Colorado Revised Statutes Title 1. Elections § 1-7-114. Write-in votes

(1) Eligible electors may cast a write-in vote for a candidate who has filed an affidavit of intent of write-in candidacy pursuant to section 1-4-1101 by writing the name of the person in the blank space provided for write-in candidates on the ballot. Each write-in vote may include a reasonably correct spelling of a given name, an initial or nickname, or both a given name and an initial or nickname, and shall include the last name of the person for whom the vote is intended. Whenever write-in votes are cast, they shall be counted only when the intention of the elector is clearly apparent.

(2) A vote for a write-in candidate shall not be counted unless that candidate is qualified to hold the office for which the elector's vote was cast.

(3) If the elector has cast more votes for an office than he or she is lawfully entitled to cast, by voting for both a candidate appearing on the ballot and a valid write-in candidate, neither of the votes for the office shall be counted.
