I always ranked the 'renegotiating NAFTA' statements one of the more likely to be hot air from a serial liar. It counts as an easy thing to say when trying to get votes, but is connected to vast amounts of very problematic reality.

A memo on this after the election is concerning, but I still have doubts. There are many people in the US government who understand the complexities of trade, including civil servants, lobbyists and members of Congress, who won't let the US damage the interests of many of its own successful industries.
