Members of Congress strategically select committees based on their ideological preferences, not just distributive benefits or seniority. A unique dataset analyzing committee roll-call votes reveals that moderate members gravitate toward less partisan committees while those from ideologically extreme districts prefer highly partisan ones. This pattern suggests a previously underestimated role for representational gains in committee selection.

Data & Methods

Constructed an original measure of committee partisanship using comprehensive data on legislative voting patterns across all House committees.

Compared the ideological leanings of members with their chosen committee jurisdictions.

Explored how this relationship interacts with traditional distributional factors.

Key Findings

• Members tend to join committees whose ideologies align closely with their own, regardless of other considerations.

• The search for ideologically congruent committees is particularly pronounced among representatives from districts holding extreme ideological views.

• This self-selection process appears independent of a member's seniority or reputation-seeking motivations.

Ways It Matters

• Offers new insights into how members strategically position themselves in the legislative landscape.

• Resolves longstanding questions about committee selection by incorporating previously overlooked representational dynamics.

• Provides empirical evidence that descriptive representation is an equally important motivation for committee choice as distributive factors.
