Bill Keller-Blair
Are they married?
Seriously, Keller was the replacement for Howell Raines, who was Blair's sponsor. In my opinion, the Times' editorial slant is being driven by Pinch Sulzburger and not by any of the editors. If he is not replaced, the paper will only continue to lose ground.
The only good thing about it is that this administration doesn't pay attention (particularly now that the State Department and CIA are being purged). As a result, the Times will only lose impact throughout the next 4 years.
May's response letter, invoking Bill Safire, may provide a clue to Safire's departure. He simply may be getting too much pressure from the angry liberals at the paper.
