Have you noticed, Pan17, that when DT reads a (speechwriter's) speech from the teleprompter, the tone and the vocabulary are strikingly different from his extemporaneous ( his own?) comments elsewhere?  Possible interpretation:  he doesn't understand what he reads as "his own" frame of mind and values (that the speechwriter was trying to convey), or that it's not actually his, but that of the man (whoever that is) behind the speechwriter, or that he doesn't remember what he read, so that he is easily able to counter what he said at another time.  A further one - mine - Beginning (?) dementia:  the trouble processing new complex info; the memory problems; substituting broad platitudes ("great", "unbelievable", etc), and being unaware of this, to explain positions or policies; inappropriate and impulsive behavior; rambling, nonsensical (his stream of consciousness) sentences; the delusions; etcetera, etcetera.  Oh, my comic book hero needs no defending!
