The ballots for a primary election shall be printed with a different color designation for each political party that is included on the ballot. Unless otherwise provided by law, the ballot shall be printed, "official ballot of the __________ party, primary election (date), ___________ precinct, county (or city or town) of __________, state of Arizona". Below the heading shall be placed the title of each office to be voted for, and an instruction to the voter as to how many are to be voted for for the particular office, thus: "vote for not more than __________" (insert the number to be elected), under which shall be placed alphabetically and alternated, as provided by law, the names of all the party’s candidates to be voted for in each precinct of the county or precinct or ward of the city or town for whom nomination papers have been filed for such office, leaving as many blank lines as there are offices under that title to be filled, followed by a place for the voter to make a mark to indicate the voter’s choice either to the right or the left of the candidate’s name, and of the blank line. Double or more columns may be arranged on the ballot. In other respects the ballot shall conform as nearly as possible to the ballot prescribed for general elections.
