Win Myers links to an essay by William Schambra on the manner in which blogs can shine light on the role ostensibly neutral but actually left-leaning foundations play in the public policy debate. Schambra rightly credits Win with helping break the story of the "philanthropic" role in generating the astroturf roots of agitation on behalf of campaign finance reform, though I think he mischaracterizes him as a "scrappy, individualistic insurgent" "relatively unfamiliar" with the field of philanthropy. I’ll grant him the scrappy, but not the other descriptors, at least not without qualification.
Hat tip: Hugh Hewitt.
Update: Heres an on-line version of Schambras article.
