She is just a symbol of the rest that likely didn't like what happened for a myriad of reasons. I suspect she and the other disaffected Bernie-Followers, not just bros, were butthurt and used the Hillary/DNC(culminating in the lawsuit mentioned above) stuff to express their sadness in the loss of their guy. Probably why the backroom deals are/were(historically) made.
Bernie Sanders - Also likely selected by Hillary, DWShultz, etc, to be her foil in her coronation to the nomination.

Just for the record, not goal tending the un-goal-tendable but nevertheless:
PotUS being incredibly short-sighted PotUS. He made the judgement to release it as PotUS while likely giving away uber secret satellite intel, etc.
Hillary, while intent was not measured or not able to be measured according to Comey, wasn't in the actual position as PotUS to have the legal framework to release such pictures or Classified documents even as SoSUS. This because she hasn't been and likely will never be PotUS. But you know that. BTW, there are few if any R's, even reluctant current R's, left on the site to drown out the crickets.
