Interesting that he's an ESTP though, as they would seem to be one of the last types to develop a stutter or speech impediment in childhood, as Churchill did, and one of the types less prone to depression. I agree with the typing, however I don't see the ESTP as a type that would hate school as Churchill did, or be as unacademic.
Additionally, is the ESTP the traditional type to inspire hope in a bombed out civilian population during the Battle of Britain? I suppose that's just a feature of a brillaint orator.
