THE BURNED OVER DISTRICT

During the campaign Donald Trump, among his many promises, said he would stop jobs from leaving the US and get them to return. Now that the election is over, the Trumpoons are expecting a rapid response and results on these promises.

Carrier’s decision to move the factory to Monterrey, Mexico, will eliminate 1,400 jobs by 2019. Mr. Trump quickly made the factory Exhibit A in his argument against the trade policies of Republicans and Democrats alike.

He cited Carrier again and again on the campaign trail, threatening to phone executives at the company and its parent, United Technologies, and to hit them with 35 percent tariffs on any furnaces and air-conditioners they imported from Mexico. To the cheers of his supporters, he predicted at rallies that Carrier would call him up as president and say, “Sir, we’ve decided to stay in the United States.”

Now his supporters expect action. “If he doesn’t pass that tariff, I will vote the other way next time,” warned Nicole Hargrove, who has worked at Carrier for a decade and a half and is not certain what she will do if and when her job goes to Mexico.

Carrier isn’t changing its plans. On Friday in a written statement, the company said, “We are making every effort to ease the transition for our Carrier colleagues in Indiana.” The company pointed out that it will finance four-year retraining and educational programs for employees and provide financial help.

For Mr. Trump, now comes the hard part. In interviews in recent days and in March, Trump voters here made clear that if he does not follow through on his promises, they are prepared to turn on him, just as they are seemingly punishing Democrats today for not delivering the hope and change voters sought from President Obama after he won as an outsider in 2008.

And while Mr. Roell is a conservative, Mr. Trump’s tough talk about Carrier, the economy and the future of American manufacturing jobs also appealed to moderates like Darrell Presley, a steelworker in rural Crawfordsville, Ind., who voted for Mr. Obama in 2008. “He was for change, and said he would take care of the middle class, but he didn’t live up to those expectations,” Mr. Presley said. “I feel like the American people are at the point where they’ve had it, and this was the last chance.”

Last Tuesday, blue-collar workers across the industrial heartland hearkened to Mr. Trump’s call, putting states never thought to be in serious play, like Wisconsin and Michigan, in his win column.

As president, however, Mr. Trump will face a tough balance. Tariffs and trade wars stand to hurt American workers who make products that are exported to Mexico or China. Few voters will be happy paying more for imported goods.

Few voters have a chance of influencing Donny and most of them have already decided to ship their production overseas to make money. The main question is how long will it take these Trump voters to realize they voted away their lives and futures for nothing.
