Having waited a long time for the press corps to overtly revolt against this vile tradition, allow me to suggest another possibilty: What if White House reporters just started anonymously outing the anonymous briefers to bloggers? Just an idea.
Well, of course it's an excellent idea. And, it's happened at least once. And, Jack Shafer's been beating this drum for awhile.
Generally, there should be no anonymous sources in cases where those sources are simply pushing the official administration line. Period.
