Just calm down, fercryinoutloud.

A number of US states count Canada as their biggest trading partner. Source: http://www.businessinsider.com/state-and-country-trade-maps-2015-7

Most of those states are led by Republicans.

The Repub-led Congress is highly unlikely to do anything to damage the economies of those states. (Quick caveat: they went full-court-press on supply-side economics in Kansas and the result, entirely predictable, was the near-collapse of the Kansas economy. Supply-side economics just doesn't work, that's already been proven. But that's a digression from the trade discussion.)

So all this caterwauling and near-panic is for nothing. Trade will continue in spite of Trump.
