Former President Joseph R. Biden Jr.’s aides did not want him to speak with me.
Yet when I reached Mr. Biden on his cellphone in late March, he answered and agreed to talk. He broke his silence on his successor to criticize the early weeks of Mr. Trump’s second term. “I don’t see anything he’s done that’s been productive,” the former president said.
When I asked if he had any regrets about dropping out of the presidential race, Mr. Biden said, in a detached tone, “No, not now. I don’t spend a lot of time on regrets.” Then he hung up because he was boarding an Amtrak train.
My brief conversation with Mr. Biden prompted a cascade of concern among his top aides. One screamed at me for calling the former president directly. Others texted furiously, trying to figure out how I had obtained Mr. Biden’s phone number.
Mr. Biden had seemed open to continuing the conversation, but my subsequent calls went straight to voice mail. His automated greeting simply said, “Joe.”
Two days later, that greeting was replaced by a message from Verizon Wireless: “The number you dialed has been changed, disconnected or is no longer in service.”
The swift reaction to my call reflects the insularity that became a defining feature of the final stages of Mr. Biden’s political career. And in no instance was the protectiveness of his staff, and his failure to connect with outside voices, more pronounced than in the period after his disastrous debate performance 13 months ago. At the most perilous moment of his presidency, with his prospects for re-election teetering amid growing concerns about his age and mental acuity, Mr. Biden was all but impossible for anyone outside his tight inner circle to reach.
Instead of confronting the president with the bad news, his aides limited access to him, making it difficult for even some of his longtime friends and allies in Congress to reach him, including Senator Chris Coons, a Democrat from Delaware and a close ally.
Mr. Biden’s aides never had him meet with his campaign’s pollsters. Instead, they often presented overly optimistic outlooks of the political landscape, alarming members of the campaign staff, who looked for ways to bypass his longtime advisers Steve Ricchetti and Mike Donilon to get information to the president. For the most part, they failed to reach him.
Mr. Biden had a team of campaign pollsters who were prepared to tell him the truth about the numbers, but they never got the opportunity. They were told they should present to his closest advisers — not to the president himself.
The pollsters tried to be as polite as possible, but their conclusion was damning: Their research found that Mr. Biden was just not able to persuade voters that he was up for the job. The president had no path to victory.
Two days after the presentation, Geoff Garin, one of the pollsters, checked in with Mr. Ricchetti. Mr. Ricchetti lit into him and said the presentation was out of line. It was not their job to tell them there was no path to victory. The pollsters, Mr. Ricchetti said, were supposed to provide the path to win.
When former Speaker Nancy Pelosi, Democrat of California, met privately with Mr. Biden in the White House for a crisis meeting that July, she grew frustrated by his insistence that the polling showed no real change since the debate. Was he not seeing the numbers she was seeing?
At one point, Mr. Biden asked an aide to put Mr. Donilon on the phone because the president did not believe Ms. Pelosi. She was adamant the polls showed Mr. Biden would lose to Mr. Trump.
Mr. Donilon got on the line and said he disagreed.
In the months since Mr. Trump took office, many Democrats have expressed regret that they did not call for Mr. Biden to drop out sooner — or push him to not run for re-election at all. The former president’s closest aides maintain a different view. He should have never given into pressure and abandoned his re-election campaign, they argue.
“It was an act of insanity by the Democratic leadership,” Mr. Donilon said in an interview for this book. “Tell me why you walked away from a guy with 81 million votes.”
He added: “The only one who has run ahead among seniors. A native of Pennsylvania. Why do that?”
