I found this wonderful passage while reading the collection of essays "All Things Considered." Chesterton was English, but he could easily be writing about the USA.
It is from the public domain essay The Boy.
"Can any one on earth believe that if the seeing and telling of the whole truth were really one of the ideals of the English governing class, there could conceivably exist such a thing as the English party system? Why, the English party system is founded upon the principle that telling the whole truth does not matter. It is founded upon the principle that half a truth is better than no politics. Our system deliberately turns a crowd of men who might be impartial into irrational partisans. It teaches some of them to tell lies and all of them to believe lies. It gives every man an arbitrary brief that he has to work up as best he may and defend as best he can. It turns a room full of citizens into a room full of barristers. I know that it has many charms and virtues, fighting and good-fellowship; it has all the charms and virtues of a game. I only say that it would be a stark impossibility in a nation which believed in telling the truth."
