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. , 
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.” 
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.  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.” 
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.” , 
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.” , 
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. , 
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. 
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. 
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.  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. 
“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):
“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. , 
“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. 
“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.” 
Mackinac Center & The American Legislative Exchange Council (ALEC)
“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.”

The Mackinac Center for Public Policy, represented by Jason Hayes, was among 22 groups represented in a “Coalition” open letter pushing back against what the Heartland Institute describes as an “affront to free speech.” The groups are responding to the recent Web of Denial Resolution brought up in the Senate, calling out fossil fuel industry-funded groups denying climate change. 
According to the Climate Investigations Center, all but one of the open letter's signatory organizations have taken money (totalling at least $92 million since 1997) from the “climate denial web” including Koch Brothers' various foundations, ExxonMobil, and two “Dark Money” organizations, Donors Trust and Donors Capital Fund. 
Championed by Senators Whitehouse, Markey, Schatz, Boxer, Merkley, Warren, Sanders, and Franken, the resolution condemns what they are calling the #WebOfDenial — “interconnected groups – funded by the Koch brothers, major fossil fuel companies like ExxonMobil and Peabody Coal, identity-scrubbing groups like Donors Trust and Donors Capital, and their allies – developed and executed a massive campaign to deceive the public about climate change to halt climate action and protect their bottom lines.” 
The open letter addresses the senators, calling them “tyrants”:
“We hear you. Your threat is clear: There is a heavy and inconvenient cost to disagreeing with you. Calls for debate will be met with political retribution. That’s called tyranny. And, we reject it.” 
The full list of signatories and their respective organizations is as follows:
- Grover Norquist — Americans for Tax Reform
- Lisa B. Nelson — American Legislative Exchange Council
- John A. Charles, Jr. — Cascade Policy Institute
- David Rothbard — Committee for a Constructive Tomorrow
- Kent Lassman — Competitive Enterprise Institute
- Nicole Neily — Franklin Center for Government and Policy Integrity
- Benita Dodd — Georgia Public Policy Foundation
- Bridgett Wagner — The Heritage Foundation
- Fred Birnbaum — Idaho Freedom Foundation

- Brett Healy — The John K. MacIver Institute for Public Policy

- Sally Pipes — Pacific Research Institute
- Kevin Kane — Pelican Institute for Public Policy
- Paul J. Gessing — Rio Grande Foundation
- Lynn Taylor — Virginia Institute for Public Policy
- Carol Platt Liebau — Yankee Institute for Public Policy
Writing in Michigan Capitol Confidential (one of the Mackinac Center's “daily news” sites),  Tom Gantert writes that the recent efforts by a coalition of state attorneys general to investigate ExxonMobil's knowledge of climate change. 
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.” 
“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.
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.”
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.”
