Idaho Code § 70-1213
In the event valid nominating petitions for more than two (2) candidates remain on file for the office of port district commissioner in any commissioner district after the last day for withdrawal of candidacy, the county clerk shall conduct a port district primary at the same time he conducts the county primary election. At all such nominating elections, the nomination of candidates shall be nonpartisan, and the ballot, or portion of ballot, to be used for such nominating election shall be designated "Port District Nominating Ballot, Port of ...." (inserting the name of the appropriate port district), and such ballot shall not have upon it any political party designation nor statement of any affiliation whatever of any candidate named thereon. In the event no more than two (2) such nominating petitions remain on file for the office of port district commissioner in any port commissioner district after the last day for withdrawal of candidacy, the county clerk shall not conduct such port district primary, but shall cause the name of such candidates to be printed upon the port district ballot for the general election only. Such general election ballot, or portion of the ballot for use in such port election, shall be designated "Official Ballot, Port of ...." (inserting therein the name of such port district), and shall contain no political party designation nor statement of any affiliation whatsoever of any candidate named thereon.
In the event a primary election is conducted for the office of port district commissioner, the name of the person who receives the greatest number of votes and of the person who receives the second greatest number of votes for each commissioner district, shall appear upon the port district general election ballot under the designation for each respective office. Names of candidates printed on the district primary and general election ballots shall be rotated, as nearly as may be, in the same manner as are names of candidates under the election laws of this state relating to the election of county officers.
Any port commissioner may be recalled in accordance with the statutory provisions for the recall of county officers then in effect; provided, however, that only voters residing within and qualified to vote within the port district may vote at any such recall election.
