MILWAUKEE — Four barbers and a firefighter were pondering their future under a Trump presidency at the Upper Cutz barbershop last week. “We got to figure this out,” said Cedric Fleming, one of the barbers. “We got a gangster in the chair now,” he said, referring to President-elect Donald J. Trump. They admitted that they could not complain too much: Only two of them had voted. But there were no regrets. “I don’t feel bad,” Mr. Fleming said, trimming a mustache. “Milwaukee is tired. Both of them were terrible. They never do anything for us anyway.”
