I still have trouble seeing how the Trump administration survives a full term. Judging by his Thursday press conference, President Trump’s mental state is like a train that long ago left freewheeling and iconoclastic, has raced through indulgent, chaotic and unnerving, and is now careening past unhinged, unmoored and unglued.

Trump’s White House staff is at war with itself. His poll ratings are falling at unprecedented speed. His policy agenda is stalled. F.B.I. investigations are just beginning. This does not feel like a sustainable operation.

On the other hand, I have trouble seeing exactly how this administration ends. Many of the institutions that would normally ease out or remove a failing president no longer exist.

There are no longer moral arbiters in Congress like Howard Baker and Sam Ervin to lead a resignation or impeachment process. There is no longer a single media establishment that shapes how the country sees the president. This is no longer a country in which everybody experiences the same reality.

Everything about Trump that appalls 65 percent of America strengthens him with the other 35 percent, and he can ride that group for a while. Even after these horrible four weeks, Republicans on Capitol Hill are not close to abandoning their man.

The likelihood is this: We’re going to have an administration that has morally and politically collapsed, without actually going away.

What does that look like?

First, it means an administration that is passive, full of sound and fury, but signifying nothing. To get anything done, a president depends on the vast machinery of the U.S. government. But Trump doesn’t mesh with that machinery. He is personality-based while it is rule-based. Furthermore, he’s declared war on it. And when you declare war on the establishment, it declares war on you.
