The2006 Colorado gubernatorial election was held on November 7, 2006. Incumbent Republican governorBill Owens was unable to run due to term limits, and the election was won by Democratic nomineeBill Ritter.
With his win, Democrats obtained a trifecta in the state for the first time since 1963. As of 2026, this is the last time the Governor's office in Colorado changed partisan control.
In the leadup to the Democratic primary,Bill Ritter, the formerDistrict Attorney of Denver, emerged as the leading Democratic candidate. Though several other prominent state Democrats, including Denver MayorJohn Hickenlooper[1] and State House SpeakerAndrew Romanoff,[2] considered running for Governor, both ultimately declined to do so. State Representative Gary Lindstrom, the only other candidate besides Ritter in the race, ended his campaign on February 28, 2006.[3] Ritter's personal opposition to abortion motivated pro-choice leaders in the state party to seek alternatives to him,[4] but none ultimately materialized, and opposition to Ritter softened with his pledge to not alter the state's liberal abortion laws.[5]

With popular two-term GovernorBill Owens barred from seeking re-election, an open race developed for the Republican nomination to succeed him. The race looked like it would be between CongressmanBob Beauprez, who represented the swingy Denver suburbs in Congress, and formerUniversity of Denver PresidentMarc Holtzman. The race between Beauprez and Holtzman was contentious. Beauprez accused Holtzman of ethics violations, including making false allegations that the campaign's email list was stolen,[7] providing falsified poll results to theDenver Post, and using a separate state campaign committee as a "shadow gubernatorial campaign."[8] Holtzman, meanwhile, accused Beauprez of being part of the "politics of power" that he argued had taken the party away from its conservative values, pointing to Beauprez's support of Referendum C in 2005, which allowed the state to hold onto excess tax revenues rather than refund surpluses.[9]
In the end, the campaign between the two frontrunners fizzled. Beauprez won a landslide victory at the state Republican convention, denying Holtzman a spot on the ballot. Holtzman's efforts to collect signatures to win a spot on the ballot were ultimately in vain, with theColorado Supreme Court ruling in June that he had failed to submit enough signatures. In response, Holtzman suspended his campaign and endorsed Beauprez, who won the Republican primary unopposed.[7]
