C.R.S. § 31-10-903: Ballots changed if candidate dies or withdraws.

If any person duly nominated dies before the day fixed for the election and the fact of such death becomes known to the clerk or withdraws by filing an affidavit of withdrawal with the clerk before the date fixed for election, the name of the deceased or withdrawn candidate shall not be printed upon the ballots for the election. If the ballots are already printed, the name of the deceased candidate or withdrawn candidate shall be erased or canceled, if possible, before the ballots are delivered to the voters.
