WASHINGTON — President Donald Trump and his adversaries mobilized Sunday (20) for an epic campaign-season showdown over the future of the Supreme Court even as the nation prepared to honour the life of Justice Ruth Bader Ginsburg in an outdoor viewing to be held according to pandemic-era guidelines.

The president’s determination to confirm a replacement for Ginsburg before the November 3 election set lawmakers on a collision course with one another at a time when Congress already has major issues on its agenda, including spending bills to keep the government open past next week and a stalled coronavirus relief package to help millions of Americans left unemployed by the pandemic that has killed nearly 200,000 people in the United States.

Undaunted by the prospect of such a volatile fall, Trump prepared to announce a nominee as early as Tuesday in hopes of pressuring the Senate to ratify his choice before voters decide whether to give him a second term and spoke multiple times with Sen. Mitch McConnell, the majority leader. Even as a moderate Republican senator reaffirmed her opposition to such an accelerated timetable Sunday, others like Sen. Lamar Alexander of Tennessee fell in line and it appeared increasingly likely that Trump may get the votes to proceed, although there were a few holdouts still to be heard from.

The political manoeuvring took place even as the nation was mourning Ginsburg, a champion of women’s rights and a hero to the left who died at age 87 Friday night. Admirers continued to flock to the Supreme Court building, where they left flowers, candles, signs, newspaper front pages and pictures of the woman who late in life came to be called the Notorious RBG by her fans.

The justice may lie in repose at the court for two days, with a ceremony there as early as Tuesday (22) followed by an outdoor viewing, leaving unclear whether the president would wait to announce his chosen replacement until afterward. Ginsburg’s death unleashed a wave of fundraising by both parties, particularly among liberals, who poured forth $100 million through ActBlue, the donation-processing site, by noon Sunday. Trump’s campaign began selling ‘Fill That Seat’ T-shirts based on a chant at the president’s campaign rally Saturday (19) night.

Former Vice President Joe Biden, the Democratic presidential challenger, on Sunday denounced Trump’s decision to move ahead with a nomination and appealed to the handful of moderate Senate Republicans to stop the president from making a lifetime appointment that would shift the balance of power on the nation’s highest court without waiting to see the results of the election.

“To jam this nomination through the Senate is just an exercise in raw political power,” Biden said in a speech in Philadelphia, noting that Republicans refused to even consider President Barack Obama’s nominee after Justice Antonin Scalia died in February 2016, citing the coming election. “I don’t believe the people of this nation will stand for it. President Trump has already made it clear this is about power, pure and simple.”

If Trump wins the race, Biden added, then the Senate should consider his choice. “But if I win the election, President Trump’s nomination should be withdrawn,” said Biden, who has promised to make his first appointment to the Supreme Court an African American woman to the Supreme Court. “As the new president, I should be the one who nominates Justice Ginsburg’s successor, a nominee who should get a fair hearing in the Senate before a confirmation vote.”

A new poll showed that the American public agrees with him and opposes Trump’s plan to rush a new justice onto the court. Of those surveyed by Reuters and Ipsos since Ginsburg’s death, 62% said her seat should be filled by the winner of the November election, including the vast majority of Democrats and even half of Republicans.

One reason Trump may feel differently is the possibility that he may not be that winner. Biden has consistently led the president in polls for months, and a new survey released Sunday by NBC News and The Wall Street Journal found the Democrat’s lead stable at 51% to 43%, essentially unchanged since before the two parties’ nominating conventions. Trump’s focus on law and order in recent weeks has not changed the overall dynamics of the race, and 9 in 10 of those surveyed said their minds were firmly made up.

The White House hopes that a Supreme Court fight will make a difference when everything until now has not, giving Republican voters who care about the courts, particularly those opposed to legal abortion, a reason to turn out for him despite any concerns about his handling of the coronavirus, the state of the economy or other issues.

“Trump needed a circuit-breaking event to change the dynamic of the race, which has clearly favoured Biden so far,” said Douglas B. Sosnik, who was President Bill Clinton’s White House political director during his 1996 re-election campaign. “Up until now, the election has largely been about the impact of the coronavirus on the health of the public and of the economy, and any day that’s the focus is a bad day for Trump.”

Trump vowed at his campaign rally Saturday night to pick a woman, and people informed about the process said Sunday that he was considering Judge Amy Coney Barrett of the 7th US Circuit Court of Appeals in Chicago, Judge Barbara Lagoa of the 11th Circuit in Atlanta and Kate Todd, a deputy White House counsel.

McConnell has committed to holding a vote on Trump’s forthcoming nominee, but not to any particular time frame and in theory could wait for the lame-duck session after the election. McConnell planned  to meet with his leadership team Monday  (21) and with the whole Republican conference Tuesday.

Sen. Lisa Murkowski, R-Alaska, confirmed Sunday what she had said before Ginsburg’s death, that she opposed a vote so close to the election. “I did not support taking up a nomination eight months before the 2016 election to fill the vacancy created by the passing of Justice Scalia,” she said. “We are now even closer to the 2020 election — less than two months out — and I believe the same standard must apply.”

But many Republicans who four years ago blocked Judge Merrick B. Garland, Obama’s choice to replace Scalia, indicated that they had no problem going ahead with Trump’s selection, saying the difference now was that the president and the Senate majority were from the same party.

“No one should be surprised that a Republican Senate majority would vote on a Republican president’s Supreme Court nomination, even during a presidential election year,” Alexander said in a statement Sunday. “The Constitution gives senators the power to do it. The voters who elected them expect it.”

“Sen. McConnell is only doing what Democrat leaders have said they would do if the shoe were on the other foot,” he added.

A number of other Republicans who were seen as possible objectors to a pre-election confirmation have also indicated they will support one, including most prominently Sen. Lindsey Graham of South Carolina, chair of the Senate Judiciary Committee, who previously vowed to do the exact opposite if a vacancy occurred in the last year of Trump’s term.

Still silent Sunday, however, were a handful of Republicans who could in theory join Murkowski and Sen. Susan Collins of Maine in blocking a quick vote: Sens. Mitt Romney of Utah, Cory Gardner of Colorado and Charles E. Grassley of Iowa. With a 53-47 majority and Vice President Mike Pence to break ties, McConnell could afford to lose only one of them.

The average Supreme Court confirmation takes about 70 days from the nomination, and it was not clear how the Senate would proceed with just 42 days as of Tuesday, especially with annual spending bills and the coronavirus relief package still to be addressed. House Speaker Nancy Pelosi said Sunday that Democrats had ways to obstruct the process.

“We have our options,” she said on “This Week” on ABC. “We have arrows in our quiver that I’m not about to discuss right now, but the fact is we have a big challenge in our country.”
