The Democrat running to unseat U.S. Rep. Lauren Boebert has pulled within 2 percentage points of the Republican incumbent in Colorado’s 3rd Congressional District, putting the candidates in a statistical tie only weeks before voting begins in the state, according to an internal poll released Tuesday by Boebert’s challenger.

The poll of likely voters, conducted for former Aspen City Councilman Adam Frisch’s campaign by Keating Research, a Colorado-based firm that works for Democrats, found Boebert leading Frisch, 47% to 45%, within the poll’s 4.4-percentage-point margin for error. Another 7% were undecided.

The results mark a 5-point shift in

Frisch’s direction since a July survey conducted by the same polling firm that found Boebert ahead, 49% to 42%, with 9% undecided.

Pollsters said the biggest movement since the July poll has been among the Republican-leaning district’s unaffiliated voters, who supported Frisch by an 8-point margin two months ago but prefer the Democrat by a 25-point margin in the most recent survey. Unaffiliated voters, who make up 44% of the district’s active registered voters and 37% of the poll’s sample, support Frisch, 57% to 32%, the new poll found.

Boebert’s favorability rating has dropped, too, the poll found, with 47% viewing the incumbent favorably and 49% viewing her unfavorably, up from 44% unfavorable responses in the earlier poll. Just 4% of voters say they’re unfamiliar with her.

Among unaffiliated voters, Boebert

is viewed favorably by 35% and unfavorably by 62%, with 60% of the unaffiliated saying they view her very unfavorably.

Frisch, a wealthy businessman who casts himself as a moderate

is viewed favorably by 38% of likely voters and unfavorably by 28%, with 35% saying they’re unfamiliar with Frisch, down sharply from the 65% of voters who said in July that they hadn’t heard of him.

Pollster Chris Keating told reporters that his client’s favorability rating points toward a winnable race.

“Do the voters who know you, like you?” Keating said during a remote press conference. “That’s the thing that I look for in a candidate that can win — is likability. He’s basically doubled his name ID, and voters like him, so down the stretch that’s only going to get better, too.”

Ballots start going out to most Colorado voters in less than two weeks. They’re due back to county clerks on Nov. 8.

The poll of 500 likely voters was conducted Sept. 28-Oct. 2 using a mix of live telephone interviews and text message. The pollster said the sample represents likely general election voters in the district based on party registration, gender, age, region, education and ethnicity.

Boebert won election two years ago by a comfortable, 6-point margin over Democratic nominee Diane Mitsch Bush after upsetting five-term Republican incumbent Scott Tipton in the primary.

She fended off a primary challenge in June from state Sen. Don Coram, a Montrose rancher, by a 2-1 margin. Frisch maintains that the Republicans and unaffiliated voters who voted against her in the primary make up the coalition of district residents who have grown weary of what he terms Boebert’s “angertainment” approach to government.
