Sen. André Jacque (R-New Franken) announced Monday he’ll retire from office at the end of his term. 

Jacque’s decision means a third of the Republican Senate caucus is not seeking reelection, including Sen. Rob Hutton (R-Brookfield) and Sen. Van Wanggaard (R-Racine), who both represent key districts that will determine control of the body in November, as well as Senate Majority Leader Devin LeMahieu (R-Oostburg).

“My passion for serving our community has not waned, but after much discussion with family and friends I have decided that I will not be seeking re-election to the State Senate this fall,” Jacque, 45, said in a statement.

The wave of retirements comes in an election year where odd-numbered Senate seats will be up for election for the first time under the legislative maps that were adopted in 2024. There are also eight Republicans who have so far announced their retirements. 

Jacque has represented Senate District 1 since 2019. The solidly-red district under the maps adopted in 2024 encompasses Door and Kewaunee counties as well as parts of Calumet, Brown, Manitowoc and Outagamie counties. After the new maps were adopted, Jacque ran in the GOP primary for Wisconsin’s 8th Congressional District, losing to U.S. Rep. Tony Wied, who received the endorsement of President Donald Trump in the three-way primary.

Jacque said he is not sure what he will do after leaving the Legislature, but “this is not farewell — there is still much to be done and I will always work for a brighter future for our state and the advancement of those worthy ideas that never quite made it all the way through the legislative process.” He added  that he has been “greatly blessed, and God’s not done with me yet.” 

Democrats will have the chance to win control of the Senate for the first time since the 2009-11 legislative session. State Senate Democratic Campaign Committee spokesperson Will Karcz said in a statement that the Republican caucus was “retiring en masse to avoid losing at the ballot box in November.” 

“While Republicans jump off their sinking ship, Senate Democrats are focused on the issues that Wisconsinites care about and are making it clear they have a plan to deliver results when they win a majority in November,” Karcz said. 

Jacob VandenPlas, a combat veteran, farmer and former leader of DC Farm for Vets, a veterans nonprofit, announced his campaign for Jacque’s seat on April 17.

Independent Mark Becker is also running for the seat. Becker, a small business owner, was formerly the chair of the Brown County Republican Party. He has hosted a podcast on Civic Media called “Rational Revolution” since 2024, though he has stepped away from that to campaign.
