After watching yet another Democratic operative botch a he said/she said opportunity to move this story forward, I thought of two very good ways to hammer this story...
1) It's clear that Valerie Plame was a covert operative for the CIA when Karl Rove outed her. Otherwise, the CIA wouldn't have referred this matter to the FBI, and the Special Prosecuter wouldn't have pursued the case for the last two years. So the only question is whether or not Karl Rove knew that Plame was a covert op.
If he knew, he's a traitor. If he didn't know, then he was too stupid to find out before blabbing to the press.
So he's either a traitor, or too stupid to have security clearance. Either way, he shouldn't be working in the White House.
2) If the conversation ever turns to Clinton's impeachment, drop the hammer:
I'd rather have a President that betrays his wife than an Administration that betrays its country.
Now, how can we get someone on CNN, etc. to say this?
