The absence of a large partisan gap on the issue is particularly striking, said Bob Blendon, a professor of health policy and political analysis at the Harvard T.H. Chan School of Public Health who designed the poll.
“Usually, our polls find a big split between Republicans and Democrats, so this is unique,” he said. “More conservative media have been carrying the ‘lab leak’ issue, and it’s been a Trump talking point from the beginning, so we expected people who lean Democratic would say either ‘It’s not true’ or ‘I don’t know.’ But the belief is bipartisan.”
Blendon said Democrats likely became more receptive to the idea after President Joe Biden’s recent order that intelligence agencies investigate the virus’ origin and comments from Anthony Fauci, the White House chief medical officer, that it’s worth digging into. Fauci and other scientists have cautioned the answer may never be known definitively.
“That the president thought there was enough evidence to ask intelligence agencies to put together a report sends a signal to Democrats that there might be something there,” Blendon said.
Democratic lawmakers have also faced pressure to look more closely at the lab leak scenario, though they worry Republicans will stoke uncertainty about the virus origin for political gain. Several congressional committees have launched inquiries, and the House Science Committee plans to hold its first hearing on the issue next week.
The POLITICO-Harvard poll, which will be released next week, also found there’s a high level of public interest in investigating Covid-19’s origin, with almost two-thirds of Democrats and Republicans calling the issue “extremely” or “very” important. The finding also surprised Blendon, who said the public isn’t typically invested in such a scientific inquiry.
The broad attention on the issue underscores the stakes for the Biden administration’s upcoming report on the virus origin, due in August. Even if the report concludes the virus came from nature, it could be hard to move public opinion, lawmakers and researchers like Blendon have noted.
The poll surveyed 1,009 adults from June 22-27. The margin of error was plus or minus 3.8 percentage points.
