In another age, Joe Biden’s promise to heal the nation might have been regarded as the kind of blandishment expected from any new leader taking power after the divisive cut and thrust of an American election.But the next president will repeat the oath of office on Wednesday sealed off from those he governs by a global pandemic and the threat of violence from his predecessor’s supporters. Biden steps into the White House facing the unprecedented challenge not only of healing a country grappling with the highest number of coronavirus deaths in the world but a nation so politically, geographically and socially divided that seven in 10 Republicans say the election was stolen from Donald Trump.Surging Covid infections would have discouraged the crowds who usually turn out on the National Mall to welcome a new president. But the storming of Congress by right-wing extremists and white nationalists in support of Trump has prompted an almost total shutdown of the heart of American governance.Even before the assault on Capitol Hill, Biden warned that deepening partisanship was a threat to the stability of the United States.“The country is in a dangerous place,” he said during the election campaign. “Our trust in each other is ebbing. Hope is elusive. Instead of treating the other party as the opposition, we treat them as the enemy. This must end”.•••The enormity of the challenge was made starkly clear by the sacking of the Capitol. Most Americans recoiled in horror at the sight of their compatriots, some dressed as if ready for war, smashing up congressional offices, beating police officers and threatening to hang the vice-president. Five people died, including a member of the Capitol police.Yet more than 70% of Republicans agree with the protesters’ core claim that November’s election was rigged and say Biden is not the legitimate president. What will it take to even begin to heal the country, as Trump is likely to maintain his role as agitator in chief? The incoming president also faces a moment of racial reckoning in the wake of Black Lives Matter protests that have given new urgency of demands for America to reconcile with a bitter past and present.Polarisation is not going to go away no matter what he does in the short termCan Bideneven hold together the Democratic party, as its more liberal wing advocates for police reform, a green new deal and public healthcare – not policy positions which all moderates support.“We are so polarised that polarisation is not going to go away no matter what he does in the short term,” said Charles Franklin, director of the respected Marquette opinion poll in swing state Wisconsin.“The question is whether over a little bit longer term, let’s say over the course of the year, whether Biden can win over a segment of the population to create a majority that is both willing to give him a chance and is not unhappy with his performance. That’s up in the air but I don’t think it’s inconceivable.”The clamour for change that elected Barack Obama and then Trump has not gone away, and large numbers of Americans continue to believe the system does not work for them. For many Democrats, the key to addressing that is to think big and deliver while the party controls both houses of Congress, which may be for no more than two years.The incoming president faces the immediate challenge of intertwined health and economic crises caused by a pandemic that has killed nearly 400,000. Trump’s mishandling of coronavirus has left testing and vaccination rates woefully short of his promises, and unemployment claims are rising sharply again as the economy struggles with the latest wave of shutdowns, infections and deaths.Biden is likely to be judged swiftly on his ability to accelerate the pace of inoculations, presenting the opportunity to create early goodwill and momentum.In an early sign that he wants to be seen to act decisively, Biden on Thursday outlined $1.9tn in emergency relief, called the American Rescue Plan, including $400bn to deliver 100m vaccines in his first 100 days. The plan also directs more than $1tn to Americans through individual economic stimulus payments of $1,400 and increased unemployment benefits. It proposes more than doubling the national minimum wage to $15 an hour alongside other measure to alleviate child poverty.Biden has said the plan is only an interim measure and that more money will come. But even the present proposal will be too much for most Republicans in Congress and the bill will provide an early test of how far they are prepared to cooperate or if they will pursue the same obstructionist strategy deployed against Obama.Biden has the advantage of control but only by a slim margin in the House of Representatives and by relying on Vice-President Kamala Harris’s casting vote in the Senate. A lack of votes for the full package may force Biden to scale back his proposals but with them the incoming president put down a marker.David Paul Kuhn, author of The Hardhat Riot: Nixon, New York City and the Dawn of the White Working-Class Revolution, about the Democrats’ loss of their traditional blue collar base, said the incoming president has spoken more clearly about the struggle of working class communities than any since Bill Clinton in the 1990s.“Biden’s done a good job in sounding measured in a hyper-polarised environment, and that’s really important,” he said. “He gave several speeches targeted towards Obama-to-Trump voters. He acknowledged that they were forgotten and that he sees them now. Those were comments that we haven’t heard from any Democrat, like on the dignity of work, since Clinton. It was a significant step in the right direction.”Biden’s ability to deliver across a range of issues is something that preoccupies his supporters. Some Democrats are haunted by what they regard as a central lesson from the Obama years – the failure to seize the opportunities offered by the Great Recession when he took office in 2009, to reform an economic system that has worked against most Americans for at least four decades. To a part of America, Obama lookedto have rescued the banks while abandoning millions of ordinary people who lost their homes to foreclosure – helping drive some of the shift to Trump in 2016.Biden gave several speeches targeted towards Obama-to-Trump voters. He acknowledged that they were forgottenKuhn said Biden would do well to heed the lesson: “Barack Obama was talking about a new New Deal leading into December 2008 but there was no new New Deal. When Joe Biden was vice-president, there are the voters who lost the most jobs during the Great Recession while they saw stimulus payments going to the fat cats on Wall Street.”The pandemic has helped lay the ground for bold policies by once again exposing deep economic inequalities and the precarious financial position of large numbers of Americans. But Biden will have to tread carefully over key legislation pushed by the left of his party, particularly the green new deal which is hugely popular among some Democrats but reviled in parts of the country. Some Democrats think a relatively easy path would be a major spending bill to rebuild crumbling infrastructure, such as dangerously old bridges and dams, as well as new projects like high-speed rail. It would not only offer a vehicle to address some environmental issues but provide jobs and investment in some of the most neglected parts of the country.“An infrastructure bill might include a lot of clean energy but it would not be mistaken for the green new deal. It’s a good compromise that’s actually conceivably possible,” said Franklin.“I think infrastructure, of all the issues we deal with, it’s one that most easily resonates with working people, whether it’s construction work or highways, or water mains or electrical utilities. The irony is Trump talked a lot about infrastructure but never put forward a bill, when his own party probably would have thought it was pretty good.”•••Another challenge for Biden is to develop policies to address a sense of abandonment felt in mostly white rust belt and midwestern rural communities that were once solidly Democratwhile also addressing racial inequality and discrimination.“Biden talked about blue collar workers in his background, the people he grew up with,” said Franklin. “I thought that was an attempt to reach that disaffected blue collar, but not theneo-nazi Klan racist segment of the population. He tried to speak directly to those folks in a way that many see the Democratic party more generally is failing to do.”Kuhn said Biden should go further: “If he’s talking about common cause, he can push back against this fashionable notion in the United States that these families living pay cheque to pay cheque, that their struggle through life is actually a ‘privilege’ because they are white. Clearly, some portion of the American right feel that their frustrations don’t matter, because they happen also be white. ”Lilliana Mason, a professor of politics and author of Uncivil Agreement: How Politics Became Our Identity disagrees. She sees communities that provided bedrock support for Trump’s white nationalism and questions whether Biden will find backing even for programmes that help them.“There’s this increasing inequality which has created this kind of rural white Republican identity that’s based on white rural people feeling condescended to and that no one really listens to their needs,” she said. “But there’s also this resentment that their tax dollars go to the cities and to black people. They don’t want their tax dollars to help other people, meaning black people, even while it helps them.”The structural inequality that is rooted deep within our society must be addressedThose resentments may run even deeper if Biden follows through on promises to confront the challenge of building racial reconciliation in the age of resurgent white nationalism.Any incoming Democratic president faces pressure to address the legacy of centuries of systematic racism. The killing of George Floyd by the Minneapolis police, the wave of Black Lives Matter protests that followed and Trump’s feeding of hate has given an added urgency to demands for action.In his victory speech after beating Trump, Biden said he would “battle to achieve racial justice and root out systemic racism in this country”. His choice of Kamala Harris as vice-president was read as a statement that he will take racial equality seriously and he has nominated the most diverse cabinet in US history.But Biden failed to heed a call from the National Association for the Advancement Colored People to go further and create a new cabinet post “for racial justice, equity and advancement”. The NAACP president, Derrick Johnson, called the move a “bold action” that would demonstrate the incoming president’s commitment to elevating racial justice as a priority.“The structural inequality that is rooted deep within our society must be addressed, and after four years of regression on social, civil, and political matters that profoundly impact the American people, specifically, black people, we must prioritise the transformation of our nation into a more just, equal society in which all Americans can succeed and thrive,” he said.Biden has promised a raft of investments in creating in creating business opportunities, promoting homeownership and giving more education and training opportunities to underserved communities.But the new president remains cautious about how police reform will be read in the rest of the country. He told civil rights leaders that the cry to “defund the police” after Floyd’s death was misunderstood and damaging to the Democratic party, particularly candidates for Congress and in state races. Organisers in the rural midwest said the slogan, and the violence around some protests, was a major reason Trump’s vote went up in November, even in swing counties twice won by Obama.“That’s how they beat the living hell out of us across the country, saying that we’re talking about defunding the police,” Biden said last month according to an audio recording of a meeting published by the Intercept.He promised that there will be significant changes to the police but said how they are framed is important in winning broader public support. Franklin said there is a path that could unite not divide Americans.“When you ask about defund the police, it’s about 20% that favour of that. But when you talk about reform the police and hold police accountable, it’s like 70% or 80% in favour. Policing is very high on everybody’s list.”Biden will remain under pressure from black voters who were instrumental in his defeat of Trump, turning out in large numbers in midwestern cities to offset the white rural vote. They will want to know that their concerns are not just being heard but addressed, and that police reforms run deep as a litmus test of the new president’s commitment to racial reconciliation.Biden will also be under pressure from African American members of Congress, not least the majority whip, James Clyburn, who rescued the new president’s primary campaign a year ago.At the time Clyburn spoke of his own fears a year ago as he urged primary voters in South Carolina to back Biden who was on the back foot after a humiliating defeat in Iowa. “We are at an inflection point. I’m fearful for my daughters and their future and their children and their children’s future,” he saidThat speech helped Biden win South Carolina. A year later, it gives Clyburn leverage and the new president’s ear in ensuring the promise of racial reconciliation is not compromised by the desire to win over discontented whites.Biden’s criminal justice plan includes scrapping disparate sentencing for drug crimes that frequently results in longer sentences for African Americans for similar offences to those committed by whites, and for decriminalising marijuana.Biden also has a political incentive to confront voting rights for minorities given the escalation in Republican-controlled states of voter suppression which disproportionately keeps black people away from the polls.•••There are other policies likely to win support among large numbers of Americans, including some Trump voters, that would benefit underserved communities in particular.Biden has promised to write off up to $10,000 in student debt owed to the federal government. Democratic congresswoman Pramila Jayapal, the chair of the Congressional Progressive Caucus, said the issue was a litmus test of the new president’s commitment to helping the working poor.“There are a lot of people who came out to vote in this election who frankly did it as their last shot at seeing whether the government can really work for them,” she told the New York Times. “If we don’t deliver quick relief, it’s going to be very difficult to get them back.”Biden will be attempting to heal the divide in the face of what is expected to be a drumbeat of hostility from Trump who shows every intention of continuing to whip up anger and hate. At the core will be the claim that Biden stole the election, a powerful mantra among a section of voters that will keep the pressure on Republican legislators not to cooperate with the new president.Mason said whatever Biden does, the divisions in the country will remain stark.“It’s not just that those Trump supporters don’t like it that Biden’s president,” she said, “it’s that they fully believe that the election was stolen and he’s an illegitimate president. And as long as there are Republican leaders who are going to keep telling them that lie, they’re going to keep believing it. So to that extent, I don’t see any way to get away from a whole bunch of domestic terrorism happening during Biden’s term.” More
