I’m sorry but show me even 10 voters nationwide who were going to vote for Hillary, and then saw a Russian-created fake news post on Facebook and changed their vote to Trump. This Security Chief was clearly upset that his candidate lost, but blaming Facebook or the Russians is ludicrous. It seems that they
attempted to influence the election, but there is zero evidence that they were successful in changing the outcome.
I admire his devotion to his candidate, and for trying to find an explanation for her defeat. But sometimes the correct explanation is the simplest one: she was just unpalatable to many voters. Deal with it, and spend your energy finding a better candidate next time, rather than trying to blame Russia or Facebook for influencing even a single vote, which likely did not happen.
