You’ve probably seen the headlines. South Carolina is "deep red." It’s a foregone conclusion. Why even bother looking at the data, right? Honestly, that’s where most people stop, and it's exactly where they start getting things wrong. While the final results of the 2024 election didn't necessarily shock the world, the story told by the south carolina polls 2024 throughout the year was way more nuanced than a simple "red state" label suggests.
The numbers shifted. The ground moved.
If you just look at the 58.2% to 40.4% split between Donald Trump and Kamala Harris in the general election, you miss the absolute dogfight that happened during the primary season. You miss the record-breaking early voting numbers. Most importantly, you miss how specific regions like Charleston and Richland started pulling in a completely different direction than the rest of the Palmetto State.
The Primary Chaos No One Expected to Last
Early in the year, everyone was obsessed with the Republican primary. It was personal. You had a former governor, Nikki Haley, going head-to-head with the man who once appointed her to the UN.
Polls from Winthrop University and Emerson College were flying out every week. In February 2024, the Winthrop Poll showed Trump with a massive 36-point lead among likely voters. People thought Haley would have a "home-court advantage," but the data said otherwise. Trump eventually took the primary with about 59.8% of the vote.
Haley didn't just disappear, though. She managed to snag nearly 40% of the vote. That’s not a small number. It signaled a real, measurable "Never Trump" or "Haley Republican" contingent in places like the 1st Congressional District.
On the other side, Joe Biden basically cruised. He cleared 96% in the Democratic primary. But low turnout—only about 4% of registered voters—had pundits worried. Was the "First in the Nation" status for the South Carolina Democrats actually driving engagement, or was it just a quiet formality?

Why South Carolina Polls 2024 Kept Shifting
Once the matchup flipped from Biden to Harris, the south carolina polls 2024 started showing some weird flickers of life for the Democrats.
A Winthrop Poll from late September 2024 had Trump at 52% and Harris at 42%. Now, a 10-point gap is still a mountain to climb, but compare that to 2020, where Trump won by nearly 12 points. Harris was actually outperforming Biden’s 2020 pace in several key demographics.
The Great Demographic Divide
It basically comes down to where you live. If you’re in Horry County or the Upstate, it’s Trump country. Pure and simple. Trump walked away with over 68% in Horry.
But look at the "blue islands":
- Richland County: Harris 66.4%
- Charleston County: Harris 51.9%
- Orangeburg County: Harris 61.8%
The polls largely predicted this split, but they struggled to capture the sheer volume of people who showed up early. South Carolina saw more than 2.5 million voters cast a ballot. That’s a record. Over 1.47 million of those people didn't even wait for Election Day—they used the new early voting process.
What the Pollsters Actually Missed
Kinda funny how we rely on these numbers so much, yet they often miss the "vibe shift." Polls often struggle with "unfiltered" voters—people who don't answer unknown calls or participate in online panels.
In South Carolina, there was a massive gap in enthusiasm. Trump’s base was locked in. The polls showed it early: 51% of South Carolinians in a September poll thought Trump’s legal convictions were purely political. That kind of baked-in loyalty is hard for a challenger to break, no matter how much money is spent on ads in the Greenville-Spartanburg market.
Also, the "undecided" factor was a bit of a myth. By October, ActiVote and other trackers showed only about 4-6% of voters were truly on the fence. Most people had picked their "team" long before the first leaf fell in the Lowcountry.
Actionable Insights for the Future
If you're looking at South Carolina and wondering if it'll ever flip, or how to read these polls better next time, keep these three things in mind:
- Watch the Margins in Charleston: This is the bellwether. If a Democrat can't win Charleston by double digits, they can't win the state. In 2024, the margin was about 6 points. That's the number to beat.
- Early Voting is the New Standard: Don't wait for Election Day polls. The "Early Vote" data in SC is now the most accurate reflection of the final result.
- Primary Data Matters: The 40% Haley got in the primary didn't all go to Trump in the general. Some stayed home; some flipped. Understanding that "moderate" Republican block is the only way to predict future swings in the 1st and 2nd districts.
The south carolina polls 2024 proved that while the state is reliably Republican, the "Solid Red" wall has some very interesting cracks in the urban centers.
To stay ahead for 2026 and 2028, stop looking at statewide averages. Start looking at the growth in Berkeley and Dorchester counties. That's where the next decade of South Carolina politics will be decided.
