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).
Kamala Harris 2020 presidential campaign
If elected, Harris would be only the fourth sitting Senator elected president, the only others being Warren G. Harding, John F. Kennedy, and Barack Obama. Harris would also be the third president to have served as a state attorney general, the others being Martin van Buren (New York Attorney General, 1815-1819) and Bill Clinton (Arkansas AG, 1977-1979). If elected, Harris would be the second consecutive Democratic president to be elected as a freshman Senator, the first being Barack Obama.
