Voting Information for Colorado
Don’t miss your next election!
Colorado is a vote-by-mail state. As long as your registration lists your current address, you will receive a ballot. If you have moved, please be sure to update your registration at least 8 days before the next election to receive a ballot by-mail. (Click here to register to vote.) You may go to your local elections office and designated polling centers to register to vote in-person through election day.
Colorado holds semi-closed primaries. Voters must be registered with their party of choice or unafilliated with a party. When registering, unaffiliated voters can select to receive ballots from all parties by mail and later decide which ballot to use and return.
Some congressional seats, state offices and constitutional amendments may be included on the ballot.Find Your Representatives
