I seem to recall reading, around 45 to 50 years ago, a science fiction short story or novel where one of the plot mechanisms was that anyone who wanted to run for political office was automatically declared insane, and thus unfit for office. Thus leaders were to be selected by some other method (Sortition? or by computer?).
The story was not "Franchise" by Asimov, about a randomly chosen voter (I just checked by re-reading it).
