In Colorado, individuals only lose their voting eligibility while they are actively serving a sentence of confinement for a felony conviction. Eligibility to vote is automatically restored once an individual has completed their full term of imprisonment, at which time the individual may register or re-register to vote. Individuals serving misdemeanor sentences, in pre-trial detention, on probation/parole, or with prior criminal records are all eligible to vote. Voters with Convictions FAQs
