I don't believe it.
The Russians have nothing to gain by releasing emails that damage Hillary. After all, she's been working with them and got them a uranium deal. also, the Russians would sit on the emails and use them to blackmail Hillary if she was elected.
Bernie supporters, on the other hand, have known that the DNC was totally screwing Bernie and his supporters. Hacking the DNC emails and releasing them gives them the proof and exposes the DNC fraud. Schulz has already been fired and there is a good chance will be replaced with a "Bernie-friendly" alternative.
Short answer - Russia has nothing to gain by this but Bernie supporters have everything to gain and nothing to lose.
The only thing Russia made have to do with this is that they are in contact with US Commies and may have supplied the code, but for other reasons (like hacking a Republican). I would bet my house that there are Bernie supporters with Russian contacts.
