I spent several years in a North Vietnamese prison camp in the dark, fed with scraps. Do you think I want to do that all over again as vice president of the United States? The vice president has two duties. One is to break a tie in case of a tie vote in the United States Senate... The other is to inquire daily as to the health of the president. Neither one of those are very challenging as compared to being able to live for a good part of the time in the state of Arizona.
