The debate featured a much different dynamic than viewers saw between President Joe Biden and Trump in June.

Here are some of the biggest zingers of the night:

Trump: ‘I’m gonna send her a MAGA hat’

Trump seized on allegations of Harris flip-flopping on her stances from 2020, saying that she was increasingly adopting his stances.

“Everything that she believed three years ago and four years ago is out the window. She’s going to my philosophy now. In fact, I was going to send her a MAGA hat,” Trump said. “She’s gone to my philosophy. But if she ever got elected, she’d change it, and it will be the end of our country.”

“She’s a Marxist. Everybody knows she’s a Marxist. Her father is a Marxist, professor in economics, and he taught her well,” he claimed.

Harris: ‘They’re laughing at you’

Harris attempted to attack Trump’s foreign policy record by questioning his prestige on the international stage.

“I have traveled the world as vice president of the United States, and world leaders are laughing at Donald Trump,” she said. “I have talked with military leaders, some of whom worked with you, and they say you’re a disgrace.”

Harris used the alleged remarks as evidence that Trump isn’t fit to be president.

“And when you then talk in this way in a presidential debate and deny what over and over again are court cases you have lost because you did, in fact, lose that election,” she continued, referencing 2020. “It leads one to believe that perhaps we do not have, in the candidate to my right, the temperament or the ability to not be confused about the fact that’s deeply troubling, and the American people deserve better.”

Trump: ‘Run, Spot, Run’

Responding to Harris’s allegation that prominent economists had denounced Trump’s economic plan, he invoked an interesting comparison to attack her supposed lack of a plan.

“Just to finish off, she doesn’t have a plan. She copied Biden’s plan, and it’s, like, four sentences, like, ‘Run, Spot, Run,’” he said. “Four sentences that are just, oh, we’ll try and lower taxes. She doesn’t have a plan. Her plan, she doesn’t have a plan.”

Harris: ‘Exhaustion and boredom’

Harris went openly off-script, disregarding the moderator’s question to deliver a statement hitting at a major source of Trump’s pride: his rallies.

“And I’m going to actually do something really unusual, and I’m going to invite you to attend one of Donald Trump’s rallies because it’s a really interesting thing to watch,” she said. “You will see, during the course of his rallies, he talks about fictional characters like Hannibal Lecter. He will talk about how windmills cause cancer. And what you will also notice is that people start leaving his rallies early out of exhaustion and boredom. And I will tell you, the one thing you will not hear him talk about is you. You will not hear him talk about your needs and your needs and your desires.”

Trump showed offense at the remarks, saying that he has had the biggest rallies ever.

Trump: ‘I’m talking now’

In a surprise move, Trump flipped one of Harris’s most memorable moves from her 2020 vice presidential debate on him, chastizing her for interrupting him after she could be heard saying, “That’s not true” over a comment about defunding the police.

“Wait a minute, I’m talking now. You don’t mind, please. Sound familiar?” Trump quipped.

Harris’s iconic moment in 2020 came during the vice presidential debate against former Vice President Mike Pence, in which she said, “I’m speaking.”

Harris: ‘I am not Joe Biden, and I am certainly not Donald Trump’

After Trump criticized the Biden administration, Harris sought to distance herself from Biden.

“Clearly I am not Joe Biden, and I am certainly not Donald Trump,” she said. “And what I do offer is a new generation of leadership for our country, one who believes in what is possible, one who brings a sense of optimism about what we can do instead of always disparaging the American people.”

Trump: ‘Wake him up at 4 o’clock in the afternoon’

Trump took aim at Biden and Harris, saying they must take immediate action to solve the border crisis, alleging ineptitude on the part of Biden in the process.

“Go down to Washington, D.C., and let her sign a bill to close up the border because they have the right to do it. They don’t need bills,” Trump argued. “They have the right to do, the president of the United States, you’ll get them out of bed. You’ll wake them up at 4 o’clock in the afternoon. You say, ‘Come on, come on down to the office. Let’s sign a bill.’ If he signed that, the border is closed.”

Harris: ‘A dictator who would eat you for lunch’

Attacking Trump’s record on Russia and Ukraine, Harris attempted to appeal to Polish Americans living in Pennsylvania by connecting him with Putin.

“Understand why the European allies and our NATO allies are so thankful that you are no longer president and that we understand the importance of the greatest military alliance the world has ever known, which is NATO, and what we have done to preserve the ability of Zelensky and the Ukrainians to fight for their independence,” Harris said.

“Otherwise, Putin would be sitting in Kyiv with his eyes on the rest of Europe, starting with Poland,” she said. “And why don’t you tell the 800,000 Polish Americans right here in Pennsylvania how quickly you would give up for the sake of favor and what you think is a friendship with what is known to be a dictator who would eat you for lunch.”

Trump countered by arguing that Putin would still be in Moscow if he were president because the war wouldn’t have begun.
