It follows that the voters in states that Clinton won overwhelmingly are going to question any superdelegates who endorse him.

It also follows that voters in states in which the race was close don't have much cause to question the choices of the superdelegates based on the results in their state. That could be a factor, but other factors may be given more weight.

This statement is not a call for superdelegates to go with the one who has the most pledged delegates on June 15. It is not a "rail" against superdelegates.
