Rudy Giuliani was on “Meet the Presstoday. Tom Brokaw asked him to respond to McCain’s assertion that Sarah Palin is the most knowledgeable person in the country on energy:

MR. BROKAW: "More about energy than probably anyone else in the United States of America." More about solar, more about wind, more about geothermal than the MIT scientists who are working on this initiative? Boone Pickens? Senator Al Gore? Do you think she knows more than any of those people do?

MAYOR GIULIANI: I think John was referring to elected officials. He, he would not be referring to Boone Pickens and certainly wouldn’t be referring to nuclear scientists and people like that. I think he was talking about politicians and probably, in particular, the people involved in the race.

So "knows more about energy than probably anyone else in the United States of America" means "knows more about energy than Obama, Biden, and I."

Even thus narrowed the claim is still absurd, but honestly, how stupid do they think we are?
