Twenty-four states are holding caucuses or primary elections on Super Tuesday, 2008. Blue denotes Democratic-only caucuses (3), Red illustrates Republican-only contests (2), and Purple represents states holding elections for both parties (19).
More delegates can be won on Super Tuesday than on any other single day of the primary calendar, and accordingly, candidates seeking the presidency traditionally must do well on this day to secure their party's nomination.
In 2008, Super Tuesday was February 5; 24 states held primaries or caucuses on this date, with 52 percent of all pledged Democratic Party delegates and 41 percent of the total Republican Party delegates at stake.
