Twenty-second Amendment to the United States Constitution
As worded, the primary focus of the 22nd Amendment is on limiting individuals twice elected to the presidency from being elected again. Due to this, several issues could be raised regarding the amendment's meaning and application, especially in relation to the 12th Amendment, ratified in 1804, which states, "But no person constitutionally ineligible to the office of President shall be eligible to that of Vice-President of the United States". While it is clear that under the 12th Amendment the original constitutional qualifications of age, citizenship, and residency apply to both the president and vice president, it is unclear whether someone who is ineligible to be elected president could be elected vice president. Because of this apparent ambiguity, there may be a loophole in the 22nd Amendment whereby a two-term former-president could be elected vice president and then succeed to the presidency as a result of the incumbent's death, resignation, or removal from office (or even succeed to the presidency from some other stated office in the presidential line of succession).
Presidency of Dwight D. Eisenhower
The 22nd Amendment to the U.S. Constitution, ratified in 1951, established a two-term limit for the presidency. As the amendment had not applied to President Truman, Eisenhower became the first president constitutionally limited to two terms. Eisenhower nonetheless closely watched the 1960 presidential election, which he viewed as a referendum on his presidency. He attempted to convince Secretary of the Treasury Robert Anderson to seek the Republican nomination, but Anderson declined to enter the race. Eisenhower offered Nixon lukewarm support in the 1960 Republican primaries. When asked by reporters to list one of Nixon's policy ideas he had adopted, Eisenhower joked, "If you give me a week, I might think of one. I don't remember." Eisenhower and Nixon in fact had become unequal friends, who learned it from each other and respected each other. Despite the lack of strong support from Eisenhower, Nixon's successful cultivation of party elites ensured that he faced only a weak challenge from Governor Nelson Rockefeller for the Republican nomination.
