Congressional experience linked to more constituent service in study of agency requests
A study of congressional contacts with federal agencies found that replacing an experienced lawmaker was associated with less constituent service and less policy work. The findings inform debate over term limits but do not test the policy directly.
University of Michigan researchers said in an October 7 report that experienced members of the U.S. Congress can provide more constituent service as their offices gain capacity. Their study of congressional requests to federal agencies found that when a new lawmaker replaced an experienced one, the district received less constituent service and less policy work. The finding matters to arguments about term limits, although the study did not test term-limit policies.
The study, first published online in the American Journal of Political Science on January 30, examined a part of representation that receives less attention than votes and speeches: the contacts congressional offices make with federal agencies on behalf of people and organizations. Its authors, Devin Judge-Lord, Eleanor Neff Powell and Justin Grimmer, asked whether lawmakers shift their attention toward policy work as they gain experience and institutional power, and whether growing office capacity changes what they can accomplish.
What the congressional agency requests show
The researchers assembled 611,239 requests from lawmakers to 92 federal agencies, departments and subagencies, covering 2007 through 2020. They collected the records through 434 Freedom of Information Act requests made between February 2017 and February 2024. The study therefore examines a substantial record of agency contacts, rather than every form of congressional work or every outcome for people who sought assistance.
For their comparison of service and policy work, the researchers hand-coded 511,029 requests. The paper says 71% of those coded requests were on behalf of individual constituents, 6% were for corporations and 7% were for nonprofits and local governments. General or industry-focused policy work accounted for 16%. These are categories of recorded requests, not measures of whether the offices obtained the results sought.
The authors found two patterns at once. Lawmakers in more powerful positions did more policy work, but greater office capacity allowed them to maintain or increase constituent service. Requests from committee chairs were 76% constituency service, compared with 85% for non-chairs. That difference in the mix of work does not mean chairs stopped helping constituents; the study says capacity helped offset the shift toward policy work.
The paper also found that a district received less of both kinds of agency-facing work after an experienced lawmaker was replaced by a new one. Its analysis used comparisons within lawmakers and within districts. The authors reported little evidence that constituents simply redirected their requests to more established legislators when a new representative took office. Those findings describe the researchers’ analysis of agency communications, not a count of all assistance available to a district.
Why congressional office capacity matters
In the October 7 report, Judge-Lord described a new member’s arrival as a major transition for a congressional office. He said learning the job takes time and argued that staffing and institutional knowledge affect whether lawmakers can deliver on promises of oversight and constituent service. The study’s account of replacement is consistent with that concern: changing the person who holds a seat also changes the experience available to manage its work.
Judge-Lord said offices contact agencies for a wide range of reasons. They may help veterans pursuing benefits, families and businesses navigating immigration procedures, and organizations seeking federal grants or contracts. They may also pursue broader policy questions with agencies. Those examples explain why the distinction between constituent service and policy work matters: both can be part of what an office does for its district, even when neither appears in a congressional vote.
What the findings mean for term-limit arguments
The findings complicate the claim that longer-serving lawmakers necessarily become less responsive to constituents. The researchers found that a shift toward policy work can coexist with more capacity to handle service requests. They also observed a drop in both service and policy work when an experienced lawmaker was replaced. That makes the costs of setting up a new office relevant to the debate over congressional turnover.
The evidence has clear limits. The records end in 2020 and cover communications with federal agencies, not the full quality or results of constituent assistance. The study was not designed to evaluate institutional reforms, and it did not measure what happened after term limits were adopted. It therefore cannot establish that a term-limit rule would produce the same effects in every setting or tell voters how to weigh experience against other reasons for replacing an incumbent.
