Latest US election polls have Joe Biden leading Donald Trump

Four new polls show US Democratic nominee Joe Biden to have a significant national lead over current President Donald Trump as the November election approaches.

The poll results were released on Wednesday on the back of the US political party conventions, where the candidates have been attempting to gather support.

But despite Biden polling well, his lead appears to be dwindling.

A USA Today/Suffolk University poll found Biden leading Trump by seven percentage points (50-43 percent) among registered voters across the United States. This advantage was down from a 12 percentage point lead in the researcher's June poll.

The survey also found there is significant scepticism about whether the election can be trusted, with one in four voters saying they aren't prepared to accept the outcome as fair and accurate if their prefered candidate loses.

The latest poll from Quinnipiac University had Biden 10 percentage points ahead of Trump (52-42 percent).

Here's how those polled responded when asked who would do a better job at handling specific issues: 

  • On handling the economy, Biden and Trump equal 48-48 percent
  • On handling racial inequality, Biden would do a better job 58-36 percent
  • On handling the response to the coronavirus, Biden would do a better job 56-40 percent
  • On handling health care, Biden would do a better job 55-41 percent
  • On handling a crisis, Biden would do a better job 53-43 percent

Biden had an eight-percentage-point edge among likely voters in the Grinnell College/Selzer survey which was conducted on August 26-30.

The poll, which was released Wednesday, had Biden at 49 percent and Trump at 41 percent.

The survey also showed Biden had strong support among women, especially suburban women, Bloomberg reported.

He also did well with non-white voters and those who live in large metropolitan areas.

"Among suburban women, the President’s numbers are terrible," Peter Hanson, a political scientist at Grinnell College who directed the poll, told The Hill. 

"If the President's coalition is going to consist of non-college-educated white men, evangelicals and seniors, then he's going to have a hard time."

Hanson told Bloomberg Trump's most likely path to victory is to repeat what he did in 2016: "Win the Electoral College with narrow victories in battleground states despite losing the national popular vote."

The results of the Grinnell College/Selzer survey were echoed in a CNN poll of registered voters that also gave Biden an eight-percentage-point lead.

The poll was conducted between August 28 to September 1 and had Biden on 51 percent and 43 percent backing Trump.

But despite the poll results, the New York Times has reported the election is most likely to be won and lost in just a few key swing states.

"Even if Mr Biden ekes out a narrow win in the popular vote, he could still lose the Electoral College, as Hillary Clinton did in 2016," they reported.

Trump and Biden are now both travelling to Pennsylvania next week to commemorate the anniversary for the September 11 attacks.
