Well, maybe it's "Conservatism" that's the problem then, as currently formulated. The Free-trade cult, this obsession with passing trade bills like TPP, open borders, cheap labor, etc., all of these things are utterly fatal to the country. They only benefit big corporations and the elite, but they destroy the country utterly.
We cannot survive any more of this "Conservatism." It must be destroyed.
I don't like Trump at all and am more of a free trader ( I think you compete by cutting taxes, cutting regulation, etc), but you have, I think, made a very important point that is often being overlooked. The fight isn't just over who is more conservative than who on some scale that we use to measure modern day "conservatives", we are now really fighting over what it means to be conservative - and quite frankly, some of those "populist" ideas that Trump and those that agree with him support have a lot more in common with what unions and the left would support. It is possible we are seeing a realignment, or at least a fight over the issue, of what it means to be conservative.
Cheers.
