Eligibility
In order to register to vote, you must be a U.S. citizen and have residency in Colorado at least 22 days prior to Election Day.
- You can register to vote if you are at least 16 years old, but can only vote if you will be 18 by Election Day.
- In Colorado, those convicted of a felony are disenfranchised only as long as they are incarcerated; those on parole, probation, or with unpaid restitution and fines regain their right to vote.
- Colorado’s Secretary of State’s website states: “For the purposes of registering to vote and voting, no person may gain residence because of their presence in Colorado. Likewise, persons may not lose residence because of their absence while in military service or while a student at any institution of higher education.” Out-of-state students attending college in Colorado may, therefore, experience difficulties claiming Colorado residency.
Deadline
Colorado has same-day voter registration, meaning that you are able to register to vote up until the date of the election (November 2, 2021).
