[Update]: If you find yourself in the unfortunate position of discussing this case with a conservative so deeply in denial that his clearest rebuttal is "No one violated the IIPA", point them here. A very kind a patient soul has boiled the story down to its component parts, and has even included friendly little pictures to make it VERY easy to understand. Enjoy.
Think Progress has a great list of "Right Wing Myths" about the Plame leak available here.
Pay them a visit if you'd like to brush up a bit on the story thus far. Chances are the RW noise machine will kick back into high gear when Fitzgerald does what ever it is he'll do, and unless you've been a total Leak Junkie you may want some advance prep on the established spin.
'Cause, after all, you never know when the Bushie in the next cube will decide to "set you straight" on this story. Shudder.
