Skull and Bones Still A Bush-Kerry Secret

Ralph Nader has been campaigning at Yale in front of the Skull and Bones HQ, pointing out that Bush has appointed ten members or former members of the secretive Skull and Bones club to public office:

"We're dealing here with members of a secret society who presumably prefer each other in terms of advancing each other, recommending each other, appointing each other to public positions and enhancing each other's business deals," said Nader.

If Bush won't answer questions about Skull and Bones, Kerry certainly should. What is he afraid of?
