 "America votes" is also a synecdoche because America is a whole of which the people who voted are a part.On the other hand, "The White House said" is metonymy, but not synecdoche, for the president of the United States and his staff, because, although the White House is associated with the president and his staff, the building is not a part of the people.Similarly, metalepsis is closely related to and sometimes understood as a specific kind of metonymy.
