Which amendment addresses presidential and vice presidential vacancies?

The Twenty-Fifth Amendment of the United States Constitution specifically addresses presidential and vice presidential vacancies. Ratified in 1967, this amendment outlines the procedures for filling a vacancy in the office of the President and Vice President. It establishes that if the President is removed from office, dies, or resigns, the Vice President shall become President. Additionally, it includes procedures for selecting a new Vice President in the event of a vacancy in that office, which must be confirmed by a majority vote of both houses of Congress.

The other amendments mentioned do not pertain to the succession or vacancy of the presidency or vice presidency. The Twenty-Sixth Amendment grants 18-year-olds the right to vote; the Twenty-Seventh Amendment deals with congressional pay changes; and the Twenty-Fourth Amendment prohibits poll taxes in federal elections. Each of these amendments addresses other aspects of governance and civil rights, but they do not cover the specific issue of presidential or vice presidential vacancies, thereby highlighting the unique role of the Twenty-Fifth Amendment in this context.
