<P> "Homesteading," or securing a lifelong career in Congress, was made possible by reelection rates that approached 100% by the end of the 20th century . The concept of homesteading brought about a popular movement 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 . As they pertain to Congress, these laws are no longer enforceable, however, as in 1995, the U.S. Supreme Court overturned congressional term limits in U.S. Term Limits, Inc. v. Thornton, ruling that state governments cannot limit the terms of members of the national government . </P> <P> Where rotation in the legislative branch has withstood court challenges, term limits continue to garner popular support . As of 2002, the advocacy group "U.S. Term Limits" found that in the 17 states where state legislators served in rotation, public support for term limits ranged from 60 to 78 percent . </P> <Table> <Tr> <Th> Office </Th> <Th> Term limits </Th> </Tr> <Tr> <Td> President </Td> <Td> Limited to being elected to a total of 2 four - year terms .
