I think his handlers figured out that if they keep him to boiler plate style campaign speeches he can operate on automatic and more or less steer between the lines of the teleprompter lane without instantly veering into the ditch. So they simply turned the SOTU address into one lengthy and meaningless campaign speech after pumping the nearly brain dead bastard full of uppers so that he was very nearly foaming at the mouth. Sadly funny or amusingly sad.
