The Anoka County Library has two items, which I believe are recognized as being of general interst for anyone concerned about wealth and income distribution inequalities. I have them on reserve and shall have a look.
Google Books is a helpful online resource. For the flavor of both books, see here and here.
I expect these books will present insights that Rupert Murdoch and Michele Bachmann and John Kline and whats-his-name Paulsen would rather you not delve into; each being more a KISS person, with simple and stupid being their formula for us, whatever their own limitations are. Regardless of the other three, Rupert is not simple or stupid. It's the hate against folks asking "wrong" questions that is the glue holding them together.
The other three enjoy having Bachmann and her always open mouth at play because each can be as egregious as Bachmann but she serves as their lightning rod when they are each being as awful in action as her, but lower key and behind the curtain.
Bachmann and Beck are the barkers. The fronts. I expect the Blue Dog Dems appreciate having Bachmann and Beck at high decibles as well.
