You may be right, as always, I can only speak for myself and my perception. I don't think he's a good communicator. IMO he was received with rock star adulation because of the man he is, not the speeches he makes. Which is a better way to be received. SO I guess we can agree on that.
Okay, let's agree on that :)
He delivers powerful speeches, many of which have been eloquently delivered. Judging anything he says by an occasional slip of the tongue is, IMO, shallow.
