My take on this is that the relation between politics and the public has changed massively over the last 100 years and this seems to shape the sort of politicians we get. Today - as a politician - you need to be a media person, else you will easily look incompetent. This drives out mostly everyone who is not willing or able to handle the pressure of maintaining a public persona.
