As Josh Marshall points out, the Bushists view the enemy to be, not truth, but silence:

Virtually all of the arguments the White House is now advancing are transparently ridiculous on their face to anyone who has closely followed this evolving debate over the last three years.
But that doesn't matter. The White House doesn't need to win any debates. What they need is for their core supporters to have something to say. Anything. And to be able to say it loudly. The one thing that would be fatal for the White House from its defenders would be silence.
I don't say this as a counsel of pessimism or futility. It's just important to understand, to know what they're trying to achieve. The good news is that most Americans have already figured this out. Clear majorities of the public now believe this president misled them about Iraq. And they'll certainly grow. The key is to press these on the specifics, why they said these things they knew weren't true.
