In this April 13, 2017, file photo, a young calf looks out from its pen while U.S. Sen. Tammy Baldwin, D-Wis., met with leaders from the Professional Dairy Producers of Wisconsin to discuss Canadian trade barriers and the impact it has had on the dairy industry at Five Star Dairy Farm in Elk Mound, Wis. President Donald Trump has a point when he lambastes Canada for protecting its dairy farmers with hefty tariffs.
But the United States is hardly innocent when it comes to farm protectionism. And the very real difficulties that U.S. dairy farmers face can't all be blamed on America's neighbor to the north. And in fact, despite Canada's tariff, the U.S. runs a surplus in dairy trade with its northern neighbor. (Marisa Wojcik/The Eau Claire Leader-Telegram via AP, File)
