John Hickenlooper

In 2003, Hickenlooper ran for mayor of Denver. Campaigning on his business experience, he developed a series of creative television ads that separated him from the rest of the crowded field, including one in which he addressed unhappiness over a recent increase in parking rates by walking the streets to "feed" meters. He won the election and in July 2003 he took office as the 43rd mayor of Denver. TIME Magazine named him one of America's five best big-city mayors in 2005.

On taking office, Hickenlooper inherited a "$70 million budget deficit, the worst in city history", which he was able to eliminate in his first term "without major service cuts or layoffs", according to Time. He won bipartisan support for a multibillion-dollar mass public transit project, intended in part to attract investment and funded by a voter-approved sales tax increase.

In 2003, Hickenlooper announced a ten-year plan to end homelessness in Denver, citing it as one of the issues that prompted him to run for mayor. 280 U.S. cities announced similar plans. The effort did not end homelessness in Denver, and in 2015 Denver's city auditor "released a scathing audit faulting the plan's implementation." The head of the agency responsible defended the program, saying it was "still housing 300-400 people a month in varying ways", while Hickenlooper argued that the point of such an ambitious target was to focus attention and resources on the problem. In his governor's budget request for 2017–18, he asked lawmakers to allocate $12.3 million from taxes on marijuana to building homes for chronically homeless people.

Hickenlooper established the Denver Scholarship Foundation, providing needs-based college scholarships to high school graduates.

In May 2007, Hickenlooper was reelected with 88% of the vote. He resigned as mayor just before his inauguration as governor.

Hickenlooper was an executive member of the Denver 2008 Convention Host Committee and helped lead the successful campaign for Denver to host the 2008 Democratic National Convention, which was also the centennial anniversary of the city's hosting of the 1908 Democratic National Convention.

In a controversial move decried by critics as breaching partisan ethics, the Hickenlooper administration arranged for the DNC host committee, a private nonprofit organization, to get untaxed fuel from Denver city-owned pumps, saving them $0.404 per US gallon ($0.107/L). Once the arrangement came to light, the host committee agreed to pay taxes on the fuel already consumed and on all future fuel purchases. Also, Coors Brewing Company, based in Golden, Colorado, used "waste beer" to provide the ethanol to power a fleet of FlexFuel vehicles used during the convention.

Hickenlooper was viewed as a possible contender for governor of Colorado in the November 2006 election to replace term-limited Republican governor Bill Owens. Despite a "Draft Hick" campaign, he announced on February 6, 2006, that he would not run for governor. Later, he supported Democratic candidate Bill Ritter, Denver's former district attorney, who was subsequently elected.

After Ritter announced on January 6, 2010, that he would step down at the end of his term, Hickenlooper was cited as a potential candidate for governor. He said that if Salazar mounted a bid for governor, he would likely not challenge him in a Democratic primary. On January 7, 2010, Salazar confirmed that he would not run for governor in 2010 and endorsed Hickenlooper. On January 12, 2010, media outlets reported that Hickenlooper would begin a campaign for governor. On August 5, 2010, he selected CSU-Pueblo president Joseph A. Garcia as his running mate. Hickenlooper was elected with 51% of the vote, ahead of former congressman Tom Tancredo, running on the American Constitution Party ticket, who finished with 36.4% of the vote.

Hickenlooper won a tightly contested gubernatorial election with 49% of the vote to Republican businessman and former congressman Bob Beauprez's 46%.

On January 11, 2011, Hickenlooper was sworn in as the 42nd governor of Colorado after winning by 15 points. He was the second Denver mayor ever elected governor. His victory was a landslide despite Democrats' poor results overall in the 2010 elections. Republicans flipped twelve governorships nationwide in 2010. NPR described Hickenlooper as having a "pro-business centrist profile" and as "known to try to build consensus and compromise on tough issues", while 5280 called him as "one of those unicorn-rare, truly apolitical politicians", noting support from business leaders and some Republicans.

On December 4, 2012, Hickenlooper was elected to serve as vice chair of the Democratic Governors Association.

On August 25, 2017, it was reported that Republican Governor of Ohio John Kasich was considering the possibility of a 2020 unity ticket to run against Donald Trump, with Hickenlooper as vice president.

Constitutionally limited to two consecutive terms, Hickenlooper could not run for governor in 2018.

On June 5, 2020, the Colorado Independent Ethics Commission fined Hickenlooper $2,750 for twice violating Colorado's gift ban as governor. Hickenlooper received a flight on a private jet owned by homebuilder and donor Larry Mizel, the founder of MDC Holdings. He also received private security and a ride to the airport in a Maserati limousine on a trip to the Bilderberg Meetings in Italy. The state spent an estimated $127,000 in attorney's fees investigating the violation.

In 2013, a campaign sought clemency for Nathan Dunlap, a black man facing execution for the 1993 murder of four people, with three former jurors saying they would not have voted for the death penalty had they known of his undiagnosed mental illness, while the mother of a victim, a former co-worker of Dunlap, and the Arapahoe County District Attorney urged Hickenlooper to let the execution take place. Hickenlooper granted Dunlap a reprieve, reversible by a future governor, citing inequity in the legal system and the evidence against capital punishment's effectiveness as a deterrent, saying, "It is a legitimate question whether we as a state should be taking lives".

In Hickenlooper's 2016 memoir, he came out against the death penalty, saying his views had changed after he became more familiar with the research showing bias against minorities and people with mental illnesses.

In May 2014, Hickenlooper signed five bills related to disaster relief in the wake of flooding and wildfires. The bills funded grants to remove flood debris from watersheds and to repair flood-damaged schools and damaged wastewater and drinking water systems. They also exempted people who lost homes from having to pay property taxes and out-of-state disaster workers from having to pay Colorado state income tax.

In 2005, Denver voted to legalize possession of small amounts of cannabis, becoming the first major U.S. city to do so. Hickenlooper opposed the initiative as mayor, calling marijuana a gateway drug and saying that the initiative would not prevent enforcement of state law prohibiting cannabis. As governor in 2012, he opposed Amendment 64, which made Colorado the first state along with Washington to allow the sale and recreational use of cannabis. Hickenlooper said the initiative "sends the wrong message to kids that drugs are OK" and that "federal authorities have been clear they will not turn a blind eye toward states attempting to trump those laws". Despite his opposition, he worked with the state legislature to implement the initiative after it passed, and a federal crackdown on sale of the drug never materialized.

As Colorado's new laws were implemented and the results became clearer, Hickenlooper's views evolved. In 2016, he said that Colorado's approach to cannabis legalization was "beginning to look like it might work". In 2019, he said that "the things that I feared six years ago have not come to pass" and that he would be happy to decriminalize cannabis at the federal level if he became president. He also said that the federal government should not stop states from decriminalizing illicit drugs beyond marijuana, as well as allowing for safe, supervised injection sites. In 2022 he introduced the PREPARE Act, to direct the attorney general to develop a regulatory framework for cannabis similar to alcohol, in preparation for federal legalization of the drug.

In March 2014, Hickenlooper signed House Bill 1241, which funded the Rural Economic Development Initiative (REDI).

In 2016, Hickenlooper launched a program called Skillful, with the help of LinkedIn and the Markle Foundation. The program uses online tools and on-the-ground advisors to help businesses create job descriptions to tap into a wider job pool and help job seekers fill high-need jobs and connect them with job training. Twenty other states are now following. In 2017, Skillful added the Governors Coaching Corps. program, a career coaching initiative operated out of workforce center, community colleges, and nonprofits, with the help of a $25.8 million grant from Microsoft.

Hickenlooper calls himself "a fiscal conservative." He has said, "I don't think the government needs to be bigger. I think the government's got to work, and people have got to believe in government, and I think that's part of the problem," and "I think what a lot of Americans want is better government, not bigger government."

Hickenlooper's administration created the first methane-capture regulations for oil and gas companies in the entire country. The rules prevented 95% of volatile organic compounds and methane from leaking from hydraulic fracturing wells. The rules were later used as blueprints for California, Canada, and the federal government's own new rules.

After Trump announced that the United States would leave the Paris Climate Accord, Hickenlooper joined more than a dozen other states in retaining the accord's greenhouse gas emission reduction goals.

NPR has called Hickenlooper a "strong supporter of Colorado's oil and gas industry". Unlike most Democrats, he supports hydraulic fracking, a controversial oil and natural gas extraction process. Before politics, Hickenlooper was a geologist. He believes fracking is a beneficial practice with minimal environmental harm, even testifying in a 2013 hearing before the Senate Committee on Energy and Natural Resources that he had drunk a glass of fracking fluid produced by Halliburton.

In February 2021, Hickenlooper was one of seven Democratic U.S. senators to join Republicans in blocking a ban of hydraulic fracturing, commonly known as fracking.

In September 2023, Hickenlooper introduced the BIG WIRES Act in the United States Senate as S. 2827 alongside Representative Scott Peters, who introduced it in the House of Representatives. The bill's provisions direct the Federal Energy Regulatory Commission (FERC) to "establish minimum interregional transfer capabilities", better coordinating construction of electrical transmission lines. The bill is part of broader push to accelerate permitting for clean energy.

Exactly eight months after the 2012 mass shooting in Aurora, Colorado, Hickenlooper signed bills into law requiring universal background checks on all gun transfers in Colorado except gifts between immediate family members, and banning magazines with more than 15 rounds. Although most Coloradans supported the measures, according to polling by the Denver Post, the bills' opponents gathered enough signatures to trigger special elections leading to the ousting of Democratic state senators John Morse and Angela Giron and the resignation of Evie Hudak.

Hickenlooper was a member of Mayors Against Illegal Guns until 2011. In 2018, he supported a Red Flag or Extreme Risk Protection Order Bill in the legislature that would have allowed judges to temporally restrict firearm access to those deemed a significant risk to themselves or others. The GOP-controlled State Senate never let the bill out of committee that legislative session.

Hickenlooper expanded Medicaid and established Colorado's health insurance marketplace, Connect for Health Colorado, through the provisions of the Affordable Care Act. The state's uninsured rate dropped from 14.3% in 2013 to 6.5% in 2017. Approximately 350,000 Coloradans, about a quarter of whom are undocumented immigrants and thus ineligible for public insurance, remained without insurance coverage. The price of health insurance coverage continued to rise in Colorado, which has some of the highest premiums in the nation.

Hickenlooper is pro-choice on abortion rights. After Roe v. Wade was overturned in June 2022, he said the decision "threatens not just a woman’s physical health & control over her own future, but it also threatens to put women & their doctors in jail", and that "Republicans should join Democrats today and vote to keep politics out of reproductive health care decisions."

As governor, Hickenlooper signed legislation granting in-state tuition to Dreamers (DACA) and joined a lawsuit to stop the Trump administration from ending DACA. During his 2019 campaign for President, Hickenlooper described the Trump administration family separation policy as ″kidnapping″ and said it would be ″crazy″ to deport 11 million undocumented immigrants.

Hickenlooper voted against providing economic support to undocumented immigrants during the COVID-19 pandemic on February 4, 2021.

In March 2019, Hickenlooper said he supported legalizing sex work and regulating "where there are norms and protections".

During his 2020 presidential campaign, Hickenlooper voiced concern about potential monopolistic activity in the tech sector, and identified Amazon and Google as potentially hindering competition. His platform called for revamping the Clayton Antitrust Act of 1914 to clamp down on anti-competitive behavior.

As governor, Hickenlooper set up a Council for the Advancement of Blockchain Technology to coordinate Colorado's approach to blockchain policy.

Hickenlooper's first wife, Helen Thorpe, is a writer whose work has been published in The New Yorker, The New York Times Magazine, George, and Texas Monthly. Before they separated, they lived in Denver's Park Hill neighborhood with their son, Teddy. Upon taking office as governor, Hickenlooper and his family decided to maintain their private residence instead of moving to the Colorado Governor's Mansion. On July 31, 2012, Hickenlooper announced that he and Thorpe were divorcing after 10 years of marriage. After the divorce, Hickenlooper moved into the Governor's Mansion. Hickenlooper married Robin Pringle on January 16, 2016. Pringle and Hickenlooper welcomed a baby boy via surrogate in December 2022.

Hickenlooper is of partial Dutch descent. His mother's family were practicing Quakers. He spent a summer in his teens volunteering with the American Friends Service Committee in Robbinston, Maine, helping establish a volunteer-run free school. In 2010, Hickenlooper told The Philadelphia Inquirer that he and Thorpe attended Quaker meetings and tried to live by Quaker values. In a 2018 speech to the Economic Club of Chicago, Hickenlooper said "I'm not a Quaker", but spoke about the role of Quaker teaching in his approach to government.

A cousin, George Hickenlooper (1963–2010) was an Emmy-winning documentary filmmaker. He is the great-grandson of Civil War Brivet Brigadier General Andrew Hickenlooper and the grandson of federal judge Smith Hickenlooper. Other relatives include pianist Olga Samaroff (née Lucy Mary Olga Agnes Hickenlooper), the first wife of conductor Leopold Stokowski, and great-uncle Bourke Hickenlooper, who served as governor of Iowa and a U.S. senator from Iowa.

Writer Kurt Vonnegut was a friend of Hickenlooper's father. Meeting later in life, Vonnegut offered advice that came to guide Hickenlooper's life: "Be very careful who you pretend to be, because that's who you're going to be." In his 2016 memoir, Hickenlooper mentioned that he watched the 1972 pornographic movie Deep Throat with his mother alongside one of his friends. He later recounted the event during his 2020 presidential campaign.

Hickenlooper is an avid squash player and continues to compete as a ranked player in national tournaments. As of 2019, Hickenlooper's net worth was more than $8 million.

Hickenlooper lives with prosopagnosia, commonly known as "face blindness".
