Kentucky changed the rules for filling a U.S. Senate vacancy in 2024, leaving fewer options for temporary appointment

Kentucky’s process for filling a U.S. Senate seat if a senator dies or resigns has shifted in recent years. A July 7 explainer from WLKY said that while governors previously could appoint a temporary replacement, Kentucky now must call a special election when a vacancy occurs.

Before the change, WLKY reported, Kentucky law allowed a governor to appoint an interim U.S. senator from a list provided by the departing senator’s political party, with the appointment lasting until a special election could be held. That approach meant Kentucky could retain two U.S. senators in the near term even if the seat became vacant unexpectedly.

The 2024 legislation changed that structure, according to WLKY. The report said the change was sponsored by state Rep. Steven Rudy of Paducah, and that Louisville Metro Council member Kevin Bratcher, then a former state representative, was a co-sponsor. Bratcher is quoted in the WLKY piece saying lawmakers had the idea that “we’ll just have a special election and let the voters decide.”

Under the updated rule, WLKY said, if a U.S. Senate seat becomes vacant, the governor must call a special election. Until that election is held, Kentucky would have only one sitting U.S. senator, because the law does not provide for a temporary appointment to cover the gap.

The law also includes timing rules. WLKY reported that if the vacancy happens within 56 days of an election, and there is not enough time to hold a special election, the seat would remain vacant until the next regular election rather than allowing a governor-led appointment to bridge the period.

In the WLKY report, Bratcher’s comments addressed how the new timeline could play out in practice this year. The article said that if a vacancy occurred in 2026 before the cutoff date for a special election of Sept. 8, voters would wait for the next regular election in November.

The WLKY explainer also noted that Kentucky is one of a small number of states that require a special election to fill a Senate vacancy, framing the state’s procedure as distinct from places that allow immediate appointment to maintain full representation. The report added that Bratcher said the change puts the decision in the hands of voters, not the governor, while also emphasizing that he hopes the law never has to be used.

For Kentucky residents, the practical effect of the 2024 change is that a sudden vacancy could mean a reduced delegation for months, depending on when the vacancy occurs and whether a special election can be conducted under the statutory deadlines. The governor’s obligations and the election calendar would then govern how quickly the seat can be filled.

In the meantime, the WLKY report indicates the state’s process is clear on the legal requirement to call the special election and on what happens if the vacancy timing makes that special election impossible. If the conditions apply, Kentucky’s representation would be adjusted according to the election schedule rather than through an interim appointment.
