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).
2016 United States Senate election in Kentucky
Paul was running for both president and re-election, and considered several options to get around the law preventing him from appearing twice on the ballot, but he dropped his presidential bid to focus on re-election to the Senate on February 3, 2016. His supporters said the law does not apply to federal offices and suggested changing the May Kentucky presidential primaries to March caucuses would allow Paul to run for re-election and continue to seek the presidential nomination. However, this option would have only worked until the presidential primaries were over, as he would still have had to appear on the ballot twice in November if he had won the Republican presidential nomination. Other options that were open to him included running for both offices and leaving it to Democratic Secretary of State Alison Lundergan Grimes to remove him from the ballot; attempting to replace Grimes in the 2015 elections with a Republican Secretary of State who would not enforce the law; filing a lawsuit against the law; and running for president in every state except for Kentucky, where he could have run for re-election and hoped to win the presidency without Kentucky's electoral college votes.
