The framing of the 2016 election is that this is the establishment vs the anti-establishment. Clinton represents Washington DC. Trump represents the masses.
This is bullshit.
There are two establishments at war here. One is the obvious one, the party elites. Clinton is more or less part of that, though not as much as people suppose. She's actually an outsider who's fought her way in. If you doubt this for a second, examine the first Clinton's presidential period of 1991 to 2001 (I'm counting the initial campaigns as much as the being in office), and notice the entire period was a war between the Clintons, a Republican establishment who despised them, and a Democratic establishment who didn't trust them and only rallied around the cause when the Republicans went over the top.
The second is the general group that's had power and had the government direct power in their favor for as long as the US has been in existence, primarily the rich, but with a white, male, protestant secondary base as a group to keep happy.
These are, to some extent, the same groups, but the second group no longer believes that the party elites can be trusted to keep bowing to their whims.
Hence the fact a third rate reality TV star whose business successes are built upon fraud and deceit is suddenly able to reach this level of electoral success. Trump is a prime example of someone government has always worked for, yet he's untainted by DC itself. His character doesn't matter. He's part of the underlying establishment, and not part of the elite, so he's the person they pick.
