I am quite liberal but I don't understand why anyone gives a shit what idiots like Maher, O'Reilly, Coulter, Behar etc say. They're all talking head idiots who just want to be famous and make money. They don't know any more about politics than the rest of us.
Maher is well-informed and had a sense of humor. He therefore can put it all together and make a joke of the insanity, perhaps even make you see an issue more clearly. Not everyone can do that--not even the politically astute. I like him and his funny, politically aware cynicism.
