This year’s state Senate election-year math — 16 Senate seats to be filled on Nov. 5, and no incumbents in five of them — has both parties gearing up for what could be the most expensive legislative elections ever.
Wisconsin Democrats, who held only 11 seats in the 33-member Senate last session, are excited about the chances of winning some of those five open districts.
"For the first time in over 20 years, Senate Democrats have a candidate running in every single district this November,” Senate Democratic Leader Dianne Hesselbein told reporters last week. “We are fired up and ready to go.”
The Associated Press reported that Wisconsin Democrats plan to spend $7 million in television ads in five key state Senate races. “I would be stunned if this were not the most expensive state legislative election cycle in Wisconsin history,” Democratic Party Chair Ben Wikler told reporters.
For their part, Republican senators promised Monday to override five vetoes by Democratic Gov. Tony Evers — an attempt to draw sharp pre-election differences with Democratic candidates in November. Assembly Republicans do not have the two-thirds majority needed to override Evers vetoes, however.
Republican Sens. Howard Marklein and Joan Ballweg said the vetoes that will be overridden include how Republicans want to spend $125 million to fight PFAs water contamination statewide, $15 million to fight Chippewa Valley hospital and clinic closings, and a bill requiring the setting of a wolf hunt quota. The Senate will meet Tuesday.
“Unfortunately, the governor has chosen to veto a lot of these bills that would have fixed a lot of these issues,” Marklein said.
But Marklein, co-chair of the Legislature’s budget committee, said Senate Republicans had not coordinated their veto override plans with Assembly Republicans. He said he “can’t control” how Assembly Republicans will respond to the Senate override votes.
One aspect of the fight for Senate control is interesting: It will take two elections — on Nov. 5 of this year and in November 2026 — to finally elect the state senators in all 33 new districts that Evers and Republicans finally agreed to last year.
It will take two elections because Article 4 of Wisconsin’s Constitution requires alternating elections of the 33 senators, each of whom serve four-year terms. It works this way: senators from even-numbered districts are elected one year, and senators from odd-numbered districts two years later.
“All 16 even-numbered districts will be filled at the Nov. 5, 2024, election,” said Laura Felone, an analyst for the nonpartisan Legislative Reference Bureau that advises lawmakers. “Odd-numbered districts were last elected in 2022, so all 17 of these districts will be filled at the November 2026 election…[Those] 17 senators keep their seats, despite some district overlap.
“This pattern continues each time redistricting occurs, which does mean there is a slight overlap in territory between some districts as we transition between map plans,” Felone added.
This year, that transition means there are five even-numbered new Senate districts with elections in November with no incumbent senators.
Senate districts without incumbents are:
*District 2: Portions of Brown, Outagamie, Waupaca and Shawano counties. Republican Sen. Eric Wimberger, who now lives in Green Bay, has said he will move into the new District 2. That gives Wimberger “sort of an incumbent status,” Felone noted.
*District 4: Portions of the city of Milwaukee and the county’s northwest suburbs. The old District 4 seat has been vacant since Evers appointed former Democratic Sen. Lena Taylor a Milwaukee County Circuit Court judge.
*District 16: Part of the city of Madison and eastern Dane County suburbs. The current District 16 senator, Democrat Melissa Agard, is running for the job of Dane County executive.
*District 18: Portions of Fond du Lac and Winnebago counties. The current District 18 senator, Republican Dan Feyen, is running in the new 20th District.
*District 28: Milwaukee suburbs of New Berlin, Muskego in Waukesha County, and southern suburbs of Milwaukee County. The current District 28 is represented by Republican Julian Bradley.
According to the Wisconsin Democracy Campaign, three Senate elections had more than $3 million spent by candidates, parties and independent organizations in 2020. In 2022, a total of $2.1 million was spent on one Senate election and $1.58 million on another.
Expect 2024 spending on some Senate races to blow past those numbers.
