One thing that will result from this is that those harmed by these policies will be more supportive of free trade and is likely to pull the Democrats more in a free trade direction, which is their historical norm.
The pre-New Deal GOP was protectionist, but their motive was the opposite of Trump's. Then, businesses wanted protectionism while the lower classes wanted free trade. Today, businesses want free trade and the working class wants protectionism.
RINO Tom no doubt will say that many pre-New-Deal protectionists would be free traders today and that many pre-New-Deal free traders would be protectionists today.
Well, if their sole motive was to follow in line with the businesses, then yes, they would have switched positions today.
