Scholars seek to understand campaign donor behavior and its effects on candidates. Researchers generally agree that individual donors are more ideologically extreme than most organizational donors but disagree as to whether small individual donors (those giving less than $200 per cycle) are especially correlated to extremist candidates. We study the relationship between small individual donors and legislators’ NPAT and CFscores for the California, Washington, and Oregon legislatures between 2016 and 2022. We find both that individual donors correlate to more partisan legislators in general and that the correlation between donors and politically polarized legislators is even greater for small individual donors than for large individual donors in most cases.
