How to participate in the June 30 primary
Colorado's primary election is Tuesday, June 30. Primaries determine which candidates each political party will place on the November general election ballot.
This year, the Democratic, Republican, Unity and Libertarian parties are holding primaries. You must be registered with one of these parties or as unaffiliated to participate. Registered party members will receive only their party’s ballot.
Unaffiliated voters were mailed both major party ballots (Democratic and Republican). They may vote and return only one. Unaffiliated voters can also choose to vote in either the Libertarian or Unity party primary, but additional steps are required. Visit Boulder County Elections' unaffiliated voter FAQ page for details.
Voting and returning your ballot
Ballots were mailed to eligible voters on June 8. If you did not receive your ballot, you can vote in person at a vote center. It is too late to have your ballot mailed to you.
Vote centers are open now through Election Day (closed Sunday). You can vote in person, register and vote on the same day, request a replacement ballot and more. The closest vote center to campus is located at 1750 33rd St., near Arapahoe.
If you still have your mail ballot, please return it to any 24‑hour drop box. It is too late to return ballots by mail. Ballots must be received or returned to a drop box by 7 p.m. on Election Day, Tuesday, June 30. You may return your ballot to any drop box in Colorado (for example, a Denver ballot returned in Boulder will be delivered to Denver for counting).
Interested voters can sign up for ballot processing center tours on Monday, June 29. Students are especially encouraged to attend.
For students
If you are a student and have questions regarding registration, please visit Boulder County’s student voting guidelines. On-campus students must have a residence hall mailing address and your mailbox number—you can find this information in your housing assignment confirmation email or in your MyCULiving portal.
