Declares elective public office vacant when office holder changes political party while in office.

This bill declares that an elected official's position becomes vacant immediately if they switch political parties while serving in office. The officeholder must relinquish their position upon the change being declared, and the vacancy will be filled according to existing laws. The rule only applies to elected offices where political party affiliation is listed on ballots. It does not affect non-partisan offices or appointments made to fill vacancies.
