WASHINGTON — The sound you might have heard after the presidential debate last week in Atlanta was of voters falling between a rock and a hard place.

Apart from the sizable and pumped-up universe of Donald Trump’s supporters, the debate crystalized the worries of many Americans, a portion of President Joe Biden’s supporters among them, that neither man is fit to lead the nation.

Heading into the first debate of the general election campaign, voters had faced a choice between two strikingly unpopular candidates. They then watched as Trump told a stream of falsehoods with sharpness, vigor and conviction, while Biden struggled mightily to land debating points and even to get through many sentences. It added to doubts about the 81-year-old Democratic president’s fitness to be in office for four more years.

Now the options are even more dispiriting for many Democrats, undecided voters and anti-Trump Republicans. More than a few people came away from watching the debate conflicted.

Outside a Whole Foods in downtown Denver, Democrat Matthew Toellner tilted his head sideways Friday, mouth agape, in an imitation of his favored candidate, Biden, who was seen doing that at times on the split screen when Trump was talking Thursday night.

“I’m going to vote for Biden,” said Toellner, 49, leaning against the wood siding of the grocery store. “Actually, I might not.”

A few minutes later, Toellner looked out to the street and rethought again. “I’m going to vote for Biden, I think I’d be a fool not to. But I just hate that I have to.”

His appeal to Biden and Democrats: “Please step down, get somebody electable.”

On a Detroit park bench, Arabia Simeon was left feeling politically homeless after voting Democratic in the past two presidential elections. “It just feels like we’re doomed no matter what,” she said.

Trump’s disregard for the facts suffused his arguments, though he was rarely challenged on the specifics during the debate.

On abortion, for example, one of America’s most divisive issues for generations, the former Republican president claimed there is universal agreement that states should decide on the legality of it. There is ferocious argument about that.

But did that matter?

The public reaction, in dozens of interviews across the country, brought to mind Bill Clinton’s post-presidency assessment of what voters want in fraught times: “When people feel uncertain, they’d rather have someone strong and wrong than weak and right.”

The debate unsettled Simeon just as it did Toellner.

The 27-year-old owner of a Detroit startup went into debate night weighing Biden against an independent candidate, the most prominent of whom is long shot Robert F. Kennedy Jr.

Now she’s leaning against Biden.

“I think it just kind of validated the feeling that I was having that this election is going to be extremely hectic, and it’s no longer the conversation of the lesser of two evils for me,” she said.

Simeon said that as a Black and queer person, “It’s really disheartening to know that no matter how far we come as a country, we’re still going to factory reset when it comes to president and have to make a choice between two white men.”

In large part, Democratic lawmakers in Washington and party officials across the country closed ranks around Biden despite the panic that gripped many of them from his debate performance. But their remarks were measured, seeming to leave an opening if Biden were to make the extraordinary decision to have Democrats find another nominee.

“It’s President Biden’s decision what he wants to do with his life,” said Sharif Street, chair of the Pennsylvania Democratic Party and a state senator. “So far, he’s decided he’s our nominee, and I’m with him.”

To be sure, plenty of Biden supporters saw nothing to throw them off, as much as they tended to think he blew it.

“Worrisome,” Jocardo Ralston of Philadelphia said of Biden’s turn on the stage. Yet, Ralston said, “I’m not conflicted, nor do I feel that I am choosing the lesser of two evils. ... Biden is not the ideal choice for many, but he is the only choice for me, without regrets or hesitation.”

Biden turned in a more spirited performance Friday at a rally in Raleigh, North Carolina, where he acknowledged he is not the debater he used to be.

“I know how to do this job,” he said. “I know how to get things done.”

He assailed Trump in ways that eluded him the night before.

“I thought ‘Well Joe, why didn’t you say that last night?’ ” said Maureen Dougher, 73, who found Biden “strong,” “definite” and “very clear” in his rally remarks.

Amina Barhumi, 44, of Orland Park, Illinois, is affiliated with Muslim Civic Coalition and is sizing up Biden and Trump in part on how she expects each will act on the interests of American Muslims. Count her as demoralized about the candidate choices, too. She’s hearing “essentially the same rhetoric” from both.

“We have not-so-great options that are front-runners on the ticket,” she said.

“Quite frankly, I think it was very difficult to watch,” she said of the debate. “I have teenagers and it felt like a bunch of bickering and nonsensical name-calling. And I think the American public expects more.”
