Vice President Kamala Harris has closed the polling gap with former President Donald Trump among Wisconsin voters, according to polls taken since President Joe Biden dropped out of the race.

“What we’re seeing is that voters under the age of 50, independents and ethnic minorities, especially African American voters, are swinging back towards the Democratic party,” said Matt Taglia, a senior director at Emerson College polling.

Emerson’s poll is one of several that show Harris leading Trump when voters are asked to choose between the two. A survey conducted July 22-23 showed Harris leading Trump 51-49, within the poll’s margin of error.

When other candidates were included in the question, Harris and Trump were tied 45-45, with independent candidate Robert F. Kennedy Jr. getting 3 percent support and Green Party candidate Jill Stein at 1 percent.

“She changed the dynamics of the race substantially. She moved five points in the margin in Wisconsin, and so I don’t think we necessarily need to wait to see what changes are taking effect as a result of Harris on the ticket,” Taglia said.

Still, with an expected vice presidential announcement in the next several days and the Democratic National convention in less than two weeks, he said it will take some time to get a firmer sense of how the race has changed.
