It's not like Flipper is going to do anything for Cory Booker and Newark, New Jersey if and when he becomes president. Bain Capital is fair game. If Flipper can defend their business practices that's fine, if not, the voters will decide. The same is true of universal health care and all the other policies Obama put into place.
Yes, Booker needs to get real. I don't think Booker understands how Newark gets ignored. He is perhaps unaware that affluent white people can ignore anything they don't want to be bothered with, such as black poverty in Newark. It's amazing, really, to me, that Manhattanites and rich suburban New Jerseyites can behave as if this city is invisible. It's like Oakland vs San Francisco or Berkeley but way way worse. To imagine that Chris Christie or Mitt Romney would ever deal with Newark except to make things worse is a pathetic fantasy.
