Colorado has remained simply red on the election map, with voters choosing George Bush for president and rejecting a proposal to split the state's nine Electoral College votes.
But the Republican's presidential coattails weren't long enough to carry Republican businessman Pete Coors into the United States Senate.
Democratic Attorney General Ken Salazar defeated Coors in a bitterly fought race to replace retiring GOP Senator Ben Nighthorse Campbell.
That makes Salazar the first Democrat elected to statewide office in ten years, and the first Hispanic U.S. senator in more than 25 years.
Meanwhile, Massachusetts Senator John Kerry became the ninth Democrat to lose in Colorado in the past ten presidential elections.
