Super Tuesday (2008)

Super Tuesday 2008, Super Duper Tuesday,Mega Tuesday,Giga Tuesday,Tsunami Tuesday, and The Tuesday of Destiny are names for February 5, 2008, the day on which the largest simultaneous number of state U.S. presidential primary elections in the history of U.S. primaries were held. Twenty-four states and American Samoa^¤ held either caucuses or primary elections for one or both parties on this date. Furthermore, the week-long Democrats Abroad Global Primary began on this day.

The large number of states that held elections on February 5 could have shortened the period between the first caucus in Iowa, on January 3, 2008, and the de facto selection of a party's nominee to just a few weeks. Super Tuesday 2008 saw 52% of the Democratic and 41% of the Republican delegates awarded by early February 2008. By comparison, only about 1% of nominating convention delegates had been selected by that point in the 2000 election cycle. It was held approximately one month before Super Tuesday II.

The name "Super Duper Tuesday" is a reference to earlier Super Tuesdays, the dates on which the largest number of presidential primaries took place. The term "Super Duper Tuesday" has been repeatedly re-coined to refer to even more states holding their primaries on this date, with the first recorded usage so far found dating back to 1985. In 2004, Super Tuesday fell on March 2. In 2004, the equivalent cohort of primaries, on February 3, 2004, was called "Mini-Tuesday"—only seven states held their primaries on that date.

On June 3, 2007, the name "Tsunami Tuesday"—conveying the potential of the large number of simultaneous primaries to completely change the political landscape—was mentioned on Meet the Press during a round-table discussion with presidential campaign strategists James Carville, Bob Shrum, Mary Matalin, and Mike Murphy.
