Democrat Eileen Laubacher defeated Republican Rep. Lauren Boebert in Colorado's 4th Congressional District, the Associated Press said Friday, according to Colorado Newsline and stations carrying the AP report^3,4,5,7,8.

The AP called the race at 12:53 p.m. Friday, when Laubacher had 48.8 percent of the vote and Boebert 47.9 percent, Newsline reported⁴. KHON2, carrying a report from The Hill, said Decision Desk HQ also projected Laubacher the winner, with Laubacher at 48.8 percent and Boebert at 47.8 percent with more than 95 percent of the vote counted⁶. CBS News also projected Laubacher the winner².

The 4th District covers most of Douglas County and Colorado's Eastern Plains and had been viewed as Republican-leaning^4,6. Decision Desk HQ had rated the seat likely Republican heading into Election Day, KHON2 reported⁶.

Laubacher is a retired Navy rear admiral running as a first-time candidate⁴. Newsline reported she was a longtime Republican who became a Democrat in 2024⁴. Boebert, first elected in the Western Slope's 3rd District, later moved and won the 4th District in 2024^4,6.

Laubacher had declared victory earlier in the week, Newsline said, while Boebert had not conceded before the AP call⁴. After the result, Boebert pointed to spending in the race, saying, "There's a lot of money dumped on my head"⁴. KHON2 said Federal Election Commission filings showed Laubacher raised millions more than Boebert⁶.

In a statement after she declared victory, Laubacher said her focus was "lower costs, protect healthcare, strengthen rural communities"⁴.

Newsline said two other Colorado House seats previously held by Republicans also flipped, and that with Boebert's loss the state's House delegation would favor Democrats 7-1⁴. Newsline, citing the AP, said about 99 percent of votes were counted at the call⁴. CBS News said more than a week after Election Day the votes in the district had been tallied². Certified statewide results were not in these accounts.
