Elizabeth Warren

Elizabeth Warren, U.S. Senator

“Diane Mitsch Bush is a fearless advocate who understands the importance of putting people first. She will stand up for working families, consumers, better wages and good paying jobs – not for Wall Street, billionaires, or CEOs who already have too much influence in Washington. I look forward to working with Diane in Congress, and am proud to support her.”

Raúl Grijalva

Raúl Grijalva, U.S. Congressman – Arizona’s 3rd District

“I’ve watched Diane build the grassroots support for her campaign that’s needed to deliver an election defeat to Scott Tipton in November. By electing hard-working people of integrity, such as Diane, we will begin to reverse the damage of the Trump administration. Diane has the courage to fight for the people of this country, not for the corporations who fund Scott Tipton. In this primary election, I ask you to choose a proven winner and a demonstrated leader. Diane Mitsch Bush has developed a strong and viable campaign operation; and she has a solid, progressive record as a local elected official. I look forward to working with her in the House of Representatives.”

John Hickenlooper, Governor of Colorado

“I’m proud to endorse Diane Mitsch Bush for Congress. I worked closely with Diane during her time in the Colorado Legislature…she is both hard-working and dedicated to her community. Diane’s experience and fact-based legislating would make her a strong voice for Colorado’s 3rd Congressional District.”

Ken Salazar

Ken Salazar, Former U.S. Senator and former U.S. Secretary of the Interior

“Diane has gained a reputation, through her strong record, as a champion for the causes that matter most to us in the 3rd Congressional District. Whether she is dealing with water, jobs and the economy, public lands, agriculture, or transportation, Diane brings people of all political stripes to the table for common sense legislation that benefits her constituents. Only a person with Diane’s broad appeal and legislative experience can win back this seat for the people of CD3. I proudly endorse her.”

Mark Udall

Mark Udall, Former U.S. Senator

“I am proud to endorse Diane Mitsch Bush for Colorado’s 3rd Congressional District. As a Senator and Congressman from our great state, I know how difficult it is to balance the interests of a diverse set of constituents. Diane has proven to voters that she is their progressive champion and has an incredible ability to unite competing factions for positive change. It’ll take unwavering commitment, integrity, and an understanding of the way forward to undo the damage caused by the Trump Administration. Diane is honest, trustworthy, and dedicated to public service – a breath of fresh air for the people of the 3rd Congressional District. I could not imagine a more qualified candidate, and Diane is the one we need to bring the 3rd Congressional District back under Democratic leadership.”

Bill Ritter

Bill Ritter, Former Governor of Colorado

“I met Diane back in 2006 on the campaign trail. She was running for her first term as a Routt County Commissioner and I was running for Governor. I saw her build relationships across the partisan divide, connecting with voters of all political affiliations. Unlike so many today, Diane has a unique ability to relate to people of all walks of life, listen to voters and work tirelessly to solve constituents’ problems.

Diane has always been a champion for the people and for our environment. As a County Commissioner, Diane successfully worked with her colleagues and the community to lower Routt County’s carbon footprint with innovative solutions that also saved taxpayer dollars. She’s fought for our clean water, air, and wildlife, and was deservedly awarded Conservation Colorado’s 2017 Legislator of the Year. Diane is the pioneering, forward-thinking, environmental steward we need to protect our home, Colorado’s way of living, and our economic foundation.

As we look forward to November, we need a candidate in Colorado’s 3rd Congressional District with a progressive vision and the experience to legislate effectively. But equally important, we need a candidate who can win. I’ve already seen Diane flip a Republican held seat, winning overwhelmingly in an area where Democrats were outnumbered by both Unaffiliated and Republican voters. I know she’ll do it again in November.

Diane is the candidate of the people and the only one who can turn Colorado’s 3rd Congressional District blue again.”

EMILY’s List

“Diane Mitsch Bush is deeply committed to expanding economic opportunity for rural Coloradans. As a former public servant and educator, Diane is running for Congress to improve access to affordable health care, increase investments in public education and protect Colorado’s beautiful public lands. Her track record in the Colorado House and as a public county commissioner proves that she will be the strong voice working families need fighting for them in Washington.

Diane is running to flip a seat in a critical swing state that has voted for Democrats in recent presidential elections and has the potential to become even more blue. She is running to face incumbent Republican Congressman Scott Tipton, who has voted for President Trump’s disastrous agenda nearly 100 percent of the time, including to take away affordable health care. Coloradans deserve a new voice representing their best interests in Washington, and Diane has proven that she will be that representative. Let’s show her our full support so that hardworking families in the 3rd District will finally have a representative in Congress who speaks for them.”

Bennett Boeschenstein, Mayor Pro Tem of Grand Junction

“The City of Grand Junction, and Colorado’s 3rd Congressional District as a whole, deserves a Congressional Representative worthy of that seat and dedicated to the future of each and every voter. I could not think of a better replacement for Scott Tipton than Diane Mitsch Bush, and I’m excited to endorse her for US Congress. Diane understands that communities like Grand Junction need more than just highways – we need true multimodal transportation. As the Chair of the Transportation and Energy Committee in the CO House, Diane pushed for investment in rail, mass transit, and bike paths – to name a few. She continually advocates for a substantial infrastructure investment that would fulfill our vision of a truly connected Grand Junction and Colorado. The citizens of Mesa and Grand Junction also need a Representative in the US House that understands that environmental protection is intertwined with economic prosperity. With 70% of Mesa County considered public lands, and with the City of Grand Junction invested in conservation efforts like our Biogas Project, our Las Colonias Park Project, and our Watershed Protection Ordinance, our next leap is dependent upon a Representative that values our surrounding environment. Diane was Conservation Colorado’s Legislator of the Year and has spent most of her life, both privately and as a public servant, fighting for environmental advocacy. We need a compassionate, honest, intelligent, and dedicated Representative whose faithfulness resides with voters. We need Diane and we must all work to ensure that she is elected in November.”

Dylan Roberts, Colorado State Representative

“I enthusiastically endorse Diane Mitsch Bush for U.S. Congress for two reasons: because she will beat Scott Tipton and when she does, she will be an excellent Congresswoman. I have had the privilege of knowing Diane ever since she was a Routt County Commissioner when I was growing up in Steamboat. As I was getting started in local politics, Routt County was not a Democratic stronghold but Diane consistently won tough elections through hard work and her ability to connect directly with voters across the political spectrum. As an interested constituent of hers, I watched Diane in her role as State Representative consistently be the most prepared, thoughtful, and passionate advocate for her district. She always prioritized the needs of her constituents above all else. Her record of winning elections and dedication to making people’s lives better is exactly the type of person we need in Congress. I hope you will vote for Diane and get in your ballot by June 26th!”

Rachel Richards, Pitkin County Commissioner, Former Mayor of Aspen

“I admire Diane for being the first to step out and challenge our federal congressional incumbent, in order to start putting real time into the grassroots work of building coalitions across this wide district to carry her into office this November. I believe it shows how hard she, and all of us, will need to work this fall to elect a representative who works for the good of the people instead of special interests. The time is right for someone who runs on really knowing the issues, their impacts on our citizens’ everyday lives, and who has solid legislative experience and has advanced real solutions to difficult issues. Please join me in voting for Diane Mitsch Bush on your primary ballot this month.”

Durango Herald

“The Democrat most prepared to be an effective voice in Washington is former two-term state representative Diane Mitsch Bush of Steamboat Springs, who has been a member of Club 20’s executive board and who has taught full time at Colorado Mountain College.

Bush would advocate for all of the Democratic Party’s positions, including protecting the Affordable Care Act, extending Medicare with additional funding for rural costs and strengthening the Civil Rights Act. Adequate health care, for Bush, is a right. In the state house, she co-sponsored successful legislation allowing Dreamers to pay in-state tuition to public colleges.

In her presentations, Bush comes across as eager to make a difference and fearless, more than ready to apply her abundant energy.

The Herald’s editorial board urges Democrats to vote for Diane Mitsch Bush for the 3rd Congressional District on the party’s primary ballot, which should reach voters this week by mail.”

Sal Pace, Pueblo County Commissioner

“I endorse Diane Mitsch Bush in the race for Colorado’s 3rd Congressional District. Diane recognizes the importance of Pueblo to the District, and to this election.

She will be our strong Champion in Washington. I know this because Diane has always stood up for working people. That is why the AFL-CIO endorsed her. Although Diane is not from Pueblo, she is one of us. She will work for us, every day, to bring the resources we need to support small businesses and retain manufacturing jobs that pay a living wage. Please help me elect Diane Mitsch Bush today.”

Cody Perry, Co-Founder of Rig To Flip

“Diane Mitsch Bush knows Colorado’s 3rd District. Whether it’s standing up for public lands or advocating for the benefit of our communities and rural western character, Diane has the heart and experience to represent our desires of a prosperous and healthy Colorado for all.”

Blue Wave Crowdsource

“A two-time County Commissioner and three-term Colorado State House Representative, Diane Bush has a long history of dedicated public service. With over 12 years of experience as a public servant and over 25 years as a social science policy researcher and environmental advocate, Diane is deeply passionate about protecting the natural environment, reforming public education, and ensuring that civil rights are upheld.

After graduating from the University of Minnesota with a degree in Social Policy and Sociology, Diane moved to Steamboat Springs with her husband to finish up her PhD studies and immediately immersed herself in public service. Diane partially attributes her experience living and working in rural communities across Colorado as the foundation upon which many of her policies rest.  An avid skier, rock climber, mountain biker and overall outdoor enthusiast, Diane’s commitment to serving the public comes from a deep-seated love of the natural environment and honest care for the people in her community.”


I am proud to announce that AFL-CIO has endorsed our campaign for Congress! The Colorado AFL-CIO represents approximately 180 affiliate unions, whose membership totals more than 130,000 working Coloradans. I am honored that they have chosen to stand behind me in this race.

I learned the importance of unions at a young age. After experiencing wage discrimination and sexual harassment in the workplace, my mother changed careers, began working for her local county government, and joined the largest trade union of public employees in the US, AFSCME (American Federation of State, County and Municipal Employees). AFSCME ensured that my mother was treated fairly at work, and they provided us income predictability so we no longer had to rely on payday loans.

In the Colorado State House, I worked with my colleagues to strengthen workers’ safety and workers’ rights. Now we must take that fight to the federal level. I will continue to work everyday for living-wage jobs, for workers’ safety, and to strengthen collective bargaining. I promise to always be a champion for working people.

Progressive Democrats of America

“The Denver chapter of Progressive Democrats of America, PDA, is pleased to announce our endorsement for Diane Mitsch Bush, candidate for Colorado’s 3rd Congressional District. Diane is an advocate for protecting rural lands and has signed the pledge in support of the OFF Fossil Fuels for a Better Future Act. She is passionate in her beliefs for universal, single-payer healthcare and has been diligent in her work ensuring that healthcare is affordable for all Coloradans.  Diane also recognizes that a clean Dream Act is essential and knows that immigration reform is achievable.  Denver PDA is proud to endorse Diane and appreciates that she will continue listening to her constituents and continue fighting for them.”

Gunnison Political Revolution

“The Gunnison Political Revolution is proud to announce its endorsement of Diane Mitsch Bush. In Diane we have found an energetic, authentic leader who can defeat Scott Tipton in 2018. When she does, she will champion progressive causes for a broad spectrum of supporters and issues from campaign finance reform to health care for all.  We hope you will join the Gunnison Political Revolution in getting her elected. She is one of us.”

Blue Rising PAC

“Blue Rising is excited to endorse Diane Mitsch Busch for CD-3. We know that Diane will be an invaluable voice for the people of the district. As a former 2-term county commissioner and 3-term Colorado State House Representative, Diane has already proven to be a champion of women’s rights and environmental protection, and she’s worked tirelessly to expand economic opportunity for everyone. She has the experience, skills, and dedication to make our communities stronger and safer.”

Former U.S. Assistant Secretary of Homeland Security for Intergovernmental Affairs and former Colorado Congresswoman, Betsy Markey

“It’s important to have smart and thoughtful women like Diane in Congress, who will lead with a strong sense of purpose and a good heart.”

Colorado House Majority Leader, KC Becker

“I proudly endorse State Representative Diane Mitsch Bush for the U.S. House of Representatives. It’s high time Southern Colorado and Colorado’s Western Slope have the representation in Washington that we deserve and Diane is the woman for the job! I’ve fought alongside Diane on a number of issues and each and every time I have worked with her, she fiercely advocates for her constituents and stands up to special interests for the unique communities that make up her district. Diane’s current State House District neighbors mine to the west, stretching from the Wyoming Border in Routt County down to Eagle County and the Roaring Fork valley—so she gets it: She has seen firsthand the challenges that rural Colorado is facing, and she will work tirelessly to find solutions to benefit her rural constituents just as she has done in the Colorado House. I’ve worked alongside Diane on issues such as: Protecting our environment, water, and wildlife, making quality health care accessible and affordable, leveling the economic playing field, and increasing the quality of life for all Coloradans by creating good paying jobs and expanding educational opportunities for all. For too long, Colorado’s 3rd Congressional District has NOT been getting the representation it deserves. Let’s change that. I’ve known Diane since I first came on board at the Colorado State Legislature in 2013. We served together on the House Agriculture, Livestock, and Natural Resources Committee, and I saw firsthand how knowledgeable she is on issues that are integral to our Colorado way of life and more importantly – how willing she is to listen to and share the concerns of her constituents.”

Representative Daneya Esgar from Pueblo

“Diane has been a champion for our water rights and worked with countless people throughout the state to help create our Colorado Water Plan. As Vice-Chair of the Agriculture Committee she fought for family ranchers and farmers, earning recognition from the Farm Bureau and Legislator of the Year from both The Rocky Mountain Farmer’s Union and The Colorado Livestock Association. Diane will always fight for her constituents and I’m excited to endorse her to unseat Scott Tipton.”

Representative Barbara McLachlan from Durango

“I’m thrilled to announce that I endorse Diane Mitsch Bush in her bid for Congress!From the first day we worked together at the State Legislature, I knew my time spent with Diane wouldn’t only build a partnership; we built a lasting friendship, rooted in our shared values. Diane advocates for the environment, making health care accessible and affordable, creating good paying jobs, and access to quality education for all. Because she serves as the chairwoman of a committee I’m on—the Transportation & Energy Committee—I’ve had a front row seat to witness Diane’s work ethic. What struck me after working alongside her this past session is that she always does her homework. She doesn’t just accept information as she hears it; Diane does extensive research into topics and how a bill would affect her district before making her decision on how to vote. A Steamboat Springs local for over 40 years, Diane understands the issues small towns face, including the high cost of living and how our problems differ from those facing the Front Range. Her passion for and knowledge of how to address the issues facing the Western Slope mean she is a valued, respected voice in our committee meetings. Working toward a better future for all has been Diane’s life mission: working as a public servant for the past 40 years. Before she was elected as the State Representative for Eagle County & Routt County, Diane served two terms as a Routt County Commissioner where she worked with ranchers, farmers, and cattlemen to address issues in the community. Diane knows what it means to live in rural Colorado. And frankly, she doesn’t take grief. Diane knows what her district needs, knows what it’ll take to make real change, and knows how to fight to make it happen. It’s obvious when you meet Diane that working toward a better, more equitable and sustainable Colorado for all is her passion. It’s past time to take back this seat from Scott Tipton. I am confident Diane is the candidate who will win this race. With proud enthusiasm, I support Diane Mitsch Bush as the Democratic Congressional Candidate in 2018.”

Representative Jessie Danielson from Wheat Ridge

“I’m thrilled to endorse State Representative Diane Mitsch Bush in her bid to unseat Scott Tipton in Colorado’s 3rd Congressional District. I’ve known Diane since 2014, when I started serving in the Colorado State Legislature. She currently represents a rural district in the Colorado House—House District 26, Eagle County & Routt County. I grew up on a family farm in Ault, Colorado, which means I get it: agriculture is the foundation of everything we are and are able to do here in Colorado. Diane serves as the Vice-Chair of a committee I also sit on, the House Agriculture, Livestock, and Natural Resources Committee. I saw firsthand how knowledgeable she is on issues that are integral to our way of life such as water rights, land usage, wildlife preservation and protecting the environment. I have also fought alongside Diane on other issues, such as: Defending pro-choice policies, ensuring quality education for our students, and working to open more doors to success for all Coloradans—especially working-class families. Diane has pledged to address the sky-high cost of health care and health premiums in rural Colorado, as evident by her bill HB17-1235 from this past session. Her dedication to working for Coloradans is apparent in the bills she has put forward during the past two sessions we’ve served together in the Colorado House of Representatives.”

Representative Adrienne Benavidez of Adams County

“Diane will stand up for the rights of all people. I have seen her do it in Colorado’s State House. She is a courageous and effective legislator who can be trusted to fight for her constituents.”

Former Town Trustee from San Luis, The Honorable Gabrielle V. Aragon

“I am excited to formally endorse Diane Mitsch Bush in her bid to unseat Scott Tipton in Colorado’s 3rd Congressional District. For those of you who do not know me, my name is Gabrielle Aragon. I am an 8th generation Coloradan from San Luis, the oldest town in Colorado located in Costilla County — “where Colorado began”. The values instilled in me, passed down by my forefathers, are the pillars of Colorado; they are that of land, water (sin agua no hay vida), people, agriculture, and faith. I grew up knowing that a person’s name and reputation are the most valuable aspects of one’s character. I am cautious of those I recommend to others and I would only endorse someone who will truly represent the values of San Luis, someone who will listen to our community and work for our people. Diane is that person. When I first met Diane years ago, she stood out to me because she had an effervescent energy about representing people. Diane is one of the most approachable, down-to-earth, passionate, and intelligent representatives I know. She takes the time to truly engage with people by listening, asking questions, hearing ideas and concerns, and gaining perspective. Diane is someone who is eager to roll up her sleeves to find solutions and help out everyday people. She took many of our values to the State Capital and reminded Denver that we are part of Colorado too! For these efforts, she was named Legislature of the Year for her work on the House Agriculture Committee and the Natural Resources Committee. Rural Colorado and rural America have become neglected in Washington politics. We are not truly represented or respected. When I became the youngest elected official in Colorado, I encountered dead ends in trying to improve the quality of life for my constituency – I know how difficult it can be. Diane always works for her people and she will build the bridges over which our community can cross. Diane will fight to provide quality jobs, a world-class education, affordable healthcare and incentives for farmers. She will protect our way of life and the environment here in San Luis. We are from the greatest and most fertile valley on earth, but just because we are from a valley doesn’t mean our voices should be trapped, forgotten or treated like second-class citizens. We in San Luis are Coloradans, but above all we are Americans and demand the best! That is why Diane Mitsch Bush is the best candidate in this race, on any side, to represent our values and to fight for what everyday people like you and me need. It’s long overdue. Whether you own 5 cattle or 50,000 cattle, use the water to ski in the winter or to irrigate in the spring for your peaches, potatoes, alfalfa or a small garden, be confident that Diane will always create the best opportunity for everyone.”

Former Colorado Director of Local Affairs and former Fort Collins Mayor, Susan Kirkpatrick

“I have seen Diane in action since the mid-1980’s when she served on the Fort Collins Committee on the Status of Women and I was the Mayor of Fort Collins. She is tenacious and brings people together for effective legislative solutions. Her knowledge of transportation funding and policies and her passion for real infrastructure investment will help move Washington in the right direction.”

Former Vice President of Colorado Mountain College Edwards, Peggy Curry

“When I first voted for Diane for the Colorado State House, I was certain she would succeed given her local government experience and her understanding of the particular challenges that Colorado faces. She has exceeded all expectations. She has an unbelievable work ethic and we need her now more than ever. She is our best choice for healing the divisiveness in D.C. and achieving desperately needed bi-partisan legislation on education reform, healthcare, and climate change.”
