Let me get this out of the way first: I'm irritated at all the media people repeating that "nobody" saw Donald Trump's "upset" win coming. I saw it coming a million miles away. Here, let me touch myself ... am I someone? Yep, I still exist. Is it really possible that I'm the only pundit in America who grew up in the Rust Belt and goes home to visit?
Of course the corporate media morons didn't see this coming. They didn't see looming disaster in the invasion of Iraq. During the primaries, they ignored the polls that proved Bernie Sanders was a better candidate than Hillary Clinton against Donald Trump. It certainly never occurred to the corporate media morons that reducing tens of millions of middle-class workers to poverty, in order to line the pockets of globalization-besotted elites, might turn them into tens of millions of angry voters.
The bigger the news outlet where these mainstream political hacks work, the more money they make, the more journalism prizes they win, the less these idiots see anything coming (c.f., Ross Douthat, New York Times, March 8, 2016: "Donald Trump will not be the Republican nominee").
