New maps help Wisconsin Democrats make legislative gains and set up a push for majorities in 2026

MADISON, Wis. — Democrats came out of Tuesday's elections with substantial gains in the Wisconsin Legislature under new district boundaries, setting them up for a run for a majority in two years.

Democrats had high hopes that the maps would enable them to seize control of the state Assembly for the first time in 13 years. That didn't happen, but their wins still stood out given that Republican President-elect Donald Trump carried Wisconsin.

“Thanks to fair maps and a smart strategy, the GOP's stranglehold on Wisconsin's legislature is coming to an end,” Heather Williams, president of the Democratic Legislative Campaign Committee, said in a statement. The DLCC is the arm of the Democratic Party tasked with building majorities in state legislatures.

Republicans took control of the Senate and Assembly in 2011. Democrats used recall elections to win a Senate majority for six months in 2021, but otherwise the GOP has controlled both houses since then thanks largely to gerrymandered district maps that spread out Democratic voters.

Liberal justices who took control of the state Supreme Court last year tossed out the maps, clearing the way for Democratic Gov. Tony Evers to enact new boundaries. Democrats made no secret on the campaign trail this summer that they thought the new boundaries would translate to control of the state Assembly and help them flip enough Senate seats that they'd have a shot at a majority in that chamber in 2026.

The plan mostly worked. Democrats failed to take control of the Assembly, but unofficial results Wednesday showed they had flipped 10 Republican seats, narrowing the GOP's edge from 64-35 last session to 52-44 with four races still undecided.

Eight of the seats the Democrats converted were open thanks to retirements and the new maps. They also defeated two Republican incumbents — Tom Michalski, who represented Milwaukee's western suburbs, and Loren Oldenberg, who represented a section of a far western Wisconsin south of La Crosse.

“Flipping a legislative body isn’t easy, but we have fundamentally shifted the status quo in the legislature and set the stage for more progress in the future,” Assembly Democratic Minority Leader Greta Neubauer said in a statement Wednesday. "Our work continues.”

Republican Assembly Speaker Robin Vos didn't immediately respond to messages from The Associated Press. He planned to hold a news conference at the state Capitol later Wednesday.

On the Senate side, Democrats had managed to flip three Republican seats as of midday Wednesday.

Counselor Sarah Keyeski ousted GOP incumbent Joan Ballweg in south-central Wisconsin. Green Bay Water Commission Vice President Jamie Wall defeated Republican Jim Rafter in a battle for an open seat in northeastern Wisconsin. Republican Eric Wimberger had held the seat since 2021 but the new maps drew Wimberger into a different district. He won that seat on Tuesday night. Appleton Common Council member Kristin Alfheim defeated Republican physician Anthony Phillips to win an open seat in the Fox Valley that the GOP had held since 2013.

Republican Sen. Duey Stroebel conceded defeat to Democrat Jodi Habush Sinykin on Wednesday morning in a battle for an open seat representing Milwaukee's northern suburbs. The Associated Press had not called the race as of Wednesday afternoon.

Republicans have held that seat since 1993. Stroebel had represented an adjoining district but the new maps pushed him into the open district.

All that narrowed the Republican advantage in the Senate from 22-11 to 18-14 with the Stroebel-Sinykin race still undecided.

The Democratic gains erased the GOP's supermajority in the chamber, ensuring that Republicans won't have enough votes to override any Evers vetoes when the next legislative session begins in January. They also put Democrats within striking distance of a majority in two years.

Senate Democratic Minority Leader Diane Hesselbein did not immediately respond to an interview request.

Republican Senate Majority Leader Devin LeMahieu attributed the Democrats' gains to the new maps and huge spending. Candidates and the four legislative campaign committees alone raised almost $16 million during just the first six months of 2024, according to government watchdog group Wisconsin Democracy Campaign. As of early October, independent groups had spent nearly $2 million in the Wall-Rafter race and nearly $1 million in the Keyeski-Ballweg race, according to Wisconsin Democracy Campaign.

LeMahieu also accused Democrats of distorting Republicans' records on birth control and in-vitro fertilization.

“It's disappointing,” he said. “The good thing is Trump won Wisconsin. Republicans still have a winning message. I still think a majority of voters favor Republicans. We'll roll up our sleeves and continue to fight for what's important for Wisconsin.”

He said the GOP is already planning for the 2026 elections.

“2026 is a long way away, but we'll have some good incumbents running who will have two more years to get to know their constituents,” LeMahieu said. “We'll see. First we have to start a new session and make sure we govern responsibly.”

Republican Donald Trump won Wisconsin in Tuesday's elections but state Democrats still made substantial gains in the state Senate and Assembly to set up a push for majority control in 2026.

New legislative district boundaries didn't pay off quite as well as Wisconsin Democrats had hoped in Tuesday's elections, but they did help the party set up a push for the majorities in 2026.

Republicans have controlled the state Senate and Assembly for most of the last 13 years thanks largely to gerrymandered district lines that concentrated GOP supporters while spreading out Democratic constituents.

The GOP has used those majorities to reshape
