Answer:
When a public office is left vacant due to the resignation of an official, a special election may be held to fill the vacancy. The type of special election that is held to fill the vacant office depends on the laws and regulations of the jurisdiction in question.
In some cases, a special election may be held to fill the vacancy, which is a separate election that is held outside of the regular election cycle. In other cases, the vacancy may be filled during the next regularly scheduled election.
Additionally, the type of election held to fill a vacant public office may vary depending on the specific office that is being filled. For example, a special election to fill a vacant seat in the U.S. House of Representatives is different from a special election to fill a vacant seat in the U.S. Senate.
