Super Tuesday is unfortunately not a big holiday sale, but instead refers to a Tuesday, sometime in February or March, of a presidential election year when the greatest number of states hold primary elections to select delegates to national conventions. Candidates seeking their party’s nomination hope to win the most states on Super Tuesday.
Super Tuesday is important because these primaries compare the electability of each candidate and who is more appealing to a broader constituency.
The map below shows which states participated in Super Tuesday in the 2008 Presidential Election. Blue denotes Democratic-only caucuses. Red is Republican-only and Purple indicates elections for both parties.
