That's right. The local officials represent the citizens of the district in which they were elected, not any political party. "Everyone"may know that Joe Blow is a Republican and Jane Doe is a Democrat, but Joe and Jane cannot officially represent their parties, nor can the party openly support them--including money for campaign expenses. The League of Women Voters (a nonpartisan political organization) puts it this way
Q. What is a nonpartisan office?
It is an office for which candidates' names appear on the ballot without party designation. No party may nominate a candidate for nonpartisan office.
Q. Which offices are nonpartisan?
Local offices such as most city council members, county supervisors, all judgeships, including the statewide office of member of the California Supreme Court, and all school boards, including the statewide offices of Superintendent of Public Instruction and Insurance Commissioner, are nonpartisan.
Q. Are there nonpartisan primaries?
Yes. Some local nonpartisan primaries such as those for judges are usually held at the same time as the statewide regular primary. A candidate for a nonpartisan office who is on the primary ballot is selected if he or she wins more than 50% of the vote. If not, there is a runoff election in November between the top two candidates.
Q. Do all nonpartisan offices use primaries?
No, some nonpartisan offices, such as most city councils and school boards, do not use primaries. Candidates run as independents and the person with the most votes wins even if it is not a majority.
