This page contains information on the regular 2024 election. For information on the June 2024 special election, see this article.


All U.S. House districts, including the 4th Congressional District of Colorado, held elections in 2024. The general election was November 5, 2024. The primary was June 25, 2024. The filing deadline was March 19, 2024. The outcome of this race affected the partisan balance of the U.S. House of Representatives in the 119th Congress. All 435 House districts were up for election.

At the time of the election, Republicans held a 220-212 majority with three vacancies.[1] As a result of the election, Republicans retained control of the U.S. House, winning 220 seats to Democrats' 215.[2] To read more about the 2024 U.S. House elections, click here.

In the 2022 election in this district, the Republican candidate won 60.9%-36.6%. Daily Kos calculated what the results of the 2020 presidential election in this district would have been following redistricting. Donald Trump (R) would have defeated Joe Biden (D) 58.0%-39.5%.[3]

Ballotpedia identified the June 25 Republican primary as a battleground primary. For more on the Republican primary, click here. For more on the Democratic primary, click here.


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.[5]

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."[6]

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.[7] 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.[8]

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.[9] 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.[10]

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.[11]

Richard Holtorf was a member of the Colorado House of Representatives. Holtorf said his experience as a military veteran qualified him for Congress.[12] 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.[13]

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.[14]

Peter Yu said his professional experience as a business executive and his desire to unite constituents qualified him for the congressional office.[15][16] 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.[17]

Boebert said she was a proven conservative fighter. Boebert's campaign website said, "Lauren took the fight directly to the Swamp after being elected to the U.S. House, establishing herself as an outspoken patriot willing to fight for Colorado and our conservative principles. She has received high marks from conservative organizations like Susan B. Anthony Pro-Life America, Conservative Review, Club For Growth, Turning Point Action and many others for her impeccable record of standing and voting for America First policies."


Boebert said one of her priorities was holding President Joe Biden (D) accountable for policies she believed were grounds for impeachment. Boebert's campaign website said she "was the first Republican in 24 years to initiate impeachment proceedings against Joe Biden for his dereliction of duty on securing our Southern border. As a member of the House Oversight Committee, Lauren has taken the Biden Crime Family to task for their rampant corruption and held this administration accountable for their failure to support our veterans and get them the care they have earned."


Boebert said she was one of few members of Congress to successfully get legislation signed into law in 2023. Boebert said, "My Pueblo Jobs Act was signed into law as part of the National Defense Authorization Act (NDAA). This bill will create at least 1,000 new jobs in Pueblo and help bring new businesses to Southern Colorado."

Key Messages

The border crisis is key to keeping our citizens safe. Without borders we have no country. The flow of illegal immigrants into our communities has not only created a financial crisis for these residents but has increased crime. The open borders has also opened a super-highway for drug trafficking from drug cartels from our southern neighbors.


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.

My parent's and my six brothers and sisters came to Colorado without a penny to their name and didn't speak a word of English.

I am a representative of the people and understand that this is not a career. This is a temporary opportunity to serve the people of my district, state, and country. My priority is the constituents, not Washington. I do not accept endorsements and will be sure to focus on real solutions, not campaign promises.


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.

Trisha Calvarese has always been fierce advocate for abortion rights. Trisha's fundamental belief that a woman's healthcare decisions should be between her and her doctor extends beyond abortion to her passionate support for Medicare, Medicaid and social security. These federal programs were critical to Trisha's mother and father when she moved home to provide end of life care to both of them before they died 13 days apart. Trisha also has a deep and profound passion for the American workforce. Her adult life has been primarily committed to expanding opportunities for American workers and keeping our nation competitive on the global stage.
Taxation reduction, Pro-2A, Economics, Anti-War, Radical Capitalist
One of my favorite figures I look up to is Joan of Arc. She fought to free her people from foreign invasion and taxation. She never gave up and endured so much to achieve her goals while living a life of purity.
“Human Action” by Ludwig Von Mises is the best book to read to fully understand my political position. “Capitalism: The Unknown Ideal” by Ayn Rand is an easier to read close second.
In contrast to Trisha's opponent, Lauren Boebert, Trisha feels it is critical for elected officials to be honest with their constituents, have compassion for their fellow Americans, and treat all Coloradans with respect and dignity.
I would uphold principles focused on individual liberty, minimal government intervention, free market economics, non-interventionist foreign policy, and the protection of civil liberties. These values prioritize personal freedom and responsibility, advocating for a society where individuals have the right to live their lives as they see fit, as long as they do not harm others.
I believe my steadfast commitment to libertarian ideals, such as individual liberty, minimal government intervention, and fiscal responsibility, equip me well for office. My honesty in communication and policy-making ensures transparency and trust. My dedication to these principles guides my decision-making, aiming to reduce government overreach and promote freedom. These qualities, combined with a strong ethical foundation and a proactive approach to problem-solving, position me as a candidate who can effectively advocate for change while upholding the core values of the libertarian philosophy.
Libertarians believe elected officials should prioritize protecting individual liberties, upholding the rule of law, ensuring a minimalistic and efficient government that intervenes as little as possible in the lives of its citizens, defending the country against aggression while advocating for a non-interventionist foreign policy, and fostering a free-market economy. Their core responsibility is to limit government's role to what is necessary for the protection of the rights and freedoms of individuals.
A world set free in my lifetime.
The Columbine School shooting was the first real historical event that I can remember. I was in 5th grade.
My first on the books job was working at the Sterling Country Club at the age of 14. I had it for one season.
I have read 1000s of books and it’s hard to pick just one. Probably one of my top favorites is “The Sorrows of Satan” by Marie Corelli is in my top two.
I would be Howard Roark in “The Fountianhead” by Ayn Rand.
The last song stuck in my head is “I’ll Come off the Mountain” by Sierra Ferrell off her new album “Trail of Flowers”
One of the most challenging moments in Trisha's life was when her dad got sick. Trisha's mother soon fell ill as well and she had to move home to provide end of life care to both of them. Before he died, Trisha's father, a lifelong Republican, encouraged her to run for office to put a stop to the toxic politics consuming our nation. She considers his support to be her first endorsement. Trisha's mother and father passed away within 13 days of each other leaving her with a heavy heart and a burning passion to join the fight to protect healthcare access for all Americans, especially our seniors.
Facing life as a teen mom in a women's shelter, surviving domestic violence, overcoming addiction, enduring the challenges of being a lower-middle-class wife, and navigating the heartbreak of my husband's serious illness, which will leave me a young widow, have been profound struggles. These experiences have not only shaped my personal journey but have also fueled my commitment to advocating for policies that support vulnerable populations and champion individual empowerment.
From a libertarian perspective, the U.S. House of Representatives’ unique qualities include its closer representation of the public due to its members’ frequent reelection every two years, which theoretically makes it more responsive to the will of the people. Its power of the purse, or ability to initiate revenue-raising measures, aligns with the libertarian emphasis on fiscal responsibility and limited government spending. Additionally, the House’s role in initiating impeachment proceedings reflects a mechanism for holding government officials accountable, resonating with the libertarian value of government accountability.
No, I do not believe it’s beneficial for representatives to have previous experience in government or politics. It’s time we stop buying our way into government and hand the power back to common people like me. It was designed for regular citizens representing each other not bought and paid for cronies.
Libertarians view the erosion of individual liberties, excessive government intervention and spending, and a lack of financial transparency as major challenges for the United States. They are concerned with the increasing size of government, the erosion of privacy rights, and ongoing military interventions abroad. Fiscal irresponsibility, particularly the national debt and unfunded liabilities, pose significant economic threats. Libertarians emphasize the need for a return to principles of limited government, personal freedom, and a non-interventionist foreign policy to address these challenges effectively.
I am for term limits. Absolute power corrupts absolutely.
I am a die-hard Ron Paul fan, Paul was known for his advocacy of limited government, non-interventionist foreign policy, civil liberties, and a free-market economy, aligning closely with libertarian values. His consistent focus on these issues has made him a prominent figure associated with libertarianism in American politics.
Yes. My own story. I am a homeschooling mom of four and I have been advocating for medical freedom for well over a decade. I got into politics to have my voice heard, and I relaxed there was no representation for someone like me. My husband is terminally ill and no one is coming to save me or my children’s future. So I am doing what I can to ensure a few world for my children and future generations.
We have (fill in the blank) at home.
I believe in advancing liberty and I will work with others to push the needle as hard as I can for that ideal.
As a libertarian elected to the House, leveraging the power to originate revenue-raising bills would be central to advocating for a smaller, more efficient government. This role would involve crafting and supporting legislation aimed at reducing taxes and government spending, thus promoting fiscal responsibility. It would also encompass scrutinizing and opposing measures that expand government's financial reach, ensuring that any new revenue requirements align strictly with constitutional liberties and the principles of minimal state intervention in the lives of individuals and the economy.
Libertarians generally believe the U.S. House should use its investigative powers to ensure government transparency and accountability. They advocate for investigations into government waste, violations of civil liberties, and misuse of power. These efforts are seen as crucial for minimizing government overreach and protecting individual freedoms.

I might align with the House Committee on Oversight and Reform, which focuses on government operations and the federal workforce, ensuring efficiency, transparency, and accountability. Additionally, the House Committee on the Judiciary, which deals with the administration of justice within the federal courts, administrative bodies, and law enforcement agencies, could also match my interest in protecting individual liberties and ensuring accountability. Also to represent my district t he House Committee on Agriculture. This committee is responsible for overseeing federal agriculture policy, ensuring agricultural industry regulations are fair, and addressing issues related to farming, food safety, and rural development.
Libertarians strongly advocate for financial transparency and government accountability, viewing them as crucial for a free society. They believe in the public's right to know how their taxes are spent and demand minimal government secrecy, arguing that transparency ensures that government actions remain in check and serve the public interest. Accountability mechanisms are essential to prevent corruption, waste, and abuse of power, ensuring that elected officials and government agencies act in accordance with the principles of liberty and justice.

General election race ratings

See also: Race rating definitions and methods

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.[18]
  • 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.[19][20][21]

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.
