Keep in mind, though, that in a courtroom he is not dealing with your average person . . . he's dealing with twelve jurors who have been selected from a large pool of "average people" -- and the lawyers themselves were part of the selection process that reduced the pool from 100 or so down to 12.
You'd probably find that a typical "summation" or "closing argument" is aimed at someone with an eighth-grade education and an IQ of 85.
Where were the case(s) tried - in the South, urban/rural, wealthy/poor. This looney-tune may have a larger appeal than he's being given credit for. From what I've heard - he is a dynamite public speaker & gets the crowds excited. Something like a good lawyer in closing arguments.
There are many here among us that think he is but a joke. A truly damgerous attitude - attack an image, not the ideas.
