California Presidential Primary Election

March 5, 2024
(33rd edition)

About This Election

What's on the ballot:  

  • Presidential candidates seeking their political party's nomination

  • The office of U.S. Senate will have TWO separate contests on the ballot. You may vote on both. The first contest is the regular election for the full 6-year term of office beginning 1/3/25. The second contest is a "special vacancy election" for the remainder of the term ending on 1/3/25. 

  • U.S. House of Representatives, State Assembly and odd-numbered State Senate districts

  • Proposition 1, a statewide bond measure

  • Local contests for county, municipal and special district offices, judges and local measures 


Your voting choices:

  • In California state and federal elections, under California's "Top Two" open primary law, all registered voters can vote in the primary for any candidate of any party regardless of voters' or candidates' party affiliations. However, in a Presidential Primary election, voters registered with a political party can only choose among candidates for president who are registered with the same party (the same is true for party central committee elections). In this election, Independent, "No Party Preference" voters have have the option of voting in the Presidential primaries of the Democratic, Libertarian and American Independent parties; voters wishing to vote differently than their party registration allows must re-register to vote and update their party affiliation.

  • California local elections are nonpartisan; like state and federal contests, the top two vote-getters proceed to the General Election ballot, unless one candidate receives more than 50% of the Primary election vote, in which case that candidate won outright in the Primary, and the contest is over and does not appear on the General Election ballot.
  • All federal, state and local political district lines were redrawn after the 2020 Census to ensure Californians are equally represented. Visit CalMatters to look up your new state and federal districts.
