Vice President Kamala Harris has changed the face of the upcoming presidential election, but she also appears to be changing the face of this year’s electorate.

A pattern has existed for decades: When Democrats win the presidency, it is usually because of their support among women. With Harris in the race, the electorate is likely to be younger, more female and more supportive of abortion rights than it would have been with President Biden as the Democratic nominee, polls have found. In the eight days after Biden withdrew from the race and tapped Harris, the motivation to vote among people in five battleground states jumped 42 points. The shift in enthusiasm was even greater among women, but Harris maintained Biden’s level of 37 percent support among men too.
