After a recount in a remarkably close race, Representative Lauren Boebert of Colorado, known for heckling President Biden during his State of the Union speech, arming herself on Capitol Hill and ignoring Covid mask rules, won her bid for a second term. Colorado’s secretary of state, Jena Griswold, announced the results on Monday.
Ms. Boebert, 35, staved off a fierce challenge from Adam Frisch, a Democratic businessman and former Aspen, Colo., city councilman, in the state’s Republican-leaning Third District.
Mr. Frisch, who faced a deficit of roughly 500 votes out of more than 327,000 cast, gained just two votes in the automatic recount. In the end, Ms. Boebert won with 50.06 percent of the vote, to Mr. Frisch’s 49.89 percent.
On Twitter on Sunday, before the recount was made official by the secretary of state, Ms. Boebert said: “Our conservative policies will help all Americans to overcome the challenges we face so each of us has the opportunity to live our very best life. Thank you for entrusting me to help lead the way. I’ll be working every day to prove I can get the job done right.”
Mr. Frisch had sought to cast Ms. Boebert as a flamethrower in an increasingly polarized Congress, saying she was focused more on placating the Republican Party’s far-right Trump wing than on reducing inflation and adding jobs.
He presented himself in a television ad as not a typical Democrat, saying that he would not vote for Representative Nancy Pelosi for House speaker and that he supported border security. He showed footage of himself hunting with a shotgun.
But a disadvantage in name recognition and the makeup of voters in the district proved too much for Mr. Frisch to overcome against Ms. Boebert, who has drawn national attention for her incendiary actions.
On Monday evening, he released a statement on his loss. “While we hoped for a different outcome,” Mr. Frisch said, “we defied incredible odds with the closeness of this race.” He added, “I am confident that the coalition of Democrats, Republicans and unaffiliated voters we built throughout this campaign to reject hate and extremism in Southern and Western Colorado will grow into the future.”
Along with Representative Marjorie Taylor Greene of Georgia, a fellow Republican also in her first term, Ms. Boebert brought a no-holds-barred brand of politics to the House, feeding off a social media echo chamber of loyalists who backed former President Donald J. Trump. That has put Ms. Boebert at odds with platforms like Twitter, which temporarily suspended her account after she spread the falsehood that the 2020 election was rigged.
Her rhetoric and her style of politics also made her a target of Democrats during the Republican primary, many of whom crossed party lines to support her Republican challenger, driven by fears of her extremism.
Ms. Boebert won her seat in Congress in 2020, when she unseated a five-term incumbent in the Republican primary before going on to win the general election. Until then, she had run a gun-themed restaurant in Colorado’s ranch country — the Shooters Grill — where she encouraged staff members to carry firearms and defied restrictions by staying open during the pandemic.
