Who's In the Race

Rep. Lauren Boebert (R-CO) faces Democrat Eileen Laubacher and Libertarian Douglas Mangeris in the November 3 general election in Colorado's 4th District. ​

Boebert has served as a U.S. representative for Colorado since 2021, and before Congress, she owned a gun-themed restaurant. She ran unopposed in the June 30 Republican primary. Laubacher is a retired U.S. Navy rear admiral who served 34 years, including as Special Assistant to the President, Senior Director for South Asia, and defense attaché to New Delhi. She also ran unopposed in the June 30 Democratic primary. Mangeris is a construction professional and blue-collar worker.

What They Stand For

Boebert has said she wants to grow the economy and make goods more affordable while opposing federal subsidies for wind and solar energy, according to Colorado Public Radio. She has also supported enforcing existing immigration laws and more deportations, saying people who entered illegally "should go back and wait in line," restricting Medicaid and Medicare to eligible recipients, and backing the Rural Health Transformation Program, passing a farm bill and an agriculture appropriations bill; and bipartisan solutions, saying restoring trust requires "doing the work," according to Colorado Public Radio.

Laubacher has proposed lowering costs by ending tariffs she says raise prices, cutting middle-class taxes, and cracking down on price gouging, according to her campaign website. She has also supported rural hospitals and telehealth, and allowing Medicaid to negotiate lower drug prices while capping insulin at $35 a month for everyone, term and age limits, banning congressional stock trading, and requiring transparency for political spending, a secure border and bipartisan immigration reform that creates a legal pathway for citizenship, and an "all-of-the-above" energy approach, with federal-land development shaped by local input, according to The Denver Post.

Mangeris has said his top issues are delivering water to rural Weld County, holding government officials accountable for every vote and dollar spent, and setting term limits, according to Colorado Public Radio.

The Money Behind the Race

Through June 30, Democrat Eileen Laubacher had raised about $10.35 million and had about $3.6 million on hand, while Republican incumbent Lauren Boebert had raised about $1.01 million and had about $247,000 on hand. As of June 30, Laubacher had nearly 14.6 times as much cash on hand as Boebert. No completed outside spending on either candidate reached the $10,000 threshold through the available reporting period.

Race Outlook: Ratings and Betting Markets

Despite Laubacher's commanding financial edge, every major forecaster rates the seat as safe or likely Republican. Cook Political Report rated the race Solid Republican as of Oct. 9; Sabato's Crystal Ball rated it Likely Republican as of Oct. 11; and Inside Elections rated it Solid Republican as of Oct. 2. Prediction-market traders on Kalshi gave Republicans a 73.53% chance of winning the seat as of Oct. 15, while Democrats stood at 26.47%.

The district's recent history helps explain the forecasters' confidence. Boebert won the seat in 2024 with about 54 percent of the vote. Before her, Republican Ken Buck carried the district in 2022 with about 61 percent. Colorado's eight U.S. House seats split five-to-three for Democrats in 2022 and four-to-four in 2024. Democrat Kamala Harris carried Colorado in the 2024 presidential election with about 54 percent of the vote. The 4th District's consistent Republican margins, even as the state went Democratic at the top of the ticket, underscore why money alone has not moved the race's outlook.
