The DNC was hacked by Russians. Shouldn't be surprising, and shouldn't be really under dispute.
I'm not so sure that the idea that idea
that Wikileaks is a Russian front is so out there, either. Nor a liberal one;
here's some conservative blogger making the same argument, and right-leaning (right?) Business Insider
covering the topic.
Certainly their agenda is transparent;
Assange said so himself. That's a swooning article from well-known Kremlin propaganda arm RT, where Assange hosted his own television show. WikiLeaks' general mission purpose is a little more inscrutable, but they're the group that curiously excludes Russia from its target list while
deriding the Panama Papers leak as a US-led hit piece on Russia and Putin (another Russian source, here). Seems like something apolitical transparency-minded idealists would do, doesn't it?
I have no particular feelings about Wasserman Schulz, but in spite of no real smoking gun in the leaks enough political damage was done in this well-timed leak to force her resignation as DNC Chair. The horror show that was the Trump convention had barely ended before this perception of Democratic disarray took over the headlines. That's an impressive result for Putin's agents and agitators -- whose bigger prize remains in November.
