People who have no credibility probably shouldn't present themselves as authorities on credibility. Talking to reporters in Argentina today, Bush said, "The way you earn credibility with the American people is to set a clear agenda that everybody can understand, an agenda that relates to their lives, and get the job done. And the agenda that I'm working on now is one that is important to the American people."
An agenda that's important to the American people? You mean you're going to resign?
Now THAT would be incredible.
