In 1775, most of the world's nations were ruled either by an absolute monarch, an elitist class, or through the practical application of brute force.
Then a bunch of middle-class colonists kicked the British off their land, and set up an experiment, which is still ongoing.
From the first days of the Washington Administration, competition and rivalry between factions and parties has been the standard fare of American politics. Lying, near-seditious gossip, and significant financial backing of preferred programs (Pork) has been the way of things. Reform has been attempted from time to time, but the devil always fights back.
When it seems like things are worse than ever, in actual fact they are just getting back to normal.
God Save The United States of America!
