The Globe and Mail reports in its Thursday, Feb. 26, edition that in the past two weeks, both the U.S. Congress and Supreme Court have strongly opposed tariffs on Canada. The Globe's guest columnist Wolfgang Alschner writes that the Supreme Court ruled that the International Emergency Economic Powers Act tariffs were illegal, while the House voted to end the economic emergency that justified the fentanyl tariffs. These actions reflect a reassertion of authority by the U.S. judicial and legislative branches over the executive. The mood swing is not limited to U.S. institutions. Americans have soured on the tariffs, too. Recent research by the Federal Reserve Bank of New York shows that about 90 per cent of tariff costs are borne by U.S. companies and consumers. A new poll by the Council on Foreign Relations found more than 65 per cent of about 2,200 respondents across party lines said tariffs had made everyday items less affordable. Ahead of the midterms, the political capital for President Donald Trump's tariff agenda is dwindling. Some commentators argue that we are past the "peak." Mr. Trump is now playing a weakened hand. The era of late-night, tariff-threats-by-X is largely over.
