What Would It Take to Put Term Limits on Congress?
Meta description: Learn how Congress could be subject to term limits, why states cannot impose them on their own, and what an amendment would need to address.
Putting term limits on Congress would require more than a federal law or a state-by-state campaign. The Constitution sets no limit on how many times a person may be elected to the House or Senate, and the Supreme Court has ruled that states cannot add their own congressional eligibility restrictions. The most direct path is a constitutional amendment, which requires broad support in Congress and across the states. A convention proposed by the states is another route, but it has never been used to send an amendment to the states for ratification.
What Congressional Term Limits Would Change
Congressional term limits would restrict how many terms a person could serve in the U.S. House of Representatives, the U.S. Senate, or both. The details would depend on the exact policy: a limit might apply separately to each chamber, combine service in both chambers, or cap total years in Congress.
Currently, the Constitution contains no term limit for members of Congress. House members serve two-year terms, while senators serve six-year terms. Voters may reelect an incumbent as often as they choose, provided that person continues to meet the Constitution’s qualifications and wins each election.
Term limits would therefore change the rules of eligibility, not the length of a congressional term. Unless an amendment also changed term lengths, House elections would still occur every two years and Senate elections would continue on a staggered six-year cycle.
Why Congress Cannot Simply Pass a Term-Limits Law
A regular federal statute cannot override the Constitution’s eligibility rules. Congress could pass laws governing many aspects of federal elections, but it cannot use an ordinary law to add a new qualification for serving in the House or Senate.
The Supreme Court addressed this issue in U.S. Term Limits, Inc. v. Thornton in 1995. Arkansas had adopted a measure intended to prevent candidates who had served a specified number of congressional terms from appearing on the ballot. The Court ruled that states could not impose additional qualifications for members of Congress beyond those in the Constitution.
The decision means a state cannot independently limit how long its U.S. representative or senator may serve. States administer congressional elections, but that authority does not let them change who is constitutionally eligible for the office. The Court also rejected the idea that voters in one state could create a new qualification that applies only to their own representatives.
Congressional term limits would require a constitutional basis. In practice, that means amending the Constitution rather than relying on a state law, a congressional rule, or a federal statute.
The Constitutional Amendment Process
Article V of the Constitution provides two ways to propose an amendment and one way to ratify it. Either proposal route requires approval from three-fourths of the states for the amendment to become part of the Constitution.
Route One: Congress Proposes an Amendment
Congress can propose a constitutional amendment when two-thirds of the members voting in each chamber approve it. That means the House and Senate must each reach the required two-thirds threshold. The president does not sign or veto a proposed constitutional amendment.
After Congress proposes an amendment, Congress specifies whether ratification will occur through state legislatures or through state conventions. Ratification requires approval from three-fourths of the states: 38 of the 50 states under the current total.
This route has been used for every amendment in the Constitution. For a congressional term-limits amendment, lawmakers would need to agree on the policy language, secure the necessary supermajorities in both chambers, and then win ratification in 38 states.
Route Two: States Request a Convention
Article V also directs Congress to call a convention for proposing amendments when the legislatures of two-thirds of the states—currently 34—apply for one. A convention could propose a congressional term-limits amendment, but the proposal would still need ratification by 38 states.
No convention called under this provision has ever proposed an amendment. Important questions about how a convention would operate, what subjects it could consider, and how its delegates would be selected remain unsettled. Supporters may view this route as a way to apply pressure when Congress does not act; others worry about uncertainty over the convention’s scope and procedures.
A state application does not itself amend the Constitution. It contributes to the threshold for asking Congress to call a convention, and any amendment proposed by that convention would face the same state-ratification requirement as an amendment proposed by Congress.
What an Amendment Would Need to Specify
“Term limits for Congress” describes a goal, not a complete legal rule. An amendment would have to define which offices it covers, how service is counted, when limits take effect, and how it applies to lawmakers already in office.
| Design question | Why it matters |
|---|---|
| Separate limits or a combined cap | A rule could set one maximum for House service and another for Senate service, or count years in both chambers together. |
| Terms or years | A limit based on completed terms is easy to state, while a years-of-service cap may address partial terms differently. |
| Partial terms | The amendment would need to say whether finishing a predecessor’s term counts as a full term, part of a term, or not at all. |
| Interrupted service | It should clarify whether leaving Congress and returning later resets, pauses, or continues the service count. |
| Effective date | Transition rules would determine whether current members’ prior service counts and when the new limit begins to apply. |
| Enforcement | The text should identify how ineligible candidates are handled, while preserving consistent election rules nationwide. |
These choices can significantly change the policy’s effect. For example, a combined limit could prevent a former House member from beginning a full Senate career after reaching the House cap. Separate limits could allow a person to serve the maximum in each chamber.
How Existing Members Might Be Treated
Transition rules are among the most consequential parts of a term-limits proposal. An amendment could count all congressional service completed before ratification, count only service after a future date, or use a gradual phase-in. Each option would affect current members differently.
If previous service counts immediately, some sitting lawmakers could become ineligible to run in the next election. If only future service counts, established members would have more time before reaching the cap. A phase-in could soften the transition but make the rules more complicated.
The amendment would also need to say whether limits apply to a member elected before the amendment takes effect but serving afterward. Clear language matters because disputes over eligibility could affect candidate filings, ballots, and election administration.
Common Arguments About Congressional Term Limits
Supporters often argue that term limits could reduce the advantage of incumbency, create more opportunities for new candidates, and encourage turnover in Washington. They may also contend that representatives who know they cannot serve indefinitely will be less focused on building long-term political careers.
Critics respond that elections already allow voters to remove members, and that term limits would restrict voters’ choices even when an incumbent remains popular. They also argue that experience and policy knowledge can be valuable in a complex legislature.
Another concern is the balance of influence. If elected lawmakers have less time to develop expertise, lobbyists, executive-branch officials, congressional staff, or other experienced participants might have greater influence over policy. The size of that effect would depend on the limit’s design and on how congressional institutions adapt.
Term limits would not automatically change campaign finance rules, district boundaries, congressional committee structures, or the influence of political parties. Those are separate questions, though they could affect how term limits work in practice.
What States and Voters Can Do
States cannot impose binding term limits on their own members of Congress under the Supreme Court’s decision in Thornton. They can, however, express support for a constitutional amendment, petition Congress, and have their legislatures submit applications seeking an Article V convention.
Voters can ask candidates and elected officials to state which limits they support and how they would handle partial terms, prior service, and transition rules. They can also evaluate whether a proposal specifies separate House and Senate caps or a combined limit. Those details matter more than a general promise to support “term limits.”
Congressional proposals and advocacy campaigns may use different definitions of term limits. Before comparing proposals, readers should check the actual text, confirm whether it is an amendment or an ordinary bill, and distinguish a proposal from a measure that has cleared Article V’s demanding approval process.
The Practical Hurdle
The central challenge is not writing a term-limit rule; it is building the national agreement required to change the Constitution. A congressional proposal needs two-thirds approval in both chambers, followed by ratification in 38 states. The alternative convention route requires applications from 34 state legislatures, a convention proposal, and ratification in 38 states.
Any workable amendment would also need precise language on service limits, counting rules, and transition dates. Until an amendment is ratified, congressional service remains unlimited by federal term caps, and states cannot add their own restrictions on who may serve in the House or Senate.
