I must ask you. Where did you learn this?
Answer: Watch what he does, not what he says. His speeches, his body language and his contact with his opponents in debates is especially revealing of what I said. In addition, watch for his general lifestyle over decades--it is of an upwardly climbing person whose principles and policies are in constant flux as demanded by the conditions he faces. For example, he has recently sealed all his papers as governor for 10 years!
I don't think he is difficult to understand at all. He is the Sammy Glick of politics and his opponents are aware of that, but don't know how to address it.
