Why do so many people believe that winning an election is more indicative of "merit" than hereditary succession? Where is the evidence for this widespread belief? And why should anyone have more confidence in the wisdom of the electorate, who just happened to be born in the right place and time and didn't do anything to be qualified to vote other than be 18 or older, than in that of one person, who just happened to be born in the right place and time and didn't do anything to get into the royal family? An individual might be good and wise, or he might not. A majority of the public? Far less likely. And the sort of person who wants and seeks the highest office in the land--something dictators and elected presidents have in common, though their means differ--is precisely the last sort of person who should be entrusted with it.
No divine right monarchist has ever been more mystical and unscientific about Royal Blood than republicans are about Elections and Public Opinion.
