About this Poll
The Denver Post's poll by SurveyUSA was conducted Sept. 8 through Sept. 10 of 850 Colorado adults and narrowed to 664 likely voters. SurveyUSA contacted both land lines and cell phones.

The poll results have a margin of error of plus or minus 3.9 percentage points. Pollsters weighted the sample by gender, age, race and region, but not by party identification. The party affiliation breakdown of the sample, with numbers rounded, was 33 percent Republican, 33 percent Democratic and 33 percent unaffiliated.
