Trump would talk improptu to a hostile media for 15 to 30 minutes on his way to Marine One Chopper on the White House Lawn. Joe Biden can not.
I actually think Biden knew what questions would be asked. They would ask him a question and he would hesitate, look down with his eyes partially closed as if trying to remember the answer to the question that he was supposed to know. If he could not remember he would then answer as best he could and screw up sentences, facts, grammar and syntax. He is a mental mess.
Between now and inauguration day is a very dangerous time for the United States. Biden, if the military obeys, can start a nuclear war. There are no winners in that war!
