7news.com.au reports that one of Australia's leading American politics experts has found Joe Biden is leading the race for the White House but cautions against discounting Donald Trump. Professor Simon Jackman, the head of the University of Sydney's United States Studies Centre, released detailed polling analysis on Tuesday. "Polls currently indicate that Biden will win enough swing states to win the November election, but with no more than 65.1 per cent probability," states the report, co-authored by Zoe Meers.
