Donald Trump will walk out of the White House and board Marine One for the last time as president Wednesday morning, leaving behind a legacy of chaos and tumult and a nation bitterly divided.

Four years after standing on stage at his own inauguration and painting a dire picture of “American carnage”, Trump departs the office twice impeached, with millions more out of work and 400,000 dead from the coronavirus. Republicans under his watch lost the presidency and both chambers of Congress. He will be forever remembered for the final major act of his presidency: inciting an insurrection at the Capitol that left five dead — including a Capitol Police officer — and horrified the nation.

Trump will be the first president in modern history to boycott his successor’s inauguration as he continues to stew about his loss and privately maintains the election that President-elect Joe Biden fairly won was stolen from him. Republican officials in several critical states, members of his own administration and a wide swath of judges, including those appointed by Trump, have rejected those arguments.

Still, Trump has refused to participate in any of the symbolic passing-of-the-torch traditions surrounding the peaceful transition of power, including inviting the Bidens over for a get-to-know-you visit.

By the time Biden is sworn in, Trump will already have landed at his private Mar-a-Lago club in West Palm Beach, Florida, to face an uncertain future — but not before giving himself a grand military sendoff, complete with a red carpet, military band and 21-gun salute.

Guests have been invited, but it is unclear how many will attend. Even Vice President Mike Pence plans to skip the event, citing the logistical challenges of getting from the air base to the inauguration ceremonies. Washington has been transformed into a security fortress, with thousands of National Guard troops, fencing and checkpoints to try to stave off further violence.

Aides had urged Trump to spend his final days in office trying to salvage his legacy by highlighting his administration’s achievements — passing tax cuts, scaling back federal regulations, normalising relations in the Middle East. But Trump largely refused, taking a single trip to the Texas border and releasing a video in which he pledged to his supporters that "the movement we started is only just beginning".

Trump will retire to Florida with a small group of former White House aides as he charts a political future that looks very different now than just two weeks ago.

Before the Capitol riot, Trump had been expected to remain his party’s de facto leader, wielding enormous power as he served as a kingmaker and mulled a 2024 presidential run. But now he appears more powerless than ever — shunned by so many in his party, impeached twice, denied the Twitter bullhorn he had intended to use as his weapon and even facing the prospect that, if he is convicted in his Senate trial, he could be barred from seeking a second term.

For now, Trump remains angry and embarrassed, consumed with rage and grievance. He spent the week after the election sinking deeper and deeper into a world of conspiracy, and those who have spoken with him say he continues to believe he won in November. He continues to lash out at Republicans for perceived disloyalty and has threatened, both publicly and privately, to spend the coming years backing primary challenges against those he feel betrayed him.

Some expect him to eventually turn completely on the Republican Party, perhaps by flirting with a run as a third-party candidate as an act of revenge.

For all the chaos and drama and bending the world to his will, Trump ended his term as he began it: largely alone. The Republican Party he co-opted finally appeared to have had enough after Trump’s supporters violently stormed the Capitol, hunting for lawmakers who refused to go along with Trump’s unconstitutional efforts to overturn the results of a democratic election.

But although Washington may have had enough, Trump retains his grip on the Republican base, with the support of millions of loyal voters, along with allies still helming the Republican National Committee and many state party organisations.

The city he leaves will not miss him. Trump rarely left the confines of the White House, except to visit his own hotel. He and his wife never once ate dinner at any other local restaurant; never ventured out to shop in its stores or see the sites. When he did leave, it was almost always to one of his properties: his golf course in Virginia, his golf course in New Jersey, his private club and nearby golf course in Palm Beach, Florida.

The city overwhelmingly supported Biden, with 93 per cent of the vote. Trump received just 5.4pc of the vote — or fewer than 18,600 ballots — not enough to fill the Washington Capitals hockey arena.
