CNN projects Democrat Eileen Laubacher to win Colorado's 4th District seat

CNN's Decision Desk projects that Democrat Eileen Laubacher, a retired rear admiral, will win Colorado's 4th congressional district, ending the tenure of incumbent Republican Rep. Lauren Boebert.

Laubacher, who served more than three decades in the Navy, emphasized affordability issues in her campaign and benefited from broader national trends that have been challenging for the GOP.

Boerbert, who was first elected in 2020 after defeating a long-time Republican incumbent in a primary, had previously run in a more conservative district to improve her electoral prospects. She had secured a fourth term in 2024 with an 11-point margin but faced a narrow victory in 2022, winning by only 546 votes.

President Donald Trump endorsed Boebert shortly before the election, describing her as a long-time supporter. Boebert has previously collaborated with both Republican and Democratic lawmakers on issues such as the release of Jeffrey Epstein case files, which drew criticism from some GOP leaders.

If the projection holds, Laubacher's victory would flip the seat to the Democratic Party.
