Donald J. Trump was in a state of shock: He had just fired his campaign manager and was watching the man discuss his dismissal at length on CNN. The rattled candidate’s advisers and family seized the moment for an intervention.
Joined by his daughter Ivanka and her husband, Jared Kushner, a cluster of Mr. Trump’s confidants pleaded with him to make that day — June 20 — a turning point.
He would have to stick to a teleprompter and end his freestyle digressions and insults, like his repeated attacks on a Hispanic federal judge. Paul Manafort, Mr. Trump’s campaign chairman, and Gov. Chris Christie of New Jersey argued that Mr. Trump had an effective message, if only he would deliver it. For now, the campaign’s polling showed, too many voters described him in two words: “unqualified” and “racist.”
Mr. Trump bowed to his team’s entreaties, according to four people with detailed knowledge of the meeting, who described it on the condition of anonymity. It was time, he agreed, to get on track.
Nearly two months later, the effort to save Mr. Trump from himself has plainly failed. He has repeatedly signaled to his advisers and allies his willingness to change and adapt, but has grown only more volatile and prone to provocation since then, clashing with a Gold Star family, making comments that have been seen as inciting violence and linking his political opponents to terrorism.
Advisers who once hoped a Pygmalion-like transformation would refashion a crudely effective political showman into a plausible American president now increasingly concede that Mr. Trump may be beyond coaching. He has ignored their pleas and counsel as his poll numbers have dropped, boasting to friends about the size of his crowds and maintaining that he can read surveys better than the professionals.
In private, Mr. Trump’s mood is often sullen and erratic, his associates say. He veers from barking at members of his staff to grumbling about how he was better off following his own instincts during the primaries and suggesting he should not have heeded their calls for change.
He broods about his souring relationship with the news media, calling Mr. Manafort several times a day to talk about specific stories. Occasionally, Mr. Trump blows off steam in bursts of boyish exuberance: At the end of a fund-raiser on Long Island last week, he playfully buzzed the crowd twice with his helicopter.
But in interviews with more than 20 Republicans who are close to Mr. Trump or in communication with his campaign, many of whom insisted on anonymity to avoid clashing with him, they described their nominee as exhausted, frustrated and still bewildered by fine points of the political process and why his incendiary approach seems to be sputtering. [...]
People around Mr. Trump and his operation say they are not ready to abandon hope of a turnaround. But he is in a dire predicament, Republicans say, because he is profoundly uncomfortable in the role of a typical general election candidate, disoriented by the crosscurrents he must now navigate and still relying impulsively on a pugilistic formula that guided him to the nomination.
His advisers are still convinced of the basic potency of a sales pitch about economic growth and a shake-up in Washington, and they aspire to compete in as many as 21 states, despite Mr. Trump’s perilous standing in the four states — Florida, Ohio, Pennsylvania and North Carolina — likely to decide the election.[...]
Even before Mr. Trump’s most recent spate of incendiary comments, Republicans who dealt with him after the primaries came away alarmed by his obvious unease as the de facto party leader. After a meeting in late May between Mr. Trump and Karl Rove, the architect of George W. Bush’s presidential victories, Mr. Rove told associates he was stunned by Mr. Trump’s poor grasp of campaign basics, including how to map out a schedule and use data to reach voters.[...]
Mr. Trump’s advisers believe he is nearly out of time to right his campaign. On Tuesday, hours before his explosive comment about “Second Amendment people” taking action if Mrs. Clinton is elected, his brain trust reassembled again at Trump Tower in a reprise of their stern meeting in June.
They again urged Mr. Trump to adjust his tone and comportment. The top pollster, Tony Fabrizio, gave an unvarnished assessment, warning that Mr. Trump’s numbers would only move in one direction, absent a major change.
Mr. Trump, people briefed on the meeting said, digested the advice and responded receptively.
It was time, he agreed, to get on track.
