A much closer analogy:

A Hillary supporter would flunk the test, then complain he didn't understand that it was better to answer all the questions than just to put all effort into the questions he thought were more important. An Obama supporter would realize all the questions are worth dealing with.

And the Obama supporter would have studied the entire book--not just what he guessed the professor would test on. And therefore know far more about it than the pro- Hillary student did. And would not complain even if he didn't do as well as he had hoped on the exam.

It's time, however, for Hillary supporters to stop tramping in the sour grapes. The wine that comes out will not be one you want to drink.
