From Ed at ginandtacos:
I am not an unbiased observer, obviously, and I watch Fox the same way most people watch circuses or episodes of Two and a Half Men. Despite these handicaps I am confident that the following is a valid conclusion: anyone who watches this channel for multiple hours daily would be categorically insane after a few months. Everything about public opinion and the Tea Party and oddities of the American electorate make perfect sense after watching this for an hour or two. If this was your only source of news, you would become one of them. Your relationship with reality would be tenuous at best, and more likely nonexistent.
Any exposure I have to Fox News invariably leaves me stunned, indignant, and sad. Though, in fairness, I think that constant exposure to any 24 hour news makes one crazy.
