Two high-profile candidates for governor of Wisconsin, Republican U.S. Rep. Tom Tiffany and Democratic former Lt. Gov. Mandela Barnes, have denounced the unlimited flow of cash into state political campaigns. Then, practically in the same breath, both men announced their plans to raise tens of millions of dollars, signalling to their less well funded primary opponents that they might as well get out of the way.

In an interview with PBS Wisconsin on Dec. 5, Tiffany criticized “that pass-through loophole, I call it the ‘billionaire loophole,’” in Wisconsin law, adding, “there’s just so much money that comes into Wisconsin.” 

“You can cry about it or you can compete,” Tiffany continued. “We choose to compete … We’re hoping to raise $40 million.”

As Baylor Spears reports, Tiffany actually voted for the “billionaire loophole” he now criticizes back when he was serving in the state Senate in 2015. 

Mandela Barnes, in a recent campaign stop in Madison, told Spears and other reporters that he has raised a “strong haul,” in the first week of his campaign, and that he intends to raise a staggering $50 million by the end of the race. He added that he doesn’t like the role of money in politics. “It’s not a good sign,” he said, and his future goal is “to get big money out of politics” and enact “campaign and ethics reform.”

Back in 2015, when Republicans were ramming through the “billionaire loophole,” Barnes opposed it, saying at the time that it would allow “shady special interest money and allow for more corruption to go undetected and unprosecuted.”

Jay Heck, executive director of Common Cause Wisconsin, remembers that moment well. Under former Republican Gov. Scott Walker, Republican legislative majorities passed the law eviscerating campaign finance limits along with other measures getting rid of the nonpartisan Government Accountability Board and eliminating the John Doe procedure that was used to criminally prosecute leaders of both political parties for campaign finance crimes in the infamous caucus scandal of the early 2000’s.

The 2015 law doubled the amount individuals could give to candidates. More importantly, it eliminated all limits on state party contributions to candidates and allowed coordination between candidates and outside groups that make issue ads supporting the campaigns. Donors were able to give as much as they wanted to political parties, which then funneled that money to candidates, creating the billionaire loophole to which Tiffany belatedly objects. The 2015 law cleared the way for outsiders like Elon Musk to pour limitless cash into state races to try to affect the outcome.

“The Republicans did that in 2015 because they were convinced that they would have a great financial advantage since they generally raised more money from donors and special interests,” says Heck. “Of course, what they didn’t anticipate was [former Wisconsin Democratic Party chair] Ben Wikler and the Democratic Party’s ability to take that big hole in the law and use it to raise massive amounts of money.”

Recently, Democrats in Wisconsin have been beating Republicans in the fundraising arms race. In 2025, in the most expensive judicial election in U.S. history, Susan Crawford, the candidate for the Wisconsin Supreme Court supported by the Democratic Party, raised $28.3 million compared with Republican-supported Brad Schimel, who raised $15.1 million. Outside special interests accounted for most of the spending on the race, with Musk alone putting in nearly $20 million through his political action committees and millions more laundered through the state Republican Party for Schimel, while the Democratic Party of Wisconsin funneled $10 million to Crawford.

The lesson of the 2015 law, says Heck, is, “be careful what you wish for.”

That certainly applies to Republicans, who lost the two most expensive state Supreme Court races in history as well as the last two record-breaking gubernatorial races won by Gov. Tony Evers with $93 million in total spending in 2018 and $164 million in 2022. 

But it also applies to Democrats, who cannot count on continually bringing in more money than Republicans.

More importantly, when it costs tens of millions of dollars to win state elections, regular voters’ voices are drowned out by billionaires, who are not investing in candidates just out of the goodness of their hearts.

Heck believes that change will only come when voters demand reform, most likely because a big scandal clearly illustrates that politicians are doing favors for their donors in exchange for campaign cash.

“It’s going to require a bipartisan coming-together to establish some limits,” Heck says. 

Even as the U.S. Supreme Court has opened the floodgate for campaign spending with the Citizens United decision, which in 2010 struck down a federal ban on political donations from corporations, and McCutcheon v. FEC, which in 2014 found that annual caps on total political donations from one person are unconstitutional, states have the ability to impose limits. 

A report by the National Conference of State Legislatures shows Wisconsin is one of only 11 states that allow unlimited candidate contributions by state parties and among the top 10 for the highest limits on PAC contributions to candidates. Minnesota, Michigan, Illinois and most other states limit how much political parties can accept, which reduces the Elon Musk effect. Plus, “We are one of few states that allows so-called coordination between political candidates and outside groups,” Heck says.

The problem is that candidates, while acknowledging that massive amounts of money fueling their campaigns is a bad look, don’t want to unilaterally disarm. 

But now, as the Trump administration drags the country to new levels of overt corruption, it could be a good time for a campaign that ties together billionaires’ destructive influence on society and the fact that they are buying our democracy. 

“There has to be public disgust with the amount of money being spent,” says Heck. “If a candidate put corruption front and center, it might get a lot of traction.”

“Costs, like everything else, are out of control, and coming from a family that had to make every dollar count, I know what that feels like,” Joel Brennan said in his launch video. (Screenshot from campaign video)

Joel Brennan, formerly the Department of Administration (DOA) secretary under Gov. Tony Evers, announced his campaign for governor Thursday, saying that President Donald Trump’s “chaos and incompetence” are hurting the state and that “the numbers just aren’t adding up for Wisconsin families.”

“Costs, like everything else, are out of control, and coming from a family that had to make every dollar count, I know what that feels like,” Brennan said in his launch video. “I’ll be a governor who will stand up to Trump’s dysfunction and be laser focused on improving the lives of people across our state.”

In the video, Brennan introduces himself, saying many voters “probably don’t know much about me.” He talks about growing up as one of 11 children in a family that was “long on potential, although sometimes a little short on resources.” He relates that he worked in many jobs including landscaping, retail and deep frying egg rolls to help put himself through college and that his first car had no working blinkers.

“I’ve raised two great kids with my wife, Audra, passing on lessons like rolling up our sleeves to get things done and showing up for our community, and for 25 years I’ve worked with businesses and non-profits to create jobs and strengthen Wisconsin’s economy.”

Brennan served as the DOA secretary from 2019 through 2021. The agency is responsible for assisting the governor with the state budget, providing centralized purchasing and financial management for state agencies and working with the 11 federally recognized Native Nations in Wisconsin on gaming and coastal programs. 

“It’s easy to forget how broken things were after [former Gov.] Scott Walker and his right-wing Legislature had spent eight years gutting state government,” Brennan said. “We got to work putting the state on firmer financial footing, generating a budget surplus of nearly $4 billion dollars and growing our rainy day fund to $1.7 billion, then COVID hit and all of that progress was put at risk. We stood up to the extremists and delivered help to tens of thousands of small businesses, farmers, and families across Wisconsin.”

Prior to his time in Evers’ administration, Brennan worked as the executive director of Discovery World, the largest science museum in Wisconsin. 

Brennan stepped down from leading the DOA in December 2021 to serve as the president of the Greater Milwaukee Committee (GMC). The private-sector, nonprofit civic organization works to foster economic development and cultural growth in Wisconsin’s largest metro area.

According to the Greater Milwaukee Committee, Brennan is stepping aside from the role as he runs for governor. 

Brennan joins a crowded field of hopefuls seeking the Democratic nomination next year. Candidates include Lt. Gov. Sara Rodriguez, state Sen. Kelda Roys (D-Madison), state Rep. Francesca Hong (D-Madison), Milwaukee County Exec. David Crowley, former Wisconsin Economic Development Corporation CEO Missy Hughes, former Lt. Gov. Mandela Barnes and former state Rep. Brett Hulsey. The primary is scheduled for Aug. 11, 2026.

Roys criticized Brennan in a statement after his announcement over a position the GMC took on a Milwaukee Public Schools referendum last year, saying that Wisconsin needs “a leader who knows how to deliver higher wages, lower costs and the freedom to thrive.”

“While I look forward to a spirited primary, I will not be able to overlook the fact that only one of the candidates in this race tried to defeat a desperately needed referendum to fund our biggest school district,” Roys said. 

The GMC, under Brennan’s leadership, was one of the city’s business organizations that opposed the $252 million operational referendum successfully sought by Milwaukee Public Schools in 2024. GMC expressed concerns at the time over transparency and the “failure to clearly articulate a measurable plan for how these additional financial resources will improve student outcomes.”

The Republican field for governor is not as expansive with just two candidates: U.S. Rep. Tom Tiffany, the frontrunner in the race, and Washington Co. Executive Josh Schoemann.
