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.[3][4]

For information about which offices are nominated via primary election, see this article.

This page focuses on South Carolina's 1st Congressional District Democratic primary. For more in-depth information on the district's Republican primary and the general election, see the following pages:

Submitted Biography "At 34 years old, I represent a new wave of American leadership. I served honorably in the U.S. Coast Guard as a federal law enforcement officer and search and rescue crewman. Later, I went on to graduate from The Citadel and Charleston School of Law, and will soon complete my MBA from the University of North Carolina at Chapel Hill. My experience spans both corporate and public sectors. As an attorney, I advised top executives for a publicly-traded software company in Charleston, then later served as Associate General Counsel for the Town of Mount Pleasant and General Counsel for the Town of Hilton Head Island. With a foundation built on service, I am eager to bring forward-thinking solutions to the challenges of our times."

Service Beyond Self. From my service in the U.S. Coast Guard to tackling complex issues for some of South Carolina's most notable municipalities, I've consistently put people first. This unwaivering commitment to public service is what drives my desire to serve South Carolina's 1st Congressional District in Washington.


A New Era of Leadership. Representing a new generation doesn't just mean a change in age, but a change in vision and approach. I'm commitment to transparent and innovative leadership to find solutions to the challenges of our times.


Actions Over Words. From the Coast Guard to serving our communities as a lawyer, I stand for leadership that doesn't just plan, but actively executes and delivers for every member of our community.

Key Messages

To read this candidate's full survey responses, click here.


Defending Our Democracy: It's a perilous moment for American democracy. Respect for the rule of law is eroding. Partisan gerrymandering and election lies have undermined voting rights across the country. Too many politicians are putting party first, and too many families are feeling left behind, distrusting of institutions. Meanwhile, our lawmakers are turning inward — refusing to come together and collaborate on commonsense solutions for the Lowcountry. In Congress, I'll work to help bridge these divides, restore faith in our government, and rehabilitate U.S. democracy in the 21st century.


Putting People Over Politics: Our representatives in Washington spend too much time chasing cable news appearances, embracing extremist policies, and stoking the flames of partisanship. It's time for a leader who will put the needs of their constituents over the whims of their party. As a results-focused businessman, I'm ready to get to work on behalf of the people of this district — not the politicians in D.C.


Commitment to Public Service: Public service runs in my blood. I come from a long line of pioneering lawmakers and civil rights leaders, and I'm committed to building upon the hard-fought victories my forefathers secured for future generations of South Carolinians when I'm elected to Congress.

Post-filing deadline analysis

The following analysis covers all U.S. House districts up for election in South Carolina in 2024. Information below was calculated on April 23, 2024, and may differ from information shown in the table above due to candidate replacements and withdrawals after that time.

Twenty-nine candidates ran for South Carolina’s seven U.S. House districts, including 11 Democrats and 18 Republicans. That’s 4.14 candidates per district, more than the four candidates per district in 2022 and the 2.86 candidates in 2020.

The 3rd Congressional District was the only open district, meaning the incumbent did not file to run. The only other election cycle this decade when an incumbent did not run for re-election was 2018.

Incumbent Jeff Duncan (R-3rd) did not run for re-election because he is retired from public office.

Nine candidates—two Democrats and seven Republicans—ran for the open 3rd Congressional District, the most candidates that ran for a seat in South Carolina in 2024.

Nine primaries—four Democratic and five Republican—were contested in 2024, tying with 2018 for the most this decade.

Three incumbents—Nancy Mace (R-1st), Joe Wilson (R-2nd), and William Timmons (R-4th)—were in contested primaries.

Candidates filed to run in the Republican and Democratic primaries in all seven districts, meaning no seats were guaranteed to either party.
