How did the Twenty-Second amendment limit the presidency?

The Twenty-Second Amendment, ratified in 1951, specifically limits the presidency by setting a maximum term limit for the President of the United States. It states that no person can be elected to the presidency more than twice, and if a person has served more than two years of someone else's term, they can only be elected once.

Here are the key ways the amendment limits the presidency:

1. Term limits: The most significant limitation imposed by the amendment is the establishment of term limits. Previously, there was no legal barrier preventing a President from being re-elected an unlimited number of times, as exemplified by Franklin D. Roosevelt's four terms in office. The amendment ensures that no person can serve as President for more than two elected terms, providing a safeguard against potential abuses of power and preventing the accumulation of excessive executive authority.

2. Succession clarification: The amendment also clarifies the line of succession in case a Vice President assumes the presidency. It specifically states that if a Vice President serves as President for more than two years of a term to which someone else was elected, that Vice President can only be elected once on their own. This provision prevents a Vice President who assumes the presidency from serving two full terms as President, effectively extending their tenure beyond the intended period.

3. Timing of adoption: The amendment applies only to future presidents and cannot be applied retroactively. Therefore, Presidents who were in office prior to the amendment's ratification, like Harry S. Truman, were not affected by its provisions and were still eligible for reelection.

In short, the Twenty-Second Amendment limits the presidency by instituting term limits, clarifying succession rules in specific situations, and establishing a maximum number of terms a President can serve. It aims to prevent individuals from holding the presidency for an excessive period, ensuring a rotation of leadership and preventing the concentration of power in a single individual.
