAL-ACCESS record was checked for his campaign in this pass -- the state's filer-search tool was unreachable throughout the research window -- see Financial info.

Loren Gameros

An instructor and building-inspection trades coordinator, elected to City Council District 2 in November 2020 and reelected unopposed in 2024 -- like Buley, his own council seat isn't up this cycle. He describes his approach as 'boots on the ground,' built around being personally present in neighborhoods. His platform centers on public safety, expanding youth and family recreation, maintaining roads and parks, and balancing growth with neighborhood character and local business support. He points to supporting the opening of the city's permanent Bridge Shelter (2021), increased city staffing (2022), and public access to Luke Davis Field (2023) as council-term accomplishments.

Strengths

Roughly six years of council experience by election day, the longest tenure of the two candidates, with specific homelessness-services and recreation-access actions he can point to.

Trade-offs

A local PAC says some Mesa North residents report less visible engagement from him than his home neighborhood, Halecrest -- an advocacy source's critique, not this dataset's own finding.
