Lauren Boebert’s run in Congress is coming to an end after Democrat Eileen Laubacher flipped Colorado’s deeply conservative 4th Congressional District. CNN projected Laubacher as the winner Monday night once the remaining ballots could no longer erase her advantage, turning one of the country’s safest Republican seats into a startling Democratic pickup. Laubacher’s victory over Boebert followed nearly a week of counting in a race separated by only a few thousand votes.
Unofficial results showed Laubacher with roughly 48.8 percent of the vote to Boebert’s 47.9 percent, while Libertarian candidate Douglas Mangeris captured just over 3 percent. The final margin remained outside Colorado’s automatic-recount threshold, although the state permits candidates to request a recount after the statutory waiting period. Overseas military and absentee ballots postmarked by Election Day could still be received through November 12. The latest published tabulation lists Laubacher ahead by more than 3,000 votes.
The result is especially consequential because Colorado’s 4th District has long been considered the state’s most reliably Republican congressional seat. Laubacher’s strength came from more populous parts of the district, including Larimer, Douglas and Arapahoe counties, while Boebert maintained an advantage across much of rural Colorado, including Weld County. That geographic split turned what normally would have been a comfortable Republican hold into a close contest decided by suburban and exurban voters.
Laubacher, a retired U.S. Navy rear admiral, built her campaign around an unusually large effort for a Democratic challenger in the district. She reportedly traveled tens of thousands of miles while meeting voters throughout the sprawling constituency, and her campaign’s fundraising substantially outpaced Boebert’s during the race. Colorado Public Radio’s campaign profile described Laubacher’s extensive organizing operation and her attempt to compete in territory Democrats have rarely threatened.
For Boebert, the defeat caps a turbulent path through Colorado politics. After narrowly surviving a 2022 reelection fight in her former district, she moved to the 4th District and won the seat in 2024. The switch placed her in a much more Republican constituency, but it also made the district a national stage for her combative brand of conservative politics. Her loss now removes one of the most recognizable MAGA personalities from the House while giving Democrats an unexpected foothold in Colorado’s congressional delegation.
Laubacher is expected to take office in January, pending certification of the results and the resolution of any recount request. The immediate political question is whether her victory represents a durable shift or a one-cycle backlash against a polarizing incumbent. Either way, the race demonstrates that even a district long treated as safely Republican can become competitive when turnout, candidate quality and changing suburban coalitions align.
