On March 13, 1984, the first official Super Tuesday was held with nine states, American Samoa and Democrats abroad participating. The nine states that participated were Alabama, Florida, Georgia, Hawaii, Massachusetts, Nevada, Oklahoma, Rhode Island and Washington. Gary Hart won six states (Florida, Massachusetts, Nevada, Oklahoma, Rhode Island and Washington) and Walter Mondale won three states (Alabama, Georgia and Hawaii) and American Samoa. On Super Tuesday in 1984, 512 delegates, 13 percent of the total number of delegates, were chosen.

In 1988, the last time Al Gore ran for president, he won only six of the 21 Super Tuesday states: Arkansas, Kentucky, Nevada, North Carolina, Oklahoma and Tennessee. Michael Dukakis won eight states (Florida, Hawaii, Idaho, Maryland, Massachusetts, Rhode Island, Texas and Washington) and American Samoa; Jesse Jackson won five states (Alabama, Georgia, Louisiana, Mississippi and Virginia); and Dick Gephardt won Missouri.

On the Republican side, George Bush won 16 out of 17 of the 1988 Super Tuesday primaries and caucuses - he lost the Washington Caucus to Pat Robertson and Bob Dole. That year, 753 delegates, or 33.3 percent of the total number of delegates, were chosen on Super Tuesday.

Bush swept all eight Super Tuesday Republican primaries in 1992. That year, 421 delegates, 19.1 percent of the total number of delegates, were chosen on Super Tuesday.

In 1992, Bill Clinton won nine out of 11 Super Tuesday primaries and caucuses (Florida, Hawaii, Louisiana, Mississippi, Missouri, Oklahoma, Rhode Island, Tennessee and Texas). Paul Tsongas won Delaware and Massachusetts. On Super Tuesday in 1992, 783 delegates, 18.3 percent of the total number of delegates, were chosen.

In 1996, Bob Dole swept all 10 Super Tuesday primaries and caucuses; 268 delegates, 13.5 percent of the total number of delegates, were chosen that day.

The last time a candidate, in a seriously contested race, swept all the primaries was John F. Kennedy in 1960. Kennedy only entered seven primaries, but he won them all (Wisconsin was closer than expected against Hubert Humphrey but Kennedy won with 56 percent).
