This study investigates how partisan donors influence congressional candidates' ideological positions. Analyzing U.S. House elections from 2002-2010, the findings reveal a significant trend: candidates show greater responsiveness to their donor base than to primary voters or general election supporters.
Candidate Responsiveness:
- Nominated candidates consistently align more with donors than other voter groups
- This effect varies by party and district competitiveness
Party Differences:
- Democratic nominees respond more strategically in safe districts
- Republican nominees demonstrate consistent responsiveness regardless of competition level
Implications:
These results highlight the polarizing influence of donor networks on American politics, ultimately shaping the ideological landscape of Congress.
