Motivation to vote surged among women after Harris became the nominee

When considering how the presidential election is likely to turn out, there is no more important question than who will be motivated to cast a ballot. All of the talk of Vice President Kamala Harrisâ€s and former president Donald Trumpâ€s efforts at persuading undecided voters is interesting but not terribly relevant. Instead, given the likelihood of the presidency being determined by narrow margins in a handful of states, the central issue is whose base of support shows up at the polls.

That question overlaps with the other defining aspect of the contest: that men and women appear to be unusually polarized on vote choice. Trump is running a campaign explicitly focused on getting more men (particularly young men) to vote. Harris, by contrast, is depending on women, often letting the historic nature of her bid serve as an implicit appeal.

But the 2024 election is also the first presidential contest to unfold in the post-Roe v. Wade world. In 2022, Democrats overperformed expectations in the midterms, an outcome attributed at times to turnout shifts driven by views on abortion access. In special elections — and particularly on ballot initiatives centered on abortion — abortionâ€s role has been more explicit.

New polling from KFF reinforces the advantage Harris has both with women and on the issue of abortion. The pollsters went back to women they had interviewed in June, evaluating how their views of the race had shifted since Harris became the Democratic nominee.

Perhaps the most important shift appeared in the extent to which women expressed more motivation to vote than they usually felt. Overall, the percentage of women saying they were more motivated than normal jumped nearly 20 points, driven by a big surge among Democratic women. Democratic women were also far more likely to describe themselves as satisfied with the candidates for president than they were in June.

Relative to June, women were also more likely to say that the election would have a big impact on the issue of abortion. In fact, KFF found that women — including Republican women — thought it was likely that Trump would sign a national ban on abortion (should it come to his desk if he won in November) and that Harris would sign a law codifying the protections of Roe.

Certainly some Republican women would see a national abortion ban as good and abortion protections as a negative. Two-thirds of women, though, oppose such a ban. (Trump has said he wouldnâ€t sign a national ban, but his running mate, Sen. JD Vance (R-Ohio) endorsed a “minimum standardâ€� during the vice-presidential debate earlier this month.)

Thereâ€s an important aspect to the turnout question that is worth mentioning. There are more women in America than men, and women usually make up more of the electorate than do men. But that wasnâ€t the case in 2022, according to analysis conducted by the Pew Research Center. More importantly, women made up the majority of nonvoters in 2018, 2020 and 2022.

Those nonvoters were disproportionately non-White. KFFâ€s research shows that Black and Hispanic women are more likely now than in June to say theyâ€re satisfied with the presidential candidates — and more likely to say so than White women. But White women are more likely to say they feel more motivated to vote than usual.

Voters are notoriously bad at predicting whether they will actually vote. Harrisâ€s team, though, can pick out patterns here that comport with what it would want to see: a highly motivated base of women who see a sharp divide between the candidates on the issue of abortion access. It just needs to hope that the increase in motivation correlates to an increase in turnout.
