An unusually high number of the state's registered Republicans and Democrats took time to vote in last week's election.
The Denver Post reports in today's editions that nearly one-third of voters registered with either party turned out for the August 10th primary.
The Post reported 32 percent of Republicans voted, while turnout for Democrats was 27 percent.
Political analysts credit Colorado's U-S Senate race for the high turnout, and say it likely helped businessman Pete Coors defeat former U-S Representative Bob Schaffer in the Republican primary.
Coors will face Colorado Attorney General Ken Salazar in November.
Salazar campaign manager Jim Carpenter says Democrats will have to work harder to get independent and Republican voters.
