What are 2026 June primary key dates, deadlines? Your election questions answered

California’s primary election is June 2. Ballots are being sent and The Bee Voter Guide breaks down the major races and issues. Our reporters Camila Pedrosa, Angela Rodriguez and Veronica Fernandez-Alvarado have helped gather information to arm you before you vote, including information on how to research your ballot and what exactly does a county supervisor do.

What to Know

• How to research your ballot: Some local races, including Sacramento City Council and County Board of Supervisors, can be decided in June with a simple majority. Resources include vote411.org from the League of Women Voters, county Voter Information Guides and news organization voter guides.

• What county boards of supervisors do: Boards oversee budgets, child support systems such as foster care, property tax collection and road maintenance in unincorporated areas. All California counties have five-member boards except San Francisco, which has 11.

• How to register: The deadline to register is Monday, May 18. California offers same-day conditional voter registration at county elections offices, polling places or vote centers on Election Day for those who miss the deadline.

• Ballot return deadlines: Polls are open from 7 a.m. to 8 p.m. on June 2. Mail-in ballots must be postmarked by Election Day and received within seven days. Voters in line by 7:59 p.m. still have the right to vote.

• Fixing a ballot mistake: Voters have up to three chances to cast a ballot, including the original. You can exchange an incorrectly marked ballot at your county elections office or request a replacement.

• Tracking your ballot: The Secretary of State’s “Where’s My Ballot?” system notifies registered voters by text, email or phone when ballots are mailed, received and counted.
