The nazis and the communists seem all the same...yet are they?
Yet they're on the opposite end of the spectrum.
Why do liberals so often quarrel among themselves...or do they?
How come the 'left' and 'right' terms are used so often, yet when it's time to band together the alliance so bitter?
This means politicians are all corrupt and are just out for power...maybe.
But think
again. There's more to it, that "meets the eye".
Jerry Pournelle seems to have made a measurement systems that finally puts thing into their corner and we can be eye-to-eye with the idiosynchracies polluting our election and governmental system.
