Running for Countywide Office in California puts you in front of every registered voter in the county. Most winning countywide office campaigns budget in the $100K–$2M depending on the office range and rely on endorsements, earned media, ballot designation, and broad-reach mail. Filing goes through the county elections office; plan for the March filing window for the June primary, FPPC Form 410 within 10 days of crossing $2,000 in fundraising, and a ballot designation that holds up under challenge. Local Campaign Pros runs countywide office campaigns end-to-end across every California county.
