United States law states that no US president may be elected to more than two terms. The 22nd Amendment (1951) was adopted partly in response to Franklin D. Roosevelt's 4 consecutive terms in the middle of the 20th century. Therefore a president who has held that post for two terms is ineligible to run again.
