Facing deteriorating polling numbers and an unfavourable personal rating, Ms. Clark decided to out Trump Trump by threatening the shipment of non-metallurgical coal (including coal shipped from the US and from Alberta) to BC ports for export. 

Such blustering at this time works at cross purposes to Federal negotiations with the US and Mexico over a wide range of trade issues. Implementation by BC would violate several Canadian foreign trade deals and would illegally interfere with interprovincial trade and commerce. BC lacks jurisdiction to implement in any case.  

However, all this is outweighed for Ms. Clark because there's a tight election to be won and populist bombast just might tip the balance to the BC Liberals (polling since the bombast, in fact, is more promising for the Liberals).

BC deserves better.
