The DNC "hack" was an local insider whistle-blower (later killed - unconfirmed), the CIA and NSA info were also from inside whistle blowers. High impact.
The Macron leaks were most likely Russian, unfortunately with zero impact. One should really look what was exposed there. Then it went from there. The Russians really should have used Wikileaks as all others did. Their own attempts were all highly unsuccessful.
For example, I'm fairly convinced most fake news is about making a quick buck, not about actually influencing the illection.
How would you go about making a quick buck with fake news? Betting on Trump on the eve of the elections 4 to 1 (iirc) would be more of a gambling addiction than business plan.
This guy claimed he was making $10-$30k a month. There was another piece I can't find right now about a couple of college kids doing something similar. Fake news is wildly profitable.
