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).
African-American candidates for President of the United States
Major party African American candidates for President of the United States could not run in primaries until nearly the third quarter of the 20th century, after the passage of the Civil Rights Act (1964) and Voting Rights Act (1965) opened up political participation to blacks in the South. In addition, party changes to give more weight to candidates' performance in primaries, rather than to party leaders' negotiation in secret, opened up the fields. In 2008, Senator Barack Obama was elected the 44th president of the United States, the first African American to win the office.
