Family Succession

Our most recent book is The Comeback: The 2024 Elections and American Politics. It includes a chapter on congressional and state elections.  The sudden death of Lindsey Graham was a shock to the system.

A total of 48 women have been elected or appointed to fill congressional vacancies created by the deaths of their husbands, 8 to the U.S. Senate and 40 to the U. S. House of Representatives.

Less often, other family members have succeeded deceased lawmakers:  According to Claude:

Here's a rundown, organized by relationship, of family members other than widows who directly succeeded a deceased House member or senator (via special election or gubernatorial appointment):

Sister succeeding brother: Darline Graham Nordone was appointed just this week (July 13, 2026) by South Carolina Gov. Henry McMaster to fill the Senate seat of her brother, Sen. Lindsey Graham, who died suddenly on July 12. Graham never married or had children; McMaster's pick to serve out the remainder of his term, which runs through January 2027, is his adopted-and-raised younger sister. She's set to be the first woman to represent South Carolina in the U.S. Senate. CBS News 

• Sons succeeding fathers: John Dingell Jr. won a 1955 special election to succeed his father, John Dingell Sr., in Michigan's 15th District — beginning a Dingell family run in that seat that lasted decades. Wikipedia: John Dingell
• Donald Payne Jr. won a 2012 special election to succeed his father, Donald Payne Sr., in New Jersey's 10th District. Payne won the general election 56-44 percent and never faced a competitive race again. Wikipedia: Donald Payne Jr. Insideelections

Daughters succeeding fathers:

• Adelita Grijalva was elected in 2025 to succeed her father, Rep. Raul Grijalva (D-AZ), after his death — though her swearing-in was delayed several weeks by Speaker Mike Johnson during a government shutdown. House.gov coverage / AP via WSB-TV WSB-TV
• Marcye Scott is currently running (special election set for July 28, 2026) to succeed her father, the late Rep. David Scott (D-GA), who died in April 2026 — not yet resolved, but worth flagging since it's live right now. WSB-TV

Daughter succeeding mother: Erica Lee Carter won a November 2024 special election to succeed her mother, Rep. Sheila Jackson Lee (D-TX), after Jackson Lee's death from pancreatic cancer — the first (and so far only) daughter to succeed her mother in Congress.
