In the days that followed the election, I was able to stomach some of the right wing media. I wanted to see the heads exploding. So I turned on Bill O'Reilly. He said something I thought was very insightful, and with a minor change I believe I can agree with him:

The white establishment is now the minority. And the voters, many of them, feel that the economic system is stacked against them and they want stuff.
I have seen much made of the "stuff" argument on both sides and I would agree with Bill if he had said "different" stuff. For sure the Koch Bros et al would have expected "stuff" for their "investment" of billions of dollars of Super Pac money, but different "stuff" than what the middle class wants. (Other diarists have pointed this out.)

But I think the larger point that is missed is that voters "feel that the economic system is stacked against them".

He was saying this with derision but I felt it hit the nail on the head. People have come to realize that this economy favors the wealthy over the middle class.
