I think 'St. Norman of Geras' has found the answer to that question via 'Talking Philosophy'. In essence, a school has an election for student president and tells the young candidates that they must make a speech on closed circuit TV. The earnest and seriously-minded students deliver speeches promising this or that improvement to the school's ambience but one shrewd youngster says nothing and instead plays his guitar for his allotted time and ends with just two words, "Pick me!". He wins, of course, which allows 'Norm' to sort out the ethical and moral bones of the episode with his usual care.
I like that story even if it does show up the glaring gap in my previous two posts in which I floundered about attempting to list the skills required to be a successful president of the USA. Of course, I should have added what is really the critical element without which no statesman ever reaches the highest pinnacle - guile! Wonderful word, that, "guile"; it is defined in my OED as "sly or cunning intelligence". I don't much care for the "sly", which has sinister undertones, but "cunning intelligence" exactly sums up what every political leader needs.
