U.S. Rep. Lauren Boebert (R) won the Republican primary for Colorado's 4th Congressional District. Boebert received 43.6% of the vote. Deborah Flora (R) finished in second with 14.8%, followed by Jerry Sonnenberg (R) with 12.0%, Michael Lynch (R) with 11.6%, Richard Holtorf (R) with 10.3%, and Peter Yu with 7.7%. Incumbent U.S. Rep Ken Buck (R) resigned on March 22, leaving the district open.[1]
Colorado Public News Public Affairs Reporter Caitlyn Kim said, "The announcement that GOP Rep. Ken Buck would not seek another term in office has set off a heated primary to fill a rare vacancy in the reddest district in Colorado. In late December 2023, the race gained even more prominence when Republican Rep. Lauren Boebert, who represents the 3rd Congressional District, said she would abandon plans to run for reelection there and instead seek the seat in the 4th."[2]
A Republican vacancy committee selected Greg Lopez (R) over Sonnenberg as the party's nominee in the June 25 special election to complete the remainder of Buck’s term.[3] Lopez said he would not run for re-election in November if he won the June 25 special election, which occurred on the same day as Colorado's primaries. Since Lopez won the special election and did not file for the June 25 Republican primary, the solid Republican district was open in November.
In a January 2024 debate, the candidates differed on abortion policies. Holtorf, Lynch, and Yu agreed that state legislatures should set abortion policy. Boebert, Flora, and Sonnenberg said they would support national restrictions on abortion. Lynch and Flora also criticized Boebert for running in a different congressional district, though Boebert said she moved to the district for personal reasons.[4]
As of June 5, 2024, Boebert raised $3.7 million total in campaign finance, followed by Flora ($426,258), and Sonnenberg ($356,179).
Boebert represented Colorado's 3rd Congressional District. Boebert said she supported America First policies, a term often associated with the platform of former President Donald Trump (R) and candidates who said they supported Trump’s agenda.[5] On her campaign website, Boebert said she supported the impeachment inquiry into President Joe Biden (D). Boebert said she supported bills focusing on increasing energy production and opposed the Bureau of Land Management. Former President Trump and U.S. Speaker of the House Mike Johnson (R) endorsed Boebert.[6]
Deborah Flora said her experience as a small business owner made her qualified compared to career politicians. Flora said she supported reducing government spending, requiring Congress to balance the federal budget, limiting illegal immigration at the U.S.-Mexico border, and policies that reduce energy costs.[7]
Richard Holtorf was a member of the Colorado House of Representatives. Holtorf said his experience as a military veteran qualified him for Congress.[8] Holtorf said he would focus on reducing inflation that he said President Joe Biden’s (D) policies created.
Michael Lynch was a member of the Colorado House of Representatives and was the minority leader from 2022 to 2024. On his campaign website, Lynch said he supported measures that would reduce the role of government in people’s lives, lower taxes, limit illegal immigration and fentanyl trafficking at the U.S.-Mexico border, and protect gun ownership.[9]
Jerry Sonnenberg was a member of the Colorado Senate from 2015 to 2023, and served in the Colorado state House from 2007 to 2015. Sonnenberg said he supported reducing inflation that he said Biden's policies created, limiting illegal immigration at the U.S.-Mexico border, increasing energy production from oil and natural gas, and reducing environmental regulations for ranchers and farmers.[10]
Peter Yu said his professional experience as a business executive and his desire to unite constituents qualified him for the congressional office.[11][12] Yu said he supported reducing illegal immigration at the U.S.-Mexico border, reducing government spending, increasing domestic energy production, and lowering the national debt.[13]

Deborah Flora (R)
Economy: Balancing the budget, stopping government's out of control spending and lowering inflation.
Educational freedom and protecting parental rights.
Michael Lynch (R)
Mike has been signing both sides of a paycheck for the last 23 years. He understands business and the importance of protecting it from government overregulation. He believes free market capitalism is what has made America the best country in civilization.
Mike is a man of faith that believes in conservative family values. He puts family first and believes there is no greater job than raising the next generation of patriots that will continued the traditions of American exceptionalism.
Jerry Sonnenberg (R)
Inflation has cost the average family an extra $15,000 to maintain the same standard of living that they had just a couple of years ago. I don't know of many people that have had an increase in their wages to cover the higher cost of everyday necessities. Our national debt as well as our government printing and distributing more money has devalued every citizens bank account and until we cap our debt and get our spending under control, government will drive its citizens into the poor house.
Polarization and divisiveness in government has led the citizens to not trust their leaders. Integrity and character should be a priority among our leaders and even though our elected officials may disagree on policy, they should work to solve the problems of this country and quit playing political games. The people of America deserve a representative that has a proven track record of solving problems with integrity and character.
Peter Yu (R)
I have a corporate background where my responsibilities were to handle large projects, budgets, operations, and teams. As having experience in resolving issues and working with multiple variables, I feel that this is what is needed in Washington. Being in a results oriented environment will help make progress in creating legislation for the people of our country.
Actions matter. I have spent my entire campaign working to meet the people of our district and state. I spend eight plus hours canvassing and knocking on doors each day. It is important to meet as many constituents as possible to hear their concerns and to show true representation.

Polls

Polls are conducted with a variety of methodologies and have margins of error or credibility intervals.[14] The Pew Research Center wrote, "A margin of error of plus or minus 3 percentage points at the 95% confidence level means that if we fielded the same survey 100 times, we would expect the result to be within 3 percentage points of the true population value 95 of those times."[15] For tips on reading polls from FiveThirtyEight, click here.

Ballotpedia provides race ratings from four outlets: The Cook Political Report, Inside Elections, Sabato's Crystal Ball, and DDHQ/The Hill. Each race rating indicates if one party is perceived to have an advantage in the race and, if so, the degree of advantage:
- Safe and Solid ratings indicate that one party has a clear edge and the race is not competitive.
- Likely ratings indicate that one party has a clear edge, but an upset is possible.
- Lean ratings indicate that one party has a small edge, but the race is competitive.[16]
- Toss-up ratings indicate that neither party has an advantage.
Race ratings are informed by a number of factors, including polling, candidate quality, and election result history in the race's district or state.[17][18][19]

Post-filing deadline analysis
The following analysis covers all U.S. House districts up for election in Colorado in 2024. Information below was calculated on May 2, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.
Thirty-two candidates ran for Colorado’s eight U.S. House districts, including 12 Democrats and 20 Republicans. That’s 4.00 candidates per district, more than in the previous three election cycles. There were 3.75 candidates per district in 2022, 2.28 candidates per district in 2020 and 3.43 in 2018.
The number of candidates who ran for the U.S. House in Colorado in 2024 is also higher than any other year this decade.
The 3rd and 5th Congressional Districts were open, meaning no incumbents ran in those districts.
Rep. Lauren Boebert (R-3rd) ran for the 4th Congressional District, which Ken Buck held before he resigned from Congress on March 22, 2024. Rep. Doug Lamborn (R-5th) did not run for re-election because he retired from public office.
Nine candidates—three Democrats and six Republicans—ran for the 4th Congressional District, the most candidates who ran for a seat in Colorado in 2024.
Seven primaries—three Democratic and four Republican—were contested in 2024. That’s less than the eight contested primaries in 2022 but more than the two contested primaries in 2020.
Two incumbents—Reps. Diana DeGette (D-1st) and Boebert—were in contested primaries in 2024. That's less than the four incumbents in contested primaries in 2022 but more than the one incumbent in a contested primary in 2020.
Candidates filed to run in the Republican and Democratic primaries in all eight districts, meaning no seats were guaranteed to either party.Partisan Voter Index
Heading into the 2024 elections, based on results from the 2020 and 2016 presidential elections, the Cook Partisan Voter Index for this district was R+13. This meant that in those two presidential elections, this district's results were 13 percentage points more Republican than the national average. This made Colorado's 4th the 111th most Republican district nationally.[23]
2020 presidential election results
