Fall: Oath • Spending
This is a group created in 2003 by David and Charles Koch, the billionaire owners of Koch Industries and Wisconsin-based papermaker Georgia-Pacific. Americans for Prosperity first got involved in Wisconsin state politics through the medium of "issue ads" in 2006 and first reporting independent expenditures in 2018. It operates as an unregistered indpendent expenditure committee, meaning it is not legally obligated to report its sources of income to the state. It only has to report independent expenditures made 60 days before a primary or general election and does not have to report any spending made outside that interval. Between 2010 and 2024 the group spent over $25.3 million on issue ads and independent expenditures combined to influence Wisconsin state elections.
The group first reported spending in the 2026 fall gubernatorial election, in mid June with over $450,000 spent on dgital adverting, canvassing and doorhanger production in support of Republican U.S. Congressman Tom Tiffany's bid to replace retiring Democratic Governor Tony Evers. A few days later it reported spending over another $150,000 for more of the the same.
The first Friday in July, Americans for Prosperity reported spending over another $600,000 for canvassing and digital ads in support of Tiffany.
A member the far-right House Freedom Caucus, Tiffany enjoys the endorsement of the President Donald Trump and faces only token oppostion in the August 11th Republican primary from political newcomer Andy Manske. Meanwhile, seven Democrats were originally vying for their party's nomination, although two of them suspended their campaigns by mid-July.
Towards the end of the second week in July, Americans for Prosperity reported spending another $8,400 for digital ad production to support Tiffany. It also reported splitting about another $100,000 for canvassing and campaign literature to support Republicans in two state senate races, incumbent Sen. Howard Marklein of the 17th State Senate in south-west Wisconsin and Mike Roberts in suburban Milwaukee’s 5th Senate. Political observers consider Marklein’s district to be more Democratic after the passage of new district maps in 2024. Roberts faces Democrat State Rep. Robyn Vining for the open suburban Milwaukee seat, currently held by GOP Sen. Rob Hutton. The 5th Senate is also regarded as leaning more Democratic now.
A day later, the second Friday in July, the group reported spending over another $300,000 on digital ads, campaign literature and canvassing to support Republicans in two more state senate races, the 11th and the 31st, and four in the assembly, the 30th, 61st, 88th and the 92nd. The four assembly districts are currently held by Republicans, all of whom face Democratic challengers. The 11th Senate is an open seat where long-time incumbent Sen. Steve Nass is retiring. In that race, Americans for Prosperity supports former state Rep. Ellen Schutt in a three-way primary. The winner of that primary faces Democratic opposition in November. The 31st State Senate is currently held by a Democrat, Sen. Jeff Smith, who won his last election in 2022 by less than one percentage point. His Republican opponent, Michele Skinner, who ran for the state assembly in 2024, is unopposed in the primary.
The second Monday in July, Americans for Prosperity reported spending $41,000 more for digital ad production and placement in the four state assembly races mentioned in the preceding paragraph. A few days later it reported spending $1,800 for digital ad production in support of Tiffany.
The third Monday, in July, about three weeks out from the August primary, the committee reported spending nearly $49,000 for doorhanger production, canvassing and digital ad production across seven races, the governor, five in the senate and two in the assembly. Two of the contests are new to independent spending this year, the 21st Senate and the 89th Assembly. The former race is an open seat long held by GOP Sen. Van Wanggaard while the latter features a first-term Democratic incumbent. There is no primary in either district.
About three weeks out from the primaries, it reported spending another $2,500 for digital ad production to support Schutt.
The last Sunday in July, it reported spending a further $58,000 for digital ads supporting Republicans in the 21st Senate and the 89th Assembly.
Eight days before the primaries, it reported spending $700,000 for digital ads supporting Tiffany for governor. The next day, with just a week to go, it reported spending over $22,500 on canvassing and doorhangers in four state senate races- the 5th, 17th, 21st and the 31st - and five in the state assembly, the 30th, 61st, 88th, 89th and the 92nd. The committee had already reported spending in all those races earlier.
Last active election: 2025
