Biden’s trajectory is a Shakespearean tragedy. Clooney can play the president | Sidney Blumenthal

George Clooney can now play Joe Biden in the movie. After he urged the president to quit the race, the penultimate scene became greater than any Hollywood ending. The actor, while the King of Hollywood, has not yet won an Oscar. This part, though, drawing on a range of classic genres, moving from pathos to tragedy to triumph, will challenge his dramatic skills as never before.

The curtain rises on Biden as Richard II, beleaguered and beset, facing his overthrow from within.

What must the king do now? Must he submit?

The king shall do it: must he be deposed?

The king shall be contented: must he lose

The name of king? o’ God’s name, let it go

The Shakespearean inevitability seems overwhelming, tragedy heaped upon tragedy with a comic thread: the plotting against him from Julius Caesar, his rages against fate from King Lear, and reality suspended with a touch of A Midsummer’s Night Dream. Then in a thunderclap the drama turns romantic through Byron’s Ode to Napoleon Buonaparte.

Tis done – but yesterday a King

And arm’d with Kings to strive –

And now thou art a nameless thing

So abject – yet alive!

In 2011, Clooney wrote the screenplay for a film called The Ides of March in which he played an idealistic Pennsylvania governor and Democratic presidential candidate reacting to cynical plots and subplots. The New York Times called it “less an allegory of the American political process than a busy, foggy, mildly entertaining antidote to it”. Clooney did receive an Oscar nomination for his writer’s credit but no more.

Now he can play in something other than a belabored story of the supposed price idealism pays to ambition. Now he can sink his teeth into a far more complicated starring role, following a far richer storyline.

The film begins with a bright young star of the post-JFK generation from a middle-class background with an unusual common touch yet stricken by unspeakable tragedy and trauma. His wife and daughter are killed in a car accident, and his two sons are critically injured. Though just elected to the Senate at the age of 29, one of the youngest ever, he devotes himself to his sons. He travels daily on the train from Washington to his home in Delaware to watch over them, while still establishing himself as a peer among his fellow senators despite his youthful age.

In the second arc, Biden launches a campaign for his party’s presidential nomination but wrecks his chance by borrowing the identities of various political figures put into his mouth by overheated media consultants. His earnest ambition is undone by trivial mendacity, his promise upended by careless overreaching.

Then he is the chair of the US Senate judiciary committee, seeking respect, comity and bipartisan cooperation, presiding over the nomination of a US supreme court nominee who perjures himself about his sexual harassment of an employee. In the interest of misguided fairness, the senator suppresses the evidence of two corroborating witnesses.

Again, he runs for his party’s nomination, now the even more powerful and knowledgeable chair of the Senate foreign relations committee, but he wins less than 1% of the vote in the Iowa caucus and glumly drops out. A charismatic up-and-comer who had served hardly any time in the Senate emerges victorious, then lifts the loser from the depth of his political despair to make him his perfectly complementary running mate.

Biden emerges as a substantive vice-president, the consummate negotiator with Congress to help enact the signature achievement of the administration, the long-held dream of national health insurance. But, again, personal tragedy strikes. His beloved son, Beau, rising in politics after a military career, whom his father had pinned for a trajectory to the White House, attaining what he could not, contracts brain cancer and dies. As Biden copes with his grief, the president passes over him as his chosen successor to anoint another, who narrowly loses to a vile grifter posing as a man of the people.

Again, Biden appears to stumble out of the gate yet in another run, but regains his footing. He is the only one who can bridge the whole of the party. As hundreds of thousands die during a plague-like pandemic, the economy withers. He stands as a figure of empathy and solidity against the malignant narcissist in the Oval Office. At last, when Biden wins the prize, Donald Trump stages an insurrection to prevent the certification of the election and departs in disgrace.

He is blamed for his extraordinary but incomplete success. Trump rises from his ruins to be acclaimed through willfully blind nostalgia

Despite razor-thin margins in the Congress, he passes the most far-ranging legislation since the Great Society, manages the economy through its complex hazards, expands the western alliance in the teeth of Vladimir’s Putin’s aggression against Ukraine, and gets little credit. He is healing the world, but the toxicity lingers. He is blamed for his extraordinary but incomplete success. Trump rises from his ruins to be acclaimed through willfully blind nostalgia.

Once too young for his responsibility, Biden is assailed as too old to hold it. There is a bit of The Last Hurrah about his last campaign, also played by Spencer Tracy in the film based on the Edwin O’Connor novel of an old Irish-American Boston mayor who, on his deathbed, responding to the talk around him that he would have done it all differently if he could live his life over, says as his last words: “Like hell I would.”

Against the tide of criticism for months, Biden knows he is not suffering from cognitive decline that affects his judgment as president. He is handling the crises around the globe with skill and experience, the master of foreign policy. He has defeated the menace of Trump before. But he has occasional lapses from natural aging. He tires; he forgets a name or place. His childhood stutter seems to have made a partial return as he pauses to form and explain his thoughts. He has taken cognitive tests, previously unknown to the public, that demonstrate he has no underlying condition. But he assumed the burden of running again out of a sense of duty that he is best able to meet the troubled times.

He stubbornly resists and takes umbrage at the chorus of criticism at his obvious aging, his halting and slow gait from a broken foot early in his presidency he didn’t properly treat and his sometimes broken sentences. In his mind, he’s saving the country.

He offers an early debate to dispel what he considers the smears of his disability. He and his staff are certain he can repeat his adroit State of the Union appearance. But he falters and loses his place and looks painfully old. He makes subsequent public appearances to put the lie to his collapse as just “a bad night”. After a successful Nato summit, at a press conference he displays his intricate knowledge and management of foreign policy. Yet the press is not quelled. Pundits describe him as clinging to power as a selfish old man, his refusal to leave proving he’s as bad as Trump.

Nancy Pelosi, now the speaker emerita, as she calls herself, still the regnant monarch of the Congress, recognizes his flaw as fatal political decline. She orchestrates a slow process of persuasion, of regretful statements from a trickle of members urging him to withdraw, which threatens to become a torrent.

Barack Obama, muffled behind the curtain, lends his assent, if not by silence, to the critics. His multitude of former aides, spread throughout the media as kibitzers, have raised their voices as a chorus of Biden naysayers. Obama does not wave off Clooney, the actor casting himself the party broker. Biden feels betrayed. He is given to bouts of self-pitying, defiant and angry cries, but these do not hold off the ranks from further dividing or the walls from closing in.

On 13 July, an assassin nicks Trump at a rally. The terrible event gives him the unprecedented possibility at the Republican convention to appear as a transformed figure. He could use his narrow escape to reveal an inner conversion. But after his entrance to the lights flashing his name, like the old Elvis in Las Vegas, after describing what happened to him when the bullet went by his head, he reverted to the fossilized Trump. For a droning hour and a half, he fell into his lounge act of canned jokes and insults. Since then, he has declined further into his decadent routine. At his first rally since Butler, he went on about Nancy Pelosi as a “dog” and “crazy as a bedbug”, Kamala Harris as “crazy”, and Biden as “stupid”. His encounter with death could not alter his character. With each slur and slight, Trump shrinks himself.

Biden catches Covid-19. He retreats to his home in Delaware. He contemplates his mortality in the scale of his duty. He can read the polls. He comes to the epiphany that he could achieve his aims only by relinquishing his pride. He rose to the figure in Byron’s Ode:

Where may the wearied eye repose

When gazing on the Great;

Where neither guilty glory glows,

Nor despicable state?

Yes – one – the first – the last – the best –

The Cincinnatus of the West,

Whom envy dared not hate,

Bequeath’d the name of Washington,

To make man blush there was but one!

When George III learned that George Washington would resign after his term, voluntarily give up the office of the presidency to establish the principle of a peaceable transfer of power and preserve the American Republic, the King remarked: “If he does that, he will be the greatest man in the world.”
