Either result in the US presidential election is going to be utterly remarkable. Kamala Harris could become the first woman to win the White House. Or Donald Trump could have pulled off the biggest political comeback in US history, having narrowly escaped an assassin’s bullet as well.

Harris became a late pick for the Democrats after President Joe Biden was forced out of the race by age and infirmity. Many Australians are still bewildered that Trump is even a candidate for the Republicans after he presided over four years of chaos and failed to accept his loss in 2020. This has become the most polarised US campaign of modern times, with large numbers of Republicans and Democrats voting not just for a president for the next four years, but in the belief they are saving America from either Marxism or fascism respectively. Experienced pollsters like Nate Silver have given up trying to predict the outcome.
