My great grandfather's joke was always "There's only one man I'd vote for, and I won't run." The office attracts people who are there for the wrong reasons, with Carter being the exception that proves the rule.

To summarize the summary: anyone who is capable of getting themselves made President should on no account be allowed to do the job."
