Democrat Eileen Laubacher Unseats Lauren Boebert In Colorado House Race
Democrat Eileen Laubacher has unseated Republican Rep. Lauren Boebert in Colorado's 4th Congressional District, a solidly GOP seat, with networks confirming the upset on Friday, November 13, 10 days after Election Day.[1]
CBS News projected Laubacher the winner by about 1 percentage point once all ballots were counted, finalizing one of the cycle's most closely watched House races and cementing Democrats' newly won majority in the incoming 120th Congress.[2] Laubacher, who has already attended new member orientation in Washington this week, will represent a district that Republicans carried by more than 18 points just two years ago, underscoring the scale of Boebert's loss and the broader GOP setback.[1]
Laubacher is a retired two-star Navy rear admiral who served on President Biden's National Security Council, lives in the Denver suburb of Highlands Ranch, and previously was a registered Republican before switching parties, a biography Democrats highlighted to court moderate voters in the conservative-leaning district.[2] Colorado's 4th District covers the state's eastern third as well as fast-growing suburban areas in Douglas County and parts of Loveland, a mix of rural and exurban communities that had made it a cornerstone of the GOP's Colorado map.[2]
Boebert, a three-term Republican incumbent and fixture in conservative media, shifted from Colorado's more competitive 3rd District to the 4th in 2024 after narrowly surviving a challenge there, then won her new seat with 53.6% of the vote that year as Republicans carried the district by more than 18 points.[1][2] The move was widely seen as an effort to secure a safer political foothold, which makes her defeat in 2026 especially striking for a party that once counted the area among its most reliable strongholds.[1]
The race unfolded against a difficult national environment for Republicans, as Democrats flipped both the House and Senate and Boebert herself publicly lamented her party's performance, saying after the election that "we collectively failed" and that voters signaled "we have failed in this governing experience for this Congress."[1] In the campaign's final stretch, Boebert also faced unwelcome personal headlines, including a Weld County judge's decision to grant her a temporary protection order against David Wheeler, who accused her of improper sexual relationships with staff and a $200,000 hush payment, allegations she has denied.[2]
