The phrase "Liberal media" is laughable. What it is, is it's a corporate media. Some of it's somewhat "liberal" some of it's somewhat "conservative", some of it's strongly one way or the other, but most of the mass media in the USA fall into what the rest of the world would see as a pretty right wing mode. The game, though, is to divide the public into self-perceived "liberals" and "conservatives" and keep them fighting with each other so they won't get the idea of joining forces and fighting the system itself.
