I am not sure he understands the public in general, after all he lost the popular vote.  His speech was a distillation of his campaign I would agree aimed at his supporters, which how those 12-13 year olds I taught used to behave - aimed at those who "followed" them.  I am not sure of his honesty, as so much of what he says is demonstrably false; what scares me is that he may believe that they are true.  His language is aimed at the reality TV audiences and delivered in the same way so yes it works to get him elected, but will it allow him to govern?
