The Power Behind the Shutdown
Heritage Action for America is frequently cited as the place where the House of Representatives' shutdown/default strategy was conceived, and they have been very active in promoting it and threatening Republicans who deviate from their party line. So who are they? Sourcewatch takes a look.
Their analysis sees a collection of right-wing foundations, with a little help from some Korean, American, and Taiwanese corporations, though individuals also apparently contribute.
Sounds to me like the usual agents of the oligarchy - or, as Hillary once put it, the Great Right-Wing Conspiracy.
