Ayn Rand in a bush jacket?
I understand what you mean. Left to his own devices, without the steadying influence of a co-author, Pournelle's politics infected his work with an authoritarian heavy-handedness. I'm not referring to the military theme of his stories, but the philosophy behind his stories, and which animated his characters.
Pournelle was popular with some of the conservative Zoners, especially TB, and they seemed to approach him as a sort of cross between Heinlein and Ayn Rand...a guru in a bush jacket. There are people who are mourning Pournelle right now.
