Bloomberg served as the 108th Mayor of New York City, holding office for three consecutive terms, beginning with his first election in 2001. A Democrat before seeking elective office, Bloomberg switched his party registration in 2001 to run for mayor as a Republican. He defeated opponent Mark Green in a close election held just weeks after the September 11 terrorist attacks. He won a second term in 2005, and left the Republican Party two years later. Bloomberg campaigned to change the city\'s term limits law, and was elected to his third term in 2009 as an Independent candidate on the Republican ballot line. In 2018, citing the need for Democrats to restore America\'s system of checks and balances, Bloomberg re-registered as a Democrat.\n', '
