Twenty-second Amendment to the United States Constitution
The amendment prohibits any individual who has been elected president twice from being elected again. Under the amendment, an individual who fills an unexpired presidential term lasting greater than two years is also prohibited from winning election as president more than once. Scholars debate whether the amendment prohibits affected individuals from succeeding to the presidency under any circumstances or whether it only applies to presidential elections.
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.
