What is the maximum term a president can serve as established by the 22nd Amendment?

The correct answer is that the maximum term a president can serve is 10 years, as established by the 22nd Amendment to the U.S. Constitution. This amendment was ratified in 1951 and limits an individual to being elected to the presidency for two full terms, which is a total of 8 years. However, it also allows for a president who has served less than two years of a term to potentially serve an additional two terms. Therefore, if a vice president or other successor assumes the presidency and serves for up to 2 years, they could then run for and be elected for two additional complete terms, equating to a possible total of up to 10 years in office. This provision was intended to prevent any individual from holding the presidency for an excessively long period, reinforcing the principles of democratic governance and avoiding the risk of a permanent presidency.
