The answer's really very simple - each mention of his name sends a subliminal message which cannot be ignored or overridden by actualities. People hear/read "Newt" and they automatically associated it with "Fig Newtons," which leads the brain of the average conservative to "Fig leaf" which, in turn, takes them directly to the Garden of Eden. Newt Gingrich then becomes a man of biblical proportion. How can you not like him? He's god-sent.
