Tip of the Iceberg? That's what investigative journalist Murray Waas concludes about the latest story that several conservative pundits were on the take from lobbyist Jack Abramoff. There are, of course, entire blogs and websites that do little more than regurgitate K-Street propaganda (there's even a term for it: "astroturfing"), and outlets like FoxNews and the Heritage Foundation pretty much exist for the purpose of providing a veneer of legitimacy for a specific point-of-view. Until I see evidence to the contrary, the presumption should always be that any Beltway pundit is on the take.
