It's been a long time since I read quite so much comment about a speech - particularly one from a politician.

But what has fascinated me, is that much of the comment has been about the mastery of the delivery rather than the content, the message and the politics.

I'm using the speech as pre-course homework for a presentation and speaking skills workshop that I'm running later this month, as it demonstrates some superb skills.  

Watch the video and feel free to comment on what speaking and presentation techniques he is using.  (Opinions are appreciated, but we're only interested in the speaking techniques - not the politics!  Thank you.)
