A new Marquette Law School Poll survey of Wisconsin voters finds former President Donald Trump with 50% and Vice President Kamala Harris with 49% support among registered voters in a head-to-head matchup in the race for president. Among likely voters, Harris is the choice of 50% and Trump the choice of 49%. These results include initially undecided voters who were then asked whom they would vote for if they had to choose.
In a multicandidate race, Harris, a Democrat, is the choice of 45% and Trump, a Republican, 43%. Robert F. Kennedy Jr. received 8%, Libertarian Chase Oliver 1%, Green Party candidate Jill Stein 1%, Constitution Party candidate Randall Terry less than 0.5%, and independent Cornel West less than 0.5%, among registered voters. Among likely voters, Harris gets 46%, Trump 45%, Kennedy 6%, Oliver 1%, Stein 1%, Terry less than 0.5%, and West less than 0.5%.
In the U.S. Senate race, Democratic Sen. Tammy Baldwin is supported by 53% to Republican Eric Hovde’s 46% of registered voters. Among likely voters, Baldwin received 52% and Hovde 47%. These results include initially undecided voters who were then asked whom they would vote for if they had to choose. On the initial question, before that follow-up, Baldwin received 47% among registered voters, Hovde 39%, and 14% say they are undecided.
When the Senate ballot includes independent candidates, Baldwin receives 50%, Hovde receives 44%, Phil Anderson receives 2%, and Thomas Leager receives 2%, among registered voters. Among likely voters, Baldwin received 51% and Hovde 45%, with 2% each for Anderson and Leager.
The survey was conducted July 24–Aug. 1, 2024, interviewing 877 Wisconsin registered voters. The poll was completed before Harris secured the presidential nomination through a virtual roll call of delegates on Aug. 2.
