I noticed this a little at the Alabama speech and bigtime last night. He is really modulating, becoming more polished and conversational. Its all good.
"If you are coming, makes it seem you are going away. If you are small, appear large. If you are weak, appear to be strong."
What I might call the rule of opposites.
He appears to be a clown and, perhaps, even not so smart because it confounds his enemies.
When his opponents finally begin to catch on, it's too late...he's won.
This is not to say that he is not an original article...he most certainly is.
But he is a fighter and he wants to win.
Americans get Trump, but his enemies are completely flummoxed.
