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).
Twentieth Amendment to the United States Constitution
The result of these scheduling decisions was that there was a long, four-month lame duck period between the election and inauguration of the president. For Congress, the situation was perhaps even more awkward. Because Article I, Section 4, Clause 2 mandated a Congressional meeting every December, after the election but before Congressional terms of office had expired, a lame duck session was required by the Constitution in even-numbered years; the next session wasn't required until the "next" December, meaning that new members of Congress might not begin their work until more than a year after they had been elected. Special sessions sometimes met earlier in the year, but this never became a regular practice, despite the Constitution allowing for it. In practice, Congress usually met in a long session beginning in Decembers of odd-numbered years, and in a short lame duck session in December of even-numbered years.
The long lame duck period might have been a practical necessity at the end of the 18th century, when any newly elected official might require several months to put his affairs in order and then undertake an arduous journey from his home to the national capital, but it eventually had the effect of impeding the functioning of government in the modern age. From the early 19th century onward, it also meant that a lame duck Congress and presidential administration would fail to adequately respond to a significant national crisis in a timely manner. Each institution could do this on the theory that at best, a lame duck Congress or administration had neither the time nor the mandate to tackle problems, whereas the incoming administration or Congress would have both the time, and a fresh electoral mandate, to examine and address the problems that the nation faced. These problems very likely would have been at the center of the debate of the just completed election cycle.
