Polls Indicate Strong Lead for Alan Wilson

A recent InsiderAdvantage poll, conducted on June 19-20 among 800 likely Republican voters in South Carolina, suggests a commanding lead for Attorney General Alan Wilson in the state’s gubernatorial runoff. Wilson receives 61% support, while Lieutenant Governor Pamela Evette is at 29%. Another 10% of voters remain undecided.

This late shift toward Wilson could secure him the nomination in a low-turnout runoff, where even minor changes have significant impacts. Both Wilson and Evette have President Donald Trump’s endorsement, which shifts the focus to organizational strength and voter turnout rather than ideological differences.

Primary Race Developments

The runoff follows a tightly contested primary on June 9. With no candidate securing a majority, a second round between the top two finishers is necessary. Evette initially received 28.9% of the vote, narrowly ahead of Wilson’s 26.1%. However, support from Representatives Nancy Mace and Ralph Norman, who both failed to advance, strengthens Wilson’s position.

On the opposing side, Evette’s campaign, supported by outgoing Governor Henry McMaster, focuses on contrasting her as a “proven business leader” against Wilson’s political career. The campaign emphasizes continued outreach and the importance of voter turnout in the final days before Election Day.

Insights from the InsiderAdvantage Poll

The InsiderAdvantage poll, using a mixed-mode text and panel methodology, highlights a significant 32-point lead for Wilson over Evette. The survey’s margin of error is 3.46%. This lead suggests that voters whose preferred candidates were eliminated in the first round are largely rallying around Wilson. Despite Evette’s efforts, even a strong shift among undecided voters may not overcome Wilson’s advantage.

Earlier Polling Averages

Before the initial primary, surveys depicted a divided field with no front-runner. Various polling averages such as RealClearPolitics, Race to the White House, and FiftyPlusOne showed close margins between Evette and Wilson. The overall average indicated Evette at 19.6% and Wilson at 18.1%, reflecting the fragmented race dynamics.

Prediction Markets’ Sentiment

Prediction markets show a clear expectation of Wilson’s victory, pricing his chances above 98%. Platforms like Kalshi and Polymarket heavily favor Wilson, although each has limitations such as liquidity and demographic representation.

General Election Outlook

Looking ahead to the general election, experts widely consider South Carolina a solid Republican state. Forecasters from Inside Elections, RealClearPolitics, and Cook Political Report agree on this outlook. As the GOP primary concludes, the winner will likely enter the general election as a favorite against Democratic candidate Jermaine Johnson, who secured 59.7% of the primary vote.

Upcoming Runoff Vote

As South Carolina voters head to the polls from 7 a.m. to 7 p.m., the outcome hinges on voter turnout. While data suggests a likely victory for Wilson, the nature of low-turnout runoffs allows room for unexpected results driven by voter mobilization efforts.
