Canada’s foreign minister, Chrystia Freeland, spent most of her time on visits to the U.S. lobbying governors and congressmen rather than talking seriously to our trade negotiators. Her boss, Prime Minister Justin Trudeau, even thought it was a good idea to antagonize Trump at his failed G7 summit in June.

Canada must now return, hat in hand, for a deal. If not, Trump will advance the deal with Mexico and leave Canada behind. Today he again vowed to raise car tariffs on Canada if it refuses to revise unfair levies of nearly 300 percent on some American goods, among other unfair practices.

the stress of a campaign can reveal some essential truths, and the picture of Mr. McCain that emerged this year is far from reassuring. To pass his party's tax-cut litmus test, he jettisoned his commitment to balanced budgets. He hasn't come up with a coherent agenda, and at times he has seemed rash and impulsive. And we find no way to square his professed passion for America's national security with his choice of a running mate who, no matter what her other strengths, is not prepared to be commander in chief.

Senator John McCain of Arizona has retreated farther and farther to the fringe of American politics, running a campaign on partisan division, class warfare and even hints of racism. His policies and worldview are mired in the past. His choice of a running mate so evidently unfit for the office was a final act of opportunism and bad judgment that eclipsed the accomplishments of 26 years in Congress.
