After Franklin D. Roosevelt had served four terms as president, the Twenty-second Amendment to the Constitution was enacted, limiting future presidents to two 4-year terms. U.S. senators are elected for six-year terms, and they can be reelected to that office indefinitely.
What was the effect of the Twenty-second Amendment?
Explanation
The two-term limit is part of the system of checks and balances, which prevents any individual (for example, the president) or group of individuals from gaining too much power in the nation. Conversely, the two-term limit gives Congress more power.
