Idaho Code § 34-2206
The election shall be by ballot, separate from any ballot to be used at the same election, which ballot shall be prepared as follows: It shall first state the substance of the proposed constitutional amendment. This shall be followed by appropriate instructions to the voter. It shall then contain perpendicular columns of equal width headed respectively, in plain type, "For Ratification" and "Against Ratification." In the column headed "For Ratification" shall be placed the names of the candidates nominated in favor of ratification. In the column headed" Against Ratification" shall be placed the names of the candidates nominated as against ratification. The voter shall indicate his choice by making one or more cross-marks in the appropriate spaces provided on the ballot. No ballot shall be held void because any such cross-mark is irregular in character. The ballot shall be so arranged that the voter may, by making a single cross-mark, vote for the entire group of candidates whose names are comprised in any column:
The ballot shall be in substantially the following form:
