Stephen Colbert of The Daily Show did an online chat at the Washington Post the other day. His answer to an accusation of liberalism on The Daily Show was perfect:
First, we are not news. We are under no compunction to be fair or balanced or any other thing other than funny. Second, satire always attacks the status quo. The status quo is presently a Republican executive, legislative and judicial branch. There's hardly a liberal target left. Third, we throw hay makers at the Democratic candidates across the board. Fourth, I hope Bush loses.
