The Heartland Institute, according to the Institute's web site, is a nonprofit "think tank" that questions the reality and import of climate change, second-hand smoke health hazards, and a host of other issues that might seem to require government regulation. Heartland Institute is an "associate member" of the State Policy Network, a web of right-wing “think tanks” and tax-exempt organizations in 49 states, Puerto Rico, Washington, D.C., Canada, and the United Kingdom.
