IMO, Kamala Harris will be the next POTUS, not only because of Allan Lichtman, but because of all the bad things trump said or did. For example, the obvious racism on the debate cast on TV for millions of people, when he said that haitien immigrates ate people’s pet in the Ohio. Also, Kamala Harris proved herself as a great politician on her time as VP of Joe Biden. I think that the poor performance of said Biden could impact people’s opinion of the Democrats, but i still think nevertheless that Kamala Harris will win.

Guessing will full accuracy who the next POTUS is near impossible, so it's up to every American citizen who's able to vote to do so
