In Colorado's 3rd Congressional District, a rural region that spans much of the southwestern part of the state, some people voted for Republican Lauren Boebert two years ago.

Boebert's surprisingly close race against Adam Frisch, a former Aspen city councilman, has become one of the most closely watched races in the country.

Frisch was behind Boebert in the U.S. House race. Ahead of Tuesday's election, the district was rated solidly Republican by the Cook Political Report. Trump captured 53.1% of the vote in the district in 2016 and 52.9% in the 2014–2018.

As control of the House hangs in the balance, the results of the Boebert-Frisch battle are likely to lead to a recount. An automatic recount is required if the margin of victory is less than or equal to 1% of the votes cast. Losing candidates can ask for a recount at their own expense.

Apple said she usually votes Republican but not this year.

She's a mini Trump. When asked why she changed her vote this time, she said that it was a turn off. "Boebert wanted to create jobs at the expense of the natural beauty and landscape of the Rockies," she said.

Boebert wasn't reachable for comment Friday.

Frisch has gotten this far by running a steady campaign as a moderate Democrat who spoke out against President Joe Biden's policies, getting a head start on raising money, and taking advantage of a Republican incumbent who turned some voters off.

Frisch wasn't given much of a chance to win, according to a Colorado-based Democratic political consultant. He did this alone.

Boebert, who was voted into office after besting five-term incumbent Scott Tipton in the 2020 primary, has helped Frisch by being an ardent Trump supporter and one of Congress' most conservative members.

She caused an uproar when she claimed she was allowed to carry a gun in the Capitol after the riot.

Political experts say that Boebert has become a volatile figure within her district, opening the door for Frisch to win the seat.

She wanted to be a television star.

Frisch said on MSNBC that the race's close is due to citizens' frustration.

He said that the current representative has hurt the country. The current representative has hurt our veterans. Two years have passed since our district was ignored while she was on a circus.

He promised to improve medical care for military veterans, protect natural resources and support abortion rights.

Frisch believes that women should have the freedom to choose what is best for them and their families.

According to a political science professor at the University of Denver, his plan to stay competitive in the congressional race has worked.

He said a lot of this is about Boebert. She has been trying to draw attention to herself. Republicans may have lost a seat because of her style.

Nicholas Donaldson said he turned on Boebert after she was elected.

Donaldson believes that she has neglected the district and failed to help veterans. She has acted childish and not gotten anything done.

If she is re-elected, he thinks her divisive speech and pushing of conspiracy theories could lead to violence.

Betty said she would have voted for anyone who ran against Boebert.

Boebert was leading as the final votes were being counted.

An associate political science professor at the University of Colorado said that it would be a recount situation. It is so close and tight that no one expected it to be.
