There is speculation that the Powers That Be of the Right see her as a liability, particularly after her unhinged performance over the Frost family (which goes on, unabated, on her blog), and she was encouraged to resign. Unless there’s a new twist I don’t know about — it’s not like I actually watch Faux Snooze — the Rivera flap happened over a month ago. Why quit now?
Update: I hope somebody posts a video of what Olbermann said. Hysterical.
