A professor with a track record in choosing the victor in US presidential contests has picked presumptive Democratic nominee Joe Biden to beat President Donald Trump in November’s polls. American University professor Allan Lichtman has correctly predicted every presidential winner since 1984, and chose Trump as the winner against former Secretary of State Hillary Clinton in 2016. He uses a system of 13 factors, which he calls “keys,” that determine victory. They include incumbency, whether there is a third-party candidate, the strength of the long-term and short-term economy, social unrest, scandals as well as candidates’ charisma.
