Actually, it was a card for Bill Clinton's August b-day sent early. The sender was George W. Bush, Grand Poobah of the Trilateral Commission, Crawford Division. At the Commission's meetings they wear tinfoil hats with steer horns. The secret password is Mooooo.
Wasn't Lee Harvey Oswald from Texas?
The plot thickens!
There is nothing about the Vince Foster case that would generate a tinfoil hat comment. This was a murder of the President's attorney. The guy who found the body says news reports of the position of the body were inaccurate; they couldn't find the bullet anywhere near where forensics indicated it should be, etc.
Someday, we may get an answer and I believe that answer will hold the answer to other suspicious activities of the Clinton's.
Believing that Vince Foster did not commit suicide (people don't shoot themselves with the 'off' hand) doesn't mean you've got the tin hat on.
