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).
Barack Obama's farewell address
In the 2016 presidential election, Obama was ineligible to seek reelection to a third term due to the restrictions of the Twenty-second Amendment. In June 2016, Obama endorsed his former Secretary of State, Hillary Clinton, to succeed him as president. He addressed the 2016 Democratic National Convention on July 27 in support of Clinton as the Democratic Party's nominee, and continued to campaign for her throughout the 2016 general election campaign season. However, Hillary Clinton would unexpectedly lose the general election to Republican nominee Donald Trump on November 8, after failing to receive enough votes in the Electoral College, despite receiving a plurality of the national popular vote. The Democratic Party would no longer control the presidency once Trump was inaugurated on January 20, 2017, and they did not have a majority of seats in either chamber of the United States Congress, and in the state legislatures and governorships. President Obama's approval ratings were nearly at 60 percent at the time of his farewell speech.
