When Joseph R. Biden Jr. served as vice president in the Obama administration, he was known to preface his recommendations to other officials with a self-deprecating disclaimer. He may not have attended Harvard or Yale, Mr. Biden would say as he popped into an office or a meeting, but he was still a foreign policy expert, and he knew how to work Capitol Hill.
Mr. Biden isn’t apologizing anymore.
Now 100 days into his presidency, Mr. Biden is driving the biggest expansion of American government in decades, an effort to use $6 trillion in federal spending to address social and economic challenges at a scale not seen in a half-century. Aides say he has come into his own as a party leader in ways that his uneven political career didn’t always foretell, and that he is undeterred by matters that used to bother him, like having no Republican support for Democratic priorities.
For an establishment politician who cast his election campaign as a restoration of political norms, his record so far amounts to the kind of revolution that he said last year he would not pursue as president — but that, aides say, became necessary to respond to a crippling pandemic. In doing so, Mr. Biden is validating the desires of a party that feels fiercely emboldened to push a liberal agenda through a polarized Congress.
The result is something few people expected: His presidency is transforming what it means to be a Democrat, even among a conservative wing of his party that spent decades preaching the gospel of bipartisanship.
“We’ve been very happy with his agenda and we’re the moderates,” said Matt Bennett, a co-founder of Third Way, a Democratic think tank named after a governing style embraced by former President Bill Clinton that rejected liberal orthodoxy. “Some have said this is a liberal wish list. We would argue that he is defining what it is to be a 21st-century moderate Democrat.”
Mr. Biden trumpeted his expansive agenda again on Wednesday night in his first address to Congress, casting his efforts to expand vaccinations and pour trillions of dollars into the economy as a way to unify a fractured nation.
“We’re vaccinating the nation; we’re creating hundreds of thousands of new jobs,” he said. “We’re delivering real results to people — they can see it and feel it in their own lives.”
Mr. Biden, now 78, has pursued these sweeping changes without completely losing his instinct for finding the center point of his party. As the Democratic consensus on issues has moved left over the years, he has kept pace — on abortion, gun control, same-sex marriage, the Iraq war and criminal justice — without going all the way to the furthest liberal stance. Now, he is leading a party that accelerated leftward during the Trump administration, and finding his own place on the Democratic spectrum — the one with the most likelihood of legacy-cementing success.
In private calls with Senator Bernie Sanders of Vermont, whom he vanquished in the Democratic primaries, he collects ideas from the party’s liberal wing. With Senator Joe Manchin, the centrist West Virginia Democrat, he keeps tabs on his caucus and its slim congressional margins. And in conversations with Senator Mitch McConnell, the Republican minority leader and a longtime negotiating partner, Mr. Biden appeals for bipartisan support, even as he warns that he won’t wait for it indefinitely.
“Biden is a politician who stays inside of the moment,” said Rashad Robinson, president of racial justice organization Color of Change, which was skeptical of Mr. Biden during the primary but now praises his work. “He stays inside of where the cultural context has moved.”
To the consternation of some Republicans, Mr. Biden is approaching politics differently from recent Democratic presidents who believed that support from the opposing party would provide a bulwark for their policies and political standing. In the 1990s, Mr. Clinton espoused triangulation, a strategy that forced liberals to settle for moderate policies by cutting deals with Republicans. Former President Barack Obama spent months trying to win bipartisan buy-in for his policy proposals.
Both strategies were rooted in political fears that began in the Reagan era: Doing too much to assuage the party’s left flank could alienate voters in the middle who took a more skeptical view of government, leaving Democrats unable to build coalitions for re-election.
Mr. Biden and his administration have embraced a different philosophy, arguing that difficult times have made liberal ideas popular with independents and some Republican voters, even if G.O.P. leaders continue to resist them.
The shift leftward, aides say, reflects a recognition by Mr. Biden that the problems facing the country require sweeping solutions, but also that both parties changed during the polarizing years of the Trump administration. Gone is the Senate where Mr. Biden spent decades, legislating like former President Ronald Reagan, who liked to say he’d call any negotiation where he could get 70 percent of what he wanted a win.
“There’s a difference between President Biden and Senator Biden,” said former Senator Chuck Hagel, a Republican who served for decades with Mr. Biden and supported his presidential bid. “Even a difference between President Biden and Vice President Biden. He’s the president now and he’s got the responsibility of trying to move this country forward. Yes, he wants to do it in a bipartisan way if he can. But the fact is these problems aren’t going to solve themselves.”
Other Republicans see a more dissembling president, one who has broken his promises to reach across the aisle. In a floor speech on Wednesday afternoon, Mr. McConnell accused Mr. Biden of “false advertising” during his campaign, saying Americans “elected a president who preached moderation.”
He added: “Over a few short months the Biden officials seems to have given up on selling actual unity in favor of catnip for their liberal base.”
In his address, Mr. Biden said he was open to hearing Republican ideas on his infrastructure plans — but wouldn’t wait forever.
“I applaud a group of Republican senators who just put forward their proposal,” he said. “We welcome ideas. But the rest of the world isn’t waiting for us. Doing nothing is not an option.”
The decades Mr. Biden spent cultivating a moderate image, paired with the conciliatory tone he has adopted toward Republicans in public, has allowed him to push his agenda without facing charges of socialism — a label his opponents unsuccessfully tried to make stick during the presidential campaign.
Focus groups throughout the campaign found that voters felt they knew Mr. Biden, both for his family story and working class bona fides. Even now, voters rate Mr. Biden as more moderate than Mr. Obama at the same stage of his presidency, according to polling from NBC News. Mr. Biden is pursuing a more liberal agenda than Mr. Obama did, of course; but he is taking a lower-key approach and advancing relatively popular ideas, and he doesn’t face the same smears and attacks as Mr. Obama did as the first Black president.
“It’s been very artful because it’s allowed him to create this weird equilibrium where people don’t see him as a partisan ramrod, which gives comfort to moderates,” said David Axelrod, a former top adviser to Mr. Obama. “On the other hand, he’s really moving forward on a lot of these initiatives.”
Aides and allies say the Jan. 6 attack on the Capitol also affected Mr. Biden’s thinking about what the country might accept politically. The soon-to-be president believed the violence alienated a slice of voters from Mr. Trump’s Republican Party, leaving them more open to Mr. Biden’s agenda, particularly if he delivered tangible government benefits like stimulus checks and vaccines.
“It’s fair to say that Obama followed the Clinton model, and Biden is not, in some fundamental ways, because the world has changed so profoundly,” Mr. Bennett said. “Joe Biden is dealing with a seditious, anti-democratic set of lunatics. You can’t deal with people who voted to overturn the election. You simply cannot, even if you’re a moderate.”
Mr. Biden’s predecessor helped till the ground in other ways. As Mr. Trump focused his attention on waging baseless attacks against the election results last winter, coronavirus cases surged across the country, leaving Americans eager for more economic and public health assistance; Mr. Biden provided that with a $1.9 trillion stimulus bill just a few weeks into his presidency.
“Joe Biden is living in a honeymoon with a prenup signed by Donald Trump,” said Rahm Emanuel, who was Mr. Obama’s chief of staff.
Yet some longtime friends and allies also see a more personal evolution in Mr. Biden since he assumed the role of president.
His inner circle says he is exhibiting a level of confidence they’ve never seen before, combined with an awareness that he only has a short window to achieve his goals before next year’s midterm elections, which could cost Democrats their slim governing majority. While Mr. Biden has said his “expectation” is that he’ll run again, political allies privately admit that remains an open question given his age.
Mr. Biden’s administration has not given liberals everything they’ve wanted, pushing back on proposals to cancel student debt, adopt the entirety of the Green New Deal and completely eliminate the filibuster.
During negotiations with Mr. Sanders’s team last summer over a shared platform that would unify Democrats behind Mr. Biden’s general election candidacy, Biden aides made clear that they would not accept any recommendations that they didn’t believe he could support if elected. At one point, they agreed to decriminalize marijuana but rejected a plan to legalize it completely, saying Mr. Biden didn’t agree with that policy, according to a person involved in the talks.
But Mr. Biden didn’t treat the negotiations as simply optics, an encouraging sign to many progressives that Mr. Biden and his team were committed to pursuing more-liberal policies than they had realized.
Mr. Biden’s advisers said they were perplexed by the progressive zeal over the president’s economic agenda, noting that the America Jobs Plan is exactly what Mr. Biden promised he would do during his campaign. The view from inside the West Wing is that liberals and Republicans both made false assumptions about Mr. Biden and how he would govern.
Aides argue that Mr. Biden hasn’t changed from the candidate who just months ago promised to find “between four and eight Republican senators” to support his policies. He’s still the politician who would be more comfortable compromising on his proposals, getting less than what he wanted, but passing legislation with Republicans on board. He still describes Mr. McConnell as a friend, and thinks he might have come in with a better shot at getting his support than Mr. Obama.
Aides also say he believes that bipartisan support, in the long term, will be more important for the country than passing his $4 trillion infrastructure bills untouched, through reconciliation.
“In his heart, he probably still would love to forge bipartisan deals,” Mr. Axelrod said. “But he’s going to be judged at the end of the day not on style points but what he gets done, and he knows that.”
