This was the first Wisconsin Senate election after the 2024 redistricting. Democrats won all five of the most competitive Senate races, flipping four Republican-held seats. Republicans maintained their majority, with Democrats breaking their two-thirds supermajority in the chamber.

After the elections, Republicans entered the 107th Wisconsin Legislature with 18 of 33 seats.^[2]

Background

Redistricting

This election was significantly affected by the legislative maps drawn as a result of the Wisconsin Supreme Court decision in Clarke v. Wisconsin Elections Commission, which declared the previous legislative district map to be unconstitutional on December 22, 2023.^[3] The court was in the process of selecting a remedial plan, when the legislature chose to embrace the remedial map proposal from Governor Tony Evers. Evers signed the plan into law on February 19, 2024.^[4]

Under the new maps, Democrats were expected to gain seats in the Senate, but they were not expected to be able to win a majority because only even-numbered seats were up for election in 2024.^[5][6] Five of the sixteen seats up for election had no incumbents due to the shifting legislative boundaries.^[7] Both parties spent heavily on the competitive races in this cycle.^[8]

Democrats last won a majority of seats in the state senate in the 2012 recall elections, but they last seated a majority of seats in the session following the 2008 elections.

PFAS Legislation

To combat the threat of PFAS contamination, the Wisconsin legislature included $125 million in the state budget. Despite this, Republicans on the Joint Finance Committee (JFC) have refused to release the funds to be used by the Wisconsin Department of Natural Resources (DNR). On April 9, Evers vetoed a piece of legislation which would have created grants to fight pollution due to PFAS chemicals, in explaining his veto, Evers cited the restrictions the legislation would have placed on the DNR to prosecute polluters. Evers also continued calling for the release of the $125 million which was set aside in the budget for combatting PFAS contamination.^[9] In response to Evers' veto, JFC members said they would hold the funds hostage.

On April 16, Evers called the JFC to session, but its Republican members refused to attend, denying the committee a quorum to do business.^[10] In response to this inaction, Wisconsin Democrats launched a six-figures campaign called "No More Games" which served the purpose to pressure and target members of the Committee from competitive districts. Among their targets were Senate Republicans Joan Ballweg, Howard Marklein, Duey Stroebel, and Eric Wimberger, from the 14th, 17th, 20th and 30th districts respectively.^[11]

In years past, the 8th district was strongly Republican, voting for Republicans by double digit margins, but over time the Milwaukee suburbs and surrounding communities have become more liberal due to the election of Donald Trump in 2016, which saw the 8th district give Trump around 56% of the vote.
