The proclamation shall set the date of the election, which shall be not less than fourteen or more than thirty days after the proclamation is issued, and shall be sent by the governor to each election authority responsible for conducting the special primary election. In the proclamation, the governor shall specify the name of each candidate for the office to be voted on at the election, and the special primary election shall be conducted and the votes counted as in other primary elections.

2. If two or more persons receive an equal number of votes for nomination as a party's candidate for any other office, except party committeeman or committeewoman, and a higher number of votes than any other candidate for the same office on the same party ballot, the officer with whom such candidates filed their declarations of candidacy shall, immediately after the results of the election have been certified, issue a proclamation stating the fact and ordering a special primary election to determine the party's nominee for the office. The proclamation shall set the date of the election, which shall be not less than fourteen or more than thirty days after the proclamation is issued, and shall be sent by the officer to each election authority responsible for conducting the special primary election. In the proclamation, the officer shall specify the name of each candidate for the office to be voted on at the election, and the special primary election shall be conducted and the votes counted as in other primary elections.

3. As an alternative to the procedure prescribed in subsections 1 and 2 of this section, if the candidates who received an equal number of votes in such election agree to the procedure prescribed in this subsection, the officer with whom such candidates filed their declarations of candidacy may, after notification of the time and place of such drawing given to each such candidate at least five days before such drawing, determine the winner of such election by lot. Any candidate who received an equal number of votes may decline to have his or her name put into such drawing.
