2018 Primary Election Ballot Return Data

The data on this page is populated daily by 7 a.m. beginning 15 days prior to Election Day.

* The Ballots Returned data is reliant on Secretary of State data pushes, which vary. The page is updated daily from the prior day returns daily at 7 a.m. Beginning on Election Day at noon, page is updated every three hours from the SOS data. Thus, please keep in mind that on Election Night, ballot returns data has a several hour lag. Additionally, ballot returns include every ballot received, thus that figure will always be higher than what we ultimately count (e.g., not all voters cure their ballot, but their ballot will still be included in the returns data).

The figures include all mail ballots returned and all in-person ballots voted through the date listed. The cumulative total for the day is displayed in the calendar day. Below the calendar, returns are shown by city or by party. Use the buttons to switch between city and party returns.

* Note that the active registered voters count reflected above does include a small percentage of voters who are under 18 at present. Colorado law allows residents to register to vote as young as 16. Only active voters who are age 18 on or before Election Day will be mailed a ballot or able to vote.

To calculate voter turnout, excluding pre-registrants, or turnout by city or by party, review the return information provided here and compare using our Active Voter Registration Counts tool selecting voters 18 and older.
