What I love is the apparent role reversal - PBS on it's head. Dean is playing the role of the liberal-annointed stereotype of a conservative - loud-mouthed, easy with the facts etc. Perl, on the other hand, sounds like a PBS personality - quiet, easy going, hence a supposive hook on reality etc.
Of course the Dems have more-often-than-not been the loudmouth, emotionally-charged and intellectually-bankrupt crowd, while the right has been the voice of common-sense reasoning.
