I would say that it is not that Hennigh does not sound optimistic, but rather that the host carefully chose the sound clips to ensure the tone supported Nadler. In my opinion Evolving was the victim of a set up. Quinton has never before been involved in such a negative interview, and judging from the various sound clips (each had a different sound, leading me to believe the interviewer added in her comments, likely very different from the ones Quinton heard, in post processing) and the rather cheerful tone in Quinton's voice, he likely thought it was good PR (even the title was misleading)...

Was it set up for Nadler to further his agenda??? I wonder if Kitco made a donation to NPR recently?
