The problem I see with books such as the one you cited is, they could very easily be considered partisan hit pieces without much more than insinuations and allegations. Consider Schweizer's hit piece on the Clinton's. The only "evidence" he had was a "pattern of criminal activity".
So the question, is "House of ..." just another hit piece or does it have real evidence????
