"Homesteading" in Congress, made possible by reelection rates that approached 100% by the end of the 20th century, brought about a popular insurgency known as the "term-limits movement". The elections of 1990-94 saw the adoption of term limits for state legislatures in almost every state where citizens had the power of the initiative. In addition 23 states limited service in their delegation to Congress, with the general formula being three terms [six years] in the U.S. House and two terms [twelve years] in the U.S. Senate.
As they pertain to Congress, these laws are no longer enforceable, however, as in 1995, the U.S. Supreme Court overturned congressional term limits, ruling that state governments cannot limit the terms of members of the national government.[17]
