In his acceptance speech in 1992, American President Bill Clinton described Professor Quigley as his mentor and an important influence on his life. Quigley wrote several books including 'Tragedy & Hope: A History of The World in Our Time'.
On page 1247 he went some way towards exposing the charade that is the two (main) party political system.
"The argument that the two parties should represent opposed ideals and policies, one, perhaps, of the Right and the other of the Left, is a foolish idea acceptable only to the doctrinaire and academic thinkers. Instead, the two parties should be almost identical, so that the American people can "throw the rascals out" at any election without leading to any profound or extreme shifts in policy."
