Polipundit, not real familliar with that blog, opines on the inflated Performance Reports. It's a good read and educated me about an era I don't know much about. I can tell you what they were like from the mid 80's to the mid 90's, and somewhat beyond since I still have friends who are AD.
Guess nothing has changed since then, since John Kerry's top rating put him in the top 50%. But then I figured that already.
