In reply to the discussion: Sanders campaign hints ‘hacker’ who accessed Clinton data may have been a DNC plant [View all]karynnj
(60,724 posts)Even a primary campaign means hiring hundreds of people to do functions that Bernie Sanders' staff would never have needed to do. It is not unlikely - or unreasonable - that they would have asked NGP VAN or the DNC for recommendations of people with who could do this specialized job. Remember that both the DNC and NGP VAN should be impartial and supportive to all Democratic campaigns.
I suspect that Sanders unlikely campaign has had a harder time than most building up the human resources needed to run a campaign. (At the other end of the spectrum, HRC started with a core of people who have been with her - and some with both her and Bill Clinton - for decades. )
I would guess that many people working for Bernie came from the various companies of professional campaign consultants. Some of them might not even personally prefer Sanders as President.
