A lot of people are asking what Justice Kennedy's references to "millennia" mean. The short answer is that we really don't know because so far, the people blogging have only seen Justice Kennedy question one side in the case, so we don't know how he will address the other side. The normal practice is for Justices who are thinking hard about a case to ask questions of both sides (Kennedy often does, the Chief Justice too), so I wouldn't read very much into it. Obviously it's not as clear a signal as if he had said, "You are clearly right," or "You are clearly wrong," but such clarity is rare.
