(a) The registration books must be closed on the 29th day before each election and must remain closed until after that election. If an election is called and there are fewer than 29 days before that election, the registration books must be closed immediately.
(c) When the registration books are closed for an upcoming election, an update or change to a voter’s party affiliation made pursuant to s. 97.1031 shall be permitted for that upcoming election unless such election is for the purpose of nominating a political party nominee, in which case the update or change shall be permitted only for the purpose of subsequent elections.
(2) When an elector seeks to change party affiliation, the elector shall notify his or her supervisor of elections or other voter registration official by using a signed written notice that contains the elector’s date of birth or voter registration number.
As soon as the supervisor receives the written request for a party affiliation change, the supervisor will make the change on the voter’s information record and send the voter a new voter registration information card.
