Running for Countywide Office in Brentwood means competing for a countywide seat (Sheriff, DA, Assessor, Clerk-Recorder, Treasurer-Tax Collector) in front of every registered voter in the county. Most Brentwood 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. Brentwood has transformed from an agricultural town to a booming suburb in just two decades. The tension between preserving farmland and accommodating new residents defines local politics, with newer homeowners pushing for services and longtime families advocating for rural character. 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 Brentwood 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.
