Could it happen here?

Just had a quick look at a couple of Spanish papers to see their take on the American elections, although of course they went to press before Obama's victory was definite. One interesting piece in El Pais quoted Carl Meacham who is described as principal advisor to the United States Senate on External Affairs and himself a child of an Afro-american and a Chilean. He asked could this have happened in Europe, in Spain, for example? Could Spain have elected a President who is half Spanish and half Ecuadorian, Dominican or Marrocan? I think the question was meant to be rhetorical and could equally well be posed-and in the same tone-to other European countries.
