No border tax or tariff, my guess is the Democrats use their populist arm to expose him as someone who doesn't keep his promises and he becomes a one term president. Even Chuck Schumer was going after him hard after the State of the Union address, challenging Trump regarding all his promises about jobs, saying "he is all talk, where is the action"?
It's all about jobs, protecting jobs, equalizing the abuse of foreign governments who exploit American workers and standing up for the downtrodden. He could succeed in every other facet, if he fails in jobs and protecting American workers, there is no chance for re-election. That's my take on this, every other issue is far down the list of important to those being exploited by China, Mexico and Canada.
