So, Was Scott McClellan Lying Before

Or now?

Is it more likely that McClellan lied for more than two years as press secretary for President Bush or that he's lying now to sell his book? And if he was lying before, is he telling the truth now to sell more books? Or get more appearances?

And is it any wonder that liar--er, sockpuppeteer Rick Ellenburg believes McClellan in any event? Why, in fact, do liberals only believe conservatives when conservatives say they lied previously? Does it have more to do with the flexible meaning of "truth" to liberals?
