“There are a lot of things about the 2016 election that nobody saw coming, and one of them is that international trade policy is likely to be a major issue in the presidential campaign. What’s more, the positions of the parties will be the reverse of what you might have expected: Republicans, who claim to stand for free markets, are likely to nominate a crude protectionist, leaving Democrats, with their skepticism about untrammeled markets, as the de facto defenders of relatively open trade.
But this isn’t as peculiar a development as it seems. Rhetorical claims aside, Republicans have long tended in practice to be more protectionist than Democrats. And there’s a reason for that difference. It’s true that globalization puts downward pressure on the wages of many workers — but progressives can offer a variety of responses to that pressure, whereas on the right, protectionism is all they’ve got.”
