I don't think Miller is nuts, but I think she has her and her friends nuts in a vice. I think she couldn't care less about Libby, but she is part of a bigger 'conspiracy' with her other Georgetown buddies, Plame being one of them. A cadre of democrats who worked out a Langley decided to take down the President or the Presidents plans for invading Iraq. Now they have been found out. If Fitzgerald does his job he will almost singlehandedly take down the democrat party.
I think you are letting your hopes and desires cloud your thinking........but
I hope and desire you are right!
