There is nothing new about McCain's theory that US are winning in Iraq. The problem is, now we see something that is supposed to be objective analysis which basically says exactly the same thing. Under close consideration, this does not look good at all.
It does not really matter that this conclusion does not match with the actual situation on the ground, it was never intended for this purpose in the first place. What really matters is the way Dems will react to this smart GOP provocation.
