My money is on Joe Biden as the one who outted Valeri. Wouldn't it be great to expose a prominent dem. The mere fact that these "principled" journalist and their organizations have not come out earlier to expose a Republican is prima facia evidence that it is a dem.
My money is still on Joe Wilson, but I think that some State Department Marxists and other Democrats may have also had a hand. Everything points to the Democrats. I believe somebody set a trap, and the rats (including their accomplices in the press) took the bait.
I think Novak confirmed that his source was a "senior administration official."
