Eighty percent, or more than 2 million, Coloradans voted early, mostly by mail. Only 532,000 showed up on Election Day.
Among active voters, there was 97 percent turnout and more than two-thirds (71%) of total registered voters voted.
Republican and Democratic registration was nearly tied, with only 42,000 more Republicans showing up (the party list voters will not be final until Dec. 6). Unaffiliated voters made up 31 percent of the total.
In light of the Democratic presidential win, some Republicans and many unaffiliated voters supported President Obama.
