Well, well: NBC News obtains August 2015 Clinton-DNC memo read this important caveat:

[ehrnst]

154. There were two separate staffings - one for the primary, one for the general

Prior to September the DNC Communications Director was Mo Elleithee.

After September it was Luis Miranda,where she says""I am grateful to DNC Chair Wasserman Schultz for asking me to serve at this historic moment as the American people prepare to elect their next president,” said Miranda.".................. "I am proud to join a DNC team that has been critical to those successes, and that is working to elect a president who will keep America moving forward.”

And then this "“I am thrilled to announce these new members of our communications team,” said DNC Communications Director Mo Elleithee. “With their wealth of communications experience, these new members will help us aggressively take the Democratic message to a wider audience as we work to help elect the 45th President of the United States and other Democrats all across the country in 2016.”

So that could be entirely true that they hired the Communications Director for the General in 2015 and had a separate primary one.

You seem to think that there is something very wrong with the Democratic leadership - which gave Bernie's campaign the Party credibility that the Green Party could never have.
