As far as Bernie v Data:
Regardless of how "in the wrong" he is, the DNC dramatically overstepped its bounds in locking them out "indefinitely" when the contracts state they don't have that authority.
If you've been following the DNC for any length of time you know that DWS is kind of an idiot, she couldn't even answer on live television what socialism is. She worked on Hillary's campaign, and the decision to lock the Bernie campaign out of their access - after the breach was already over - was her sole decision.
The Sanders campaign clearly did wrong, but the DNC knowingly tried to fuck them in ways that they should not be able to. The argument for a coronation has legs.
