Here's who's ahead in Wisconsin polls for the 2024 presidential election

Most polls in Wisconsin – whose 10 electoral votes could prove decisive – reflect a razor-thin race, with Harris leading by just one point in the FiveThirtyEight weighted average.

Harris and Trump are tied at 49% (margin of error 3.4 points) in the latest Emerson College/The Hill poll on Monday.

Harris is leading likely voters 49-47% (margin of error 3.5 points) in the latest pre-election New York Times/Siena swing state poll released Sunday, despite Trump in a Morning Consult Poll has a lead of about a point rounds up to about 48-48%.

In a Marist poll released Friday of likely voters, which includes undecideds leaning toward a candidate, Harris is ahead 50-48% (margin of error 3.4 points), and she is tied in a Marquette Law School poll 50-49% ahead among likely voters The poll released Wednesday (margin of error 4.4 points) also includes undecided voters leaning toward one of the candidates – showing Trump overtaking the six-point lead Harris had in the last poll The school's survey published on October 2nd has decreased significantly.

In a CNN/SSRS poll also released Wednesday, Harris has a larger lead of 51% to 45% (margin of error 4.8 points), and she has a lead in a Cooperative Election Study poll released last week from 50% to 47% ahead of Trump, part of a national study of universities conducted by YouGov (1,542 respondents).

Voter turnout in Wisconsin could be high in November as the state faces several closely contested U.S. House elections and Republicans wage a tough battle for majority control of the state legislature, said Anthony Chergosky, an assistant professor of political science at the University of Wisconsin-La Crosse told WUWM Public Radio in Milwaukee.

Dwindling support for Democratic Sen. Tammy Baldwin in the Wisconsin Senate race is also seen as a warning sign for Democrats, as Cook Political Report last week turned the state from a lean Democratic state into a contender after finding her lead ahead Republican Eric Hovde has shrunk by seven points to two since August, although a Marquette Law School poll also released last week showed her still with a seven-point lead.

Biden won Wisconsin by less than a point in 2020, flipping the state after Trump defeated Hillary Clinton there in 2016; Former President Barack Obama won the state by significant margins in both 2008 and 2012.
