I wonder why?
The Times hasn't mentioned the W.H.I.G. because The Times was part of the W.H.I.G. disinformation campaign to sell the Iraq War by planting stories in the press. In Traitorgate, Valerie Plame was outed not only for revenge, but to protect that operation, because the Niger uranium story was one of the planted stories. (Remember the crude forgery of mysterious provenance that the yellowcake story was based on?)
The reason it seems like they were all in on it, is that they were all in on it. All the Kewl Kidz, and all the media whores. The whole Beltway 500 crowd is dirty. (Not you, Dan Froomkin, and not you, Walter Pincus.)
