CNN  — 

President Joe Biden can report in his first prime-time address Thursday that a vaccination drive now reaching 2 million people daily has brought America far closer to exiting the pandemic than when he took office 50 days ago.

With new infections and deaths way down from their peaks of a horrific winter, Biden can afford to conjure hope that better days may be imminent and will speak to the nation from a position of political strength. He is also armed with a newly passed $1.9 trillion Covid-19 rescue package – his first major legacy achievement – which represents an ambitious attempt to rebuild the US economy to favor the less well off.

“This bill represents a historic, historic victory for the American people,” Biden said Wednesday, touting his rescue plan that finally cleared Congress on Wednesday and pivoting to an address that he said would inform the country what “comes next” in the effort to prevail over the coronavirus.

A clear majority of Americans – 60% – approves of the new President’s handling of the pandemic in a new CNN poll. He has reintroduced the nation to calm, functional leadership and a scientific approach to the public health crisis, and has ended the stream of vitriol that poured from the Oval Office for four years.

Yet in a national crisis this deep and in a country so polarized less than two months since ex-President Donald Trump’s insurrection, nothing is remotely normal. While Biden honored campaign promises to take the virus seriously, to secure funds to get kids back to school and to help Americans pummeled by the economic crisis, his White House is weighed down by stark challenges.

A White House official said Biden’s Thursday night speech, expected to last about 20 minutes, would focus on the lives lost and changed in the pandemic and the work Biden’s administration has done to rapidly increase the vaccination effort. The President will also explain what must still be done to defeat the virus, the official said.

The virus is far from purged. Covid-19 variants may trigger a new spring surge in infections before vaccination campaigns can tamp them down. Republican governors racing to open their states with cases still at a high plateau could also cause a new wave of unnecessary deaths.

It will be a massive task to ensure a swift, smooth disbursement of American Rescue Plan largesse and to get money quickly into vaccination drives, for example, in ways that speed the pandemic endgame. Any corruption or bureaucratic glitches will only fuel Republican claims the plan is a massive liberal handout.

A fast-building southern border crisis threatens to turn into the first big non-Covid-19-related emergency of this presidency, with Biden yet to get a handle on a surge of undocumented child migrants across the border. The issue is perilous for him because it is one area where a reeling Republican Party may gain traction on one of its key issues. Biden garnered one of his lowest ratings in the CNN poll – only 43% approval – on immigration.

The White House hopes to repair Biden’s reputation for bipartisan compromise – battered by unanimous GOP opposition to the Covid-19 rescue plan – with an infrastructure package. But when the President ventures into more controversial legislative areas, such as a vast voting rights bill that has already passed the House and a climate bill, his popularity will come under pressure. He will have to consider a nuclear option of seeking to abolish or at least amend Senate filibuster rules that allow Republicans to easily kill legislation.

Controversial foreign policy gambits like an attempt to coax Iran back into a nuclear deal will also expose Biden to attacks at home.

A historically fast start

Biden’s success – along with Democratic leaders – in piloting a massive piece of legislation through Congress despite the tightest of majorities in the first weeks of his presidency is a historic achievement that ranks alongside the fastest of starts by modern presidents. The new law delivers on his promise to send $1,400 stimulus payments to millions of Americans.

If Biden succeeds in making a flurry of child tax credits, health insurance subsidies and nutrition assistance measures permanent, he will deserve a place in the pantheon behind reforming Democratic presidents such as Lyndon Johnson and Franklin Roosevelt, who used vast federal power to lift Americans out of poverty.

In a White House memo obtained by CNN on Wednesday, officials vowed to sell the American people on the benefits of the legislation and to get cash rolling immediately. “The implementation of the Rescue Plan is going to be an all-hands-on-deck effort across the administration,” White House deputy chief of staff Jen O’Malley Dillon wrote in the memo.

What was true at the start of the Biden administration remains true now: The President will be judged on his capacity to bring the country out of the pandemic. If he succeeds in leading America back to normality this year, his place in history will be secure whatever else happens in his term. The blanket Republican opposition to the Covid-19 bill may also look like a bad bet.

Since taking office, Biden has led the nation in mourning for 525,000 lost citizens and has managed a steady rise in vaccinations, which now average 2 million a day. He is on course to blast past his target of 100 million vaccines in arms in his first 100 days. While his team has been unwilling to credit the previous administration’s work in helping to develop the vaccine, it has put in place tangible improvements in what was a threadbare rollout effort.

The overhaul of the US counter-pandemic strategy after Trump’s denial and mismanagement and Biden’s success in passing the Covid-19 rescue plan leave an impression that the new President is effectively wielding the tools of his office, after a lifetime Washington apprenticeship.

The agreement he brokered for Merck to manufacture a Covid-19 vaccine developed by its rival Johnson & Johnson, for example, appeared to be a far more effective use of the wartime powers in the Defense Production Act than was managed by the Trump administration. And Biden’s intervention helped coax moderate Democratic Sen. Joe Manchin of West Virginia on board the rescue act – an unabashed liberal bill.

Biden’s impact is also being felt in the way he has restored traditional expectations of presidential behavior and has projected human decency from the White House – for instance, when he visited an old friend, former GOP Senate Majority Leader Bob Dole, after his recent cancer diagnosis.

No longer does the president of the United States spend his time attacking American democracy, waging personal feuds on Twitter or cratering painstakingly brokered political compromises in Congress.

As in the campaign, when his pandemic-enforced spell at his Delaware home made him an elusive political target, Biden’s rationed public appearances have made it tough for Republicans and the conservative media to line him up.

Washington journalists are complaining that the new President has yet to hold a formal news conference. But the strategy appears to be working. Perhaps because he is an old, White man, Biden is not the kind of lightning rod for right-wing radicals that former President Barack Obama was early on. Pro-Trump pundits have spent much of the last few weeks trying to whip up a storm over culture war issues like the supposed “cancellation” of children’s author Dr. Seuss. The White House has refused to take the bait.

Tough tests ahead

Early victories do not guarantee successful or ultimately popular presidencies. The job is so vast, and the challenges – from domestic security threats to a sudden foreign policy crisis – can be grave and unexpected. The pandemic, which destroyed the economy Trump had hoped to ride to reelection, is proof of that.

If Biden fails to get the immigration crisis under control, the success of passing the rescue plan may be quickly forgotten. White House press secretary Jen Psaki refused even to call the situation a “crisis” on Wednesday.

The President is also under extreme pressure on the issue of getting kids back to in-person classes now that he has secured billions of dollars for fixes, including improved ventilation in school buildings, for instance. While education is largely a state and local responsibility, the hardest problems reach the President – who gets the blame if he can’t fix them.

One of the most revealing aspects of the effort to pass the rescue plan was how powerful liberal figures such as Vermont’s Sen. Bernie Sanders embraced the bill as a monumental liberal reform. But progressives were disappointed that a hike in the federal minimum wage to $15 an hour was removed in the Senate, and the tensions between rival wings of the party are sure to resurface.

One crucial issue overshadowed by the race to vaccinate Americans and put them back to work is the unresolved threat to American democracy. Republican state legislators across the nation are rushing to suppress the potential vote of the 2022 midterm elections and the 2024 presidential election with new laws that often directly discriminate against minority and Democratic voters.

The For the People Act now awaiting attention in the Senate is meant to address such behavior and could be a defining moment for the US political system.

Given such tests, Biden’s objectively strong start to his presidency is only revealing the height of the political mountain up ahead.
