Michael Smith is not used to stretching a paycheck. As recently as March 2015, the 42-year-old was earning nearly $100,000 a year as a district manager on oil fields for company based in Union City, Pa. Then oil prices dropped, and his company laid him off.
Smith, a father of four boys, now makes $12 an hour as an apprentice electrician. He is not a die-hard disciple, but voted for Donald Trump because he's desperate for something new.
"Do I think Donald Trump is what this country needs and do I think he will make it great again? No," Smith said. "Do I think he is a step in the right direction? Absolutely."
It was not poor Americans who made the difference in this election; it was people like Smith. Trump soared among white voters who earn decent wages, but have seen their pay decline and jobs in their industries disappear over the past 15 years.
Some of those workers say they were responding in part to Trump's repeated bashing of trade, and at the same time perceived Hillary Clinton as a poster child for the free-trade deals that her husband signed and President Obama tried to push through Congress.
"A lot of our members equated NAFTA to Hillary and Bill Clinton," said Donnie Blatt, a coordinator with the United Steelworkers union in Ohio. "A lot of our members felt like they hated Hillary Clinton, they believed she caused the loss of all their jobs."
But it will be almost impossible for Trump to fulfill his promise to bring back most of the assembly line gigs lost to globalization, economists say. The U.S. has moved toward advanced manufacturing, which employs highly educated people, and plants that once required manual labor are now manned by robots that work faster than people and cost less. U.S. factories are producing more than ever, with far fewer employees.
"The Democrats have no credibility with these people, and the trade issue brings it out more than anything," said Dean Baker, the co-director of the left-leaning Center for Economic and Policy Research. "Trump is making these promises, but they aren't realistic. It isn't like he has a plan to bring the jobs back, but he was out there saying it."
It's not surprising that trade issues resonated with some voters in vast swaths of the Midwest and Southeast.
Since 2000, American manufacturers wiped 5 million people off their payrolls, according to the Bureau of Labor Statistics. Millions of those jobs went to China or Mexico, research suggests.
For context, it took more than three decades for 560,000 mining jobs to disappear, after reaching a peak of 1.2 million the early 1980s.
The shock of losing so many middle-class jobs so quickly hit hardest in the Rust Belt states, which were crucial to Trump's victory. Ohio, Michigan, and Pennsylvania had among the steepest cuts in assembly line jobs across the country since 2000.
California cut the most manufacturing jobs of any state from 2000 to 2015, partly because its workforce is so huge. More than 576,000 Californians lost their jobs in factories over that period.
But the biggest losers after California were Ohio, Michigan, North Carolina and Pennsylvania, which hemorrhaged a combined 1.2 million manufacturing jobs. That means that about a quarter of the total manufacturing job loss in the country since 2000 occurred in those four swing states.
Ohio and Pennsylvania voted for a Republican for the first time since at least 2004. Michigan hasn't been called for Trump, but he is leading there.
The counties in those states where Clinton lost the largest number of voters compared with Obama in 2012 were also the counties that lost particularly large numbers of manufacturing jobs over the last 15 years, according to Bureau of Labor Statistics data.
How much of the shift took place because of trade is hard to tell: The job losses mostly took place during the first decade of this century, but the states did not flip to vote for a Republican until this year. And many other issues were in play, including tensions over immigration, race and the presence of a woman on the Democratic ticket.
Still, trade and its impact on manufacturing jobs almost certainly played a role in boosting Trump's prospects in the nation's industrial belt.
"The real ones who are hurt [by trade] are centered, not coincidentally, in the swing states in this election," said Peter Navarro, an economist from UC Irvine who has been a powerful voice on Trump's economic advisory board.
"You go around the rim of the Midwest…those are the key states that have been ground zero of this problem," Navarro said.
These workers were not necessarily scraping by — the average American with a factory gig made around $64,000 in 2015, BLS data show. But in Ohio, Michigan and Pennsylvania, pay for manufacturing employees has declined or remained relatively flat since 2000, after adjusting for inflation, even as it inched up in the country overall.
Automation has been steadily decimating assembly line jobs, and as new plants come back to the U.S. they are increasingly staffed by robots.
But trade has also damaged American factories, something workers noticed long before academics measured it.
"Until a few years ago most economists were convinced that international trade had only very minor implications for labor markets," said David Dorn, an economist who specializes in U.S.-China trade.
"Academics and policymakers underestimate the negative side effects of globalization by quite a bit," he said.
China alone could have knocked out up to 2.4 million jobs in the U.S. from 1999 to 2011, according to a recent study that Dorn co-wrote.
That economic shock made people want change.
