Mackinac Center for Public Policy

Mackinac Center for Public Policy


The Mackinac Center for Public Policy is a nonprofit, tax-exempt organization under Section 501(c)(3) of the IRS. Originally named the Michigan Research Institute, the organization was founded in 1987 as a state-level conservative policy think tank in Michigan. [1], [2]

The Mackinac Center describes itself as a “nonpartisan research and educational institute dedicated to improving the quality of life for all Michigan citizens by promoting sound solutions to state and local policy questions.” [3]

Mother Jones reports that the Mackinac Center has been known as a vocal opponent of unions in Michigan, while receiving a large portion of their initial funding from the DeVos family. [34] Dick Devos has also served on the Center's Board of Directors. Mother Jones has also described the Mackinac Center's close ties to the Republican Party“The Mackinac Center has been tied at the hip with the Republican Party establishment for years,” Doug Pratt, public affairs director at the Michigan Education Association told Mother Jones. “It goes to their funding sources; it goes to their ideology.” [35]

The Mackinac Center was created with seed money from the Cornerstone Foundation, as well as $335,986 from various officials of Dow Corning and Dow Chemical. Their second-largest donor is Donors Capital Fund (DCF), which contributed at least $3,203,500 to the Mackinac Center between 1993 and 2013. Donors Capital Fund and its sister organization, DonorsTrust have been described as the “dark money ATM of the conservative movement in the US.” They allow for anonymous donations, mostly from conservative individuals and foundations, to flow to organizations while hiding their identity through “donor advised funds.” [4], [5]

The Mackinac Center's publications include MichiganScience and The MC (Mackinac Center Blog).

Academics have criticized the Center, saying that “Mackinac Center research is often of low quality and because of this it should be treated with considerable skepticism by the public, policy makers and political leaders. Much of the work of the Mackinac Center may have caused more confusion than clarity in the public discussion of the issues that it has addressed by systematically ignoring evidence that does not agree with its proposed solutions.” [6][4]

Mackinac Center & Climate Change Denial

The Mackinac Center regularly publishes articles questioning man-made climate change. The Center has questioned prominent climate policy consultants, and have historically cited the work of skeptical individuals and organizations such as the Cato Institute[20][21]

The Mackinac Center's publication “MichiganScience” has covered the “Climategate” issue more than once. Henry Payne writes in Climategate reveals that some scientists have tilted decidedly toward dishonesty, vilifying their critics and manipulating data to “trick” the public and “hide the decline” in global temperatures. [22]

In 2001, researchers Peter Cookson, Jr. Ph.D. and Katie Embree Ph.D. of Columbia University, and Alex Molnar, Ph.D. of Arizona State University, reviewed the Mackinac Center’s research on education issues. They found that the Mackinac Center's “reports tend to use social science language without proper social science methods in a way that gives the appearance of social scientific legitimacy to the Center‟s preconceived beliefs and ideas.” [4]
The study went on to say that “Center reports tend to use social science language without proper social science methods in a way that gives the appearance of social scientific legitimacy to the Center’s preconceived beliefs and ideas.”

Mackinac Center's Nonprofit Status Questioned

Citizens advocacy group Progress Michigan released audio from an Americans for Prosperity “Citizen Watchdog Training” event which they claim shows the Mackinac Center has been involved in lobbying for Right to Work (RTW) laws in Legislature. [39]

According to a Progress Michigan press release, F. Vincent Vernuccio, the Mackinac Center’s Director of Labor Policy, “admitted to meeting with lawmakers to make a plan for ramming RTW laws through the Legislature.”

Lansing politicians have spent the last two years ramming through a right-wing wish list of attacks on middle class families through tax increases and cuts to education,” said Zack Pohl, Executive Director of Progress Michigan. “It’s clear that despite calling itself a non-partisan think tank, the Mackinac Center has been intimately involved in lobbying Republicans to get their legislative agenda passed – and the worst part is, they’re doing it without even a minimal amount of transparency or disclosure.”

While the Mackinac Center does not admit to lobbying to the federal Internal Revenue Service or the state of Michigan, emails obtained by Progress Michigan in 2011 indicated that “the Mackinac Center was actively seeking to influence the legislative process on a series of bills related to health care benefits for teachers and other public workers.” 

In 2012, Congressman Sander Levin sent the IRS a letter asking them to investigate the tax-exempt status of the Mackinac Center after the emails were found indicating “a long-term plan to lobby.”

Progress Michican released a report on the Mackinac Center that further called the Center's “nonpartisan” and nonprofit status into question. [37] According to the report, the Mackinac center had made at least wo payments payments categorized in official records as political contributions, one to the Michigan Republican Party and another to the Livingston County Republi-can Committee. [38]

“Both contributions are apparent violations of the Mackinac Center’s 501(c)(3) nonprofit status,” the report reads. “Moreover, an analysis of campaign contributions made by Mackinac Center board members shows an overwhelming majority going to GOP candidates.”

Stance on Climate Change

Note: while the Mackinac Center for Public Policy does not appear to have an official statement on cliamate change, many of its staff members do present their own views on the topic (often in the Center's own publications):

December, 2015

“The claim that 97 percent of climatologists (or climate scientists) agree that global warming poses a significant threat and is being primarily driven by human activities has become the centerpiece of the man-made global warming argument. This, more than all other aspects of the issue, is the big lie that must be challenged” — Jack Spencer, past Capital Affairs Specialist, Mackinac Center. [28], [29]

January, 2015

“One of the most widely believed urban myths of our time is that the oil (aka fossil fuel) industry wants to and works to undermine the belief in man-made climate change.” — Jack Spencer, Mackinac Center blog. [30]

October, 2014

“The alarmists screech and holler, but when their assertions and predictions are debunked, they are consistently allowed to move on to the next temporary circumstance they seek to exploit. It’s high time that they suffer the loss of credibility they deserve. News media and politicians have a responsibility to stand up and take notice when the claims of global warming alarmists are revealed to have been hogwash. Our society in general has a right to be told the true score.” Jack Spencer, Mackinac Center blog. [27]

March, 2010

“The rush to declare scientific proof of green doctrine and secure related research funds has led to a false cry of consensus.” — MichiganScience [7]

February, 2010

Daniel Hager, Mackinac Center Adjust Scholar, describes mainstream climate science as one of the “pseudosciences”, citing well-known climate change deniers Patrick J. Michaels and Robert C. Balling Jr.:
“Manipulation of statistics through selective use of base points is a treasured tactic in the pseudosciences. Climatologists Patrick J. Michaels and Robert C. Balling Jr., in their 2000 book “The Satanic Gases,” offer an example that would be amusing if it were not so chilling.” [36]

Mackinac Center & The American Legislative Exchange Council (ALEC)

The following is reproduced from a November 2013 report by Progress Michigan: [37]

“The Mackinac Center is an active member of the American Legislative Exchange Council (ALEC), a corporate bill mill. Over the years, Mackinac staffers have proposed numerous bills at ALEC task force meetings, where elected officials and private sector members (like corporate lobbyists and special interest groups) vote as equals behind closed doors on tem-plates to change the law. Under ALEC’s public bylaws, its state legislative leaders are tasked with a 'duty' to get those bill introduced into law. The coordinated agenda that ALEC and the Mackinac Center advocate for includes:

  • Attacking workers' rights with the recent so-called 'Right to Work' law, pushing paycheck deception measures, calling for the repeal of the pre-vailing wage law and advocating for bills that cut public pension benefits
  • Blocking the bipartisan effort in Michigan to expand Medicaid and imple-ment the Affordable Care Act that would give access to affordable health-care to millions of Michigan residents
  • Defunding and privatizing Michigan's public schools with voucher pro-grams and charter schools
  • Denying the science behind climate change and global warming, while also opposing the use of clean and renewable energy sources”


According to their website, the Mackinac Center “enjoys the support of foundations, individuals, and businesses who share a concern for Michigan's future and recognize the important role of sound ideas.” [3]

May, 2016

Writing in Michigan Capitol Confidential (one of the Mackinac Center's “daily news” sites), [33] Tom Gantert writes that the recent efforts by a coalition of state attorneys general to investigate ExxonMobil's knowledge of climate change. [31]

Gantert repeats the same “freedom of speech” argument used by ExxonMobil's own lawyer, as well as the recently-created Free Speech in Science Project. He argues that the attorneys general are trying to “silence opponents of progressive theories” with the “threat of criminal prosecution.” [32]

“While these nonprofits and climate change dissenters are the current targets, one attorney warns the tactic represents a danger to political free speech that is protected by the First Amendment,” Gantert writes. 

June, 2011

The Mackinac Center appears to be pro-Hydraulic Fracturing in the state of Michigan, based on an article published in its MichiganScience magazine. [23]

Although the author admits that “The development of gas wells using hydraulic fracturing technology poses some environmental risk,” the article suggests that “state officials should resist the temptation to over-regulate the [fracking] process, which could result in the loss of valuable jobs and an additional source of energy to heat Michigan’s homes and power its factories.”

See DeSmogBlog's own report on the environmental impacts of Fracking.

May 21, 2011

The Mackinac Center published a blog post on their website rhetorically asking readers if “90 percent of scientists really buy into global warming alarmism.”

Citing William Happer and John Christy as part of the “remaining 10 percent” that do not “buy into global warming alarmism,” the Mackinac Center's blog post quoted Happer as saying “It is fashionable to believe in harmful global warming due to evil mankind … What could be a more worthy cause than saving the planet?” and Christy as saying “The problem is the degree of warming … Ninety percent would agree that mankind has some impact on the climate, but a lower percentage would say it was a dangerous impact.” [24]

March 17, 2010
The Mackinac Center convened a climate change panel titled “The Changing Debate on Climategate” moderated by Mackinac's senior environmental-policy analyst Russ Harding. The panel also included Henry Payne, Shikha Dalmia of the Reason Foundation, and Paul Chesser of the Heartland Institute. [25], [26]
