The 2004 General Election canvass was completed on November 9, 2004.

Following the canvass, an Auditor's Office employee found a box containing 121 challenged and provisional ballots. These ballots had been reviewed by the absentee board and approved for counting, but had not actually been opened and counted.

The Auditor contacted the Secretary of State's office and was informed that, while the 121 ballots should have been counted, it was now too late. The votes could not be counted and the canvass could not be amended.

However, the Auditor reconvened the absentee board and had the additional ballots opened and counted. The Johnson County Board of Supervisors certified the new results on November 23, 2004, and the Auditor released these amended totals under the heading "Report of Ballot Information."  The additional 121 ballots did not affect the outcome of any contest.

The statewide results as certified by the Secretary of State still include the original November 9 canvass totals with 66,171 total voters. County records from 2004 to 2021 listed only the "Report of Ballot Information" totals with 66,292 voters.
