When candidate Clinton says: You should be willing to campaign for every vote, she's making it clear that she refuses to let delegate numbers deter her from running. It also sounds to me that the same logic compels her to continue running, regardless of who gets the nomination. And, if there's any question about any counting irregularity, she may well keep fighting past the point when the general election has been called.
At times, her determination reminds me of the Energizer Bunny. Other times, Chucky.
