Colorado uses a closed primary system, meaning voters are required to declare a party preference when registering to vote. The state does allow unaffiliated voters to choose to affiliate with a party on Election Day in order to vote.
To vote in Colorado, you must meet the following requirements:
- 18 years of age or older on the date of the election at which the person intends to vote,
- A citizen of the United States, and
- A resident of Colorado, as well as the intended voting precinct, 30 days immediately before the election at which the person intends to vote.
When and where
Colorado voters can register through election day, however the last day to register and still receive a ballot in the mail is 8 days prior to election day. You can register online here. You can also print off a paper registration form from the same website. The form must then be returned by fax, email, mail or in person.
As of October 2014, Colorado is one of the 15 states that have implemented online voter registration. Residents can register online at this website
The 2013 Colorado State Legislature passed a bill that authorizes same day registration. The bill makes other election reforms, including mailing a ballot to all registered voters and allowing in-person voting at any voting center established by the law instead of designated precinct polling places
