O'Donnell predicted that a couple of people would be indicted in this case.
I can't stand O'Donnell, but he was the first person to identify Rove as a source for Cooper, from Time magazine.
O'Donnell also wrote today that Rove received a target letter because Rove's lawyer failed to deny receiving one. He just did so today (that is, Rove's lawyer denied receiving a target letter). So O'Donnell has no more inside info than we do. He's just speculating. People who speculate are sometimes right, and they're sometimes wrong.
Could this be the reason why W picked Miers just in case Rove or anyone else is indicted? That way there would not be two major political battles this large going on at the same time? No tin foil, just a thought.
