Jefferson County voters can vote at the polls or by mail as a registered absentee voter.

MAIL BALLOT VOTERS: Ballots will be mailed by counties to absentee voters by October 9th, with voters receiving them a few days later. If you don't receive your ballot or if you damage it, make a mistake, or misplace your ballot, you can go in person to the Elections Office through Election Day to pick one up or receive a replacement ballot.

Voters who are not already registered to receive a mail ballot may vote early by absentee (mail) ballot by visiting the county Election Office between October 5th and November 2nd at noon to request a ballot.

POLLING PLACE VOTERS: You can find your polling place using the Secretary of State's Voter Portal. We also have county polling place locations listed below. These are subject to change.
