The root of the problem is the president’s amorality. Anyone who works with him knows he is not moored to any discernible first principles that guide his decision making.

Although he was elected as a Republican, the president shows little affinity for ideals long espoused by conservatives: free minds, free markets and free people. At best, he has invoked these ideals in scripted settings. At worst, he has attacked them outright.

In addition to his mass-marketing of the notion that the press is the “enemy of the people,” President Trump’s impulses are generally anti-trade and anti-democratic.

Don’t get me wrong. There are bright spots that the near-ceaseless negative coverage of the administration fails to capture: effective deregulation, historic tax reform, a more robust military and more.

But these successes have come despite — not because of — the president’s leadership style, which is impetuous, adversarial, petty and ineffective.

From the White House to executive branch departments and agencies, senior officials will privately admit their daily disbelief at the commander in chief’s comments and actions. Most are working to insulate their operations from his whims.

Meetings with him veer off topic and off the rails, he engages in repetitive rants, and his impulsiveness results in half-baked, ill-informed and occasionally reckless decisions that have to be walked back.

The erratic behavior would be more concerning if it weren’t for unsung heroes in and around the White House. Some of his aides have been cast as villains by the media. But in private, they have gone to great lengths to keep bad decisions contained to the West Wing, though they are clearly not always successful.

It may be cold comfort in this chaotic era, but Americans should know that there are adults in the room. We fully recognize what is happening. And we are trying to do what’s right even when Donald Trump won’t.

The result is a two-track presidency.

Take foreign policy: In public and in private, President Trump shows a preference for autocrats and dictators, such as President Vladimir Putin of Russia and North Korea’s leader, Kim Jong-un, and displays little genuine appreciation for the ties that bind us to allied, like-minded nations.

Astute observers have noted, though, that the rest of the administration is operating on another track, one where countries like Russia are called out for meddling and punished accordingly, and where allies around the world are engaged as peers rather than ridiculed as rivals.

On Russia, for instance, the president was reluctant to expel so many of Mr. Putin’s spies as punishment for the poisoning of a former Russian spy in Britain. He complained for weeks about senior staff members letting him get boxed into further confrontation with Russia, and he expressed frustration that the United States continued to impose sanctions on the country for its malign behavior. But his national security team knew better — such actions had to be taken, to hold Moscow accountable.

This isn’t the work of the so-called deep state. It’s the work of the steady state.

Given the instability many witnessed, there were early whispers within the cabinet of invoking the 25th Amendment, which would start a complex process for removing the president. But no one wanted to precipitate a constitutional crisis. So we will do what we can to steer the administration in the right direction until — one way or another — it’s over.

The bigger concern is not what Mr. Trump has done to the presidency but rather what we as a nation have allowed him to do to us. We have sunk low with him and allowed our discourse to be stripped of civility.

Senator John McCain put it best in his farewell letter. All Americans should heed his words and break free of the tribalism trap, with the high aim of uniting through our shared values and love of this great nation.

We may no longer have Senator McCain. But we will always have his example — a lodestar for restoring honor to public life and our national dialogue. Mr. Trump may fear such honorable men, but we should revere them.

There is a quiet resistance within the administration of people choosing to put country first. But the real difference will be made by everyday citizens rising above politics, reaching across the aisle and resolving to shed the labels in favor of a single one: Americans.
