Running for Countywide Office in Martinez means competing for a countywide seat (Sheriff, DA, Assessor, Clerk-Recorder, Treasurer-Tax Collector) in front of every registered voter in the county. Most Martinez countywide office campaigns since 2018 have landed in the $100K–$2M depending on the office range and won on endorsements, earned media, ballot designation, and broad-reach mail. As the Contra Costa County seat, Martinez has an outsized civic awareness for its size. The city's refinery heritage and waterfront location create campaigns focused on economic transition, environmental stewardship, and preserving the historic downtown. Filing paperwork goes through the county elections office — plan for the March filing window for the June primary, an FPPC Form 410 the moment fundraising crosses $2,000, and a ballot designation that survives challenge under Elections Code §13107. Local Campaign Pros runs countywide office campaigns for Martinez candidates end-to-end — strategy, mail design and print, voter data, lawn signs, field, and FPPC compliance built on the Contra Costa County voter file.
