White House Insiders Who Turned Against Bush

So many former insiders to the Bush administration have subsequently exposed him that we need to invent a distinct term for the role, and perhaps even for the books they produce. Submit your own terms of praise or abuse for the exposé work of these insiders-turned-whistleblowers. You could rate these [insert term here] on any number of criteria: credibility of the exposé, extent of the damage, value of their speaking up, even quality of their writing, whatever. No doubt there will be MANY more to add in the near future, and others I have missed, so let me know.
