Talk about a jaw-dropper. The favorite book of an American presidential candidate was written by a radical journalist described in a Soviet document as an “agent of influence.”

CBS Evening News last night ran its weekly special, “Primary Questions: Character, Leadership and the Candidates.” Katie Couric’s question to the presidential candidates was, “If you were elected president, what is the one book-- other than the Bible-- you would think is essential to have along?”

John Edwards chose I.F. Stone’s “The Trial of Socrates,” because “he talks in a very thoughtful way about the challenges that are faced by men about character, about integrity, and about belief systems. And, uh, and the book – I’ve read it several times. It’s had an impact on me.”
