Does not surprise me because Trump is a populist, not a conservative. And after 25 years of outrageous crony nonsense, most people out there have lost faith in the free market.
Any candidate who toes the traditional Conservative line on economics is going to fare badly in this cycle IMHO.
There is also the fact that neocons have successfully stolen the definition of conservative. They are not conservative. Their policies have proven to be radical and ruinous and are rejected by the diminishing middle class.
Once again a Trumpocrat confirms he agrees with Bernie Sanders on economics more than he does with Ted Cruz.
