The City of San Diego operates under a Strong Mayor system. Under this system, the Mayor acts as the City’s Chief Executive Officer, similar to a President position. The Council serves as the legislative body, ensuring checks and balances on the Mayor’s authority. Although the City holds candidate elections every two years, any given seat is usually only up for election once every four years. The winning candidate is determined by a majority vote. If no candidate receives a majority of votes, the top two candidates who receive the highest number of votes in the Primary run against one another in the General. The City has a two-term limit, with each regular term lasting four years.
