If you missed the registration deadline
You can still vote. California lets you register and vote on the same day, in person, at the City Hall Voting Center or at any polling place through Election Day. The Department of Elections explains how same-day registration works. If you are not sure whether you are registered, check at voterstatus.sos.ca.gov.
Returning your ballot
Return your mail ballot by Election Day by mail, at an official drop box, or at any voting location. If you would rather vote in person, bring the mail ballot with you.
Finding Scott Wiener on your ballot
The race appears as United States Representative, District 11. District 11 covers most of San Francisco; the Department of Elections can confirm which districts your address falls in. Vote for one candidate. GrowUSA supports Scott Wiener, and our reasons are on the home page.
