@msolga,
I believe that if you would take the trouble to read Alexis de Toqueville's "Democracy in America", first published in the early 1830s, it would give you a fairly good understanding of some of the origins and historical threads that are at work here in this movement. It is a very good read on its own - the author contrasts the "top down" aspect of European (or more particularly French) governance under both the ancien regime and the French revolution with the intensely local, "bottom up" character of American governance and political views.
I'm not suggesting this encapsulates the entire character or motivation of this amorphous an not-well-organized movement (whether you regard its character as political, religious. or anything else). However, I believe it will give you an understanding of the historical roots of the public discontent with the probably benign and at least well-intended attempts of recent U.S. governments to extend modern social welfare programs and their associated controls through the country.
Many here find it easy to denigrate these longstanding aspects of American culture. Indeed some rather too serious and self preoccupied academic types have attempted serious analyses of some aspects of all this. Richard Hofstadter's "Anti Intellectualism in American Life" is a good example. Basically it all came down to his inability to accept why all those stubborn, often religious, self-centered local yokels were more content with their own local community organizations than the intellectually better models that superiuor folks like himself wished to impose on them.
In turn perhaps you can explain to me Mr Rudd's sudden fall from power and the apparent discontent of Australian voters, left and right, with recent governments.
