What is the length of time an elected official stays in office?
It's not a question, but I'll answer it anyway. The time an elected official stays in office is determined by the term length of the office, which varies from one government to another, the number of times the person is elected, and if/when the person is forced out of office, due to death, term limit if any, etc., or resigns. A person cannot be elected U. S. President more than twice, and a person who has served at least two years of a presidential term to which he/she was not elected cannot be elected President more than once.
