The Most Puzzling Issue Concerning the Foley Scandal

Why in the world does Rep. Hastings go by "Doc"? Who runs for Congress with that name? And then wins? Richard Norman Hastings had a nice Congress name. It sounds like a solid American. Dick Hastings is a good Congress name. Nothing wrong there. The name "Doc" to me (and I'm sure I'm not alone in this sentiment) means either one of the seven dwarfs or the name of a small business owned by a man who enjoys hunting and NASCAR (something like "The Lube Doc").
