Poll: Biden Leading Trump by Eight Points

The July 15-21 poll found that 46 percent of registered voters said they would back Biden in the Nov. 3 election, while 38 percent would vote for Republican Trump. The remaining 16 percent are either undecided, plan to support a third-party candidate or may not vote.

Both Biden and Trump campaigns have focused much of their time on reaching out to this third group of potentially persuadable voters, which could swing a close election in either direction.

Reuters/Ipsos polling in 2016 found that support was evenly split that summer between Trump and then Democratic nominee Hillary Clinton among registered voters who had not backed a major party candidate. On Election Day, Trump won a majority of voters who said they decided in the final week.

This year, the poll found that 61 percent of undecided or third-party registered voters said they would support Biden if they had to choose, while 39 percent would vote for Trump.

Seventy percent of undecided or third-party registered voters say they disapprove of Trump's performance in office and the same number said they think the country is headed on the wrong track. And 62 percent said they thought the US economy was headed in the wrong direction.

This group also appears to be deeply concerned about the novel coronavirus, which has killed more than 141,000 Americans and forced millions out of work as businesses closed in an effort to slow the spread of the virus.

About 8 in 10 said they were personally concerned about the spread of the virus. When asked about the most important factor driving their decision to vote, 34 percent - a plurality - said they were looking for a candidate who has "a robust plan to help the nation recover."

Another 24 percent said they were looking for someone who can "restore trust in American government" and 12 percent said they wanted a candidate who is "strong on healthcare."

Registered voters have consistently ranked Biden as the better candidate when it comes to all three.

The Reuters/Ipsos poll also showed that only 38 percent of the public supports Trump's handling of the coronavirus, including 20 percent of undecided or third-party registered voters.

Trump, who played down the crisis and did not appear publicly in a mask until July 12, pushed to reopen businesses well before health experts said it was safe.

Trump appeared to shift his tone this week and restarted regular briefings on the pandemic Tuesday, encouraging Americans to wear a face covering if they could not keep socially distant.

The Reuters/Ipsos poll was conducted online, in English, throughout the United States. It gathered responses from 4,430 American adults, including 3,744 registered voters, and 595 registered voters who had not supported a major-party candidate.

It has a credibility interval, a measure of precision, of about two percentage points for the entire group and five points for the undecided or third-party voters.
