Primary Elections in California

What is a voter-nominated office?

The Top Two Candidates Open Primary Act, which took effect January 1, 2011, created "voter-nominated" offices. The Top Two Candidates Open Primary Act does not apply to candidates running for U.S. President, county central committees, or local offices.

Most of the offices that were previously known as "partisan" are now known as "voter-nominated" offices. Voter-nominated offices are state constitutional offices, state legislative offices, and U.S. congressional offices. The only "partisan offices" now are the offices of U.S. President and county central committee.

How are primary elections conducted in California?

All candidates for voter-nominated offices are listed on one ballot and only the top two vote-getters in the primary election – regardless of party preference - move on to the general election. Write-in candidates for voter-nominated offices can only run in the primary election. A write-in candidate will only move on to the general election if the candidate is one of the top two vote-getters in the primary election.

Prior to the Top Two Candidates Open Primary Act, the top vote-getter from each qualified political party, as well as any write-in candidate who received a certain percentage of votes, moved on to the general election.
