The Case Against Term Limits We Keep Ignoring
Decades of evidence from states that adopted term limits suggests they drain institutional expertise while doing almost nothing to check the influence of outside money or entrenched interests.
Let me stipulate what nearly every American across the political spectrum already believes: long congressional tenures create problems. Legislators who have been in office for twenty or thirty years develop relationships, obligations, and institutional habits that are not always in the public interest. Entrenched committee chairs can block legislation that a majority would support. The seniority system rewards longevity over merit. These are real phenomena and legitimate concerns.
The proposed cure — mandatory term limits — has appeal precisely because it is simple and emotionally satisfying. You throw the incumbent out before the incumbent can be captured. You refresh the institution with new blood. Problem solved. Except that decades of evidence from the thirty-six states that have adopted legislative term limits for at least one chamber tells a very different story, and almost no one in the current debate seems to be consulting it.
The most consistent finding from academic research on state legislative term limits is that they shift power away from legislators and toward the executive branch, professional lobbyists, and the permanent staff of government agencies — none of whom face term limits. A first-term state legislator confronting a policy question about, say, utility regulation or pharmaceutical pricing has almost no institutional knowledge on which to draw. The lobbyist across the table has, in some cases, been working that policy area for fifteen years. The outcome of that meeting is not difficult to predict.
This is not a theoretical concern. Political scientists who have studied term-limited states find that legislators in those states report lower confidence in their own policy expertise, higher reliance on executive-branch staff for information, and closer relationships with industry representatives who can fill the knowledge gap. In Michigan, one of the earliest and strictest term-limit states, multiple studies documented a measurable shift in budget authority from the legislature to the governor's office within a decade of implementation.
The argument for term limits usually rests on an assumption that experience in office is equivalent to capture by special interests — that the longer a legislator serves, the more beholden they become to donors and established power. But this conflates two separate phenomena. A legislator can be captured by outside money in their first term if the money arrives early enough and the accountability mechanisms are weak enough. What term limits remove is not capture; it is the ability to resist capture through accumulated understanding of how to use institutional levers, build coalitions, and navigate the legislative process without becoming dependent on the interests funding your next campaign.
The irony is that term limits tend to increase the influence of campaign money at the margins. A legislator with a safe seat and decades of goodwill in their district has less need for fundraising; a legislator who must continually rebuild their base in a competitive environment, while also lacking institutional standing, is more dependent on the resources outside money can provide. This may help explain why term-limited states have not shown measurable reductions in the correlation between donor priorities and legislative outcomes.
None of this means the concern underlying the term-limits movement is wrong. The concern — that concentrated legislative power insulates incumbents from accountability and distorts policy in favor of entrenched interests — is well-founded. But the mechanism proposed to address it consistently fails to achieve its aims while producing a set of unintended consequences that are, by now, fairly well documented. The case for term limits is, at bottom, a case built on a theory that the evidence does not support.
Better remedies — independent redistricting commissions, campaign finance disclosure requirements with real teeth, ranked-choice voting in primaries to reduce the influence of narrow ideological constituencies — are more complicated to implement and harder to sell as a simple story. That is their disadvantage. It is not a reason to prefer the remedy we know does not work.
