I’m running for governor to turn bold ideas into real results for you and your family. Together, we can make Colorado completely energy independent and 100% renewable by 2040. We can bring free, full-day kindergarten and preschool to every community in our state. And we can build an inclusive economy where employees at all levels make more, not just CEOs.

What is the difference between a primary and a general election?

The State of Colorado holds regularly scheduled state elections every two years; a state Primary Election in June and a General election in November. The nominated candidates from each party’s primary ballot will be placed on the November General Election ballot. The winner of the November General Election will hold office.

Who is eligible to vote in a Primary Election?

You can vote in the Primary Election if you are 18 years old, a US citizen, and a Colorado resident.

I am an unaffiliated voter, can I vote in the Primary?

Yes! For the first time in Colorado unaffiliated voters can participate in a major party’s primary election. In order for your vote to count, you must choose one party to vote for.

I am an unaffiliated voter. Do I have to choose in advance which party’s primary ballot to vote?

No, but you can if you want to. You have several options:

  1. You may choose which party’s ballot you want to get in the mail for the next primary election by selecting a party preference at or on any paper voter registration form.
  2.  If you would rather receive a packet containing the ballots of all participating major parties, you can take no action or select this option when first registering to vote.
  3. You can also appear in person at any Voter Service and Polling Center in your county and choose the party’s ballot you want to vote. 

Does selecting a ballot preference as an unaffiliated voter mean that I am joining that party?

No. An unaffiliated voter who selects a ballot preference in advance of a primary election will remain unaffiliated. 

Does voting in a party’s primary as an unaffiliated voter mean that I am joining that party?

No. An unaffiliated voter who votes in a party’s primary will remain unaffiliated. However, the primary that you vote in will be a public record (but not how you voted).

I am an unaffiliated voter and received a Democratic and Republican ballot. Can I turn them both in?

Unaffiliated voters may only return one party’s ballot. Returning two voted ballots will result in neither ballot counting.

What should I do if I do not receive my mail ballot or make a mistake, damage, or lose my mail ballot?

You may request a replacement mail ballot from your county clerk. You may also vote in-person at a voter service and polling center in the county that you are registered to vote in.

How do I get my ballot?

Every voter now receives a mail ballot at the mailing address provided through their voter registration file. To check the address on file for your voter registration visit:

If you would like to vote at the polls, you can surrender your mail ballot and vote in-person at a voter service and polling center. To do so, find your polling location: 

How do I know if my mail ballot has been mailed?

You can go to to check the status of your ballot. Log into your voter record, which will show whether your mail ballot has been sent. If you have more questions about the status of your mail ballot, please contact your county clerk and recorder.

Where can I turn in my ballot?

In Colorado, you have a few options on how to vote! You can either mail your ballot back by using adequate postage, turn it in to a Ballot Drop Box, or take it to a Voter Service and Polling Center in the county that you’re registered in!

Will my mail ballot be counted? I heard that mail ballots might not be counted.

Every valid mail ballot is counted. Be sure to sign the envelope when you return your mail ballot. Your county clerk must receive your ballot no later than 7:00 PM on Election Day. If you are not sure if your ballot will arrive in time, drop it off in person. 


Contact your  county clerk and recorder for drop-off locations.If you recently registered for the first time, you may need to provide a copy of your ID along with your mail ballot. Your county clerk will have provided instructions about the ID requirement along with your ballot.

If I am voting by mail, when must the county clerk and recorder receive my ballot?

If you plan to mail your ballot back, send it in no later than June 18. Mail ballots must be received by the county clerk and recorder no later than 7:00 PM on Election Day, postmarks do not count.  If you do not mail your ballot by June 18, please turn in your ballot at a drop box or a Voter Service and Polling Center.
