Here you DougR, a history of the Pew Charitable Trusts:

The Pew Charitable Trusts serve the public interest by providing information, policy solutions and support for civic life. Based in Philadelphia, with an office in Washington, D.C., the Trusts make investments to provide organizations and citizens with fact-based research and practical solutions for challenging issues. In 2003, with approximately $4.1 billion in dedicated assets, the Trusts committed more than $143 million to 151 nonprofit organizations.

History
The Trusts, an independent nonprofit, are the sole beneficiary of seven individual charitable funds established between 1948 and 1979 by two sons and two daughters of Sun Oil Company founder Joseph N. Pew and his wife, Mary Anderson Pew.

To suggest that the Pew Trust is Democratic is like saying the Ford Foundation or the Rockefeller Foundation is Democratic.

Maybe you don't understand the difference between a foundation and a think tank, there DougR. They aren't interchangeable, you know.

Was it Faux News whispering in your ear again DougR, telling you that Pew polls were flaming radical left wing communist propaganda?
