I am sort of confused. Are you saying that Fitzgerald is going to name Cheney as an unindicted co-conspirator?
If Libby and Rove tell totally consistent stories then the folks who are inconsistent with either one of them are in a bit of difficulty.
Miller was needed to validate Libby's story, for example, because that puts the nail in Cooper's coffin, and with that, certain statements made internally to the CIA (without external circulation) become highly suspect.
With Wilson not being a CIA employee, it would be Plame, or someone closely associated with her, who is the source of the inconsistencies that grabbed Fitzgerald's attention. That individual may well have "outed" a different undercover agent none of us know about ~ e.g., the person who provided the holographic copy of the papers on file in Niger supposedly showing Saddam Hussein's interest in yellowcake.
It's absolutely amazing so few folks have ever had any interest in the only spy in the game.
