Unaffiliated voters in Colorado primaries
The June 26, 2018, primaries were the first chance that Colorado voters unaffiliated with either major party had to participate in partisan primaries. The state's 1.1 million unaffiliated voters received mail-in ballots from their county clerks and were not able to opt out of receiving a ballot. If a voter did not request a ballot from one party, she or he received ballots for both parties. Voters could only complete a ballot for one party's primary. If the voter completed both party ballots, the ballots were invalidated.
County officials recommended that voters mail their ballots in by June 16. If voters chose to drop their ballots off at their county election offices, they had until 7:00 PM MT on June 26.[3]
This change in the voting system came from Proposition 108, a 2016 initiated state statute approved by 53.3 percent of voters. Prior to the passage of Proposition 108, Colorado utilized a closed primary system where only voters registered with a political party could participate. Unaffiliated voters were able to affiliate with one of the parties on election day if they chose.

Voter information
How the primary works
A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election.
Colorado utilizes a semi-closed primary system. According to Section 1-7-201 of the Colorado Revised Statutes, "An eligible unaffiliated elector, including a preregistrant who is eligible under section 1-2-101 (2)(c), is entitled to vote in the primary election of a major political party without affiliating with that political party."[5][6]
For information about which offices are nominated via primary election, see this article.
Poll times
In Colorado, polls are open from 7:00 a.m. to 7:00 p.m. local time for those who choose to vote in person rather than by mail. An individual who is in line at the time polls close must be allowed to vote.[7][8]
Registration requirements
- Check your voter registration status here.
In Colorado, an individual can pre-register to vote if they are at least 15 years old. Voters must be at least 18 years old to vote in any election. A voter must be a citizen of the United States and have established residence in Colorado to vote.[9]
Colorado voters can register to vote through Election Day. However, in order to automatically receive a absentee/mail-in ballot, a voter must register online, through the mail, at a voter registration agency, or driver's license examination facility at least eight days prior to Election Day. A voter that registers through a voter registration drive must submit their application no later than 22 days before the election to automatically receive an absentee/mail-in ballot. A voter can register online or submit a form in person or by fax, email, or mail.[9][10][11]
Automatic registration

Colorado automatically registers eligible individuals to vote through the Department of Motor Vehicles and certain other state agencies.
Online registration
- See also: Online voter registration
Colorado has implemented an online voter registration system. Residents can register to vote by visiting this website.
Same-day registration
- See also: Same-day voter registration
Colorado allows same-day voter registration for individuals who vote in person.
Residency requirements
Colorado law requires 22 days of residency in the state before a person may vote.[10]
Verification of citizenship
Colorado does not require proof of citizenship for voter registration. An individual applying to register to vote must attest that they are a U.S. citizen under penalty of perjury.
All 49 states with voter registration systems require applicants to declare that they are U.S. citizens in order to register to vote in state and federal elections, under penalty of perjury or other punishment.[12] Seven states — Alabama, Arizona, Georgia, Kansas, Louisiana, New Hampshire, and Wyoming — have laws requiring verification of citizenship at the time of voter registration, whether in effect or not. In three states — California, Maryland, and Vermont — at least one local jurisdiction allows noncitizens to vote in some local elections. Noncitizens registering to vote in those elections must complete a voter registration application provided by the local jurisdiction and are not eligible to register as state or federal voters.
Verifying your registration
The site Go Vote Colorado, run by the Colorado Secretary of State office, allows residents to check their voter registration status online.
Voter ID requirements
Colorado requires voters to present non-photo identification when voting in person. If voting by mail for the first, a voter may also need to return a photocopy of his or her identification with their mail-in ballot. Click here for more information.

- Note: SB 1, signed into law on May 12, 2025, specified that tribal IDs issued by the Bureau of Indian Affairs, the Indian Health Service, or another federal agency were also valid identification.
Early and absentee voting
Colorado conducts what are commonly referred to as all-mail elections. In Colorado, voting is conducted primarily, although not necessarily exclusively, by mail. Election officials automatically distribute mail-in ballots to active electors starting 18 to 22 days before an election. Colorado law requires county clerks to operate polling locations (Voter Service and Polling Centers, or VSPCs) starting 15 days before an election and continuing through Election Day, excluding Sundays. At these locations, eligible voters can do any of the following:[15]
- void their mail-in ballots to vote in person,
- register to vote,
- update existing voter registration records,
- obtain mail-in ballots, or
- vote in person via paper ballots or accessible voting devices.

- ↑ Under federal law, the national mail voter registration application (a version of which is in use in all states with voter registration systems) requires applicants to indicate that they are U.S. citizens in order to complete an application to vote in state or federal elections, but does not require voters to provide documentary proof of citizenship. According to the U.S. Department of Justice, the application "may require only the minimum amount of information necessary to prevent duplicate voter registrations and permit State officials both to determine the eligibility of the applicant to vote and to administer the voting process."
