Who's In the Race

South Carolina's 3rd U.S. House District heads to a general election with three nominees on the ballot: Republican Sheri Biggs, Democrat Eunice Lehmacher, and Libertarian Brian Corriea.

Biggs, the incumbent, ran unopposed in her party's primary. Lehmacher won her party's primary on June 9, taking 53.4 percent of the vote over Ernest Mackins. Corriea was nominated at the Libertarian Party state convention.

What They Stand For

Sheri Biggs (Republican)

Biggs is a lieutenant colonel in the Air National Guard and a board-certified family nurse practitioner. Her campaign platform centers on five areas: border security, fiscal responsibility, abortion, gun rights, and veterans.

On immigration, Biggs calls for completing a border wall, ending "catch-and-release" policies in favor of deportation, and stopping the flow of illegal drugs across the border. Her congressional issues page argues that excessive government spending has fueled inflation and saddled future generations with unsustainable debt, and calls for accountability in the use of taxpayer dollars.

Biggs describes herself as pro-life, stating on her official House website that "life — born and unborn — deserves protection" and is "made in the image and likeness of God." On gun rights, she states that the Second Amendment "is guaranteed and shall not be infringed." Her veterans issues page states that America must ensure those who served receive "honor, dignity, respect, and care."

Eunice Lehmacher (Democrat)

Lehmacher is a licensed counselor and healthcare professional based in the Clemson area. Her platform, drawn from her campaign website and third-party aggregators citing her stated positions, focuses on healthcare costs, housing affordability, clean energy, inclusive governance, and campaign finance reform.

On healthcare, Lehmacher states that it is "a basic human need and human right" and that no one should be forced into bankruptcy by medical costs, according to localcandidates.org and civoren.com, which cite her stated positions. She also advocates for public investments to lower the cost of housing, groceries, and utilities, and supports cleaner energy and infrastructure spending.

Lehmacher has stated she plans to "make decisions on what helps the most people regardless of their race, religion, or immigration status," according to a Vote Common Good profile that quotes her directly. On campaign finance, she has pledged to accept no corporate PAC money and supports banning congressional stock trading, banning lobbying by former members of Congress, and overturning Citizens United, according to integrityindex.us.

Brian Corriea (Libertarian)

Corriea is a Navy veteran, homeschool parent, and political commentator based in Williamston, S.C. His campaign website states his campaign focuses on "limited government and individual liberty" and that he is running "with no campaign donations or strings attached."

His Libertarian Party national profile describes him as "dedicated to advancing the principles of individual liberty."

The Money Behind the Race

All recorded outside spending in this race supports the Republican candidate, with $6,356 in total independent expenditures directed toward Biggs. No opposition spending has been reported.

The sole outside spender on record is the Freedom Caucus Fund, which accounts for the full $6,356. The figures reflect Federal Election Commission filings through Sept. 21, with notices tracked through Sept. 28.
