United States Senate election in Colorado, 2008

The Colorado U.S. Senate Election of 2008 was held on November 4, 2008. The election featured an open contest because incumbent Senator Wayne Allard declined to seek re-election. He honored his 1996 pledge to serve no more than two terms in the U.S. Senate and announced that he will retire from his service to the US Senate and not seek a 3rd term, leaving Colorado's Class II Senate seat open. Both parties believed this senate contest would be one of the most competitive senate races during the 2008 election.{{cite web|url=http://thecaucus.blogs.nytimes.com/2008/06/13/gop-leader-maps-senate-elections/#more-5357|title=G.O.P.
