James Buchanan

Origins
James Buchanan had no father and his mother died during childbirth, leaving him alone through his whole life. Because of this, he never developed any social skills, and was completely unprepared when he found a city to live in at age 60. One day he decided to face his fears of basic interaction and run for president, and won because even though he could barely speak, he was still easier to understand than Franklin Pierce. Also, because he never talked to people, he became a president with a Mohawk because nobody told him how stupid it looked.

Presidency
James Buchanan devoted himself to preventing a civil war, but completely failed because he couldn't convince the south due to his lack of social skills. Any compromise he tried to make was easily overrun by the south, and they declared their independence. Due to his failures, he was not reelected. He died later when he couldn't talk to a mugger.
