Pollster Frank Luntz cautioned on Monday that a potential presidential matchup between former President Donald Trump and Vice President Kamala Harris could lead to a break-up of the country.

On Sunday, President Joe Biden decided to drop out of the election and support Harris after receiving requests from his party’s allies to withdraw from the race after his disastrous debate with Trump in June. Luntz told  “CNN News Central” that Trump’s uncontrolled language and Harris’ readiness to engage in a fight could result in a campaign that is exceptionally nasty.

“Trump has no hesitation, he has no filter, he has no self-censor. And she will fight him attack for attack, insult for insult and I‘m afraid of [the] negativity of this campaign,” Luntz said. “Trump was unable to control himself. The speech that he wrote for last Thursday night was very powerful and very unifying. But that‘s not what he delivered. He wrote a 45-minute speech. He ad-libbed another 45 minutes and it’s all the negativity that voters don‘t like. She’s got more discipline, she’s better able to stick to the teleprompter and stick to the message.”

“But I’m really concerned about whatever debate they have, because there will be no holds barred, no boundaries and we’re already at a breaking point democratically,” he continued. “And I’m just afraid that this could push the country over the edge.”

Democratic National Committee member Elaine Kamarck mentioned on Monday that there’s “no time” left before the party’s convention for a different candidate to emerge as the nominee instead of Harris. She further claimed that Harris enjoys a considerable edge over Biden’s delegates, given her probable connections established while serving as vice president.

“I think we have run out of time here,” Kamarck said. “One of the reasons the party is coalescing so quickly behind Kamala Harris is frankly, we have no time.”

After Biden withdrew from the race on Sunday, a Trump-aligned PAC, MAGA Inc, wasted no time and launched an advertisement targeting Harris less than two hours later.

“Kamala was in on it. She covered up Joe’s obvious mental decline,” a narrator says in the ad. “Kamala knew Joe couldn’t do the job, so she did it. Look what she got done: a border invasion, runaway inflation, the American Dream dead.”
