Pueblo Mayor Heather Graham, a Republican, on Monday endorsed Democratic nominee Adam Frisch in Colorado’s 3rd Congressional District, saying she’s confident Frisch will work across party lines to look out for the best interests of the city and its residents.

“Adam Frisch knows Pueblo and Pueblo knows him,” Graham said in a statement. “He has spent more than 130 days in Pueblo, and he knows we need a serious representative who is willing to set partisanship aside and work across the aisle to address the challenges our community faces.”

Frisch, a former Aspen City Council member, is facing Republican Jeff Hurd, a Grand Junction attorney making his first run for office, in the GOP-leaning 3rd CD, which covers most of the Western Slope and parts of Southern Colorado, including Pueblo County and the San Luis Valley.

Frisch was gearing up for a rematch with U.S. Rep. Lauren Boebert, the seat’s Republican incumbent, after coming within fewer than 600 votes of unseating Boebert two years ago. At the beginning of the year, however, she moved across the state to a safer district, and Hurd won the GOP nomination.

Graham, a restaurant owner who took office earlier this year — only the second elected mayor of the southern Colorado city in more than a century — said she was proud to endorse Frisch and looks forward to working with him if he’s elected to Congress.

“Adam will stand up for Pueblo’s working families, and he knows what it takes to get the job done,” she said. “Adam will turn down the temperature on our politics and stand up to help create jobs and look out for the working men and women of Pueblo.”

Noting that he’s spent more days campaigning in Pueblo than anywhere else in the sprawling district, Frisch welcomed Graham’s endorsement.

“This community needs better jobs, less crime and more opportunity, and that’s exactly what I’ll fight for in Congress,” Frisch said in a statement. “Mayor Graham has been an excellent leader for her community, and she and I are both on Team Pueblo above all else. I look forward to working alongside her to achieve our shared vision of a safer, more prosperous Pueblo.”

Graham told The Pueblo Chieftain she was impressed that Frisch had spent so much time on the ground learning about the city and its needs, including participating in multiple recent “ride-alongs” with the police department.

She contrasted the Democratic candidate’s interest and understanding with that of Boebert, who still represents the city in Congress, even though she’s running for another term in another congressional district.

Referring to Boebert, Graham told the Chieftain: “Our rep right now has pretty much disappeared and not had anything to do with Pueblo for quite some time.”

Hurd isn’t lacking in endorsements from his fellow Republicans, boasting a long list of supporters that reads like a Who’s Who of the GOP politicians who once held sway in Colorado. Among them are former Gov. Bill Owens, former U.S. Sen. Hank Brown and former U.S. Reps. Scott Tipton and Scott McInnes, the two Republicans who occupied the 3rd CD seat before Boebert.

Hurd also counts among his backers more than a dozen Republicans legislators, county commissioners and city council members, including Mark Aliff and Roger Gomez, the Pueblo City Council’s president and vice president, respectively.
