Political science has its laws, and they can predict what will happen in politics. One such law can predict whether George Bush will be reelected President in 1992.

It is true that political science is not politics. This relationship between the two is no different than that between any science and the reality which it analyzes. Every science is a repository of abstractions which model the critical aspects of a much more complex underlying phenomena. While some political scientists have expected a one-to-one, deterministic relationship between the science and the material it studied, most anticipated the “deterministic randomness” (or “chaos”) paradigm becoming popular even in the physical sciences today. Deterministic, because the science assumes that there are intrinsic underlying laws; but random because, with the inherent complexity, much will necessarily remain unpredictable (in statistical terms, that there always will be an “e” in the equation).
