The Shifting Landscape of Colorado’s 4th District
The political map of Colorado looks fundamentally different this morning.
Democrat Eileen Laubacher declared victory on Monday in the race for the 4th Congressional District, signaling a potential end to the tenure of U.S. Rep. Lauren Boebert. While the Associated Press has yet to formally call the contest, CNN projected a Laubacher win as the candidate arrived in Washington, D.C., for new member orientation.
The stakes here are high for both parties. The 4th District has long served as a stronghold for the GOP, having elected a Democrat only once in the last 53 years. According to reporting by The Denver Post, Laubacher currently holds a lead of 48.8% to 47.9%, a margin of less than one percentage point. This gap is wide enough to avoid an automatic recount, though the race remains technically unfinalized.
Boebert’s Path to Contestation
Incumbent Lauren Boebert has not conceded, pointing to remaining ballots that are yet to be processed or cured for signature discrepancies. In a video address shared on social media Monday evening, Boebert likened the premature victory declaration to “icing a cake before it comes out of the oven.”
Her campaign attorney, Scott Gessler, previously stated the team is investigating what they described as “unusual voting patterns,” though no specific evidence has been provided to support claims of irregularities.

The tension in the district is palpable. As Denver7 reported, state law allows for the counting of military and overseas ballots to continue through November 13, leaving a narrow window for the final tally to shift.
Boebert, who previously represented the 3rd District before relocating to the 4th, has faced a complex relationship with the national party, including a recent, albeit late, endorsement from President Donald Trump after a period of public friction.
A New Political Calculus
Laubacher’s campaign strategy centered on a moderate, listening-first approach. A former Republican who transitioned to the Democratic Party, she has distanced herself from the more progressive wing of her new caucus.
“The way we won this race is the way I intend to continue serving the people, which is going everywhere, talking a little bit and listening a lot,” Laubacher told The Denver Post. She has expressed interest in bipartisan cooperation on issues ranging from tariff policy to anti-corruption measures.

The race was also affected by the presence of Libertarian candidate Doug Mangeris. With over 12,600 votes cast for Mangeris, his performance significantly exceeds the 3,352-vote margin between the two primary candidates. This mirrors the 2022 election cycle in Colorado’s 8th District, where observers noted that third-party candidates can fundamentally alter the outcome of tight congressional contests.
Looking Toward the Capitol
Laubacher’s presence at the Capitol for orientation, even while ballots are still being counted, is not without precedent. In 2022, Adam Frisch attended the same sessions while trailing Boebert in a race that remained in limbo.
For the constituents of the 4th District, the result represents a historic shift in representation. Whether this transition holds firm once the final military and overseas ballots are cleared remains the central question of the week.

The broader context of this race is the national “blue wave” that impacted several Colorado seats, including the 8th District where Manny Rutinel defeated incumbent Gabe Evans, and the 5th District where Jessica Killin secured victory over Jeff Crank.
As officials continue to process the final smattering of ballots, the 4th District serves as a focal point for the changing political identity of Colorado’s Eastern Plains and suburban metro regions.
