I'm not sure that that's true, actually. I mean I don't think that people 'attempt to elect the smartest President because common logic says a smart person will make better moves than a dumb person.' George Bush got elected twice despite the fact that, particularly in the first contest, his opponant was clearly a great deal smarter than him. Call me a pessimist but I just don't think democracy (particularly American democracy) works like that. I think that being smart puts voters off.
But then, sheer brains is not the be-all and end-all of leadership anyway. The funny thing is: the Wilkerson's seem to think it is. And seem to think that everyone else thinks so!
