Forget the pundits. Ignore New York Times editorials and columnists. Tune out people popping off on X, Mike Allen and Jim VandeHei write in a Behind the Curtain column.

• The only way President Biden steps aside, despite his debate debacle, is if the same small group of lifelong loyalists who enabled his run suddenly — and shockingly — decides it's time for him to call it quits.

Why it matters: Dr. Jill Biden; his younger sister, Valerie Biden; and 85-year-old Ted Kaufman, the president's longtime friend and constant adviser — plus a small band of White House advisers — are the only Biden deciders.

This decades-long kitchen cabinet operates as an extended family, council of elders and governing oligarchy. These allies alone hold sway over decisions big and small in Biden's life and presidency.

• The president engaged in no organized process outside his family in deciding to run for a second term, the N.Y. Times' Peter Baker reports.
• Then Biden alone made the decision, people close to him tell us.

Behind the scenes: If Biden stays in, it's for the same reason he decided to run again. He and the oligarchy believe he has a much better chance of beating former President Trump than Vice President Harris does.

• Biden allies have played out the scenarios and see little chance of anyone besides Harris winning the nomination if he stepped aside.
• Is the Democratic Party going to deny the nomination to the first woman, the first Black American, and the first South Asian American to be elected V.P.? Hard to see.
• These allies privately think Harris would struggle to pull moderate and swing voters, and would enhance Trump's chances. (Harris "fares only one or two points worse than Biden in polls with margins of sampling error that are much larger than that," The Washington Post found.)

The intrigue: We're told Democratic congressional leaders are one outside force that could bring pressure on Biden.

• They're getting calls and texts from panicked lawmakers who fear Biden's weakness could cost the party House and Senate seats in November.

"This is no longer about Joe Biden's family or his emotions," said an adviser in constant touch with the West Wing. "This is about our country. It's an utter f***ing disaster that has to be addressed."

• It'll take a while for the oligarchy to process the stakes, this adviser argued, "but there will be a reckoning."

Behind the scenes: Biden insiders are already finding it easier than many realized to rationalize staying in. They argue: Yes, he had a poor debate performance. But Biden also can dial up vigorous appearances like he did in Raleigh yesterday afternoon.

• That behind-the-scenes juxtaposition plays out daily: Sometimes he's on his game, sharper than people would think, and quicker on his feet.
• But often it's the Biden you saw on the debate stage: tired, slow, halting.

Top Democrats saw what America saw live, on national TV, vividly and unforgettably. They can't unsee it. And they fear voters won't unsee it.

• No longer can they blame critics or edited footage or media exaggeration.
• Every misstep, verbal hiccup or frozen face will zip across social media and TV, reminding voters Biden will be 86 years old at the end of his second term.

"They need to tell him the absolute truth about where he is," said a well-known Democrat who often talks to the president. "Loyalty doesn't mean blind loyalty."

• "Candidates for House, Senate, governor, state legislature are going to be in survival mode," the well-known Democrat added. "They're not going to go down with the ship. And the ship is in a bad place."

Some Biden family members are digging in — squinting at overnight polls for signs that undecided voters moved Biden's way because of Trump statements at the debate, Mike and Jim write.

• "They know it was a disaster," said a source close to the family. "But they think there's a glimmer of survival/hope."
• In a Biden campaign memo, "Independent Voters Move to Biden in Debate," officials wrote: "Based on research we conducted during [the] debate, it is clear that the more voters heard from Donald Trump, the more they remembered why they dislike him."

🎤 Biden — bolstered by a tweet from former President Obama ("Bad debate nights happen. Trust me, I know") — sounds like he wants to stick it out.

• "When you get knocked down, you get back up," Biden said to applause, reading from a teleprompter yesterday at the North Carolina State Fairgrounds.
• "Folks, I don't walk as easy as I used to. I don't speak as smoothly as I used to. I don't debate as well as I used to. But ... I know how to tell the truth."

🕶️ What we're watching: The public backing of former presidents and current members of Congress says little about Biden's future.

• Most know him too well and for too long to humiliate him in public.
• Instead, if he decides to go, it'll follow private conversations with them — then a decision with this oligarchy. Remember, it's under eight weeks until Biden is ratified as the official nominee. That's the clock to watch.

⚜️ James Carville — the "Ragin' Cajun" who masterminded Bill Clinton's first presidential campaign in 1992, and now is a frequent TV pundit — will be 80 in October. He told us that if he appeared like Biden did during the debate, he'd want to be pulled off the tube.

• "I never thought this was a nifty idea," Carville said of Biden's run. He said there are few people the president really listens to: "He doesn't have advisers. He has employees."

When we pressed Carville on whether he thinks Biden will be off the ticket by Election Day, he said he thinks so. He invoked a famous quote by the late economist Herb Stein, which Carville paraphrased as: "That which can't continue … won't."

The past 36 hours showcased two Joe Bidens: the veteran president rallying voters in a swing state, and an 81-year-old man struggling to string thoughts together in a debate, Axios' Alex Thompson reports.

• Why it matters: The split screen isn't new inside the White House. To try to blunt concerns about Biden's age, top aides have meticulously stage-managed such minutiae as his sleep schedule, his orthopedic shoes, his walks to Marine One and his climb aboard Air Force One.

Internally, many aides have seen flashes of an absent-minded Biden. They typically brush these moments off as ordinary brain farts because they usually see him engaged, eight current and former Biden officials told Axios.

• But the debate shattered White House efforts to show Biden at his best: a president capable of serving until 2029, when he'd be 86. Biden often looked lost or slack-jawed, and delivered meandering answers in a hoarse voice.

Some campaign aides projected calm yesterday, framing the debate as just a bad night that they'd recover from. Other aides, donors and senior Democrats were deeply shaken.

• The aides even expressed new worries about whether the president could carry out his duties through another four-year term.

⏰ Behind the scenes: From 10 a.m. to 4 p.m., Biden is dependably engaged. Many of his public events are held within those hours.

• Outside that time range, or while traveling abroad, Biden is more likely to have verbal miscues and become fatigued.

Some of the close-knit Biden aides who prepped him for the debate told confidants beforehand that they were optimistic — that he'd done well in their practice sessions.

• After Thursday's 90-minute debate, which began at 9 p.m., CNN's cameras captured Dr. Jill Biden gingerly helping her husband descend the few stairs by the podium.

When they write the history books about this era of the Supreme Court, its decimation of presidents' regulatory powers will loom just as large as any other issue, Axios' Sam Baker writes.

• Why it matters: Every modern president leans heavily on executive actions to advance their agenda. Democrats, in particular, use federal agencies for climate, health and tech regulation. Those days are numbered.

Between the lines: These rulings aren't always the ones that grab the public's attention.

• But the consequences are forever. They touch just about every executive action of any significance that any future president will ever attempt.

💨 Catch up quick: In a 6-3 decision, the court yesterday overturned the doctrine known as "Chevron deference."

• When Congress writes laws, it directs Executive Branch agencies to implement those laws. The regulations those agencies write are often challenged in court.
• Chevron held that, when the courts are dealing with one of those disputes — and when the underlying law is vague or unclear about what the relevant agency should do — the courts will defer to the agency's interpretation, as long as it's reasonable.

🔮 What's next: Expect to see more aggressive legal challenges to decisions from the EPA, the FDA and tech regulators, including the FCC and FTC.

Organizers at the Euro 2024 soccer tournament in Germany have had to increase security because fans have gotten so aggressive about seeking selfies with Cristiano Ronaldo.
