Super Tuesday
In 2000, Super Tuesday was on March 7. Sixteen states held primaries on Super Tuesday, the largest presidential primary election day in U.S. history up to that point. Approximately 81% of Democratic delegates and 18% of Republican delegates needed to secure nomination were up for grabs. Democrat Al Gore and Republican George W. Bush cemented their nomination bids with Super Tuesday victories, and both went on to win their parties' nominations.
