Think Progress has a breathless post up today alleging they have uncovered the Koch brothers sinister plot to coordinate corporate, libertarian, and conservative donors to outside groups and think tanks. What they’ve actually uncovered is (horrors) an invitation-only conference of generally like-minded philanthropic and other organizations that likes to discuss issues and strategies and hear from prominent thinkers and commentators (including, on at least one occasion, NRO’s Ramesh Ponnuru and frequent contributor Veronique de Rugy). Think Progress acts as if this is some sort of revelation, but this sort of thing has been common for some time, particularly on the left. The Environmental Grantmakers Association is one example of an organizational umbrella for like-minded philanthropists that has sponsored closed-door conferences for strategy discussions, but there are others. The Kendall Foundation, Pew Charitable Trusts, and other specific funders have, at times, also taken very aggressive steps to ensure coordination by funders and grant recipients. I wrote about this fifteen years ago in my book on the environmentalist movement. Next thing Think Progress will tell us there’s gambling in Atlantic City.
