And maybe they don't.
Fox News is hardly the conservative megaphone we might like it to be and it certainly isn't the Republican party propaganda outlet the left pretends it is but Fox News is far from 'liberal' and those who make that claim are being unrealistic and unappreciative of the fact that Fox News does give the conservative point of view a voice, even it it isn't the video version of FR.
Actually, I was just being sarcastic, and should have labeled my comment as such. I have no use for the fools who criticize FOX as being “liberal” when they think FOX should be wall-to-wall right-wing propaganda (but only on the few issues the complainers care about).
