A primary election is an election in which registered voters select a candidate that they believe should be a political party's candidate for elected office to run in the general election. They are also used to choose convention delegates and party leaders. Primaries are state-level and local-level elections that take place prior to a general election. South Carolina utilizes an open primary system, in which registered voters do not have to be members of a party to vote in that party's primary. Voters must take an oath affirming that they have not voted in another party's primary.[1]
For information about which offices are nominated via primary election, see this article.

Submitted Biography: "I’m Mac Deford, a U.S. Coast Guard veteran, attorney, and part of a new generation of leadership in the Lowcountry. I enlisted at 18 in the U.S. Coast Guard, learning firsthand what integrity, service, and accountability truly mean. After earning my law degree, I advised some of South Carolina’s top municipalities, helping guide them through crises like COVID-19, securing federal funds, and advancing priorities like coastal protection, infrastructure, and attainable housing. I’m running for Congress because our district needs practical, service-driven leadership—not performative politics. I’ve lived the challenges working families face, and I’ve spent my career solving problems, defending constitutional principles, and expanding opportunity for the people of the Lowcountry. I believe government should put people over partisanship and focus on issues that actually improve lives."

Submitted Biography: "I was born in Buffalo, NY in 2000 and have been a resident of Hanahan, SC since I entered seventh grade in 2012. I developed the itch to serve my community in the Scouting Program where I dedicated much of my time to personal growth and community service, eventually becoming an Eagle Scout. I continued my support of the Scouting Program by becoming an assistant scoutmaster in my old troop and mentoring those who came after me. After graduating from Hanahan High School in 2018 with a focus on Engineering, I earned my Aircraft Mechanic’s license and an associate degree from Trident Technical College. In 2022, I graduated from Southern Illinois University, earning a bachelor’s degree in aviation technology. I earned my Private Pilot License in 2023. As far back as Middle School, I have continuously and ardently followed news of the political, economic, and societal issues facing America. I have made it a habit to always stay educated on these issues so I could be an informed voter and an informed voice to those around me. I am a thoroughly working-class individual, with all of my formal higher education being dedicated to my blue-collar trade. I know very well what it’s like to experience the financial worries of the average American. I believe my life as a well-informed working-class citizen makes me the ideal candidate to take our issues to Washington and fight for them, tooth and nail."

Incumbent: No
Submitted Biography: "I am a proven leader, a lifelong advocate for equity, a loyal wife of a U.S. Army veteran, and a proud daughter of Puerto Rican parents who instilled in me the values of hard work, service, and resilience. I have called South Carolina home for over a decade. I am running for Congress because I believe the Lowcountry deserves a representative who listens, leads compassionately, and fights for bold, transformative change — not just partisan soundbites. I grew up in a lower-middle-class household in the heart of Puerto Rico. I watched my parents nurture their community. I was inspired to work hard, to serve, and to take action. I am a first-generation college graduate, having earned a bachelor’s in economics, a juris doctor in law, and a master’s degree in international law, foreign trade, and international relations. While my husband was on active duty, I used my knowledge of the law to serve fellow service members and their families. In South Carolina, I have worked as a community organizer, nonprofit adviser, and legal assistant at an immigration law firm. I have traveled across the state, building coalitions in rural towns and urban centers, championing reproductive rights, environmental justice, affordable health care, and public education. I am here to fight for all of us. My campaign is powered by working families, young people, veterans, and everyday South Carolinians who are ready to build a future rooted in justice, opportunity, and dignity for all."
