Joe Biden Given 8.5-Point Lead From Pollsters That Predicted Donald Trump's 2016 Win

Democratic presidential candidate Joe Biden has been given an 8.5-point by pollsters who said President Donald Trump would be victorious in the 2016 election.

Its results put Biden as being backed by 51.9 percent of respondents, compared to 43.4 percent for Trump.

In a head-to-head poll, discounting third-party candidates, Biden was 10.4 points in the lead, with 52.7 percent to Trump's 42.3 percent.

Splitting voters on gender, Trump was ahead with male voters but lagged with females.

Among males, 52 percent backed Trump compared to 44 percent for Biden. But with females, 59 percent back Biden compared to 36 percent for Trump.

The gulf between the pair has previously been described as a "gender chasm."

The polling was conducted among 851 likely voters from October 7 to 11.

The poll is described by IBD as "the most accurate presidential poll in America," and was one of the only two major polls to predict Trump defeating Hillary Clinton.

It is due to release daily updates through to November 3.

Newsweek has contacted the Trump and Biden campaigns for comment on the story.

Biden's lead coincides with the majority of national polling comparing him with Trump.

According to FiveThirtyEight's election tracker, he has an average lead of 10.5 points in national polling. Real Clear Politics' average gives him an advantage of 10.6 points. Both have been updated to include the IBD/TIPP results in their calculations.

As well as leading in national polling, Biden has also seen an advantage in a number of swing states. The Democrat also has been tipped to potentially spring upsets in some traditionally Republican-voting areas.

Trump lost the popular vote to Clinton last time out, but unexpected victories in several states saw him secure the Electoral College victory needed for his spot in the White House.

While the national polling last time out was generally fairly accurate in Clinton getting the most votes overall, the Electoral College system meant that securing a higher number in the popular vote did not guarantee her victory.

There have been suggestions that if Trump were to win re-election, it may be in a similar fashion of getting fewer votes overall, but by securing wins in states that secure him the Electoral College.

Trump has long dismissed polling, and on Sunday insisted he was heading for victory despite survey results suggesting otherwise.

He commented upon 2016 polling which he labeled a "disaster" and said: "Will have a bigger win than even 2016!"
