When they keep admitting by accident that left-wing Democrats are right, about everything, always.
Outsourced to Matthew Yglesias:
Matthew Yglesias: You Don't Say: On the one hand, it's a huge deal that former White House press secretary Scott McClellan is now out there admitting that the Iraq War was a mistake sold with lies. But on the other hand, it's sort of banal. We've known this for years. It's a shocking truth about our current state of affairs, but not a truth that any longer has the capacity to shock me.
On the other hand, this from Byron York was interesting:
One of the main reasons John McCain is facing such an tough job today is that we are now in the sixth year of a war that the president of his own party started by mistake. That's a major headwind when you're running for president; an error of that magnitude will exact a political price. Would anyone be surprised if voters say that they've had enough?
That all seems reasonable enough to me, but what York is missing is that McCain doesn't think it was a mistake. One would think the virtue of nominating a guy who doesn't have close personal ties to the Bush administration would be that McCain could say something like "hey, I think liberalism is wrong and conservatism is good, but that doesn't mean I'm a sociopath who loves war so much that he still thinks the invasion of Iraq was a good idea." But he doesn't say that, presumably because he doesn't believe it. At even a time when the chief propagandists of the Bush administration are willing to admit that there BS was BS, he's a true believer.
