Hersh is an idiot. How someone can be wrong all the time and still remain an icon is truly a liberal phenomenon.
The description of Woodward is pretty accurate. I read "Plan of Attack", which was trumpeted by the left as a Bush/Iraq expose. Which was strange, because anyone who read the book could come only to one conclusion, that the US must to bypass the UN and invade Iraq.
Do you know offhand how often the journalistic stuff of his that sees print (as opposed to the loopy claims in speeches outlined here) turns out to be inaccurate? I've often heard that but never bothered to investigate before.
