We're now just over two months from the US Presidential Election; although many will soon start voting with the use of absentee ballots likely to be extensive due to Covid-19.
Trump is going to try to use every legal and semi-legal trick to win - if he loses, he will claim voter fraud. He was even claiming it after he won, stating that he had actually won the popular vote when he didn't.
Biden is in a better position than Clinton was at this point with a significant lead. Trump is the worst position for an incumbent in decades and it could well get worse for him. He could somehow eke out a win, but I doubt it.
In any event, it's likely to be messy in US politics for quite a while.
