In Memoriam

Senator Lindsey Graham (R-SC) served the people of South Carolina in the United States Senate from 2003 until his passing on July 11, 2026 -- a span of 23 years. Before the Senate, he served four terms in the U.S. House of Representatives and six years in the U.S. Air Force Judge Advocate General's Corps, attaining the rank of Colonel and earning a Bronze Star. He chaired the Senate Judiciary Committee from 2019 to 2021 and served on the Appropriations and Budget Committees. Our thoughts are with his family and the people of South Carolina.

What Does the Constitution Actually Say?

Most Americans know how senators are elected -- but very few know what happens when one dies before their term ends. The Founders thought about this, and the answer evolved over time through constitutional amendments and state law.

Originally, Article I of the Constitution gave state legislatures the power to fill Senate vacancies. But in 1913, the 17th Amendment changed that. It established direct election of senators by the people, and it gave states the option to let their governors make temporary appointments when a seat opens up.

17th Amendment -- Ratified April 8, 1913

"When vacancies happen in the representation of any State in the Senate, the executive authority of such State shall issue writs of election to fill such vacancies: Provided, That the legislature of any State may empower the executive thereof to make temporary appointments until the people fill the vacancies by election as the legislature may direct."

In plain English: the governor of the state gets to appoint a temporary senator, and then voters elect a permanent replacement through a special election. The exact rules -- how quickly that election must happen, whether the governor must pick someone from the same party, and how long the appointee serves -- vary state by state.

The 17th Amendment to the U.S. Constitution document

The 17th Amendment, ratified in 1913, established both direct election of senators and the vacancy-filling process used today.

Why This Matters Beyond South Carolina

Senate vacancies happen more often than most people realize. In recent years alone, vacancies were triggered by the deaths of Senators John McCain (Arizona, 2018) and Dianne Feinstein (California, 2023), and by the resignation of Ben Sasse (Nebraska, 2023).

Because the Senate operates with 100 members and many key votes pass by a single-vote margin, a single vacancy can matter enormously -- to the passage of legislation, the confirmation of federal judges, and the day-to-day function of the federal government. This is why the Founders built a rapid-replacement mechanism into the constitutional framework.
