About the format of this abstract

Results contained in the abstract

This publication contains the official certified results for the 2019 Odd-Year, 2020 Presidential Primary, 2020 Primary, and 2020 General Elections for all candidates, judicial retention races, and ballot issues certified to the ballot by the Colorado Secretary of State's Office.

Results & officer information reported by the counties

The election results and county officer information in this abstract were obtained from each of Colorado’s 64 counties. The results in this abstract are more accurate than the compiled and totaled returns reported on the Secretary of State’s website immediately after the election because they account for any miscalculations in the totals initially reported by each county.

Judicial officer information

Judicial officer information, including dates of oath and terms of office, was provided by the Office of the State Court Administrator.

Registered voters, ballots cast, & turnout

In the results section of this abstract, the column titled “Registered Voters” is the number of registered voters eligible to vote in each contest. The column titled “Ballots Cast” is the number of voters who cast a ballot in each contest. The column titled “Turnout %” reflects the percentage of registered voters who cast a ballot in each contest.

The county-level turnout, located at the back of the abstract, is provided using both active voters and registered voters. Colorado statute currently requires that county-level turnout be reported by registered voters. However, prior to 2011, statute required that turnout be reported by active voters. To allow comparison of turnout data throughout the years, we have chosen to provide the turnout data for both active and registered voters.

Recent changes in Colorado law

In 2016, Colorado voters approved citizen initiative Proposition 107.

Proposition 107 created presidential primary elections in Colorado. This new election was held on March 3, 2020, a date set by the governor. Unaffiliated voters were allowed to participate in the presidential primary as is currently allowed in Colorado's primary election. The last Colorado presidential primary election was held in 2000. Between 2004-2016, political parties held caucuses in lieu of a presidential primary election.
