I don’t think he was ever running for President. I think he was realizing that Facebook CEO is a position of more political influence than perhaps even the US President.
Zuckerberg can’t launch nukes but he can manipulate the emotions and attitudes of entire countries and societies. In many way his power is more terrifying because he can exercise it in secret and with no repercussions. I mean, if this Cambridge Analytica story is to be believed, he had a large influence in selecting Trump as president, and continues to have this power even if Cambridge Analytica does not.
