The election precincts, polling places and officials for any special primary or special election shall be the same as at the last preceding general election in that municipality unless changed according to law. When a special primary or special election is held on the same day as another primary or election, the same precincts, polling places and officials shall be used for both. If separate special election ballots are required pursuant to section 204D.25, separate ballot boxes shall be used.
An individual may register to vote at a special primary or special election at any time before the day that the polling place rosters for the special primary or special election are prepared by the secretary of state. The secretary of state shall provide the county auditors with notice of this date at least seven days before the printing of the rosters. This subdivision does not apply to a special election held on the same day as the state primary, state general election, or the regularly scheduled primary or general election of a municipality, school district, or special district.
