Democrat Eileen Laubacher defeated Republican incumbent Lauren Boebert in Colorado’s fourth congressional district race, according to the Associated Press.
The victory changes the political makeup of a district that has long served as a Republican stronghold on Colorado's eastern plains. Laubacher, a retired two-star navy rear admiral, secured the seat with a margin of less than 1%.
“I’m honored by the trust the people of Colorado’s fourth district have placed in me,” Laubacher said in a statement. “This campaign was never about party labels. It was about putting people first.”
The narrow margin concludes a campaign defined by personal controversies and questions regarding political residency. Boebert, a three-term representative and prominent MAGA figure, faced scrutiny for her 2024 move to the district after a narrow victory in her previous seat.
Laubacher, who became a registered Democrat in 2025, campaigned on her background in military and national security service. During a debate, she characterized the Republican party as having become “nearly unrecognizable.”

A campaign of personal and political friction
The race was marked by frequent exchanges regarding the motivations of both candidates. Boebert accused Laubacher of moving to the district specifically to run for the seat, while Boebert herself faced criticism for her own recent relocation.
Boebert framed the politics of the region as a battle against outside influence, claiming that "dark money" from Hollywood was attempting to "steal" congressional seats. She specifically cited donations from figures such as Barbra Streisand and Ryan Reynolds as evidence of Hollywood’s attempt to buy influence in Congress.
Laubacher’s victory also follows a turbulent tenure for Boebert, which included several high-profile incidents. In 2023, Boebert became the subject of viral footage showing her vaping and being escorted out of a musical in Denver. She later apologized for the incident, which coincided with her divorce from her husband.
Just weeks before voters headed to the polls, Boebert faced an ethics complaint involving allegations of sexual relationships with three staffers and payments made to ensure silence. Boebert has denied these allegations, calling them “politically motivated.”
Suzan DelBene, chair of the Democratic Congressional Campaign Committee, commented on the result by stating, “Lauren Boebert’s sideshow is over.”
Tensions within the Republican party
While Boebert remained a loyalist to Donald Trump, the relationship between the two was not without friction. Boebert occasionally broke with the former president, most notably when she advocated for the release of the Epstein files despite pressure from the White House.
This stance drew criticism from Trump, who referred to Boebert as a “carpetbagger” and “dumb.” The tension escalated when the president used his first veto of his second term to block a bill sponsored by Boebert that would have funded a critical drinking water project for the district.

The veto impacted approximately 50,000 people in southeast Colorado. Boebert reacted to the decision by stating, “Nothing says ‘America First’ like denying clean drinking water to 50,000 people in south-east Colorado many of whom enthusiastically voted for him all three elections.”
“If this administration wants to make its legacy blocking projects that deliver water to rural Americans; that’s on them,” Boebert said.
The outcome in the fourth district suggests a complex electorate that, while conservative, was willing to pivot toward a candidate with a background in national security and military service. Laubacher addressed both sides of the aisle in her post-election remarks, promising to fight for all constituents regardless of their vote.
“To those who voted for me, thank you, I will strive to make you proud. To those who didn’t, I’ll fight just as hard for you and hope to earn your support,” Laubacher said.
