• In House District 6, Rep. Sean Camacho and civil rights attorney Iris Halpern are neck-and-neck

• In House District 9, Monica Van Buskirk leads by a wide margin against Neal Walia

Primary results for key Colorado House contests rolled in on Tuesday night, when voters chose who would carry their party’s banner into the November general election.

Turnout stood at 24% among the state’s four million active voters — meaning a relatively small share of the electorate decided the races, a common feature in primary elections.

The House currently holds a 43–22 Democratic majority, a balance not expected to shift dramatically this year. But Tuesday’s primaries will effectively settle the outcome in many safe districts long before November.

Nineteen of the 65 House seats on the ballot this fall will be decided by candidates who emerged from contested primaries.

Here are the unofficial results in key districts as of 8 p.m.

House District 6

The hottest race is happening in Denver’s House District 6, where Democratic candidates Rep. Sean Camacho and civil rights attorney Iris Halpern have been waging a heated contest in what’s expected to be a safe Democratic seat come November.

As of 8:30 p.m., Halpern, who initially trailed Camacho by 9 votes, now has a 363-vote lead over Camacho out of more than 16,000 ballots cast, based on unofficial results.

Independent expenditure committees have spent nearly $1 million on the contest, while Camacho has raised about $50,000 more for the race than Halpern.

Republican Kathleen Angel, a campus coordinator for Regis University, will face the primary winner in the November election.

House District 9

House District 9, which is in southeast Denver and a small portion of northern Arapahoe County, is an open seat that will be vacated by term-limited Rep. Emily Sirota, a Democrat, who is running for the state Senate.

Monica Van Buskirk, vice president of Partnerships for Stroke Onward, and Neal Walia, founder of Lotus Public Affairs, have raised nearly the same amount, leaving them closely matched in fundraising.

As of 8:30 p.m., Van Buskirk led Walia by more than 2,000 votes percentage points out of more than 9,000 votes cast, based on unofficial returns from the Denver Clerk and Recorder.

House District 5

House District 5 is currently represented by term-limited Rep. Alex Valdez, D-Denver. The district includes River North (RINO) and the area immediately west of the state Capitol, and based on the 2020 census, is about 34% Hispanic or Latino.

As of 8:30 p.m., Justine Sandoval has a commanding lead over Sterling Thomas Simms by more than 5,500 votes out of 10,000 votes cast, according to the Denver Clerk and Recorder. The winner will face off against Republican Johnnie Johnson in November.

House District 19

In House District 19, which includes parts of Boulder and Larimer counties, including Erie, Jillaire McMillan is trying again to unseat incumbent Rep. Dan Woog, a Republican.

But she first must get past Anil Pesaramelli, a software engineer for Kaiser Permanente and member of the Erie City Council, and Colton Jonjak Plahn.

McMillan led Pesaramelli by 19 percentage points and over Plahn by 34 percentage points, based on unofficial results. 

McMillan, an engineer and co-founder of a marine robotics company, lost a close contest in 2024 to Woog by 123 votes, after a recount. 

She’s raised more than $64,000 for Pesaramelli, who also lent his campaign $50,000. Plahn has raised just over $16,000 and loaned his campaign another $8,000.

Woog, who is running for his third term, is waiting in the wings for November’s contest.

House District 13

The race to succeed House Speaker Julie McCluskie in House District 13, which includes six central mountain counties, features Consuelo Redhorse, a community organizer and former Lake County municipal judge Chris Floyd.

Floyd led Redhorse by less than a half of a percentage point, based on unofficial results. 

Independent expenditure committees have also played an outsized role in this race, spending hundreds of thousands of dollars to support Floyd. 

Floyd has raised more than $41,000 to Redhorse’s $14,000. 

Former Lake County Assessor and Republican Miguel Martinez will meet the winner on the November ballot.

House District 14

Republican Rep. Ava Flanell, who won a vacancy contest last year to represent House District 14, is facing Troy Vanderhule, chief fundraising officer for Dobson Philanthropic, for the right to represent the north Colorado Springs district.

In central Colorado Springs-based House District 16, Rep. Rebecca Keltie, R-Colorado Springs, won the closest House race of the 2024 cycle, beating then-Rep. Stephanie Vigil by just three votes, a race decided by a recount.

Keltie isn’t coming back for a second term. The Republican primary for the open seat features former history teacher and D-11 school board member Jill Haffley against Jamie Koch, a practical government school coordinator for Charis Bible College. 

The Colorado Conservative Leadership Fund is backing Haffley, who has also raised more than $18,000 for her campaign to Koch’s $1,400.

Jackson has taken the lead over Keke by 9 percentage points, based on unofficial results.

The race has no Republican contender, so the primary winner will claim the seat once the results are certified.

While Keke has raised less than $33,000, Jackson has raised $89,000, and independent expenditure groups have spent heavily to support Keke. 

House District 42

In House District 42, Rep. Mandy Lindsay is running for her third term and faces a Democratic primary challenge for the Aurora seat from Sarah Woodson, who runs the nation’s first cannabis tourism and hospitality business. There is no Republican challenger in the district.

Parks has raised more than $38,000, while Rumfelt has raised $16,000. The bigger difference came in the support from independent expenditure committees. Colorado Conservative Leadership Fund, which is backing more traditional Republican candidates, has spent more than $235,000 to support Parks, while Rocky Mountain Gun Owners is supporting Rumfelt, although spending just over $1,500 in that effort.

House District 54

The last of the open seats is in the Western slope’s House District 54, which is held by term-limited Republican Rep. Matt Soper of Delta. 

The Republican primary features Jason Bias, who founded the Turning Point USA chapter at Mesa State University, and Nina Anderson, owner of Express Employment Professionals.

The winner faces Democrat Kathryn Kester Green in November.
