Candidates, Wisconsin Statewide and Federal Elections


The race for Wisconsin governor is getting more crowded on the Democratic side. So far, five have officially entered the Democratic primary, and two other possible contenders have set up campaign committees.

Here’s an updated list of announced candidates for statewide and federal elections in Wisconsin in 2018. While formal announcements by incumbents from governor to Congress are so far few and far between, it’s generally expected that most incumbents will run for re-election. We will update this list as formal announcements start rolling in.

State Races

By throwing her hat in the ring for U.S. Senate, Sen. Leah Vukmir will give up her seat representing the 5th Senate District. Rep. Dale Kooyenga (R-Brookfield) has announced his candidate to replace Vukmir. Barring a surprisingly strong primary challenger, the good money is on Kooyenga taking the 5th S.D.

That leaves Kooyenga’s 14th Assembly District seat up for grabs. No one has announced their candidacy for it yet, but possible candidates are current state Treasurer Matt Adamczyk, whose family owns property in the district; Johnny Koremenos, who runs communications for the Attorney General’s office; and Luis O. Cardona, who served in the U.S. Army with Kooyenga and currently works for Rep. Shannon Zimmerman.

On the other side of the state, Mel Pittman has officially reprised his 2014 bid for the 31st Senate District. His announcement came days before Vinehout’s announcement in Black River Falls that she’d run for governor. It’s worth noting that Vinehout only defeated Pittman in 2014 with 52.4 percent of the vote, the 31st went heavily for Donald Trump in 2016, and the only incumbent Democrat to lose their seat in 2016 was Chris Danou, whose district is within the S.D. 31.

With Pittman the heir apparent in S.D. 31, it’s unclear who the Democrats could put up in Vinehout’s stead. The notoriously party-blind region of the state could go either way despite its lurch toward Trump, but the highest-profile elected Democrat in the district with Danou out is Rep. Dana Wachs (D-Eau Claire), who is also running for governor.

Rumors are also circulating that Sen. Sheila Harsdorf might be under consideration to run the state’s Department of Agriculture, Trade and Consumer Protection (DATCP). If that happens, her senate district (S.D. 10) would be an open seat. An early potential contender is Rep. Adam Jarchow (R-Balsam Lake), but freshman Rep. Shannon Zimmerman – a successful businessman who could potentially finance a senate race in that expensive media market – is another possibility. Rep. Rob Stafsholt (R-New Richmond) rounds out representatives in S.D. 10.

Some in the media may try and portray Harsdorf’s district as a possible pick-up for Democrats, but that’s unlikely. In her last election in 2016, Harsdorf annihilated her Democratic opponent, Diane Odeen, with 63.22 percent of the vote.
