Set Consecutive-Term Limits for Congress

Average prior service of sitting members at the start of the 119th Congress in January 2025 was 8.6 years in the House and 11.2 years in the Senate (Congressional Research Service Report R41545). Twenty-three percent of the House and forty-five percent of the Senate had served more than twelve consecutive years. A 2005 Public Citizen audit found that 43 percent of the 198 members who left Congress between 1998 and 2005 and were eligible to lobby became registered lobbyists.

Current constitutional rules

The Constitution sets only minimum age, citizenship duration, and inhabitancy requirements for members of Congress (Article I, Section 2, Clause 2 for the House and Article I, Section 3, Clause 3 for the Senate). It imposes no maximum tenure. In U.S. Term Limits, Inc. v. Thornton, 514 U.S. 779 (1995), the Supreme Court held by a 5-4 majority that the Qualifications Clauses are exclusive and that neither states nor Congress may add ballot-access term limits by statute. The decision invalidated provisions in twenty-three state constitutions that had attempted to cap the service of federal members. The only remaining vehicle for a tenure cap is an amendment to the U.S. Constitution under Article V.

Article V of the Articles of Confederation provided that “no person shall be capable of being a delegate for more than three years, in any term of six years,” a cap in force from 1781 to 1789. The 1787 Constitution did not retain it, in part because the new system replaced state-legislative selection with popular election. Madison defended the change in Federalist No. 53, where he argued that two-year House terms allowed members to acquire the legislative experience that the Confederation’s frequent rotation had denied them.

The amendment

After Thornton, Article V is the only available mechanism. The amendment would be proposed by either two-thirds of both chambers or two-thirds of state legislatures calling a convention, and ratified by three-fourths of the states. H.J.Res.12 in the 119th Congress is the current vehicle for the chamber-introduced path. The proposal here caps Senate service at one consecutive term rather than two and adds a mandatory interval of elected state, county, or municipal service before any return to Congress.

The amendment text would do the following:

• Limit service in the U.S. Senate to one consecutive six-year term.
• Limit service in the U.S. House of Representatives to three consecutive two-year terms.
• Bar any former member of Congress from filing as a candidate for either chamber until at least one full federal election cycle has elapsed and the candidate has served at least one term in elected state, county, or municipal office during that interval.
• Treat any partial term that exceeds half the full term as a complete term for the purpose of the cap, consistent with the standard adopted in most state constitutional term-limit provisions.
• Apply prospectively beginning with the first congressional election held more than one year after ratification.

Precedent

At the federal level, Article V of the Articles of Confederation imposed a three-of-six-year limit on delegates from 1781 to 1789, and the Twenty-Second Amendment, ratified in 1951, imposed a two-term limit on the presidency.

Sixteen states currently impose limits on legislative service, according to the National Conference of State Legislatures: Arizona, Arkansas, California, Colorado, Florida, Louisiana, Maine, Michigan, Missouri, Montana, Nebraska, Nevada, North Dakota, Ohio, Oklahoma, and South Dakota. Six additional states enacted limits and then repealed or had them struck down. Academic and NCSL syntheses of the state experience report two consistent findings: term limits increase membership turnover, and they strengthen the relative influence of lobbyists, executive-branch officials, and legislative staff, because new members enter without independent expertise on technical subjects. The mandatory interval of state, county, or municipal service in the proposed amendment is designed to address the second finding by requiring that returning members enter Congress with recent elected governing experience.

International precedent includes both consecutive-term caps and mandatory rotation. The 1987 Constitution of the Philippines limits Senators to two consecutive six-year terms and Representatives to three consecutive three-year terms (Article VI, Sections 4 and 7). Costa Rica’s 1949 Constitution permits deputies in the Legislative Assembly to serve a single four-year term and prohibits consecutive reelection: a former deputy must sit out at least one full term before running again. From 1933 to 2013 Mexico prohibited all consecutive reelection in the federal legislature; the 2014 constitutional reform reversed that prohibition and now allows up to twelve consecutive years for federal Senators and Deputies.

First 100 days

Day one. The President issues a statement endorsing the proposed amendment and directs the White House Counsel’s office to coordinate with congressional sponsors on text and ratification strategy. The Department of Justice publishes a legal analysis stating that a constitutional amendment is the only available path to imposing tenure limits on federal members after U.S. Term Limits, Inc. v. Thornton.

Day thirty. The amendment is introduced in both chambers as a joint resolution. Companion model legislation is published for state legislatures to use in calling for a convention under Article V if congressional passage stalls. A federal interagency working group convenes to identify statutes that depend on long-tenured congressional staff or members and that may need parallel reforms to preserve institutional knowledge once the cap takes effect.

Day ninety. Both chambers hold floor votes on the joint resolution. Once two-thirds of both chambers approve, the proposal is transmitted to the states for ratification. The administration coordinates a state-by-state ratification campaign targeting three-fourths approval within seven years of submission to the states.

Effect of the amendment

The amendment caps the period over which any one member of Congress can develop sustained relationships with industry lobbyists, foreign governments, or large donors during continuous service. It conditions any return to federal service on an intervening term in elected state, county, or municipal office. That intervening-service requirement is a direct response to the state-level finding that pure term-limit regimes tend to shift influence toward unelected staff and outside lobbyists.
