The presidency of George W. Bush began at noon EST on January 20, 2001, when George W. Bush was inaugurated as the 43rd president of the United States, and ended on January 20, 2009. By the end of election night, Florida emerged as the key state in the election, as whichever candidate won the state would win the presidency. Bush held an extremely narrow lead in the vote by the end of election night, triggering an automatic recount.
