What happened to advice and consent?

(Geek Warning) So I heard something interesting on C-SPAN radio over the weekend... no, really. It was an old (1992) interview with Senator Paul Simon about a (then) recent book of his -- Advice and Consent: Clarence Thomas, Robert Bork and the Intriguing History of the Supreme Court's Nomination Battles.

Transcript of the interview.

Two interesting bits: "We have through our history rejected one out of five Supreme Court nominees -- one out of four in the last century."

"You don't have to be a lawyer to be on the court, but there has never been anyone that's not been a lawyer... Justice [Hugo] Black said that we ought to have at least one non-lawyer on the court."

I'm not sure there is a point here... just some food for thought.
