Colorado Attorney General Phil Weiser, a Democrat, defeated Republican opponent Victor Marx in the gubernatorial race Tuesday as Democrats maintained their stronghold in the executive branch.

As of 9 p.m. Mountain time, Weiser, who received bipartisas endorsements, had received 1,191,726 votes or 62%. Marx had 635,632 votes, amounting to 33%, with 57 of 64 counties reporting.

Democrats also won the races for attorney general, secretary of state and state treasurer.

In the gubernatorial race, Weiser raised almost $9 million, nearly $5 million more than Marx. The two were at the center of campaign donation controversies when on October 6, the state issued a notice for an opportunity to cure illegal campaign donations.

Marx, the Republican challenger, also faced significant criticism over campaign donations and currently faces a near $60,000 fine for illegal contributions. Marx’s largest campaign contributor was himself. He donated almost $29,000 to his campaign.

Weiser served in both the Clinton and Obama administrations and as the dean of the University of Colorado Boulder’s law school. He’s built a long-term career in public service.

He has pledged to address Colorado’s affordability crisis by boosting the amount of homes Coloradans can buy through increasing payment assistance programs to first-time home buyers. Specifically, he has sought to address the barriers for homebuyers whose occupations fall within the category of first responders, teachers, and nurses.

Weiser was recently endorsed by 16 Colorado Republicans, such as former Attorney General Cynthia Coffman and former Senate Republican Leader Norma Anderson, alongside Planned Parenthood Votes Colorado, End Citizens United, Colorado Muslim Vote and more.

Marx was an untraditional candidate looking to shake up the stronghold Democrats have held in the governor’s office since 2007. He won the Republican gubernatorial primary by less than a 1% one margin against current state Senator Barbara Kirkmeier.

He said on his website that his policies were “common sense solutions that put Coloradans first,” and he pledged to hold the government accountable and make the state leaderships’ actions more transparent with its constituents. He also said he wanted to expand the workforce pipelines through supporting apprenticeship programs and alternatives to traditional four-year colleges.

Marx was endorsed by various Colorado sheriffs, pastors and military veterans.

Attorney general

Secretary of State Jena Griswold, the Democratic candidate for attorney general, defeated Republican District Attorney Michael Allen of El Paso County.

Griswold received 1,129,399 votes or 59% of the ballots. Allen received 778,508 votes, amounting to 41%.

The Democratic candidate raised a little over $2.6 million for her race, outpacing Allen by almost $2 million. Most of her contributions came from the Colorado Democratic party in the amount of $135,853.50.

Allen raised roughly $460,000 for his race. Allen’s top contributor is himself, who has spent $11,884.35 on the race.

Griswold was born in Ohio and grew up in a working-class home in Estes Park, Colo. She has a bachelor’s degree and a juris doctor, and started her career working in anti-corruption law. She then served on Barack Obama’s 2012 presidential campaign and worked for Democratic Colorado Governor John Hickenlooper in Washington, D.C. She later operated a small-business law practice in Louisville, Colorado.

She was endorsed by groups such as the Progressive Change Campaign Committee, Colorado Education Association and Progressive Democrats of America, as well as a long list of former congressional members, cabinet members and statewide elected officials.

Griswold’s main messaging point was a pledge to fight the Trump administration, writing on her website that she has “urged the U.S. Supreme Court to bar Trump from the presidency, and told Trump’s Department of Justice to take a hike when it requested Coloradans’ sensitive voter information.”

Allen currently serves as the 4th Judicial District’s district attorney and has been a prosecutor for more than two decades. After graduating from high school in Arvada, Colorado, he enlisted in the Navy and served until 1998.

He received substantial support from influential state actors, such as the Denver Post and Denver Gazette’s editorial boards, the Honorable Bill Owens, Colorado’s former governor from 1999 to 2007, and multiple police associations and county sheriffs. The Republican Attorney General’s Association and the National Rifle Association’s Political Victory Fund also endorsed him.

Allen promised to advocate for victims of crimes. He wrote on his website that he “worked to hold repeat domestic violence offenders accountable, and created Colorado’s first motor vehicle theft team that reduced motor vehicle theft by 50% in 2025.”

Secretary of State

James Wiley, a self-proscribed “Kennedy Libertarian” and Republican candidate for Colorado secretary of state, ran against Democratic candidate, Amanda Gonzales, for secretary of state.

Gonzales won the race Tuesday with 1,159,858 votes, totaling 61%.

Wiley received 704,608 votes, totaling 37%.

Gonzales won by roughly 30% of the vote in the June primary against her Democratic challenger, Jessie Danielson. She received 530,312 votes.

Wiley’s campaign expenditures outpaced his incoming donations by almost $10,000. The peak of his contributions came in the second quarter, around the time of the primary. A majority of his contributions come from individual donors contributing the maximum-allowed amount of $1,450.

Gonzales raised a little over $402,000 for her race and is endorsed by Colorado Education Association, LGBTQ+ Victory Fund, and Planned Parenthood Action. And a $15,000 donation came from Colorado American Federation of Labor & Congress of Industries.

Wiley, a Colorado native, called himself the “Red Flame of Liberty” in his biography for the Weld County GOP. He grew up in Colorado Springs and graduated with a master of business administration from Colorado State University, Pueblo.

He has served in a variety of liberty-focused organizations. He was director of Project Thaler, director of Save Our Suffrage, former executive director of the Libertarian Party of Colorado and secretary of the Chainsaw Caucus, a multiparty centrist political action committee.

Treasurer

The Democratic candidate for state treasurer, Jeff Bridges of Arapahoe County, defeated Republican Kevin Grantham of Fremont County in the general election.

Bridges received 1,129,362 votes, totaling 59%, and Grantham received 732,593 votes, totaling 38%.

Bridges currently represents District 26 in the state Senate and chairs the Legislature's joint budget committee. Grantham is a county commissioner who previously served in the state Senate for District 2, which covers Fremont and El Paso County.
