Monday, Feb. 24, is the last day for Colorado voters to request a mail ballot be sent to them. After this date, you can register and/or vote in person.

Did you get your ballot?

The Colorado presidential primary is March 3, but ballots were mailed to eligible voters beginning Feb 10. Check your voter registration if you recently moved, and/or get registered today!

What to do if you haven’t received your ballot

Search for your voter registration record online. If there is no record, register to vote with a Colorado ID/driver’s license. If you’re already registered, check your mailing address. If you update your address, a new ballot will automatically be sent to you (and any ballots previously mailed will be voided). See special instructions for listing on-campus addresses.

If your address is correct, you will need to contact your clerk and recorder’s office to request a replacement mail ballot. Boulder County voters can call the elections office at 303-413-7740. Colorado voters registered outside of Boulder county should contact their county clerk and recorder office.

Who can vote?

Only voters who are registered as either a Democrat, Republican or unaffiliated can vote in presidential primaries in Colorado. Registered Democrats/Republicans will receive only the ballot for their party. Unaffiliated voters will be mailed both party ballots (unless you pre-selected your preference) but can only vote and return one. 

There is no registration deadline. You can register and vote up to and including Election Day. See student voting guidelines and registration requirements.

New this year

Seventeen-year-olds who will turn 18 by the general election, Nov. 3, can now vote in primaries in Colorado!

Register to vote, check your registration

If you plan to vote in Colorado (either in Boulder or your home county), please register to vote or check your registration.

Feb. 24 is the last date to register/update your registration and still be mailed a ballot. After that, you will need to go to a Voter Service Center to register and vote in person. There will be a Voter Service Center in the UMC beginning Monday, Feb. 24, and students may use their Buff OneCards to register and vote.

Students living on campus

Boulder County Elections has a specific way you must list your on-campus address on your voter registration record in order to get your mail ballot. Visit the Boulder County Student Voting Guidelines page for more details.

Cast your ballot

Simply drop off your mail ballot on campus at the 24-hour dropoff box at the UMC. This box may be used by any Colorado voter—out-of-county ballots will be rerouted to the correct county.
