Why Update Your Affiliation?
In California, your political party affiliation determines which candidates you can vote for in certain primary elections. While the state utilizes a “top-two” primary system for most offices, some parties may have specific rules regarding who can participate in their presidential primary elections.
How to Change Your Party
The most efficient way to change your political party is to re-register to vote. Because your party preference is a key part of your registration record, submitting a new application effectively overwrites your previous choice.
Online Registration
The fastest method is to visit the official California Secretary of State website at registertovote.ca.gov. You can complete the application electronically in just a few minutes. You will need your California driver license or state ID number, the last four digits of your social security number, and your date of birth.
Paper Applications
If you prefer not to use the online portal, you can obtain a paper voter registration application. These are readily available at:
- County elections offices
- Public libraries
- Department of Motor Vehicles (DMV) offices
- U.S. Post Offices
Important Deadlines
It is vital to keep track of election dates. In California, the deadline to register to vote or update your registration is 15 days before Election Day. For the upcoming election on November 3, 2026, your application must be postmarked or submitted electronically no later than October 19, 2026. Registering early ensures your information is processed in time for the ballot mailing process.
Eligibility Requirements
To update your registration, you must still meet the standard requirements for California voters:
- Be a United States citizen and a resident of California.
- Be at least 18 years old by Election Day.
- Not currently serving a state or federal prison term for a felony conviction.
- Not currently found mentally incompetent to vote by a court.
