Yesterday, Fox News columnist David Marcus published a short piece about the surprises that greeted him on a weekend visit to Calgary. The theme of the piece is: hey, these people are really angry about Trump’s trade war! Marcus half-expected Canada to be preoccupied with the Liberal Party leadership race and the imminent choice of a new prime minister — but all anybody wanted to talk about in the cozy confines of the James Joyce Pub in Calgary were feelings of betrayal and confusion toward the United States. Even the television news (“Imagine a country in which basically every news channel is MSNBC”) was all tariffs, all the time.
