You got me...cheap shot though ;-)
Politics (and I suppose political science as well) is said to be the "art of compromise...hardly a science.
There really is no room in science for compromise...although rules may change as new evidence presents itself and after a thorough scientific revue.
Political science is in Aristotle's [or Plato's, or both] school category of Practique, as opposed to Science [which includes religion, maybe a surprise to some].
