Democratic Rep. Jenna Jacobson Will Challenge Top GOP State Senator

With the Wisconsin state budget completed just last week, Senate Democrats are gearing up for 2026 elections and their shot at a majority. Rep. Jenna Jacobson (D-Oregon), surrounded by a group of current Democratic senators, launched her campaign Monday for Senate District 17, currently represented by one of the Senate Republicans central to shaping Wisconsin’s budget.

There are about 16 months until November 2026 when half of the state Senate, the entire state Assembly and the governor’s seat will all be up for election. This will be the first time the new legislative maps adopted in 2024 will be in place for the 17 odd-numbered Senate seats.

Democrats gained four seats in the Senate in 2024 — breaking the GOP supermajority and leaving Senate Republicans with a margin of 18-15 majority. They will need to win at least three seats if they are to win the majority for the first time in more than 15 years.

Sen. Howard Marklein (R-Spring Green), the co-chair of the powerful budget committee, is the incumbent, having first been elected to the seat in 2014 after serving two terms in the Assembly.

Lisa White, a Democrat who runs an interior painting business, is also running for the seat.

Jacobson, who is serving her second term in the Assembly, told the Wisconsin Examiner that she is challenging Marklein in part because he hasn’t been listening.

Marklein won the district with 60% of the vote in 2022, but Senate District 17 changed considerably under the new maps. According to an analysis by John Johnson, a research fellow at Marquette University, the district leaned Democrat by 1 percentage point in the 2024 presidential election and by over 4 percentage points in the 2024 U.S. Senate race.

“The biggest thing that I see about this district is that people really want somebody who’s going to represent what they’re fighting for, what they need and listen to them, and even listen to them when they don’t necessarily agree,” Jacobson said. “They’ve been not receiving that in their current state senator.”

Jacobson cited a report in the Monroe Times of a Marklein listening session in Belleville in January — coincidentally on the same day that Jacobson was holding one there.

“There was a list of rules of what would and will not be happening in that listening session,” Jacobson said. “That, to me, is the starkest example of what it means to listen to your community, because I was inviting anybody… there are no rules. I’m open to having a conversation with anybody at any time.”

Marklein’s notice told residents that it was “designed for the senator to receive input and ideas about issues facing residents in the 17th Senate District” and he didn’t “plan to answer questions, debate ideas, challenge the ideas, or otherwise comment because he is seeking to hear every point-of-view equally.” The notice said that “the goal is for every attendee to feel comfortable sharing their input.” It also advised those attending that  their comments might be subject to a time limit.

Jacobson launched her campaign outside an elementary school in Ridgeway that was closed after the Dodgeville school district combined two elementary schools into one. She called Marklein a “classic politician” who she said has “failed” the Senate district.

“Our district has time and again been forced into referenda to fund our schools because Howard Marklein has chosen power over people,” Jacobson said. “He has chosen ideology over voting for the needs of the district. That is irresponsible governing.”

Jacobson first ran for the state Assembly for an open seat in 2021 and said her service on the Oregon village board showed her how local government intersects with state government and why it’s important to shape the latter.

Her announcement came less than a week after lawmakers and Gov. Tony Evers completed the state budget. The Republicans’ narrower Senate majority led to a new dynamic during the budget process. With Democratic votes necessary to pass the bill, Minority Leader Dianne Hesselbein (D-Middleton) became involved in budget negotiations.

Hesselbein joined Jacobson at her campaign announcement Monday, along with Sens. Kelda Roys (D-Madison), Mark Spreitzer (D-Beloit), Dora Drake (D-Milwaukee) and Brad Pfaff (D-Onalaska).

Jacobson has been fighting for public school funding, Hesselbein said. “In the Senate, she will dedicate herself to lowering costs for your families, to creating a bright future for your children, and making our state stronger every day,” Hesselbein said. “We are excited and proud to be standing behind her in this campaign and we look forward to her joining us and helping us win a Democratic majority.”

Jacobson voted against the budget, joining 37 other Assembly Democrats.

Democrats credited the new maps and the Senate’s closer margins for the budget agreement, which included an increase in funding for special education, the University of Wisconsin system and child care. The bill passed thanks to five Senate Democratic votes, although a recurring theme among Democrats whether they voted for or against the budget, including Jacobson, was that it wasn’t perfect.

Jacobson said that was part of the reason she launched her campaign.

“I was hoping under these new maps — with even more voices talking so loudly about the fact that they need state assistance when it comes to affording child care, they need more funding for our schools, they need real help on the everyday costs that are facing Wisconsinites — that under this new more competitive district that would be represented in the state budget,” she said. “What we’re seeing is that the cycle of referendums is not going to end under this budget… and that was a missed opportunity in this budget.”

During the final discussions over the budget, Marklein emphasized that the document was a “compromise” between Republicans and Democrats while highlighting items affecting his district, such as funding for the UW system that would help the Platteville campus. Marklein did not respond to an email from the Wisconsin Examiner on Monday asking about his 2026 plans and his response to Democrats targeting SD 17.

Jacobson said she doesn’t view Marklein’s long tenure as a state lawmaker as a challenge. She said she is more concerned with the size of the Southwest Wisconsin Senate district, which encompasses Iowa, Lafayette, Green, Crawford and Grant counties as well as parts of Dane County.

“It’s a big district, but the benefit of that is that it’s filled with these amazing rural communities that when people think about Wisconsin that’s what they think of…,” Jacobson said. “Sure [Sen. Marklein has] been an incumbent for a while, but has he been out? How much is he doing outside of walking a parade to really listen to the district?”

Jacobson, a mother of three children, said public education funding will be one of her top issues, though she is also more concerned about hearing from others. She said she has been traveling the district over the last few weeks and hearing an array of concerns from residents.

“They’re concerned that they’re going to have to have more referenda because of the lack of school funding to increase their property taxes even more,” Jacobson said. “They’re concerned that without meaningful work or support from the state — our health care system in that area… seven hospitals… multiple clinics — those are going to potentially be in jeopardy.”
