GOP donors give big to party after state campaign finance changes

Mike and Mary Sue Shannon each gave the maximum contribution to Gov. Scott Walker's campaign in June 2017.

The same day Walker's campaign reported the $20,000 donations from the Denver couple — both are UW-Madison graduates, and Mike Shannon went on to found a multibillion-dollar private equity firm — the state GOP registered $125,000 donations from each of them. Those donations wouldn't have been allowed under previous Wisconsin campaign finance laws that were first struck down by the courts and then affirmed by a GOP overhaul of the regulations.

The Denver couple wasn't alone in taking advantage of the change.

A check of donations found 29 donors since Jan. 1, 2015, who contributed a combined $3.3 million to the state GOP after maxing out to Walker. All but three of those contributions were at least $10,000, and more than half of the $3.3 million came from just three donors: Beloit businesswoman Diane Hendricks and Illinois business couple Dick and Elizabeth Uihlein.

Wisconsin didn't previously cap contributions to state parties. But an old restriction limiting donors to an aggregate of $10,000 in contributions to campaigns and committees per year acted as a de facto cap. That annual aggregate limit was thrown out by a federal court in September 2014; and when GOP lawmakers overhauled campaign finance laws a little more than a year later, they didn't include any restrictions on the size of donations to political parties.

Matt Rothschild of the Wisconsin Democracy Campaign, which lobbied against the GOP campaign finance bill, said including a cap on donations to political parties of $10,000 would have reflected the intent of the old law.

The GOP package also doesn't restrict how much parties or legislative campaigns can transfer to candidates, meaning the Republican Party could funnel those six-figure donations to Walker.

Since Jan. 1, 2015, the party has given the governor $74,664, with the largest donation $10,000.

Hendricks, who has become a major donor in Wisconsin politics, maxed out to Walker for the cycle in June 2017 then sent donations of $500,000 to the state GOP later that month and again in April. Before hitting the $20,000 mark to Walker, she gave the party $700,000, pushing her overall contributions to the state GOP to $1.7 million since Jan. 1, 2015.
