With just two days left for the November 3 US presidential election, Democratic nominee Joe Biden was in the lead against President Donald Trump by eight points nationally, according to a new poll.

The Fox News poll released on Friday revealed that 52 per cent of likely voters backed the former Vice President, while Trump had the backing of 44 per cent. Two per cent of those surveyed say they would back a third-party candidate, while another 2 per cent remained undecided. Other surveys have also showed Biden leading the President in key swing states.
