If all the fake news was what decided the election, why wasn't it the main topic of discussion before the election? The mainstream media has been going on and on about fake news for a month. If they genuinely believe that there was a lot of fake news which was crucial to the election outcome, they should have paid more attention and given more coverage to it. Instead they started covering it after the election.
It seems like the fake news is just an excuse for the election loss. The Dems ran a bad candidate who had so much history of being disliked by the electorate and had so much history of corruption, untrustworthiness and being in the pocket of corporate interests and lobbyists. She had the email case and was under investigation. They still ran her and sabotaged a genuinely well liked candidate in Sanders.
Now after the election, the Dems still refuse to recognise the reason for their loss. They, along with the mainstream media, have made the issue of "fake news" the main reason for their loss. Not their horrible candidate, not the fact that they didn't run Bernie Sanders, not the reason of the DNC leaks, not the email scandal, not the paid speeches by their candidate, not Clinton's failure to convey a clear message to the middle and working class, not her vague campaign slogans like "I'm with her" and "Stronger together".
