For most of the president’s term, Mr. Carr, a 53-year-old real estate lawyer, had been relentlessly attuned to the news cycle and the damage he felt Mr. Trump had done to the country. But ever since Nov. 7, when the election was called for Joseph R. Biden Jr., Mr. Carr has given himself permission to keep the television on mute.

“It’s like a weight has been lifted,” said Mr. Carr, who voted a straight Democratic ticket on Nov. 3, as he did in 2016. “It’s so nice not to be as plugged in.”…

“He’s just a whiny kid who didn’t get his way. I’m not sweating it,” said Blake Lertzman, 39, while taking a smoke break outside his technology repair shop in the Bucks County seat of Doylestown. “Right now it’s all about the virus. I worry about me and my girlfriend and my community.”

As for Mr. Trump’s fervent efforts to overturn the election, “nobody cares,” Mr. Lertzman went on, “unless you’re the kind of person who goes on Newsmax.”
