In Kentucky, the Governor does not have the power to appoint a replacement. Kentucky goes without a second Senator until after the next election.
Hmm.... According (AI-see below) he does have the power to call for a special election, but I guess he can choose not to, or delay.
Kentucky law requires a special election to fill a vacant U.S. Senate seat, eliminating the option for a temporary appointment. The governor must call this special election, and until it occurs, the state would have only one sitting U.S. senator.

Process for Replacing a U.S. Senator in Kentucky
Special Election Requirement
Kentucky law mandates that a special election must be held to fill a vacant U.S. Senate seat.
The governor is responsible for calling this special election.
Elimination of Temporary Appointments
Recent changes to the law have removed the option for a temporary appointment to fill the vacancy.
This means that until the special election occurs, Kentucky will have only one sitting U.S. senator.
Context of the Law Changes
The law was updated in 2024, following a previous revision in 2021 that allowed for temporary appointments.
The 2024 revision reflects a shift towards allowing voters to decide on their representation.
Timing Considerations
If a Senate seat becomes vacant close to an upcoming election, such as within 56 days, it may complicate the special election process.
For instance, if a vacancy occurs shortly before a scheduled election, there may not be enough time to conduct a special election.
This structured approach ensures that the citizens of Kentucky have a direct say in who represents them in the U.S. Senate
