I've never bought the whole political angle to that film.
McCarthy was rabidly anti-communist. So it can't be both an anti-McCarthy film and an anti-communist film at the same time. I don't think it was ever intended to be either.
The horror aspect to the film is that once you get taken over you lose your individuality which is something we all subliminally fear. So I think it's actually a lot deeper than some trite political allegory.
