There is so much nonsense here. He wants a third party that is opposed to populism. In favor of what, letting the experts make our political decisions? A lot of us do not want what David Brooks wants. He represents an elite that has been unwilling to look at the economic desperation of working class people. Yes Trump is gross, but the Democrats helped create him by refusing to deal with reality. They could have nominated Bernie Sanders. During the primaries Sanders was polling better against Trump than Clinton, that pillar of the establishment. 

We are not willing to continue business as usual. You can choose populism of the left or populism of the right.
