2004
In 2004, several states moved their presidential contests up to February 3, 2004 in order to increase the relative importance of their election results. Ultimately, five states held primaries and two held caucuses on this date, a date eventually christened Mini-Tuesday or, alternatively, Super Tuesday I by pundits, with the traditional March Super Tuesday date, March 2, christened Super Tuesday II, or just simply "Super Tuesday." Arguably, the Roman numeraled names are most consistent with how Super Tuesdays were first christened in 1984, when there were in fact three Super Tuesdays.
