2020 South Carolina Primary Results and Information

2020 South Carolina Primary

This one is all about the 2020 South Carolina primary on the Democratic side.

South Carolina is in many ways the most important of the early states. It’s towards the end of the first wave of states before Super Tuesday and represents the time when the political men are separated from the boys, or women from the girls depending on who is running. By this point, there will have already been contests in the Midwest, the Northeast, and the West – the South is the last corner of America to chime in, and its effects are often heard loud and clear.

A poor result here means that perhaps a campaign does not stick it out until Super Tuesday, while a strong night in South Carolina may indicate momentum heading into that delegate-rich night.

Previous South Carolina Primary Results

We go as far back as the 1988 Democratic primary, and have excluded 1996 and 2012 as Bill Clinton and Barack Obama were not seriously challenged for their renominations.

Year Winner Nominee?
2016 Hillary Clinton Yes
2008 Barack Obama Yes
2004 John Edwards No
2000 Al Gore Yes
1992 Bill Clinton Yes
1988 Jesse Jackson No

More often than not in the last 30-plus years, South Carolina tends to pick the winners. Just Jesse Jackson and John Edwards won South Carolina but lost the nomination, with South Carolina in Jackson’s time coming much later in the process, after Super Tuesday.

2020 South Carolina Primary Counties to Watch

South Carolina most populous counties

Greenville County may have the most people of any county in the state, but keep in mind that they are in the deep-red northwestern corner of the state along I-85. A county like Richland County is probably as important, if not more important to a Democratic primary candidate. For one thing, Richland, home to the state capital Columbia, is perhaps the bluest county in South Carolina. There are also over 270,000 registered voters here, a majority of which are non-white, meaning many potential Democratic votes.2 Whichever candidate wins here is going to have a decent shot at the state as a whole with a vote divided a number of ways elsewhere.

For many of the same reasons, Charleston County in the Lowcountry will be critical. Charleston and its immediate suburbs are, for the most part, big and blue; Mount Pleasant to the east is a usual exception.

Horry County and Spartanburg County round out the top five in terms of population, but neither are hotbeds of Democratic support. One like Orangeburg County in the center of the state, south of Columbia, and another such as Sumter County, east of Columbia, may end up being important because of their extensive history of voting blue.

Who Needs A Big Performance in the South Carolina Primary?

No question, this is a very important primary to Joe Biden. Perhaps the former vice president is doing alright in other early states or maybe he is falling behind other top contenders, but this is the state he needs. His lead may not be what it was towards the end of 2019, but Biden needs to win this state and big to reset the race for the Democratic nomination. Biden has done very well in opinion polls with African-American voters in South Carolina3 and he needs them to turn out in large numbers on February 29. Depending on how he does in Iowa, New Hampshire, and Nevada (full calendar here), even a weak victory may be damaging to Biden’s candidacy.

Being one of the few African-American candidates in the race, it will be interesting to see what Cory Booker does, or does not do, in South Carolina. South Carolina is perhaps the only pre-Super Tuesday state in which Booker is poised for any sort of breakthrough. A poor showing here could spell the end for his campaign, even with Super Tuesday just a few days later.
