Below is a selection of public opinion polls showing presidential preference in the state of Colorado; we have highlighted survey findings on gender.
The gender gap is the difference in the percentages of women and men who support a given candidate — the gap between the genders, not within a gender. Even if women and men favor the same candidate, they may do so by different margins, resulting in a gender gap.
* We calculate the gender gap for each poll based on the votes of women and men who support the candidate leading in that poll.
