Jeremy Ladd, a Lordstown plant worker now taking classes to get into nursing school, said that most workers were still coming to terms with what had happened, and that for many, the politics were an open question whose answer would unfold over time.

“People are trying to make sense of this politically,” he said. “It’s like a free radical bouncing around.”

Shawn Wodogaza, a Lordstown plant worker who voted for Mr. Trump reluctantly, said he felt politically lost now.

“I don’t know where to go,” he said. “It seems like no matter what he does or tries to do, it doesn’t work out,” he said of the president. “Well, now what? What the heck do we do? Do we go back to beating our heads against the wall? Or do we try something different?”
