‡ The standard deadline for the Registrar of Voters Office to receive Vote-by-Mail ballots which are postmarked on or before Election Day would be 11/11/25 (7 days after Election Day), but since that day is a County holiday (Veterans’ Day), the deadline is moved back to the next business day (11/12/25)
