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

California’s primary election is June 2. Ballots are being sent, and our 2026 California Primary Voter Guide breaks down the major races and issues. Our reporters Camila Pedrosa, Angela Rodriguez and Veronica Fernandez-Alvarado have gathered additional details to help you vote, including information on how to register and research your ballot.

The following is a summary of their work. Click on the links below to access individual stories.

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

• How to register: The deadline to register to vote 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.

• BONUS: What do 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.
