The latest poll also found that 56% of Americans have a favorable impression of Harris, which is about the same as the number who favor Biden. Forty-two percent of U.S. adults say they have a favorable view of Trump and 47% said the same of Pence.

Among women, 60% said they have a favorable view of Harris, compared with 53% who felt the same way about Biden. Women are the dominant force in American elections: they make up a bigger proportion of the U.S. electorate than men, and a surge in support for Democrats among white, college-educated women helped the party retake the U.S. House of Representatives in 2018…

In addition, about 25% of Republicans said they had a favorable view of Harris and approve of her choice as Biden’s running mate. Only about 20% of Republicans said they have a similarly favorable view of Biden.

In a close election, peeling off even a small number of voters from the Republican Party could make a difference to the Democrats, political analysts said.
