The Colorado primary election is Tuesday, June 30. Ballots were mailed to registered voters beginning June 8.

The recommended deadline to return a ballot by mail is June 22. Completed ballots must be received by county election officials no later than 7 p.m. on Election Day, June 30.

Voters have until July 8 to cure a signature discrepancy or resolve other ballot issues.

Who receives which ballot?

Voters affiliated with a major political party will receive a ballot containing candidates from their affiliated party and may vote only in that party’s primary.

Voters affiliated with a minor political party will receive a ballot containing candidates from their affiliated party and may vote only in that party’s primary.

Unaffiliated voters will receive both Democratic and Republican ballots. Unaffiliated voters may choose to vote in the Democratic, Republican or Unity Party primary, but they may cast a ballot in only one party’s primary election.

If an unaffiliated voter returns ballots for more than one political party, all ballots returned will be rejected, and none of the votes will be counted.

Unaffiliated voters may also vote in person at any Voter Service and Polling Center in their county and select the party ballot they wish to cast.

Check your voter registration status

Voters can verify their registration status, register to vote, or update their voter registration information online by entering their name, ZIP code, and date of birth.

What is the deadline to register to vote?

Colorado does not have a voter registration deadline. Eligible voters may register and vote up to and including Election Day. Registration is available until 7 p.m. on June 30 at a Voter Service and Polling Center.

Can you vote in person?

Yes. Voters who choose to vote in person must provide an acceptable form of identification, such as a Colorado driver’s license, U.S. passport, or another approved form of ID.

Voters can track the status of their ballot through BallotTrax.

Candidates on the ballots of Larimer County voters: Who’s running for what?

Federal Offices for Senate

Democratic Primary

  • John Hickenlooper — the incumbent U.S. senator, former governor of Colorado, and former mayor of Denver.
  • Julie Gonzales — a Denver state senator running as a progressive challenger to Hickenlooper.

Republican Primary

  • Mark Baisley — the only Republican candidate who qualified for the GOP primary ballot for U.S. Senate. Because he is unopposed, he is effectively the Republican nominee.

Federal Offices for the Second Congressional District

In Colorado’s 2nd Congressional District—which includes Estes Park, Larimer County west of I-25, Boulder County, and much of the mountain corridor—the 2026 primary ballot looks like this:

Democratic Primary

  • Joe Neguse —  the incumbent, a Boulder Democrat running unopposed for the Democratic nomination.

Republican Primary

  • Kelley Dennison — a Larimer County massage therapist whose campaign focuses on environmental conservation, public lands, immigration policy, and government accountability.
  • Christina Blunt — a Fort Collins small-business owner and hairdresser who has emphasized reducing government spending and applying private-sector management approaches to government.

State Offices

Governor’s Race

Gov. Jared Polis is term-limited and cannot seek a third consecutive term.

Democratic Primary

  • Michael Bennet — U.S. senator from Colorado.
  • Phil Weiser — Colorado attorney general.

Republican Primary

  • Scott Bottoms — State representative from Colorado Springs.
  • Barbara Kirkmeyer — State senator from Weld County.
  • Victor Marx — Author, speaker and ministry leader.

Secretary of State

For the 2026 Colorado Secretary of State race, the office is open because incumbent Secretary of State Jena Griswold is term-limited and cannot run again.

Democratic Primary

  • Amanda Gonzalez — Jefferson County Clerk and Recorder and former executive director of Colorado Common Cause.
  • Jessie Danielson — State senator from Wheat Ridge and former member of the Colorado House.

Republican Primary

  • James Wiley — Running unopposed for the Republican nomination and is effectively the GOP nominee.

State Treasurer

There is no contested primary on either side because each major party has only one candidate who qualified for the ballot. The office is open because Treasurer Dave Young is term-limited.

Democratic Nominee

  • Jeff Bridges — a state senator from Greenwood Village and vice chair of the Joint Budget Committee. He secured the Democratic nomination through the state assembly process, eliminating the need for a Democratic primary.

Republican Nominee

  • Kevin Grantham — a Fremont County commissioner and former president of the Colorado Senate. He is the sole Republican candidate and therefore became the GOP nominee without a primary contest.

Regent

For the University of Colorado Board of Regents, District 2, which includes Boulder, Larimer, and several mountain counties, including Estes Park, voters will see a contested Democratic primary and no Republican primary candidate on the June 30 ballot.

Democratic Primary

  • Edie Hooton
  • Kubs Lalchandani
  • Murray Smith

Republican Primary

  • No candidate

Larimer County Commissioner

For Larimer County Commissioner, only District 1 is on the 2026 ballot. The seat is open because incumbent Commissioner John Kefalas is not seeking reelection. District 1 includes northern Fort Collins, Laporte, Wellington, and the surrounding rural areas.

Democratic Primary

  • Shane Atkinson — legislative affairs coordinator in the Larimer County Manager’s Office, former teacher, and former constituent advocate for U.S. Rep. Joe Neguse. Atkinson is the only Democratic candidate who qualified for the primary ballot after other candidates failed to secure ballot access.

Republican Primary

  • No candidate

Colorado State Senate District 15

For Colorado State Senate District 15, which includes Estes Park and much of western Larimer County, there is no contested primary in 2026. For Estes Valley voters, the Marchman–Woodward race is expected to be one of the most closely watched legislative contests on the November ballot, pitting an incumbent Democrat against a well-known former Republican officeholder with strong name recognition in Larimer County.

Democratic Primary

  • Janice Marchman — the incumbent Democratic senator. She was elected to the seat in 2022 after previously serving on the Thompson School District Board of Education.

Democratic Primary

  • Rob Woodward — former state senator and former Larimer County commissioner. He previously represented Senate District 15 before being term-limited from the Senate and is seeking to return to the seat.

Other Larimer County offices on the ballot

“We in America do not have government by the majority. We have government by the majority who participate,” Thomas Jefferson is often credited with saying. That idea is especially important in down-ballot races — the contests for offices listed below the top race on a ballot. While presidential and statewide campaigns often draw the most attention, down-ballot races for county, municipal, school board, and special district offices can have the most direct effect on daily life. These elected officials help shape decisions about roads, public safety, schools, housing, taxes, health care, water, recreation, and other local services.
