(The Center Square) - Colorado’s 4th Congressional District race has yet to be decided, with U.S. Rep. Lauren Boebert, R-Windsor, falling less than 1% behind her Democratic challenger, Eileen Laubacher, as of late Tuesday afternoon. 

Laubacher has claimed victory, but Boebert hasn't conceded the close race. 

The Center Square reached out to both Boebert and Laubacher for comment, but they did not respond before publication.

Boebert has been at the nation’s capital since 2021, when she initially represented the 3rd Congressional District before districts were redrawn. Her term started after she won an upset victory in the 2020 election against a five-term Republican incumbent, Scott Tipton. 

In 2022, Boebert won again by a 546-vote margin against Democrat Adam Frisch, an Aspen City Council member. In 2024, she won against Democrat Trisha Calvarese with 53.6% of the vote. Calvarese had 42%.

As of 4 p.m. Mountain time on Tuesday, Laubacher, a 32-year retired Navy veteran and rear admiral, had 186,200 votes compared to Boebert’s 182,847 votes. 

Laubacher was registered as a Republican before switching to independent in 2024. She re-registered as a Democrat in 2025. She has focused her campaign on national security and government spending, but has disagreed with other Democrats who support Medicare for all and open borders. She called both ideas unfeasible.

Boebert has been a lifelong Republican who sided with President Donald Trump on numerous occasions. She called Trump's tariffs an "effective tool" during a debate in mid-October.

But Boebert expressed her dissatisfaction with the conflict with Iran and has acknowledged the rising costs of groceries, gas, and goods can be attributed to the conflict. 

Laubacher made massive strides against Boebert in political campaign contributions and spending. She brought in over $13 million in for her campaign alone, compared to Boebert’s $1.2 million. Most of Laubacher’s donations were less than $200 and came from individual donors across the state. 

On Monday, Laubacher took to her social media to claim she won the election. “This victory is historic. But making history means nothing if we don’t make a difference. My focus is simple: lower costs, protect healthcare, strengthen rural communities, take on corruption in both parties, and hold Washington accountable.” 

However, Boebert is not ready to give up just yet. She posted on her social media on Monday saying “Election week isn’t finished! Let’s finish counting every vote and hearing every voice before declaring anything.” 

Jack Todd, the Colorado Secretary of State’s Office's communications director, told The Center Square in an email that the post-election reporting will not be complete until Friday night. “As it stands, this race is outside of the mandatory recount threshold.”
