Final answer:
The 22nd Amendment sets the two-term limit for U.S. Presidents and restricts anyone who has served over two years of another's term from being elected more than once.
Step-by-step explanation:
Limits on Presidential Terms
The 22nd Amendment to the U.S. Constitution establishes clear limits on the number of terms a person can serve as President. It specifically stipulates that no person can be elected to the office of the President more than twice. In addition, it also restricts anyone who has taken over the presidency and served more than two years of another's term from being elected more than once. This ensures a rotation in the presidency and prevents the consolidation of power. The amendment reflects a principle that has been observed since George Washington's voluntary two-term limit.
However, this amendment has its complexities. There are scholars who debate scenarios under which a person who is no longer eligible to be elected President could potentially be elected Vice President—this is due to the qualifications described in the Twelfth Amendment. Given such nuances, the 22nd Amendment plays a critical role in the democratic process by setting clear guidelines for presidential succession and eligibility.
