Who pays for Wisconsin elections? How the rules move millions
ANALYSIS -- In Wisconsin, there's no limit on how much money individuals can donate to political parties or how much those parties can contribute to candidates. But individuals can give no more than $20,000 directly to a candidate for governor.
In the 2026 governor's race, both Republicans and Democrats have moved millions of dollars into their candidates' campaigns.
Between July 28 and September 23, the Republican Party of Wisconsin contributed approximately $24.4 million in monetary and in-kind support to Tom Tiffany's campaign. That accounted for roughly 92 percent of the $26.3 million his campaign reported receiving.
Democrat David Crowley's campaign reported approximately $10.5 million in receipts through September 23. Nearly $3 million came from the Democratic Party of Wisconsin, accounting for about 28 percent of his campaign's receipts.
Wisconsin didn't always finance elections under these rules. The state once provided public funding to candidates who agreed to limit their campaign spending.
When Wisconsin helped pay for political campaigns
Wisconsin lawmakers passed a major overhaul of the state's campaign finance laws in 1973. The changes took effect in 1974, establishing limits on political contributions and stronger requirements for reporting campaign finances.
Three years later, Wisconsin established the Wisconsin Election Campaign Fund, offering public funding to qualifying candidates for governor, other statewide offices and the state Legislature.
Candidates who accepted the money agreed to limits on their campaign spending. The arrangement was voluntary, following a 1976 U.S. Supreme Court ruling that prohibited mandatory campaign spending limits but allowed candidates to accept them in exchange for public financing.
The program was funded largely through an income tax checkoff. Taxpayers could direct $1 of the state income taxes they already owed to the fund, an amount later increased to $3. Checking the box didn't increase their taxes or reduce their refunds.
Wisconsin expanded public financing in 2009 with the Impartial Justice Act, which established a separate program for state Supreme Court elections. Qualifying candidates received public grants in exchange for restrictions on fundraising and spending.
Both programs ended in 2011, when the Republican-controlled Legislature eliminated them through the state budget signed by Republican Gov. Scott Walker.
How Wisconsin changed its contribution limits
In 2014, the U.S. Supreme Court struck down federal limits on how much an individual could contribute in total to candidates and political committees. The ruling did not eliminate limits on donations to individual candidates.
Wisconsin had a similar $10,000 annual limit on total political contributions. Following the Supreme Court ruling, a federal court blocked Wisconsin from enforcing that limit.
In 2015, Republican Gov. Scott Walker signed Wisconsin Act 117, which doubled the amount individuals could contribute directly to state candidates. The limit for gubernatorial candidates increased from $10,000 to $20,000. State Senate candidates could receive up to $2,000 from an individual, while the limit for Assembly candidates increased to $1,000.
The law also removed limits on how much individuals could give to political parties and how much those parties could contribute to candidates. Neither court ruling required those changes.
Political parties decide how to distribute the money they receive. Individual donors cannot earmark their contributions for transfer to a particular candidate.
Nick Ramos, executive director of the Wisconsin Democracy Campaign, questioned the effect of those changes.
“What's the point of having contribution limits if somebody can simply route their money through the political party?” Ramos said.
Following the money through Wisconsin elections
During the summer and fall of 2010, contributions from state political parties accounted for less than 2 percent of the campaign receipts reported by Scott Walker and Democrat Tom Barrett. Walker received approximately $69,000 in party support, compared with about $34,000 for Barrett.
By 2014, the Republican Party had provided Walker with approximately $1.17 million in monetary and in-kind contributions, accounting for about 10 percent of his campaign's receipts. The Democratic Party contributed $200,000 to Mary Burke, or roughly 2 percent of hers.
Between July 1 and October 24, 2022, the Democratic Party provided approximately $6.85 million in monetary and in-kind support to Tony Evers, accounting for 39 percent of his campaign's receipts. The Republican Party contributed approximately $3.29 million to Tim Michels, or about 19 percent.
By 2026, political parties accounted for an even larger share of the money going into gubernatorial campaigns. Their contributions made up approximately 28 percent of David Crowley's reported receipts and 92 percent of Tom Tiffany's during the periods examined.
Large individual contributions have also flowed into the political parties. Between July 28 and September 23, Richard and Elizabeth Uihlein contributed a combined $22 million to the Republican Party of Wisconsin, while Diane Hendricks contributed approximately $5.6 million.
The Democratic Party of Wisconsin also received substantial contributions during that period. Illinois Gov. J.B. Pritzker and Lynde Uihlein each contributed $1 million, while Lynn Schusterman contributed $990,000. The party also received approximately $565,000 from Democratic Gov. Tony Evers' campaign fund.
Wisconsin's campaign finance records list donations to political parties separately from the money those parties give to candidates. The records don't show whether contributions from any particular donor ultimately reached Crowley or Tiffany.
These figures cover different reporting periods rather than entire election cycles, and they don't establish how much of the increase resulted from Wisconsin's 2015 law. They do show that political parties now account for a much larger share of the money reported by gubernatorial campaigns.
The money spent outside campaigns
In 2010, candidates and outside groups spent a combined $37.37 million on Wisconsin's governor's race, according to the Wisconsin Democracy Campaign. By 2022, that figure had reached $164.29 million.
Outside groups spent approximately $12.1 million in the 2010 race. Twelve years later, they spent an estimated $85.94 million — roughly seven times as much.
Unlike the earlier party contribution figures, these totals cover the full election cycles.
Outside groups spend money to support or oppose candidates without giving it directly to their campaigns. That spending doesn't appear in the candidates' campaign finance receipts.
The U.S. Supreme Court's 2010 ruling in Citizens United v. Federal Election Commission allowed corporations and labor unions to spend unlimited amounts independently to influence elections. Other court rulings cleared the way for super PACs to raise and spend unlimited amounts independently of candidates. Limits on direct contributions to candidates remained in place.
Independent expenditures cannot be coordinated with candidates or their campaigns. Wisconsin law, however, treats certain other political advertising differently.
Elizabeth Shimek, managing legal counsel for campaign finance at the Campaign Legal Center, said Wisconsin's 2015 changes made it easier for political parties and outside organizations to coordinate with candidates.
“They made a lot of different changes to Wisconsin's campaign finance laws that made it much easier for parties to raise money to coordinate with candidates, and for outside spenders to communicate and coordinate with candidates and political parties,” Shimek said.
Wisconsin law distinguishes between advertising that explicitly calls for a candidate's election or defeat and advertising focused on public policy issues.
Outside groups generally cannot coordinate advertising that expressly supports or opposes a candidate with that candidate's campaign without triggering campaign finance restrictions. Such spending can be treated as a campaign contribution and become subject to contribution limits.
Wisconsin law allows certain issue-focused advertising to be coordinated without counting it as a campaign contribution.
The Supreme Court's Citizens United decision also upheld disclosure requirements for certain political spending.
“And what they agreed on is that while these spenders can spend unlimited money, voters have a corresponding right to know who is spending,” Shimek said.
But not every outside organization is required to publicly identify all its donors. Disclosure requirements depend on the type of organization and its political activities.
Voters may be able to identify who paid for an advertisement without knowing who supplied the money.
How campaign money reaches local elections
Wisconsin's campaign finance laws also apply to local elections, including school board and city council races, although limits on direct contributions are generally lower.
Individuals can contribute up to $500 directly to candidates in districts with 25,000 residents or fewer. In larger districts, the limit is based on population and can reach $6,000. Political action committees, or PACs, have separate contribution limits. Outside groups can spend unlimited amounts independently to support or oppose candidates.
Local candidates generally file campaign finance reports with local clerks, while the Wisconsin Ethics Commission maintains records of independent spending by political organizations.
During Wisconsin's 2026 spring election, WEAC Region 7 PAC, affiliated with the state's teachers' union, reported $400 contributions to three school board campaigns. The recipients were Friends of Kathleen Wied-Vincent, Morales for Muskego-Norway Schools and Friends of Connie Kincaide.
All three contributions were made March 9, according to the committee's pre-election report.
The 1776 Project PAC, a national conservative political action committee that supports school board candidates, reported approximately $321,300 in independent expenditures supporting candidates in Wisconsin's 2026 spring election, according to three reports filed with the Wisconsin Ethics Commission.
The expenditures included canvassing, advertising and text messaging in districts including Waukesha, Elmbrook, Germantown, New Berlin, Sun Prairie and Winneconne.
The records identify two companies receiving the payments: Logan Circle Group, a conservative political consulting firm specializing in advertising and communications, and Mobilize the Message LLC, which focuses on voter outreach and door-to-door canvassing.
Those three reports may not account for everything the organization spent during the election.
During the 2024 spring election, the Wisconsin Conservation Voters Independent Expenditure Committee reported approximately $55,800 in independent expenditures associated with seven Green Bay City Council candidates. State records show the money went toward campaign mailings, graphic design and online advertising.
How other states handle campaign financing
Maine voters approved the state's Clean Election Act in 1996, creating a public financing program for political candidates. In the 2026 election, candidates for governor must collect at least 3,200 contributions of $5 or more from registered voters to participate. State Senate candidates need 175, while state House candidates need 60.
Candidates who meet those requirements receive public money for their campaigns and can receive additional funding by collecting more small contributions. Once enrolled, they generally cannot accept private campaign donations.
Arizona has a similar public financing program that requires candidates to collect $5 contributions from eligible voters.
In 2022, Arizona voters also approved Proposition 211, requiring certain organizations that pay for political advertising to disclose where large contributions originally came from, even when the money passes through other groups.
The law generally applies to organizations spending more than $50,000 on statewide campaign advertising or $25,000 on other elections. Donors who contribute more than $5,000 toward that spending must be identified in public reports. The requirements help voters see who originally supplied the money, not just which organization paid for the advertising.
“So it's not just group A funded by group B. They're going to look all the way back and they're going to figure out who actually earned large contributions that are going into it,” Shimek said.
On June 29, 2026, the Arizona Supreme Court rejected challenges to the law's overall constitutionality under the state constitution but allowed a narrower challenge to proceed.
Efforts to change Wisconsin's campaign finance laws
Democratic lawmakers have repeatedly proposed restoring contribution limits since Wisconsin changed its campaign finance laws in 2015. Bills introduced in 2019, 2021 and 2023 sought to restrict donations to political parties, transfers to candidates and direct contributions. None passed.
The latest proposals, Assembly Bill 1219 and Senate Bill 1153, were introduced in March 2026. They would have reduced the individual contribution limit for gubernatorial candidates from $20,000 to $10,000.
The bills also would have restored limits on donations to political parties, capped party contributions to gubernatorial candidates at $10,000 and reduced limits on PAC contributions to candidates.
Both bills were introduced March 19 and referred to legislative committees. Neither received a floor vote before the legislative session ended March 23.
Federal court rulings protect unlimited independent political spending, but Wisconsin lawmakers can still change certain contribution limits and disclosure requirements.
“We could just add contribution limits onto donations to political parties,” Shimek said.
She also said Wisconsin could restore public financing for state elections and require greater disclosure of who funds political advertisements.
Nick Ramos, executive director of the Wisconsin Democracy Campaign, said his organization and others plan to pursue additional disclosure requirements in 2027 and beyond to help voters identify the original sources of money behind political advertising.
Asked how Wisconsin elections might change with stronger campaign finance restrictions, Ramos pointed to the amount of money involved.
“It would look radically different,” he said. “We'd be talking about still millions of dollars, but we would not be playing chicken with a hundred million dollar price tag.”
