President Trump's Twitter feed on April 3, 2017. (J. David Ake/AP)

Ted Koppel, managing editor of ABC News’s “Nightline” from 1980 to 2005, is senior contributor to CBS News’s “Sunday Morning.”

On July 21, 2016, just hours before he accepted the Republican presidential nomination, Donald Trump and I sat down for an interview. What he said on that occasion would serve as a remarkably candid foreshadowing of how Trump would handle his relationship with the media in what, on that day, seemed the unlikely event that he would actually become president.

“I don’t need you guys anymore,” Trump told me.

He pointed to his millions of followers on Twitter and Facebook, explaining that the days of television anchors and commentators acting as gatekeepers between newsmakers and the public were essentially over. Without discernible acrimony, Trump trotted out one of the early versions of what would eventually become a leitmotif of his presidency: The media was made up of largely terrible people trafficking in fake news. There was nothing personal in the observation. It was the unsheathing of a multipurpose device, one he used adroitly in tandem with the endlessly adaptable political vehicle provided by social media during the election campaign and now during his presidency.

Is there any reason to believe that what worked for Trump before he was elected and while in the White House won’t be equally effective after he leaves office?

There is a disarming innocence to the assumption that whether by impeachment, indictment or a cleansing electoral redo in 2020, President Trump will be exorcised from the White House and that thereby he and his base will largely revert to irrelevance.

It imagines that, for some reason, Trump in defeat or disgrace will become a quieter, humbler, more restrained presence on Twitter and Facebook than heretofore. It assumes further that CNN and Fox News and MSNBC, perhaps chastened by the consequences of their addictive coverage of Trump the Candidate and Trump the President, will resist the urge to pay similar attention to Trump the Exile.

Let the record show that Trump has launched the careers of numerous media stars and that expressions of indignant outrage on the left and breathless admiration on the right have resulted in large, entirely nonpartisan profits for the industry of journalism. Why anyone should assume that Trump and those who cherish or loathe him in the news business will easily surrender such a hugely symbiotic relationship is hard to understand.

It is all but inevitable that whoever succeeds Trump in the White House will be perceived by 30 to 40 percent of the voting public as illegitimate — and that the former president will enthusiastically encourage them in this perception. Whatever his failings, Trump is a brilliant self-promoter and provocateur. He showed no embarrassment, either as candidate or president, about using his high visibility to benefit his business interests. Untethered from any political responsibility whatsoever, he can be expected to capitalize fully on his new status as political martyr and leader of a new “resistance” that will make today’s look supine.

The dirty little secret about the United States’ relationship with Trump is that we have become addicted to him. His ups, his downs, his laughs, his frowns are (as the lovely song from “My Fair Lady” once put it in another context altogether) “second nature to [us] now, like breathing out and breathing in.”

When he fails to tweet for even a few hours, Trumpologists search for meaning in the silence. Hours are devoted on cable television, each and every day, to examining the entrails of his most recent utterances. Has there been a day in the past two years without a Trump-related story on the front page of every major U.S. newspaper? How does the president lie to us? Let us count the ways. And we do, endlessly, meticulously.

Do you believe for a moment that Americans are ready to give that up merely because, for one reason or another, Trump has been obliged to reoccupy Trump Tower full-time?

A President Pence would not satisfy that hunger. Nor, for now at least, is it easy to discern within the growing ranks of potential Democratic candidates a man or woman with a matching aura of glitz, a similar degree of shamelessness, a comparable pairing of so much to be humble about with a total lack of humility.

A new president may provide a sense of relief and normalcy. But he or she will not satisfy our craving for outrage. Trump’s detractors are outraged by him. His supporters are outraged with him. He is a national Rorschach test. Love him or hate him, you can’t ignore him. One way or another, Trump will be renewed for another season.
