I predict Joe Biden will not seek a second term. He'll be 82-83 years old. So it will be wide open with Kamala, of course, signing up to run.
Trump will be 79 years old and will be demonstrating far more irrational and demented behavior than he his now. Next three years all the legal charges against him and the indictment of Trump Org and likely Donald and Ivanka along with it will come to fruition, plus the charges filed against him in Georgia for election interference will probably keep Mar A Lago Fats on the sidelines.
