Good,
Well, if it's a personal thing, I can give my own personal take on it.
To me, the idea that Harriet Myers quit because her boss "lost his marbles" is weak and self-serving.
Quite simply, and more to the point in my opinion, Bush will need far tougher legal counsel then what Harriet was able to provide. In light of a new Congress who will be far more aggressive, he will need very tough lawyers around him... not a mear work mom like she was.
