If there is one thing we know for sure about Trump, it is that he absolutely loves tariffs, because the system gives him essentially unlimited power to ruin his adversaries and get attention by imposing them to solve bogus “emergencies”. His latest threat to Mexico over illegal immigration is a case in point.
The majority of GOP members of Congress hate his tariffs. They could join with the Democrats to put appropriate limits on his discretion to impose them if they had the nerve. Their fear of him, of course, is far stronger than their devotion to free trade and the national interest, so it won’t happen. Let’s hope they pay the price for it in 2020.
