Who are the voters behind Trump’s higher approval rating?

Justin Penn, a Pittsburgh voter who calls himself politically independent, favored Joseph R. Biden Jr. in a matchup with President Trump until recently. But the president’s performance during the coronavirus outbreak has Mr. Penn reconsidering.

“I think he’s handled it pretty well,” he said of the president, whose daily White House appearances Mr. Penn catches on Facebook after returning from his job as a bank security guard. “I think he’s tried to keep people calm,” he said. “I know some people don’t think he’s taking it seriously, but I think he’s doing the best with the information he had.”

Although Mr. Penn, 40, said he did not vote for Mr. Trump, his opinion of the president has improved recently and he very well might back him for a second term.
