The phrase "Super Tuesday" first emerged in 1980, when three Southern states — Alabama, Florida and Georgia — held their primaries on the same day.
It grew to nine in 1984. But the modern-day Super Tuesday was born in 1988, when a dozen Southern states on the Democratic side, upset with the nomination of Walter Mondale four years earlier and frustrated with being out of power in the White House for 20 years save for one term of Jimmy Carter, banded together to try to nominate someone more moderate.
Al Gore of Tennessee and Jesse Jackson split the Southern states with Jackson winning black Democrats.
That allowed for Massachusetts Gov. Michael Dukakis to become the nominee after winning in the North, as well as in Florida and Texas. He, like Mondale before him, would go on to lose badly in the general election.
Ironically, the more moderate, Southern white Democrats, who concocted the Super Tuesday plan, are now rare in the modern Democratic Party.
And the Southern states remain big players on Super Tuesday, giving more influence not to moderate whites but to black voters. In seven of those Southern states, for example, a third of the Democratic electorate in 2008 was African-American. In two of them — Georgia and Alabama — they were a majority of Democratic voters.
On the Republican side in 1988, Super Tuesday worked for George H.W. Bush. He won 16 of the 17 contests that year, helping to clinch the nomination. It also sealed the nominations for Democrat Bill Clinton in 1992, Republican Bob Dole in 1996 and Republican George W. Bush and Democrat Al Gore in 2000, as well as Democrat John Kerry in 2004.
Outside of the 1988 and 2008 Democratic races, Super Tuesday had essentially brought the nomination fights to an end, and it had done so in every GOP race — until 2008 and 2012.
While the nominations weren't quite wrapped up those years for John McCain and Mitt Romney, respectively, they still won their Super Tuesdays, and it gave them clear front-runner statuses. They did go on to the GOP nomination after somewhat drawn-out fights.
