Why, what was in the emails to implicate her? So she was irritated in private that Sanders was being a dick and his campaign was incompetent and blamed the consequences of that on her. Is she not allowed to have emotions in private?
If she resigns, it's an admission of guilt and caving to Sanders when she has done nothing wrong. Shame on Bernie for taking advantage of public confusion over these emails to mislead everyone and continue his personal witch hunt against DWS.
DWS publicly insisted multiple times that the DNC was neutral, which turned out to be false.
My company is neutral in the contest, that doesn't mean my personal feelings have to be, just me actions on the behalf of my company
