Ballots go out for the November 3 election

Boulder County mails ballots for the November 3, 2026 coordinated election starting October 2, and its 24-hour drop boxes open the same day. Vote centers open October 19. Registered electors living inside the proposed Niwot boundary receive the incorporation questions and fiscal issues on their ballot; the plain-language summary is in our election guide.

Colorado has no registration cutoff: an eligible voter can register and vote through Election Day.
