To paraphrase popular dog-training wisdom, There is no such thing as a bad topic, just bad hosts.  Well, that’s a little harsh.  But just about any topic can be compelling if the host truly cares and has something insightful/amusing/informative to say about it. Christmas tree — real or artificial?  That topic has the potential to be audio Sominex.  But in the hands of  TRN‘s  always acerbic Laura Ingraham this past week, it was pure gold.  Ingraham has a  VERY strong opinion on the issue (can you guess where she comes down on it?), an articulate producer who disagreed with her, and great callers, including the former CEO of an artificial tree manufacturer.  While the conversation had the light-hearted tone of a break-room chat, Ingraham did manage to inject her political view, noting the irony of Americans celebrating the love of Christmas with fake trees made in a repressive country like China.
