What to make of childless political leaders?

James McPherson writing in the Washington Examiner, makes a remarkable observation: the leaders of Europe have no children. France’s Emmanuel Macron has none. Same with German Chancellor Angela Merkel, British prime minister Theresa May, Italian prime minister Paolo Gentilon, Holland’s Mark Rutte, Scotland’s Nicola Sturgeon, and Jean-Claude Juncker, president of the European Commission. Sweden’s prime minister Stefan Lofven has no biological children.  This is a pretty odd coincidence and it makes one wonder what, if anything, it means.  Five American Presidents were childless:  George Washington, Andrew Jackson, James Buchanan, James Polk and Warren Harding.
