Bernie’s supporters are the young idealistic “true believers.” They are ready to storm the barricades in Philly for their saint. If he backs down now, and tells them to support Clinton, they will be as devastated. As much as they would be if the pretty girl down the hall played the “nice guy but” card on them (not that the pretty girl down the hall would ever have talked to them to begin with). But it’s the same effect; their first political crush will turn out to be just another rank politician like the rest of “the machine.”
I say they stay home in disgust.
They might vote libertarian. Another possibility is that a good number, who aren't politically invested, will vote for Trump. I just can't imagine that hillary will get overwhelming support from them. They want change.
Oh darn.
