WASHINGTON - With several polls showing Democratic presumptive nominee Joe Biden leading the U.S. presidential race nationally, in battleground states and among key demographics, President Donald Trump’s campaign is seeking a more effective strategy to win over voters.

After spending weeks pushing to reopen the economy, the president now appears to be acknowledging the coronavirus pandemic will continue to drive news cycles through the final 100 days of the campaign.

Key Takeaways from Trump’s Evolving Campaign Strategy

Here are a few key takeaways from Trump’s evolving re-election strategy.

Polls indicate that public approval for the of the COVID-19 pandemic is falling to a new low — with just around one third of Americans supporting his approach which emphasizes reopening.

In the past two weeks, the president has returned to making regular appearances before journalists, putting himself forward as spokesperson for his administration’s response to the pandemic.

The president has canceled the Republican National Convention in Jacksonville, Florida, because of the growing COVID-19 outbreak there. He also acknowledged that some schools may need to delay their reopening, and has recommended Americans wear masks in public.

Republican strategists say it’s an admission that the president has few options but to refocus his attention on the pandemic.

“It's really difficult as a campaign to focus on a message when there's nothing else you can talk about than what is on the minds of really of everybody in America,” said Chris Wilson, CEO of WPA Intelligence in an interview.

Staying “on message” is how politicians traditionally have helped build support for their causes, but Trump has long had a more freewheeling political style. On Monday this week he returned to his emphasis on ending the lockdowns in some states.

“I really do believe a lot of the governors should be opening up states that are not opening,” Trump said during a visit to a vaccine development facility in North Carolina. “We’ll see what happens with them.”

By Thursday, he again appeared to have reversed himself on the severity of the pandemic.

He suggested that the November elections should be delayed to ensure people can safely vote in person, even though the Constitution allows only Congress to schedule elections. Republican and Democratic Congressional leaders rejected the suggestion and vowed the election will be held as scheduled.

Both Trump and Vice President Mike Pence visited vaccine development facilities this week as the White House pressed its message that the nation is close to defeating COVID-19.

During a coronavirus press briefing on Wednesday, Trump said the U.S. is on track to “rapidly produce” 100 million doses as soon as a vaccine is approved “which could be very, very soon.” He said 500 million doses will be available “shortly thereafter.”

There are currently more than 100 scientific groups around the world trying to make vaccines, including Pfizer and BioNTech which have started large-scale trials in the United States. But most experts agree that having a safe and reliable vaccine available before the November election is unlikely.

“There is progress on a number of fronts,” said William Schaffner, professor of infectious diseases at the Vanderbilt University Medical Center. “We're optimistic, but everything has to go well in vaccine development.”

While a vaccine is under development, the president is still pushing other treatments aimed at reducing the severity of COVID-19. This week he again championed hydroxychloroquine — an anti-malaria drug that Trump and his allies have been pushing as a COVID-19 treatment.

So far there is no evidence that hydroxychloroquine helps to prevent COVID-19 infection, said former Food and Drug Associate Commissioner and co-founder of the Center for Medicine in the Public Interest, Peter Pitts. However Pitts told VOA recent studies have shown that it may help shorten hospital time for patients who suffer from serious manifestations of the virus.

Analysts say that Trump advisers see messaging on vaccines and therapeutics as the quickest way to restore confidence in the president.

“The plan is to present certain drugs that are unproven as useful therapeutics until they have a vaccine,” said Larry Sabato from the University of Virginia’s Center for Politics to VOA.

Sabato said the lack of scientific data to support the claim is immaterial. “For Trump supporters, he is their source of information.”
