Narcissistic Personality Disorder, displayed in some leaders, has a lot to answer for in history.  Having had direct experience in the workplace with some sufferers over the years, the best way to handle them is either to ridicule their excesses and their inflated ego if one can do so without direct consequences to yourself, or to ignore them and leave at the first opportunity.  The media has the advantage in the first scenario, by using satire.  Satirising overweight, silly men, one with a ridiculous hair style, and the other with ridiculous (if not 'camp') taste in medieval dresses and headgear, could do something to counteract their impact on those who are left vulnerable to their excesses.  Being laughed at is a special sort of hell for the NPD sufferer.
