Idaho Statutes Title 34. Elections § 34-908. Each ballot to carry official election ballot identification on outside--Marking of ballot by voter

(1) Every ballot used at any primary, general or special election shall be marked on the outside with the official election ballot identification before it is given to the voter. At this time the election official distributing the ballots shall give the voter instructions in regard to folding the ballot after he has voted.

(2) The voter shall mark his ballot with a cross (X) or other mark sufficient to show his intent in the place provided after the name of the candidate for whom he intends to vote for each office.

(3) If a person votes by writing the name of a candidate on the ballot, such act shall constitute a vote for the person's name who appears without the necessity of placing a mark after the name written on the ballot, unless such a mark is required by a vote tally system.
