If anyone need to study for anything evolving presidency here are some facts Fact #1: In 1801, Thomas Jefferson decided to walk to his inauguration to show how down-to-earth he was. He thought his predecessors had been too showy, and he wanted to show “Republican simplicity.” He wore clothes “of a plain citizen without any distinctive badge of office.” Fact #2: As mentioned above, Adams chose not to attend the inauguration of Jefferson. Hours before the ceremony, Adams left Washington to head back to his home in Massachusetts. This made Adams the first president to skip his successor’s swearing in. (Adams and Jefferson eventually reconciled and over the last 15 years of their lives, the two ex-presidents exchanged over 150 letters.)Fact #3: John Quincy Adams (the son of John Adams) boycotted Andrew Jackson’s inauguration on March 4, 1829.Fact #4: In 1849, Inauguration Day fell on a Sunday. Zachary Taylor refused to be sworn in on that day because he was strict about “keeping holy the Sabbath.” Since the office of the president could not be empty even for a day (the Constitution doesn’t allow it), president pro tempore of the Senate, David Rice Atchison was brought in to substitute. Some argue this makes Atchison the 12th president of the United States and Taylor is the 13th. Most people do not include Atchison in the count though. The inscription on Atchison’s headstone humorously states “President of the United States for One Day.”
