Harris is up three points, 50% to 47%, in a Washington Post-Schar School poll of likely voters released Monday (margin of error 4.6).

Harris leads Trump by a narrow 0.2 points in the state, according to Five Thirty Eight’s polling average, while Sept. 28-Oct. 8 Wall Street Journal poll showed them tied at 48% among registered voters who said they would “probably” or “definitely” vote for either candidate.

An Emerson College/The Hill survey released Oct. 10 also found Trump and Harris tied at 49% in Wisconsin, and a Quinnipiac poll out Wednesday showed Trump up by two points, 48% to 46%.

A Marquette Law School poll released Oct. 2 found Harris up six points over Trump in the state and that enthusiasm for voting has ticked up sharply, with 67% of respondents saying they are “very” enthusiastic, compared to 46% who said so in June; enthusiasm among Wisconsin Democrats is slightly higher, with 71% saying they are very enthusiastic and 67% of Republicans saying they’re very enthusiastic.

Voter turnout in Wisconsin could be high in November as there are several competitive U.S. House races in the state on the ballot and Republicans are in a tight contest to maintain majority control of the state Assembly, Anthony Chergosky, an assistant professor of political science at University of Wisconsin-La Crosse told WUWM public radio in Milwaukee.

Waning support for Democratic Sen. Tammy Baldwin in the Wisconsin Senate race is also seen as a warning sign for Democrats as Cook Political Report moved the state from lean Democrat to a toss-up last week after finding her lead over Republican Eric Hovde has shrunk from seven points to two since August, though a Marquette Law School poll, also released last week, still found her with a seven point advantage.

Biden won Wisconsin by less than one point in 2020, flipping the state after Trump beat Hillary Clinton there in 2016; former President Barack Obama won the state by decisive margins in both 2008 and in 2012.
