CLEP US History II

Answer: B - The 22nd Amendment to the United States Constitution, enacted in 1951, limited the number of years one may serve as President of the United States to 10 years. For most presidents, it is a de facto limit of eight years or two terms, but the amendment allows for the service of ascending vice presidents who complete the term of their president (e.g., due to assassination or resignation). If the presidential term they complete has less than two years remaining, the president can still serve two full terms to which he or she is elected in his or her own right. For example, when President John Kennedy was assassinated in November 1963, he was over halfway through his term, making his successor, Lyndon Johnson, eligible for re-election to the presidency in 1964 and 1968. However, had the law been enacted before the presidency of William McKinley, who was assassinated in 1901 (less than one year into his second term), his successor, Theodore Roosevelt, would have only been eligible for re-election in 1904.
