Did he not campaign on "Drain the Swamp?" We will see...Trump didn't win. Hillary lost. She did not have a coherent message. Her entire campaign was "I'm better than Trump."
At least Trump had a message, "Make America Great Again" and he stuck to it. There were few specifics on how he intended to accomplish that goal, but at least he had a goal that was articulable, which is more than Hillary had.
Also Hillary raised over $687 million dollars to Trumps $306 million. Clinton's funding came mostly from corporate giants and people like George Soros. Trump's funding came mostly from small individual donors, raised over the internet.
This election was a grass roots movement from beginning to end. It was the electorate's way of saying "enough is enough" to Washington DC politics as usual.
Now soon-to-be President Trump has to figure out a way to avoid becoming part of "Washington DC politics as usual." And that is going to be very hard to do.
