The only candidates whose names shall be placed on ballots for the election shall be those candidates who:

(1.5) No later than the sixty-fifth day before the presidential primary election, a person whose name has been qualified to be placed on the ballot may file with the secretary of state an affidavit stating that the person is not a candidate for the office of the president of the United States and requesting that the person's name not be included in the list of names certified by the secretary of state in accordance with subsection (1) of this section. The secretary of state shall not include in the list the name of a person who timely files an affidavit.

(2) The names of candidates appearing on any presidential primary ballot must be in an order determined by lot. The secretary of state shall determine the method of drawing lots.

(3) Except as otherwise prohibited by political party rules, the state chairperson of a political party may request the secretary to provide a place on the primary ballot for electors who have no presidential candidate preference to register a vote to send a noncommitted delegate to the political party's national convention. To be valid, this request must be received by the secretary of state no later than seventy days before the presidential primary election.

(4) Any challenge to the listing of any candidate on the presidential primary election ballot must be made in writing and filed with the district court in accordance with section 1-1-113(1) no later than five days after the filing deadline for candidates. Any such challenge must provide notice in a summary manner of an alleged impropriety that gives rise to the complaint. No later than five days after the challenge is filed, a hearing must be held at which time the district court shall hear the challenge and assess the validity of all alleged improprieties. The district court shall issue findings of fact and conclusions of law no later than forty-eight hours after the hearing. The party filing the challenge has the burden to sustain the challenge by a preponderance of the evidence. Any order entered by the district court may be reviewed in accordance with section 1-1-113(3).
