Like many in Virginia, Minn., Jim Pechonick works at an iron ore mine and was raised a Democrat.
Then came Donald Trump with promises to restore the greatness of American steel.
“The only time in my life I’ve ever been out of a job was under Obama,” said Mr. Pechonick, 51 years old, recalling a stretch in 2009-10 when the mine closed due to the poor economy.
In 2016, he joined a sizable number of union workers, particularly white men, who voted for Mr. Trump.
“Somebody needed to shake up the country,” he said.
