The Russian fake news effort go the voter lists from the GOP, they knew exactly which voters to target and they augmented them with Data Analytica profiles too.

But I think people overlook the coordination that these stories had with the campaign. Trump's message was always touching on the most prevalent fake stories, and those fake stories would always reinforce what Trump said at his rallies. The Russians and Trump worked in harmony for the last few months of the campaign. That type of coordination doesn't just happen by one side playing off the other side, it happens when both sides are talking every day. I have zero doubt that Trump's campaign was vetting the fake stories daily and helping plan their timing and messaging. It was all way too synchronized to just be an independent group trying to help a candidate without their knowledge.

It was an incredibly powerful and effective method. It would even play on real news stories with stuff like, "Here's the rest of the story about Hillary's fainting spell." Then Trump would have a couple key points from those stories that he'd hammer home and it would look like the truth.

Right now you're seeing the Reps flounder so far in the mid terms and a large part of that has to do with Facebook cleaning up their platform.
