McCain's pattern of factual mistakes on Iraq.
Then, yesterday, we have the fairly baldfaced misstatement about troop levels.
(Just off the top of my head, we should probably should add his April mistake over Petraes' purview, his April misstatements about the Basra uprising, and I'm sure there are more.)
These are facts he's getting wrong on his supposed area of expertise.
Of course he thinks we're going to win. He has no idea what's going on.
