Introduction
May 18, 2026 — TODAY is the last day to register to vote in California’s June 2 statewide primary election. If you are not already registered, or if your registration needs to be updated, you must act before midnight. California offers same-day registration at county elections offices, but for most voters, completing the process online is the fastest and most reliable option.
For Walnut Creek residents, the June 2 ballot includes several races and measures with direct local impact. Here’s what you need to know to make your voice heard.
How to Register
California residents can register to vote online through the Secretary of State’s website at registertovote.ca.gov. The process takes approximately five minutes and requires your California driver’s license or state ID number, the last four digits of your Social Security number, and your date of birth. You can also check your existing registration status at the same site.
For same-day registration, Contra Costa County residents can visit the Elections Department office at 555 Escobar Street in Martinez during business hours. Same-day registrants receive a provisional ballot that is counted once the county verifies their eligibility.
What’s on the Ballot for Walnut Creek
While candidates for statewide offices will dominate much of the attention, Walnut Creek voters will also decide on measures that directly affect the community:
- Contra Costa County Urban Limit Line renewal — Measure U would extend the boundary restricting urban development to 35% of county land until 2051, preserving open space surrounding Walnut Creek
- Congressional primaries — California’s 10th Congressional District, represented by Mark DeSaulnier, is on the ballot
- State legislative races — The 9th State Senate district (Tim Grayson) and Assembly districts covering Contra Costa County appear on the ballot
- School bond measures — Voters in several Bay Area districts will consider $688 million in school facility bonds
Conclusion
California’s primary elections often see lower turnout than general elections, but they are where many critical decisions are made. The deadline is midnight tonight. Register now at registertovote.ca.gov.
