Some fun facts: Zuck's favorite book(s) growing up was the Ender's Game series [1]. He learned Mandarin and spoke to Chinese audiences [2]. As such, I don't think he's setting himself up to be POTUS, that seems too small for him. (One of Zuck's role models is Bill Gates, and Bill clearly believes that folks like himself can do more for the world outside of Government than inside it.)

IMO, Mark's setting himself up to be Hegemon of Earth: http://enderverse.wikia.com/wiki/Hegemony
