No, this is not a discussion on global warming, the focus is the even older affirmation from many right wingers that mainstream media is liberal.
Many times I have made the point that if the mainstream media was liberal you would see them following the advice of important liberals in the USA, as it is, this item of the media covering the Greenhouse Gas Regulation that is being done by the EPA would be a good test to see what would the “liberal media” do.
Well, I would say that that does not make sense if the media was liberal, or more reality based. I still say that in reality mainstream media in the USA does follow more closely the biases of the corporations they belong to.
