Fitzgerald has blown this case.
Now I'm seeing rumors from DU, Daily KOS and ABC that Fitzgerald might convene a new Grand Jury to present information he received from Woodward. The RAT spin is that the Woodward revelations will allow for the indictments of others. Were that true then Woodward would have been pressed to reveal his source.
IMHO: the new GJ is cover for dropping charges against Libby.
