Who is to blame.

[Faith No More]

I would say that the flood of fake news(I saw one report that claimed that 38% of Republican news pieces were fake) and Russia's meddling fit somewhere in the blame department, too.

The flood of “fake news” this election season got support from a sophisticated Russian propaganda campaign that created and spread misleading articles online with the goal of punishing Democrat Hillary Clinton, helping Republican Donald Trump and undermining faith in American democracy, say independent researchers who tracked the operation.

Russia’s increasingly sophisticated propaganda machinery — including thousands of botnets, teams of paid human “trolls,” and networks of websites and social-media accounts — echoed and amplified right-wing sites across the Internet as they portrayed Clinton as a criminal hiding potentially fatal health problems and preparing to hand control of the nation to a shadowy cabal of global financiers. The effort also sought to heighten the appearance of international tensions and promote fear of looming hostilities with nuclear-armed Russia.
