Colorado Democrat Adam Frisch raised nearly $3.4 million in the third quarter this year for his bid to challenge Republican U.S. Rep. Lauren Boebert, his campaign announced Thursday.

Frisch’s total demolishes previous off-year fundraising records for Colorado congressional races and is close to the quarterly hauls reported this month by some leading U.S. Senate candidates running in swing states.

Frisch, a former Aspen city councilman, plans to report receiving more than 100,000 individual contributions for the three-month period ending Sept. 30, with the average donation falling under $32, his campaign said. He ended the quarter with more than $4.3 million in the bank.

Detailed reports covering the third quarter are due to the Federal Election Commission by Oct. 15. Boebert’s campaign has yet to release her fundraising totals for the period.

After coming within 546 votes of Boebert last year in the closest House race in the country, Frisch has turned in eye-popping fundraising numbers each quarter, including raising more than three times the receipts reported by Boebert for the second quarter.

Since launching his bid for a rematch in February, Frisch has raised just under $7.75 million, including the total announced Thursday – nearly as much as Boebert raised through the election last cycle and topping Frisch’s 2022 total receipts by more than $1 million.

Earlier this summer, the Cook Political Report moved the race into the toss-up column, citing Boebert’s close call in the last election, Frisch’s fundraising advantage and the incumbent’s continued combative approach to politics.

A poll released by Frisch’s campaign in August found Boebert and Frisch locked in a statistical tie among likely voters, with Frisch running 2 points ahead of the incumbent, within the survey’s margin of error.

“Western and Southern Colorado deserve a representative who will work hard to deliver results and put the needs of the district first, not an extreme political agenda,” Frisch said in a statement. “Thanks to our generous supporters, we will defeat Boebert in 2024.”

Boebert’s campaign manger, Drew Sexton, brushed aside Frisch’s fundraising announcement.

“As Aspen Adam continues to masquerade as a ‘businessman’, he’s going to need every one of those dollars to stave off his Democrat primary opponents who know he’s a phony,” Sexton told Colorado Politics in a text message. “He’ll eventually need to take a position on something outside of touting his quarterly ActBlue allowance and when he does, 3rd District voters won’t like what they hear.”

Boebert is serving her second term representing the sprawling, Republican-leaning 3rd Congressional District, which covers most of the Western Slope and parts of Southern Colorado, including Pueblo County and the San Luis Valley.

Both candidates have drawn primary opponents, and a slew of minor-party candidates are already running in the district.

Grand Junction Mayor Anna Stout declared this summer that she’s seeking the Democratic nomination, weeks before Grand Junction attorney Jeff Hurd jumped in the GOP primary. In addition, seasoned third-party candidate Gary Swing is hoping to run on the Unity Party ticket, Libertarian James Wiley is running for his party’s nomination and Mark Elworth Jr. – who briefly sought the Libertarian nomination – is running on the Legal Marijuana NOW Party ticket.

Once considered a swing district, Colorado’s 3rd CD hasn’t sent a Democrat to Washington since three-term U.S. Rep. John Salazar lost a bid for reelection in 2010 to Republican Scott Tipton. Boebert unseated Tipton in a GOP primary in 2020. Last year, Boebert easily survived a primary challenge from former state Sen. Don Coram, defeating the Montrose lawmaker by a nearly 30-point margin.
