How Term Limits Work: Where They Apply and Where They Don't
A voter frustrated with an incumbent who has held a Senate seat for thirty years often assumes there must be some rule against it. There isn't, at the federal legislative level, and the reason reveals a lot about how differently the founders and later reformers treated different offices.

The Twenty-Second Amendment, ratified in 1951 after Franklin Roosevelt won four consecutive presidential elections, bars anyone from being elected president more than twice, and limits a vice president who succeeds to the office partway through a term and serves more than two years of it to a single additional elected term. The amendment closed a gap the founders had deliberately left open — Washington's decision to step down after two terms had been a personal precedent, not a legal requirement, and it held for a century and a half purely through political norm rather than constitutional text. Roosevelt's four elections broke that norm, and Congress responded by writing the limit into the Constitution itself, which means changing it requires another constitutional amendment rather than an ordinary statute.
Congress: No Limit at All
Members of the House and Senate face no term limits whatsoever under federal law, and attempts to impose them have run into a firm constitutional wall. In the 1995 case U.S. Term Limits v. Thornton, the Supreme Court struck down state-imposed term limits on that state's own congressional delegation, ruling that the Constitution's qualifications for House and Senate service — age, citizenship, and residency — are fixed and exclusive, and that neither states nor Congress itself can add to them without a constitutional amendment. Several states had passed such limits through ballot initiatives in the early 1990s specifically to test the idea, and the ruling invalidated all of them at once. Since then, congressional term limits have existed only as a recurring proposal, not as enforceable law, and any serious version of it would require ratification by three-quarters of the states.
State Legislatures: A Patchwork by Design
Unlike Congress, state legislatures can and do impose term limits on themselves, since state constitutions are not bound by the federal qualifications clause the way congressional seats are. Roughly fifteen states currently limit how long a person can serve in the state house, state senate, or both, with most of these limits adopted through ballot measures during a wave of term-limit initiatives in the 1990s. The specifics vary enormously: some states impose a lifetime cap on total years served in a chamber, others allow a person to return to the same seat after sitting out a set number of years, and a few states that once had term limits have since repealed or loosened them through later legislative or voter action. This variation connects directly to how political parties recruit and retain candidates, since term limits change the incentive for building a long career in a single legislative seat versus using it as a stepping stone to statewide office.
Governors and Other Statewide Offices
Most states limit governors to two consecutive terms, though the exact rule again varies: some allow a governor to return after sitting out one term, others impose an absolute lifetime cap, and a handful of states place no limit on the governorship at all. Limits on other statewide offices, like attorney general or secretary of state, follow no consistent national pattern and depend entirely on that state's own constitution or statutes. This patchwork means a governor term-limited out of office in one state might, in principle, be eligible to run again after a gap that would be flatly impossible under a neighboring state's rules.
The Underlying Argument, Which Never Really Settles
Supporters of term limits argue they reduce the advantages of incumbency, encourage turnover, and prevent any one official from accumulating the kind of entrenched influence that makes a legislature or executive branch unresponsive to voters. Opponents argue that term limits push out experienced legislators just as they are learning how the institution actually works, shift power toward staff and lobbyists who outlast any term-limited official, and remove a check that voters already have available every election cycle if they choose to use it. Neither argument has produced a consistent nationwide answer, which is part of why the current patchwork — hard limits for the presidency, none for Congress, and a state-by-state mix everywhere else — has persisted largely unchanged for decades.
