They will probably indict Wilson, Plame, and Judith Miller.
Wilson, Plame, Miller, and one or two CIA bureaucrats. (Let's not leave them out!)
I hope you're right. I have to say that the two times I've seen Bush comment about this investigation, he didn't seem even slightly concerned about it. The first time, he sounded like he thought the whole thing was mildly amusing. Then yesterday he said "this is a serious criminal investigation", but he didn't sound worried at all. I hope that's a good sign. If I had to pick the most likely person to be indicted for perjury or obstruction, I'd have to pick Miller, especially with the NY Times now keeping its distance from her.
