Yeah. he really needs to have the fire in his belly that Reagan had. He was now weak, but meek (strength under control) and he didn't mind humorous replies to comments by his opponent that showed their weaknesses. He was able to emphasize his age humorously, putting the viewers at ease, and helping them to relax their attitudes. Self-deprecating humor goes hand in hand with humorously defeating your opponent, no one has to be mean spirited, but you have to know your opponent's weak spots and shine a spotlight on them. Make him get mad while retaining dignity.
