I have always wondered if the leaked documents about Clinton carried a bigger impact on the election compared to the leaked Access Hollywood tape recordings. Both leaks was intensely written about in international media, discussed on social networks, and framed much of the political advocacy of both camps.
For an alledged "data analysis guru" Robby Mook doesn't seem to have much, or anything​, in the way of a technical background.
After something happens, write a book saying that someone predicted that something would happen, ignoring the other people who thought that something else would happen instead.
Clinton also won the popular vote by 2,864,974 votes. A few tens of thousands of voters in a couple states would've turned this entire narrative on its head. Flagged for the same reasons that all of the other—sometimes much better—political articles that end up on the front page get flagged.
If Trump lost the elections, we would get a similar book about his mistakes and his campaign's ineptness.
It was a polarising and dirty race.
