I'm extremely concerned about the ethics around converting Facebook into an election machine. Three issues concern me:

1. Using the platform to push his campaign

2. Using the platform to suppress opposition press and views

3. Using the data analytics to gain an unfair advantage

Whichever party is on the receiving end of that candidacy has all rights to be pissed and somewhat concerned. It's not a fair advantage. Last saturday, my s/o got a push notification to watch Zuckerberg have a "drive about chat" with the mayor of South Bend, Indiana, so it's already happening.
