Collier County Supervisor of Elections office will sent its first mailing of requested vote-by-mail ballots to domestic voters Feb. 8 for the upcoming Presidential Preference Primary Election. All vote-by-mail requests from prior years have expired. The deadline for voters to request a ballot to be delivered by mail for the Presidential Preference Primary Election is 5 p.m. March 7. Vote-by-mail ballot requests can be made by clicking here. Voted ballots must be physically returned (not just postmarked) to the Supervisor of Elections by 7 p.m. March 19. The United States Postal Service recommends voters mail their voted ballots one week before the due date to account for any unforeseen events. Voted ballots can also be dropped off at any of the 11 early voting locations between 10:00 a.m. and 6:00 p.m. March 9-16.
