Is It Math or Electability?

I keep hearing from the media that it is over. If that is the case, why can't BO win and end the race outright. He cannot win without superdelegates either, yet the media portrays the race as if Hillary would be stealing the nomination if they made the determination that she was the stronger candidate. To make it clear, no matter what the lead is now, BO cannot get the nomination without superdelegates. They will BOTH be short, whatever the number. These are the facts.
