Did you realize we have a primary election coming up on June 7? The last day to register to vote in that election is May 23. (California also has same-day Conditional Voter Registration.) If you have changed your name or political affiliation, you must re-register. You can check your current registration here. If you are a new CA resident, you can register here.
And what will be on the ballot? Statewide offices and candidate statements are explained in the Official Voter Information Guide. The Santa Clara County guide is not yet available. Vote-by-mail ballots will start arriving in the mail after May 9. Voters in Santa Clara County then can vote early by mail, or by taking their ballot to any of ~100 Vote Centers up to three days before and including Election Day.
