For further reading on this subject, I cannot recommend enough the book Democracy Incorporated by Sheldon Wolin, which discusses his theory of inverted totalitarianism:

Inverted totalitarianism reverses things. It is all politics all of the time but a politics largely untempered by the political. Party squabbles are occasionally on public display, and there is a frantic and continuous politics among factions of the party, interest groups, competing corporate powers, and rival media concerns. And there is, of course, the culminating moment of national elections when the attention of the nation is required to make a choice of personalities rather than a choice between alternatives. What is absent is the political, the commitment to finding where the common good lies amidst the welter of well-financed, highly organized, single-minded interests rabidly seeking governmental favors and overwhelming the practices of representative government and public administration by a sea of cash.
