I've seen rumblings on how think tanks like the Heritage Group has a more active lobbying arm called Heritage Action, that spans the gap between Special Interest and PACs.
But, I was totally transfixed by this Fresh Aire interview of The New York Time's Eric Lipton about the details of policy institutes, as well as the revolving door and how Congress limits (or doesn't really) the reach of former staffers on the Hill.
Fantastic. Worth listening to.
