Democratic State Central Committee is composed of approximately 2,900 members that are appointed by Democratic elected officials and nominees, elected by county central committees, and elected in Assembly district election meetings, in roughly equal proportion. The executive board is composed of approximately 320 members and holds all powers and duties of the California Democratic Party while the state central committee or its conventions are not in session. There are semi-autonomous county central committees for each of California's 54 counties. Each county central committee elects 4 members, plus a member for each 10,000 registered Democrats in that county, to the state central committee. The state central committee bylaws specify that county central committees may provide for the election of their allocation of membership on an at-large basis, or by county supervisor districts or Assembly districts, or by any combination thereof. "Assembly district election meetings" are held biennially in January in every odd-numbered year (immediately after elections for the governor and president) within each of California's 80 Assembly districts. Participation is open to all registered Democrats within the Assembly district. Each meeting elects 14 members to the state central committee, divided as equally as possible between men and women. County central committees At every direct primary election, a county central committee is elected in each county. The California Elections Code specifies how county central committee members are elected. Candidates for county central committees are nominated pursuant to division 8, part 1, chapter 1 of the Elections Code, which defines requirements such as the number of Democratic registered voters required (20–40) to sign a nomination. A county central committee may also select its members at any time by holding a caucus or convention or by using any other method of selection approved by the committee. If the number of candidates nominated for election does not exceed the number of candidates to be elected, the candidates are not listed on the ballots, but are instead declared elected by the board of supervisors.
