Colorado Revised Statutes Title 1. Elections § 1-13.5-612. Defective ballots

(1) If an elector votes for more names than there are persons to be elected to an office, or, if it is impossible to determine the choice of an elector for an office to be filled, the elector's ballot will not be counted for that office. A defective or an incomplete cross marked on any ballot in a proper place must be counted if there is no other mark or cross on such ballot indicating an intention to vote for some person other than those indicated by the first mentioned defective cross or mark. No ballot without the official endorsement, except as provided in section 1-13.5-704, may be deposited in the ballot box, and only ballots provided in accordance with this article shall be counted. If the election judges discover in the counting of votes that the name of any candidate voted for is misspelled or the initial letters of a candidate's given name are transposed or omitted in part or altogether on the ballot, the vote for the candidate must be counted if the intention of the elector to vote for the candidate is apparent.

(2) Ballots not counted must be marked “defective” on the back thereof and shall be preserved for such time as is provided in section 1-13.5-616 for ballots and destroyed as therein directed.
