Laubacher, a retired Navy admiral who served in the military for more than 30 years, said she entered the race out of alarm about the direction of the country. "I have never felt as much of a threat to our country, our Constitution, our very democracy, as I do at this time," she said.

Her victory unseats one of President Donald Trump's most outspoken allies in Congress. Boebert has represented the 4th District since 2025. She previously held the state's 3rd Congressional District but switched districts in late 2023, saying she needed a "fresh start following a difficult year" that included family turmoil and several controversies.

The race drew national attention as a test of Boebert's enduring appeal in a district she chose after leaving her previous seat. Laubacher's military background and focus on democratic institutions resonated with voters in a contest that took days to resolve.

Laubacher is set to join the new Congress after attending orientation for incoming members in Washington. Her win adds a prominent Democratic voice to Colorado's delegation and removes a high-profile Republican from the House.
