California primary election 2024: How to vote in the presidential primary on Super Tuesday (2024)

On Super Tuesday, March 5, California will join more than a dozen states and one territory in casting ballots in their local presidential primaries.

Votes cast in the primary elections will help determine the Republican and Democratic presidential nominees and will play a significant role in shaping who will be on the November ballot in closely watched Congressional races.

California holds the distinction of committing the largest number of delegates to presidential candidates March 5, followed closely by Texas.

This year’s primary is the first time in decades Californians will get to cast a ballot for an open U.S. Senate seat, following the death of Sen. Dianne Feinstein in September. Voters statewide will also weigh in on a proposition championed by Gov. Gavin Newsom that would commit billions of dollars to mental health services.

Here’s what to know about voting in California’s primaries for the 2024 election cycle.

When are polls open on Super Tuesday?

California's primary election is Super Tuesday, March 5. Polls are open 7 a.m. to 8 p.m.

Is it too late to mail in my ballot?

Any ballots mailed in must be postmarked before or on March 5.

Those with mail-in ballots can also drop them off at listed polling locations on election day.

Which presidential candidates will be on my ballot in California?

Unlike the November general election, primary ballots vary depending on the voter's party registration.

California holds a "modified" closed primary for presidential elections, meaning registered voters can only cast votes for candidates of their own political party, unless they request to vote differently via a specially requestedballot.

The exception is the Republican Party, which only allows registered Republicans to vote for GOP candidates in primaries. To check your registration status, including party affiliation, visitregistertovote.ca.gov.

Californians registered as a "No Party Preference" voter will not have any presidential candidates on their March 5 ballot.

What else is on my ballot Tuesday?

All registered Californians can vote for a candidate for U.S. Senate. Unlike the presidential primary, the state holds nonpartisan primaries for Senate, allowing voters to throw their support behind any candidate regardless of party. The top two candidates advance to the general election.

There will be two U.S. Senate contests on the primary ballot this year. The first contest listed on the ballot is for a regular six-year term ending in 2031, with more than two dozen candidates. The second is for the remainder of the Feinstein's term, ending Jan. 3, 2025. That race has seven candidates, including front-runners Democratic Reps. Adam Schiff, Barbara Lee and Katie Porter, and Republican Steve Garvey.

California voters will also see Proposition 1 on their ballot. The two-part initiative is meant to overhaul the state's mental health system via a $6.4 billion bond, which would focus on funding new mental health treatment facilities and housing for those with mental health conditions experiencing, or at risk of, homelessness.
