Former president Donald Trump has long inhabited a bizarre world of his own creation. He rewrites history — or makes it up entirely — to aggrandize himself, denigrate others and spread the basest of lies.

It keeps getting worse.

Since Tuesday’s debate with Vice President Kamala Harris, he’s spiraled ever deeper into conspiracy theories, falsehoods and grievances. He insists he is not a loser. He never lost the 2020 election, he says falsely, and he certainly didn’t lose that debate in Philadelphia. He claims victory in an event in which he spent 90 minutes chasing Harris’s barbs down every possible rabbit hole. He rarely managed to get off the defensive long enough to make a case against her — and when he did, he was barely coherent.

Trump can’t accept the widely held verdict that Harris outdid him, just like he couldn’t accept that President Joe Biden defeated him four years ago. On Friday night, during a rally in Las Vegas that was replete with baseless claims about a variety of topics, he spun up the tale that Harris was receiving the questions during the debate. Elevating a conspiracy theory that popped up on social media, he falsely claimed she had hearing devices in her earrings, that she was being coached on what to say in real time. He did it in classic Trump style, citing unspecified hearsay as proof.

“I hear she got the questions, and I also heard she had something in her ear,” he said. ABC News, which hosted the debate, denied these false claims, but Trump cares little for the truth. He prefers to spread lies to excuse his own poor performance and to stir up his supporters to think the game was somehow rigged. All that does is further divide the country.

He used a similar technique during the debate, notably about immigration. That night he repeated a claim that had spread on social media that Haitian migrants in Springfield, Ohio, were eating the pets of local residents. “In Springfield, they’re eating the dogs, the people that came in. They’re eating the cats,” he said.

When David Muir, one of the two ABC moderators, pointed out that the city manager in Springfield had told the network there were “no credible reports of specific claims of pets being harmed, injured or abused by individuals within the immigrant community,” Trump replied, “Well, I’ve seen people on television.”

As Muir tried to interject, Trump continued. “The people on television saying their dog was eaten by the people that went there,” he said. Muir responded, “I’m not taking this from television. I’m taking it from the city manager.”

Trump tried again, saying, “But, the people on television saying their dog was eaten by the people that went there.” Muir countered once more. “Again, the Springfield city manager says there is no evidence of that,” he said. “We’ll find out,” an unrepentant Trump said.

In the past few years, Springfield has experienced a large influx of Haitian immigrants, who are in the United States legally. They have filled jobs in local businesses but they also have put a strain on the city’s services and caused an uproar among some local citizens. Trump and running mate Sen. JD Vance (R-Ohio), seeking to highlight the issue of immigration in the campaign, helped put the town in the spotlight after an 11-year-old boy was killed in a traffic accident caused by a Haitian migrant.

Nathan Clark, the boy’s father recently denounced those who have invoked the death of his son to score political points, calling it “reprehensible.” “To clear the air,” he said last week, “my son Aiden Clark was not murdered. He was accidentally killed by an immigrant from Haiti.” He criticized Trump, Vance and other politicians for using the tragedy to advance their own interests. “They have spoken my son’s name and use his death for political gain,” he said. “This needs to stop now.”

The repeated false claims about the Haitian community have brought threats to the city. On Friday, two elementary schools in Springfield were evacuated because of bomb threats and a middle school closed. It was the second day in a row that schools were closed due to such threats. The Columbus Dispatch reported that one of the threats included the same debunked claims about the migrant community that have circulated on social media.

Trump continues to fuel anti-immigrant outrage. He has previously said that if elected he would order the deportation of all undocumented immigrants living in the United States, a proposal judged by experts as both impractical and legally questionable. During a Friday news conference with reporters in California, Trump said, “We’re going to have the largest deportation in the history of our country. And we’re going to start with Springfield and Aurora, [Colorado].”

Aurora is another city Trump cites as being destroyed by illegal migration, saying that it has been overrun by Venezuelan gangs. Aurora Mayor Mike Coffman, a former Republican U.S. House member, said last week that such claims are “grossly exaggerated,” that the problem is limited to specific housing properties and is being dealt with by law enforcement.

That Trump has lost focus on the messages his campaign wants to highlight has beenevident for weeks. There are issues that could put Harris on the defensive, if he were capable of a sustained and effective message based on facts and not falsehoods. He’s proving that he isn’t able to do that.

Most polls show that voters believe he is better able to handle the economy and inflation, issues at the top of voters’ lists of concerns. He has an advantage on immigration. Beyond that, Harris is still trying to fill out her profile for voters. In a Friday interview with Brian Taff of WPVI-TV in Philadelphia, she offered mostly general answers to some specific questions about how she would lower prices and where she differs with Biden.

In the debate, Trump tried repeatedly to put immigration front and center, but he was ineffective, in large part because of exaggerations or, as with the Springfield example, outright lies. Many Republicans who support Trump for president fear he is neither talking about what matters most to voters nor heeding the counsel of his campaign’s senior advisers.

Meanwhile, the question of who has his ear has come to the fore. Laura Loomer is an attention-seeking purveyor of racist and homophobic comments and a spreader of conspiracy theories. Recently she posted on X that if Harris, who is Black and Indian American, is elected, the White House will “smell like curry & White House speeches will be facilitated via a call center.”

Last week, Loomer accompanied Trump to the debate in Philadelphia and joined him the next day at ceremonies commemorating the 23rd anniversary of the Sept. 11, 2001, terrorist attacks. A year ago, she had posted on X that those attacks were “an inside job,” a conspiracy theory for which there is no evidence.

Her presence at Trump’s side has alarmed many Republicans. Sen. Thom Tillis (R-N.C.) recently posted on X: “Laura Loomer is a crazy conspiracy theorist who regularly utters disgusting garbage intended to divide Republicans. A DNC plant couldn’t do a better job than she is doing to hurt President Trump’s chances of winning reelection. Enough.”

Sen. Lindsey Graham (R-S.C.) told a reporter for HuffPost that her history “is just really toxic.” Even Rep. Marjorie Taylor Greene (R-Ga.), a committed acolyte of Trump and his Make America Great Again movement, and herself a purveyor of conspiracy theories and falsehoods, called Loomer’s comment about Harris “appalling and extremely racist,” adding, “This type of behavior should not be tolerated ever.”

Trump,who has praised Loomer over the years, on Friday tried to duck from the criticism about her. He first claimed that he didn’t really know what she has said. Later he posted on Truth Social that he disagrees with the statements she’s made, a classic dodge on his part.

He went on to suggest that she is justified because she is “tired of watching the Radical Left Marxists and Fascists violently attack and smear me.” Apparently, no one can be too extreme if they support him — or at least they can be forgiven.

This has been Trump’s pattern from the time he first became a candidate nine years ago. If anything, he has becomeeven less disciplined and more conspiratorial than he was back then. Few people likely to vote this fall do not already have an opinion about him, pro or con. Because the country is so closely divided and questions about Harris exist, he remains in a position to possibly win the election.
