Peggy Noonan, whom I seem to agree with more and more these days, weighs in on the McClellan business in a piece titled - as Bigby asked in a previous thread -  “But is it true?”:

The left, while embracing the book’s central assertions, will paint him as a weasel who belatedly ‘fessed up. They’re big on omertà on the left. It’s part of how they survive.

The right will—already has—pummel him for disloyalty. But those damning him today would have damned him even more if he’d resigned on principle three years ago. They—and the administration—would have beaten him to a pulp, the former from rage, the latter as a lesson: This is what happens when you leave and talk. …

When I finished the book I came out not admiring Mr. McClellan or liking him but, in terms of the larger arguments, believing him. One hopes more people who work or worked within the Bush White House will address the book’s themes and interpretations. What he says may be inconvenient, and it may be painful, but that’s not what matters. What matters is if it’s true. Let the debate on the issues commence.

Be nice if it did. But I think the state of our political discourse is too far gone for that to happen.
