Your complete 2026 Douglas County ballot: every race from governor to commissioner

If you registered the words "midterm election" and tuned out, here's the part worth your attention: a Douglas County ballot in 2026 runs from the governor's office all the way down to who runs the county. And for a lot of these races, the decision isn't in November. It's in the June 30 primary, which in a county that still leans Republican often settles the contest months early. Here's the whole ballot, top to bottom, and where the real fights are.

First, the mechanics

Colorado mails a ballot to every active registered voter. Primary ballots go out in early June, and yours has to be received by 7 p.m. June 30 (the general is November 3). Colorado runs a semi-open primary: if you're unaffiliated (now the largest bloc in Douglas County), you'll get both parties' primary ballots but may vote only one. Return both and neither counts. One caveat: this is the field as of late June, before the primary locks the nominees. For your exact, address-specific ballot, Douglas County Elections is the source of truth.

The top of the ticket (statewide)

Every Coloradan votes on these. Douglas County leans red; the state leans blue. That tension runs under all of them.

Governor: open seat

Jared Polis is term-limited.

• Democratic primary: U.S. Sen. Michael Bennet vs. Attorney General Phil Weiser, a heavyweight matchup.
• Republican primary: state Sen. Barb Kirkmeyer (establishment lane), state Rep. Scott Bottoms, and ministry leader Victor Marx.

U.S. Senate

Incumbent Democrat John Hickenlooper is running for a second term.

• Democratic primary: Hickenlooper vs. progressive state Sen. Julie Gonzales.
• Republican: state Sen. Mark Baisley, presumptive nominee. And, relevant to us, he's vacating a Douglas County senate seat to run (more below).

Attorney General: open seat

• Democratic primary: a crowded field led by Secretary of State Jena Griswold, Boulder DA Michael Dougherty, ex-DOJ antitrust official Hetal Doshi, and workers'-rights attorney David Seligman.
• Republican primary: El Paso County DA Michael Allen vs. David Willson.

Secretary of State: open seat

Griswold is term-limited.

• Democratic primary: state Sen. Jessie Danielson vs. Jefferson County Clerk Amanda Gonzalez.
• Republican: James Wiley, unopposed (the other filers did not make the certified ballot).

Treasurer: open seat

• Democratic: state Sen. Jeff Bridges, unopposed (Titone, DiTullio, and Mikos did not make the certified ballot).
• Republican: former Senate President Kevin Grantham, unopposed.

Congress

Geography matters here: almost the entire county sits in the 4th Congressional District. Only a sliver of Littleton on the northwest edge falls into the 6th. For nearly every reader, CD-4 is your race.

CO-04 (you, almost certainly)

Incumbent Lauren Boebert (R), who moved over from CO-03 in 2024, is running again.

• Republican: Lauren Boebert, unopposed (Eric Phelan and Eric San Felipe did not make the certified ballot).
• Democratic: retired Navy rear admiral Eileen Laubacher is the printed nominee. Jenna Preston is a certified write-in, and John Padora did not make the printed ballot.

CO-06 (the Littleton sliver only)

Incumbent Jason Crow (D) faces primary challengers Travis Dishon and Dylan Shelby; Republican Khaleb Dammen is unopposed to face him.

The statehouse: where DougCo actually splits up

Your state legislators are the most local partisan races, and the county is carved into two senate districts and four house districts. One of the only contested *local* primaries lives here.

State Senate

• SD-4: open seat. Covers most of the county (Castle Rock, Parker, Castle Pines, Larkspur, The Pinery). Baisley's Senate run leaves it open. Republican Teddy Collins and Democrat Justin Kurth are each unopposed in the primary (Kevin Conrad and Jennifer James did not make the certified ballot), so the seat is settled in November.
• SD-30: the marquee general (Highlands Ranch / Lone Tree). The county's genuine swing seat (Harris carried it by roughly 2 points in 2024). Appointed incumbent John Carson (R) vs. Democrat Kevin Leung, both unopposed in the primary, a real November fight.

State House

All four are set for November except HD-44:

• HD-39 (Highlands Ranch / Lone Tree): Incumbent Brandi Bradley (R) vs. Democrat Christian Schilder, both unopposed in the primary (challenger Deborah Mulvey did not make the certified ballot).
• HD-43 (Highlands Ranch): swing seat. One of the few Democrat-held DougCo seats: retired Marine Bob Marshall (D) vs. Republican Nate Marsh. Watch this one.
• HD-44 (Parker): contested R primary. Incumbent Anthony Hartsook (R) vs. challenger Bob Davis, a retired police officer nominated from the assembly floor; Democrat Egan Bowness awaits in November.
• HD-45 (Castle Rock / The Pinery): incumbent Max Brooks (R) vs. Democrat Michael Clarkson.

The county

The one purely local partisan race is the District 1 commissioner seat (Parker / north county), open because Abe Laydon is term-limited. It comes down to a June 30 Republican primary between Parker councilman John Diak and Jake Bockenfeld, with Democrat Irene Bonham waiting in November. We broke that race down in detail in our District 1 commissioner deep dive; it's the most consequential local vote on your ballot. The other county offices (sheriff, clerk, assessor, the new 23rd Judicial District DA) were on the 2024 ballot and aren't up again until 2028.

What's not on the ballot yet, but might be

A few big questions are still fighting to qualify for November; none are official as of late June:

• Expanding the county commission from 3 to 5. A citizen petition needs 15,046 valid signatures by August 1; organizers were roughly a third of the way there in early summer. If it qualifies, you'd also choose *how* a bigger board gets elected (five districts, or three districts plus two at-large).
• A Douglas County School District mill levy override (around $50 million for teacher pay and programming). The board has signaled interest but hasn't formally placed it yet.
• Statewide citizen initiatives on immigration enforcement, fentanyl and trafficking penalties, and transgender-related questions are circulating, but won't be confirmed until signatures are verified after the August 3 deadline.
• Judicial retention: you'll also get yes/no votes on retaining several state appellate judges and local 23rd Judicial District judges. The roster posts closer to the election.

Bottom line

Two dates: June 30 and November 3. The thing to understand about a county like this: the primary is where most races are actually decided. The contested ones this cycle are the HD-44 Republican primary and the District 1 commissioner race. If you're unaffiliated, you get to weigh in on one party's primary, so don't leave it on the counter. For your exact ballot and drop-box locations, go to Douglas County Elections.
