DENVER — A panel of Colorado Republicans will select a candidate Thursday who will likely serve out the final months of U.S. Rep. Ken Buck ’s term — and could pose a challenge to Rep. Lauren Boebert’s bid for another term in Congress.

It’s an unusual and confusing twist in a closely watched primary race for a district the far-right Republican Boebert has not represented previously. Whoever the committee chooses is expected to prevail in the special election against the Democratic nominee, finish Buck’s term and reinforce Republicans’ slim majority in the U.S. House.

But the decision could have farther-reaching consequences. The committee is expected to pick one of the current Republican primary candidates competing for the same seat. Boebert opted to finish her current term in her old district, and the committee will likely select one of her rivals.

Whoever is picked would be running in two separate races for the same seat until the June election, giving them greater notoriety, media coverage and expanded fundraising opportunities — a boon for most of the candidates who fall far short of Boebert’s national name brand and campaign chest.

“Ken Buck really threw a wrench into the whole thing,” said Seth Masket, director at the Center on American Politics in Denver, who noted that it’s unclear what Buck’s intentions are. “It was already a fairly topsy-turvy race, but I think this does make it a little bit harder for her.”

Boebert said in a recent statement that the move was interference: “The establishment concocted a swampy backroom deal to try to rig an election.”

The congresswoman has built a far-right name with a ferocious political style, in step with the accusation of election rigging, and remains a known, if divisive, quantity among conservatives nationwide.

While Boebert has made headlines with scandals, including a tape of her groping and vaping with a date in a Denver theater, she’s also garnered endorsements from former President Donald Trump and current Speaker of the House Mike Johnson.

She defended the move by saying her voice is still needed in Congress, and that her exodus from the old district makes it easier for Republicans to retain the seat, and therefore their majority in the U.S. House.

The option to district hop was opened to Boebert after Buck announced he wouldn’t run for reelection last year, citing his party’s handling of Trump.

Then, earlier this month, Buck abruptly resigned, pointing to the “bickering and nonsense” he said now pervades the U.S. Capitol. Buck left Congress on March 22.
