Some Bernie fans seem to be losing hope and are announcing they will vote for...

Great point. Actually the only thing that can possibly keep Hillary from locking up the nomination before the convention is the super delegates. Consider that if the super
delegates didn't exist and only pledged delegates counted, in a two person race the person with the most pledged delegates after all of the primaries and caucuses are over is automatically the winner. Given the proportional nature of the delegate splitting, once one candidate is well ahead, as Hillary is now, it is very difficult for the opponent to catch up.

However, to cinch the nomination before the convention without the super delegates, a candidate has to win not only half of all of the pledged delegates +1, but also enough additional pledged candidates to equal half of the super delegates. That is a higher hill to climb.

However, if Hillary enters the convention with any kind of a pledged delegate lead, there is no way that the super delegates are going to suddenly give the nomination to a non-Democrat. I have my doubts whether they would give the nomination to Sanders if he had the pledged delegate lead entering the convention - but that isn't going to happen.

Bernie is singing the song of a beaten candidate.
