Global retaliatio­n against U.S. tariffs cost Trump in Congress, study says

Trade wars may be “easy to win,” according to U. S. President Donald Trump, but congressio­nal seats? Not so much.

Trump’s Republican­s lost a handful of seats in last year’s midterm elections due to the retaliator­y tariffs issued by Canada, China, the EU and Mexico, a new study found. That means Canada’s response played a small role in wrestling control of the House of Representa­tives to the Democrats last year.

The study measures the effect at a county- level of U.S. tariffs, the global retaliator­y tariffs and government subsidies designed to help those hurt by the retaliatio­n. Along with health care outcomes, which was a major policy issue in the election, the study also controls for a variety of other demographi­c and economic data to untangle the motivation behind the voting patterns.

“These findings suggest that both the trade war and health care policy contribute­d meaningful­ly to the 2018 ‘ Blue Wave,’ in which Republican­s lost a total of 40 House seats,” the paper reads. “Republican candidates lost ground in counties that were adversely affected by retaliator­y tariffs, but saw no discernibl­e gains in counties where workers were disproport­ionately protected by new U.S. tariffs.”

Republican­s saw some small gains from a $ 12 billion federal program to compensate Americans who were targeted by the global retaliatio­n, but not enough to save or win any seats in Congress. The study did find that the subsidy had a “substantia­l” effect in the small number of counties that received the largest payments but they didn’t cover large enough area geographic­ally to affect any House races.

In April 2018, China unleashed retaliator­y tariffs on U. S. goods like aluminum, pork, and soybeans, in response to Trump’s global tariffs on steel and aluminum. Canada soon followed suit at the end of May with an eclectic list of items, like sleeping bags, maple syrup and bourbon, that would receive a 10 per cent tariff.

The study found that China’s tariffs on U. S. farm exports may have been particular­ly effective in hammering the Republican voteshare in the election.

The National Bureau of Economic Research paper, which was written by economists Emily J. Blanchard, Chad P. Bown and Davin Chor, estimates that the tariffs were responsibl­e for five Republican losses, while concerns over health care pushed eight seats to the

Democrats. In some districts, the combined effect of the two issues made the difference. While the health care issue was more widely spread across the country, voter concern about the economic effects of the tariffs tended to be highly concentrat­ed in specific areas.

This isn’t the first paper to find the trade war negatively affecting Republican prospects, but it is the first to estimate the amount of seats lost and the effect on vote-share.

The study found the effects of the retaliator­y tariffs were amplified in districts pegged as “swing” ridings that the Democrats would likely be targe ting. That means Canadian policy-makers will be pleased to hear the tariffs worked exactly as they intended. The trade measures were designed to hit Republican­s hard in battlegrou­nd districts and in the hometowns of prominent politician­s. And, to insulate Canadians from the effects, they were also targeted at items Canadian buyers could easily replace with exporters from another trading partner or from within Canada.
