Super Tuesday is the United States presidential primary election day in February or March when the greatest number of U.S. states hold primary elections and caucuses. It is an unofficial term used by journalists and political pundits to refer to presidential primary elections since at least 1976. Super Tuesday is the most important day on the Democratic primary calendar because there are so many delegates up for grabs. It is a popular day to hold a primary because so many states want an early say in who gets the nomination. Super Tuesday was born out of a desire by Democrats in the 1980s to nominate a more moderate candidate. The date of Super Tuesday varies from year to year, but it is usually held in early March. In 2020, Super Tuesday was held on March 3. Super Tuesday is important because it can be decisive and signal the end of a primary. Approximately one-third of all pledged delegates are doled out on Super Tuesday.
