My single insight is that when McCain responds to a question, he responds from the position of the isolated ego -- "I did such & such. . ." -- whereas Obama responds as a member of a group -- "we must do. . . such & such." McCain wants to be president because it will fulfill his personal ambitions; Obama wants to be president in order to accomplish things beyond himself. McCain responds with anecdotes about his personal experience, telling us that he has been to Russia, or Pakistan; Obama responds with an analysis on which to base his proposed actions.
