2004 United States Senate election in Colorado

The 2004 United States Senate election in Colorado took place on November 2, 2004 alongside other elections to the United States Senate in other states as well as elections to the United States House of Representatives and various state and local elections. Incumbent Senator Ben Nighthorse Campbell (first elected in 1992 as a Democrat and re-elected in 1998 as a Republican, having switched parties in 1995) retired instead of seeking a third term. Democratic nominee Ken Salazar won the open seat, defeating Republican nominee Pete Coors despite Republican President George W. Bush carrying the state over John Kerry in the concurrent presidential race.

U.S. senator before election Ben Nighthorse Campbell Republican Elected U.S. Senator Ken Salazar Democratic

Background

On March 3, 2004, incumbent Republican Senator Ben Nighthorse Campbell announced that he would not seek reelection due to health concerns, having recently been treated for prostate cancer and heartburn.^[1] Before Campbell's retirement, no prominent Democrat had entered the race, with educator Mike Miles and businessman Rutt Bridges pursuing the Democratic nomination. After Campbell's retirement, many expected popular Republican Governor Bill Owens to enter the race,^[2] however he declined to run. Campbell's retirement and Owens' decision not to run prompted a number of prominent Democrats to reexamine the race.^[3]

Democratic primary

Candidates

• Ken Salazar, Attorney General of Colorado
• Mike Miles, educator

Campaign

On March 10, the same day Owens announced he would not run, U.S. Congressman Mark Udall entered the race.^[4] The next day, state Attorney General Ken Salazar entered the race,^[5] leading Udall to immediately withdraw and endorse him; Udall held Colorado’s other Senate seat from 2009 to 2015.^[6] Salazar lost to Mike Miles at the State nominating convention. In spite of this loss, the national Democratic Party backed Salazar with contributions from the DSCC and promotion of Salazar as the only primary candidate.^[7]

Bob Schaffer

Elected officials

Campaign

The two candidates got into an ideological battle, as Schaffer attacked Coors because his company had provided benefits to the partners of its gay and lesbian employees, in addition to promoting its beer in gay bars. Coors defended himself by saying that he was opposed to same-sex marriage and supported a constitutional amendment to ban it, although he noted that he supported civil unions for gay couples. According to the Rocky Mountain News, Coors described his company's pro-LGBT practices as "good business, separate from politics."^[13]
