Does this happen much in sport? I see it a lot in music, acting and business, because nepotism is so easily perpetrated there, just as in politics. Sports I can't think of any familial dynasties. Might just be because I don't really like sports but when have there been 2 players who were the pinnacle of their sport? In fact, even in music we see manufactured dynasties but rarely organic dynasties (eg. Julian Lennon was nowhere near as popular as John Lennon but he nonetheless got a hit record). It all just suggests that these are orchestrated, oligarchical results, rather than the result of healthy democracy.
