Between his body language, lack of knowledge, and trying to turn it into the dung fight in the primate cage, that did it for me. I will never vote for Trump. His behavior in the first 15 minutes alone only confirmed for me what I thought about him. He needs to pick up an American history book pre-1960, U.S. Government pre-1960, and a Copy of The Constitution of the United States and read them all starting with the Constitution. Then he needs some world history and current events. Maybe in a decade he would be up to speed with the others there last night knowledge wise.
It’s not enough to know stuff. A president also has to be able to do stuff, and to lead. Trump is accustomed to having many good people working for him whose job it is to know specialized areas in depth. They keep him informed with relevant information reports; his key people outline the issues on the overall agenda and develop scenarios for handling issues, and ultimately the boss sets the direction and reviews progress and results. Many, many good ideas are lost for want of good and timely execution.
