evidence: As has been the case for more than two decades of Pew Research Center surveys, women are significantly more likely than men to associate with the Democratic Party. While the gender gap has changed little in recent years, it is as wide as it has been at any point during this period: Among registered voters, 56% of women affiliate with or lean toward the Democratic Party, compared with 44% of men. From 2010 through 2015, about half of women (51%-52%) identified with or leaned toward the Democratic Party. But the share of women who identify with or lean to the Democratic Party has risen in recent years, to 54% in 2016 and 56% in 2017. The partisan breakdown of men is relatively unchanged over this period. The Democratic gains among women have not come from increased affiliation with the party. Overall, the proportion of women voters who identify with (rather than lean toward) the Democratic Party has remained relatively constant for the past 25 years (in 1994, 37% of women said they identified with the Democratic Party, compared with 39% in 2017).
