Who cares? They are ALL related anyway. George Bush, Dick Cheney, and Barack Obama are cousins (true). All U.S. presidents, except one, can be traced back to the first King of England who was brought to England to assume the throne. (Windsor is not the real name of the royal family of England.)
How long before we learn that Newt and Romney are both descendants of the Duke of something or other?
No difference between Democrat and Republican, either.
