Aloha Juliana!

What she was saying was that the primary was essentially one that the Carter Center wouldn't have even declared free, fair, and democratic.  That is worthy of being upset about and taking action on, especially when the ramifications are so profound.  By defrauding all the Bernie supporters Hillary has lost any legitimacy that primary processes are supposed to achieve.  But mainly, I think it's simply wrong to her how she *should* feel.  That tactic can be seen as a failing one in interpersonal relations as well as party relations.
