U.S. Rep. Lauren Boebert is on track to return to Congress from her newly adopted district Tuesday night by winning the crowded GOP primary in Colorado’s 4th Congressional District.

At the same time, Republican Greg Lopez won election to serve out the remainder of former five-term U.S. Rep. Ken Buck’s term, following Buck’s resignation from the U.S. House earlier this year. Lopez, a former Parker mayor and two-time gubernatorial candidate, led Democratic nominee Trisha Calvarese by double digits.

The Associated Press declared Boebert had won the primary at 7:22 p.m., not long after polls closed. Lopez was declared the winner 10 minutes later.

“Our campaign stayed focused on the issues impacting Coloradans and my proven track record as a conservative fighter who gets results for our state,” Boebert said in a statement. “That won’t change as we move to November and focus on growing our House majority that will stand strong with President Trump when he retakes the White House.”

Boebert led the vote tally at 11 p.m. with 51,877 votes, or 43% of the total, with former state Sen. Jerry Sonnenberg and parents rights activist Deborah Flora vying for second place, with 17,300 and 16,389 votes, respectively, or around 14% apiece. State Reps. Richard Holtorf and Mike Lynch were nearly tied for fourth place, with Holtorf at 12,928 votes and Lynch with 12,746, or roughly 11% each. Business consultant Peter Yu brought up the rear with 8,446 votes, or 7%.

Calvarese also took an early lead in her party’s primary for the November election, with Ike McCorkle and John Padora trailing.

At 11 p.m., Calvarese had 21,842 votes, or 45%, while McCorkle had 19,850 votes, or about 41%. Padora had 6,582 votes, or about 14%.

Calvarese said she was ready to take on Boebert in the general election.

“CD4 is where I grew up; it is where I returned to care for and lay my parents to rest and where I will build my family,” Calvarese said in a written statement.

“Our win tonight shows that our district wants a representative that is a champion for working families, not the dysfunction Lauren Boebert has brought to Congress. She moved here because she thought she could win in this district, but that’s before I got into this race,” Calvarese added. “From Yuma to Highlands Ranch, we know folks want more than chaos. They want someone who represents their values.”

In the vacancy election, Lopez defeated Calvarese with 95,742 votes, or 58%, in preliminary results posted at 11 p.m. Calvarese had 56,627 votes, or 35%, with Libertarian Hannah Goodman at 8,616 votes, or about 5%. Approval Voting Party nominee Frank Attwood had received 3,127 votes, or about 2%.

Lopez savored his victory and said he planned to be sworn in as soon as soon as possible.

“Neither of my parents had the opportunity to graduate from high school, and yet, this evening I was elected to serve in the United States House of Representatives,” Lopez said in a written statement. “I truly feel I am a living testament that regardless of who you are or where you come from, we can all be a part of the American Dream. That said, the real work starts now.”

Adding that he intends to take office right after Colorado Secretary of State Jena Griswold notified the House speaker, Lopez added that h was “ready to serve all the residents of the district with honor and integrity, regardless of whether or not they voted for me.”

Boebert, the state’s most prominent Republican, announced late last year that she was moving from the Western Slope-based 3rd Congressional District into Buck’s more favorably Republican district on the eastern side of the state after nearly losing her seat in 2022.

Instead of clearing the field, however, Boebert’s move was denounced as “carpetbagging” by fellow Republicans, including nearly a dozen who vied along with her to replace Buck in Colorado’s most solid GOP seat. Eventually, six Republicans, including Boebert, made the ballot, but none matched her fundraising lead and high-profile advantage.

In early returns, Boebert jumped out far ahead of her her Republican rivals and never relinquished the lead.

Buck created only the second U.S. House vacancy in state history in March when he abruptly resigned, citing the GOP’s internal divisions and devotion to former President Donald Trump, who endorsed Boebert’s primary bid.

Anchored by Douglas County and portions of Larimer and Weld counties along the Front Range, the 4th CD covers Colorado Eastern Plains, including all or portions of 18 additional counties. Republicans outnumber Democrats by more than two-to-one in the district, although there are more unaffiliated voters than members of either major party.
