In-person advance voting ends at noon on Monday, November 2, 2026. No excuse needed.

Plan for your ballot to be received by your county election office, a drop box or a polling place in your county by the close of polls on Election Day, November 3. A court order currently also requires counting ballots postmarked by Election Day that arrive by the last mail delivery on Friday, November 6, but that order is under appeal and could change before the election.
