Race to the White House: In debate countdown, Trump holds rally, Biden does prep

President Donald Trump shunned formal debate practice on Tuesday and was heading instead for another of his big rallies, two days ahead of the final presidential debate that may be his last, best chance to alter the trajectory of the 2020 campaign. Democrat Joe Biden took the opposite approach, holing up for debate prep.

In the lead-up to Thursday's face off in Nashville, Trump is trailing in polls in most battleground states as he works to pull off a repeat of his come-from-behind victory of 2016. Also trailing in fundraising for campaign ads, Trump is increasingly relying on his signature campaign rallies to deliver a closing message to voters and maximise turnout among his Republican base.

Three weeks of wrangling over the debate format and structure appeared to have subsided Tuesday after the Commission on Presidential Debates unveiled a rules change meant to reduce the chaotic interruptions that plagued the first Trump-Biden encounter last month.

This time, Trump and Biden will each have his microphone cut off while his rival delivers an opening two-minute answer to each of the six debate topics, the commission announced. The mute button won't figure in the open discussion portion of the debate.

Trump's team is calling for a more in-depth focus on foreign policy in the debate, believing it to be a strong suit for the incumbent, but there is not expected to be any shift away from the announced topics, which include a segment devoted to national security.

Trump was holding a rally Tuesday evening in Erie, Pennsylvania, a part of the state instrumental in his victory four years ago, when he was the first Republican candidate since Ronald Reagan to carry the county.

Erie County, which includes the aging industrial city in the state's northwest corner, went for President Barack Obama by five points in 2012 but broke for Trump by two in 2016. That swing, fueled by Trump's success with white, working-class, non-college-educated voters, was replicated in small cities and towns and rural areas and helped him overcome Hillary Clinton's victories in the state's big cities.

But Trump will likely need to run up the score by more this time around as his prospects have slipped since 2016 in vote-rich suburban Philadelphia, where he underperformed by past Republican measures. This raises the stakes for his campaign's more aggressive outreach to new rural and small-town voters across the industrial north.

His aides worry that his opponent is uniquely situated to prevent that, as Biden not only hails from Scranton, but has built his political persona as a representative of the middle and working class.

Vice President Mike Pence, meanwhile, was holding tele-rallies meant to boost vulnerable Republican Senate and House candidates, and he was leading a meeting of the White House coronavirus task force.

Trump was to have been joined in Erie by first lady Melania Trump, in what was to be her first public appearance since she and the president were sickened with Covid-19, but her chief of staff, Stephanie Grisham, said Tuesday that Mrs Trump has a lingering cough and would not accompany the president.

Before leaving the White House, Trump was taping an interview with CBS' 60 Minutes and a town hall with local news conglomerate Sinclair that will air on Wednesday.

Before the debate, the president was grumbling that he'd be at a disadvantage to his challenger.

"I just think it's very unfair," Trump told reporters aboard Air Force One as he returned from Arizona on Monday evening. "I will participate, but it's very unfair that they changed the topics and it's very unfair that, again, we have an anchor who's totally biased."

As Trump was on the road, Biden was huddling at his lakeside home in Wilmington, Delaware, with senior adviser Ron Klain, who is in charge of debate preparation. Also on hand: a group of aides that the campaign has purposely kept small to reduce the risk of spreading the coronavirus.

Biden, who taped his own interview with 60 Minutes on Monday at a theatre near his home, has no public events on Tuesday or Wednesday and wasn't scheduled to travel except to the debate itself on Thursday. His running mate, California Senator Kamala Harris was out campaigning, and he was expected to receive a late boost from former President Obama, who was to host an event Wednesday in Philadelphia.

Biden is now tested about every two days for the coronavirus and has never been found to be positive. He suggested before last week's planned second debate in Miami that the proceedings shouldn't happen if Trump was still testing positive for Covid-19 after contracting the virus earlier in the month.

The candidates instead held duelling town halls on separate networks after the commission said the debate should occur virtually, citing safety concerns, and Trump rejected the idea.

Biden has been tightlipped about his preparation for the Nashville debate, saying only that he has focused on watching Trump's past statements on key issues. Biden's advisers see the final debate as a chance to discuss foreign policy, which they, too, see as one of their candidate's strengths. Biden has praised the Trump administration for helping to broker deals that the Gulf states of Bahrain and the United Arab Emirates signed recognising Israel, but otherwise has accused the president of shunning allies and making foreign relations more volatile at most points around the globe.

The debate comes as Trump has used his closing message to voters to defend his handling of the coronavirus pandemic that has killed more than 220,000 Americans and to attack his Democratic rival for pledging to heed the advice of scientific experts.

Trump insisted Tuesday that he gets along with Dr Anthony Fauci, the government's top infectious disease specialist, while also complaining on Fox & Friends that the doctor who has clashed with him at times over the coronavirus is not a "team player".

A day earlier, Trump said on a call with campaign aides that "People are tired of hearing Fauci and all these idiots", adding of the doctor: "Every time he goes on television, there's always a bomb. But there's a bigger bomb if you fire him. But Fauci's a disaster."
